if you have a 2 kg object and a 3 kg object separated by a distance of 4 meters, what is the gravitational force drawing them together?

Answers

Answer 1

The gravitational force drawing them together is 2.5 × 10⁻¹² N, if the masses of objects are 2 kg and 3 kg and they are separated by 4 meter distance.

Mass of the first object, m₁ = 2 kg

Mass of the second object, m₂ = 3 kg

The distance between them, d = 4 m

Universal gravitational constant, G = 6.67 × 10⁻¹¹ Nm²/kg²

The gravitational force is formulated as, F = Gm₁m₂/d²

F = (6.67 × 10⁻¹¹)(2 × 3)/4²

F = 2.5 × 10⁻¹¹ N

This force is an attractive force and it will be experienced by both the object.

Answers

The distribution of the top and bottom charges for both pieces of the foil is as below. The initial charge distribution is determined by the movement of electrons from the charged PVC pipe to the aluminum foil pieces.

(a) (1) When the charged PVC pipe is nearby, electrons are transferred from the PVC pipe to the aluminum foil pieces due to the difference in their electrical potential. This results in one piece of foil becoming positively charged and the other piece becoming negatively charged.

(a) (ii) When the charged PVC pipe is moved away, the charges on the aluminum foil pieces will remain unchanged because the charges are now separated and will not interact with each other. The distribution of charges on the two pieces of foil will remain constant until another charged object is brought into close proximity.

(b) The initial charge distribution is determined by the movement of electrons from the charged PVC pipe to the aluminum foil pieces, resulting in one piece becoming positively charged and the other negatively charged. The final charge distribution is determined by the separation of charges on the foil pieces and the lack of interaction between the charges. The charges on the foil pieces will remain constant until they are affected by another charged object.

Two carts (100 g and 150 g) on an air track are separated by a compressed spring. The spring is released. Represent the process with a momentum bar chart (a) with one cart as the system and (b) with both carts as the system. (c) Write expressions for all of the physical quantities you can from this

Answers

Answer:

The momentum bar chart is a tool used to track the changes in momentum of objects in a system over time.

(a) With one cart as the system:

Initial Momentum: m1v1

Final Momentum: m1v1'

Change in Momentum: m1(v1' - v1)

(b) With both carts as the system:

Initial Momentum: m1v1 + m2v2

Final Momentum: m1v1' + m2v2'

Change in Momentum: (m1 + m2)(v1' + v2' - v1 - v2)

The above expressions represent the changes in momentum of the carts, where m1 and m2 are the masses of the carts, v1 and v2 are their initial velocities, and v1' and v2' are their final velocities. The expressions can be used to calculate the net force acting on the carts using Newton's second law, F = Δp/Δt, where Δp is the change in momentum and Δt is the change in time.

Physical quantities that can be calculated from this scenario include the initial and final momentum of the carts, the change in momentum, the net force acting on the carts, and the acceleration of the carts.

A. Increases
B. Decreases
C. Remains the same

Answers

Solid water becomes a liquid when the pressure increases isothermally. The entropy of the water   Increases

This is because the increase in pressure causes the water molecules to gain more thermal energy and become more disordered.

This results in an increase in entropy, as the number of available microstates for the water molecules has increased.

In general, an increase in temperature or pressure results in an increase in entropy, as it promotes a greater degree of disorder and randomness in the system.

Conversely, a decrease in temperature or pressure will result in a decrease in entropy, as it promotes a greater degree of order and stability in the system.

does a heat flux vector at a point p on an isothermal surface of a medium have to be perpendicular to the surface at that point? explain.

Answers

A heat flux vector at a point p on an isothermal surface of a medium must be perpendicular to the surface at that point.

For differentiation between heat flux, there are three categories: convection, conduction, and radiation. For an isothermal surface, the heat flux must be normal to that surface at any point P. This is because the gradient of temperature on the isothermal surface in any direction parallel to the isothermal surface will be zero, thus the heat flux in the direction parallel to the surface area will not be there. The heat flux vector is directed towards regions of lower temperature. So, a heat flux vector at a point p on an isothermal surface of a medium must be perpendicular to the surface at that point.

Answers

The average acceleration of the egg while falling can be calculated using the equation a = (v - u)/t, where v is the final velocity, u is the initial velocity and t is time.

The average acceleration

a) A = (11.0 m/s) / (1.12 s) = 9.82 m/s^2

b) A = (0 m/s) / (0.131 s) = 0 m/s^2

This is a physics problem involving the concepts of acceleration, velocity, and time.Acceleration is the rate of change of velocity and is a vector quantity, meaning it has both a magnitude and direction.In this case, v = 11.0 m/s, u = 0 m/s and t = 1.12 s.This gives an acceleration of 9.82 m/s^2 downwards, the same value as the acceleration due to gravity.The average acceleration of the egg while stopping can be calculated using the same equation, but with v = 0 m/s, u = 11.0 m/s and t = 0.131 s.This gives an acceleration of -84.3 m/s^2, which is an acceleration directed upwards, opposite to the acceleration due to gravity.In summary, the egg experienced an average acceleration of 9.82 m/s^2 downwards while falling, and an average acceleration of -84.3 m/s^2 upwards while stopping.

a bicycle pump contains 0.650 l of air at 101 kpa. if the pump is sealed, what pressure is required to change the volume to 0.250 l?

Answers

The pressure required to change the volume from 0.650 L to 0.250 L is 298 kPa. We can find out using Ideal Gas Law.

The ideal gas law states that the pressure, volume, and temperature of a gas are related by the equation:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in kelvins.

Since the temperature is constant, we can simplify the equation to:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume. Rearranging the equation gives:

P2 = P1 * (V1 / V2)

Substituting in the known values, we find:

P2 = 101 kPa * (0.650 L / 0.250 L) = 298 kPa

Therefore, pressure is 298kPa.

New York at 3:45 pm. The distance travelled is 3,450 kilometers. Determine the average speed of the plane in m/s.

Answers

Answer:

sorry i am late

Explanation:

To determine the acceleration of the car, we can use the formula: acceleration = (final velocity - initial velocity) / time. In this case, the initial velocity is 0 (the car is stopped), the final velocity is 88 mph, and the time is 6 seconds. So: acceleration = (88 - 0) / 6 = 14.67 mph/s.

a) The forces working on the plane as it moves across the sky include thrust from the engines, lift generated by the wings, weight (or gravity), and drag (air resistance).

b) The plane does not move towards the surface of the earth because the lift generated by the wings is greater than the weight (or gravity) pulling the plane down.

c) If the speed of the plane slows down to zero, the plane will begin to fall towards the surface of the earth. This is because the lift generated by the wings depends on the speed of the plane and at zero speed, there is no lift to counteract the weight of the plane.

To determine which of the two options has the fastest speed, we need to convert the speed of the dog to m/s. 3.5 km/hr is equivalent to 0.978 m/s. Therefore, the cat (with a speed of 4 m/s) is faster than the dog.

To determine the average speed of the plane, we can use the formula: average speed = distance traveled / time taken. The distance traveled is 3,450 kilometers, and the time taken is 3 hours and 30 minutes (or 3.5 hours in decimal form). So: average speed = 3,450 / 3.5 = 985.71 km/h. To convert this to m/s, we can multiply by 1000/3600 = 0.277 m/s. So the average speed of the plane is 0.277 m/s

the gases from 2.0 atm to 0.25 atm at 389 K?
A) 8 hours B) 72 hours
C) 192 hours D) 288 hours

Answers

The time required to drop the pressure of one of the gases from 2.0 atm to 0.25 atm at 389 K is 288 hours, or Option (D).

For a first order reaction, the change in pressure of a gas is proportional to its initial concentration and to the rate constant of the reaction. The half-life of a first order reaction is defined as the time required for the concentration of a reactant to decrease to half its initial value.

The rate constant (k) of a first order reaction can be related to its half-life (t1/2) as follows:

k = 0.693 / t1/2

We can use this relationship to find the rate constant for our reaction:

k = 0.693 / 24 hours = 0.0289 h^-1

Next, we can use the rate constant to find the time required for the pressure of one of the gases to decrease from 2.0 atm to 0.25 atm:

P = P0 * e^(-kt)

ln(P/P0) = -kt

-t = ln(P/P0) / k

where P0 is the initial pressure, P is the final pressure, t is the time, and e is the base of natural logarithms.

Plugging in the values, we get:

-t = ln(0.25/2.0) / 0.0289 h^-1

t = 288 hours

Therefore, the time required to drop the pressure of one of the gases from 2.0 atm to 0.25 atm at 389 K is 288 hours, or Option D).

There are two ions in the compound LiBr (Lithium Bromide). These are

Lithium-ion ([tex]Li^{+1}[/tex]).Bromide-ion ([tex]Br^{-1}[/tex]).

The lithium atom (Li) removes one electron from its valence shell to form the cation, Lithium-ion ([tex]Li^{+1}[/tex]). The Bromine atom (Br) accepts one electron to its valence shell to form the anion, Bromide-ion ([tex]Br^{-1}[/tex]).

Cations are positively charged and anions are negatively charged.

It is known that opposite charge always attracts each other. So, [tex]Li^{+1}[/tex] and [tex]Br^{-1}[/tex] attracts each other to form the ionic compound, Lithium Bromide (LiBr).

Simplify the following expression in terms of the dimensions mass, length, and time given by [M], [L], and [T].

[M][L]^2/[t]^2 . [T]/[L] = ?

a. [M] [L]/[T]^2
b. [M] [L]/[T]
c. [T][L]/[M]
d. [M] [T]/[L]
e. [M][L]^2/[T]

Answers

The required solution of the dimensional formula is calculated to be [M][L]/[T]. Correct option is B.

Dimensional analysis is the practice of checking relations between physical quantities by identifying the dimensions of the physical quantities.

If Q is the unit of a derived quantity represented by Q = M^a L^b T^c, then M^a L^b T^c is called the dimensional formula and the exponents a, b, and c are called the dimensions.

The given expression is the multiplication of dimensional formulae of two different physical quantities.

We know that,

Mass m = [M]

Length l = [L]

Time t = [T]

The given expression to solve is,

[M][L]²/[T]² . [T]/[L] = [M][L]/[T]

Thus, the required solution of the given expression is [M][L]/[T].

which is a possible unsafe consequence of using fin material that is too thin or weak for your rocket and the motor that you are using?

Answers

Using fin material that is too thin or weak for a rocket and its motor can result in fin failure, trajectory instability, motor damage, and loss of control.

Fin failure: Thin or weak fins may not be able to withstand the aerodynamic forces and stresses during launch, which can result in fin failure.

Trajectory instability: Weak or poorly designed fins can cause trajectory instability, making the rocket unpredictable and potentially dangerous.

Motor damage: In some cases, using weak or improperly designed fins can lead to excessive stress on the motor casing, causing damage and potentially leading to a motor failure.

Loss of control: If fins fail or the rocket becomes unstable, it may become uncontrollable and fall back to the ground, potentially causing damage or injury.
