Define velocity

The main determinant of an object's location and rate of motion is its velocity. It can be explained as the distance an object travels in one measure of time. The displacement of the item in a given amount of time is referred to as velocity.

The distance a person travels in a predetermined amount of time is referred to as speed.

Vi is the starting speed.

Vf is final speed

A=acceleration and Y=displacement

When the bag is freed, its Vi equals that of a balloon traveling at 13 m/s upward.

At the moment of release, choose up as positive y=0.

Vf=0 when it is maximum. Using the equation 2Vf=2Vi+2ay,

The movement of plates is explained by the theory of plate tectonics, which proposes that the Earth's lithosphere (made up of rigid plates) moves slowly over the underlying, more fluid asthenosphere due to the circulation of heat from the Earth's interior

What is Tectonics Plates?

Tectonic plates are large pieces of the Earth's lithosphere (made up of the crust and uppermost part of the mantle) that move around on the underlying asthenosphere, a more fluid layer of the mantle. The lithospheric plates are rigid and brittle, and they move in response to forces generated by the circulation of heat in the Earth's interior. The movement of the plates causes many geological features such as mountains, volcanoes, earthquakes, and oceanic trenches.

There are several major and minor tectonic plates, including the Pacific Plate, the North American Plate, the African Plate, the Eurasian Plate, and the Antarctic Plate. These plates interact with each other at their boundaries, which can be divergent (moving apart), convergent (moving towards each other), or transform (sliding past each other).

The lithospheric plates move apart at divergent boundaries, collide at convergent boundaries, and slide past each other at transform boundaries. These interactions at the boundaries cause many geological features such as volcanoes, mountain ranges, and earthquakes. The plate tectonics theory has been supported by various lines of evidence, including the study of earthquakes, magnetic anomalies, and the distribution of fossils and rocks around the world.

Answer:

475 J

Explanation:

At the top of the feature, Robert has 475 J of kinetic energy and 2240 J of gravitational potential energy. According to the law of conservation of energy, the total energy of a system is constant, so the sum of the kinetic energy and gravitational potential energy at the top of the feature is equal to the sum of the kinetic energy and gravitational potential energy at the bottom of the feature.

Since Robert is at the bottom of the feature, he has lost all of his gravitational potential energy. Therefore, the total energy he has at the bottom of the feature is equal to his kinetic energy at the top of the feature:

Total energy = Kinetic energy at top = 475 J

Therefore, the answer is 475 J, which is option D.

When a particle is projected at 36 m/s from ground,

a) Time for which it is above a height of 63 m is 2.8s

b) The speed for which it has at this height of 63 m is 7.82 m/s

c) total time of flight is 7.34s.

Velocity is "rate of change of displacement with respect to time".

i.e. v= dx/dt

it is also defined as displacement over time. i.e. v=Displacement/Time.

Velocity shows how much distance can be covered in unit time. It's SI unit m/s.

Acceleration is rate of change of velocity with respect to time.

i.e. a = dv/dt

if an object changes its velocity in short time, we can say that it has grater acceleration.

a= dv/dt =Δv/Δt

Given,

Initial velocity u = 36 m/s

Height of the particle s =  63m

acceleration due to gravity g=9.8 m/s²

a) According to equation of kinematics,

s=ut+1/2gt²

putting all the values in equation,

63=36t+(1/2)(-9.8)t²

multiplying by 2

126=72t-9.8t²

9.8t² -72t +126 = 0  

on solving this quadratic equation, we get

t=4.4s or t=2.8s

(Correct option is t=2.8s)

Hence time to attain 63 m of height is 2.8s

b)According to equation of kinematics,

v²=u²+2as

v² = 36²+2(-9.8)×63 (negative sigh is for velocity and acceleration are oppositely directed)

v² = 61.2

v= 7.82 m/s

Hence Speed at this height is 7.82 m/s

c) Total time of the flight is

at max position of height, final velocity v=0

v= u+at

0=36+(-9.8)t

t= 36/9.8

t = 3.67s .......this is time taken by particle to complete journey from bottom to top,

now it will take same time for particle to come from bottom to top.`

therefore total time taken by particle to go from bottom to top then return back is 2×3.67s

Answer & Explanation:

We can use the following equation to solve the problem:

a = -μk*g

where a is the acceleration, μk is the coefficient of kinetic friction, and g is the acceleration due to gravity (9.8 m/s2).

We are given that a = -9.5 m/s2. We can assume that g is constant and equal to 9.8 m/s2. Therefore, we can rearrange the equation to solve for μk:

μk = -a/g

μk = -(-9.5 m/s2) / 9.8 m/s2

μk = 0.969

Therefore, the coefficient of kinetic friction between the bicycle’s rubber tires and the wet concrete is 0.969.

1. Conjecture: In triangle ABC and A'B'C', all corresponding segments are parallel if the scale factor is greater than or equal to 1.

Let ABC and A'B'C' be two triangles with corresponding sides AB and A'B', BC and B'C', and AC and A'C'. Assume that the scale factor between the two triangles is greater than or equal to 1.

To prove that all corresponding segments are parallel, we need to show that the slopes of these segments are equal.

Consider segment AB and A'B'. Let (x₁, y₁) and (x₂, y₂) be the coordinates of points A and B, and (x₁', y₁') and (x₂', y₂') be the coordinates of points A' and B', respectively. Then, the slope of segment AB is (y₂ - y₁)/(x₂ - x₁), and the slope of segment A'B' is (y₂' - y₁')/(x₂' - x₁').

Since the scale factor is greater than or equal to 1, we have |AB| <= |A'B'|, |BC| <= |B'C'|, and |AC| <= |A'C'|.

Without loss of generality, assume that |AB| <= |A'B'|. Then, we have:

|x₂ - x₁| <= |x₂' - x₁'|, and |y₂ - y₁| <= |y₂' - y₁'|.

Thus, we can conclude that (y₂ - y₁)/(x₂ - x₁) = (y₂' - y₁')/(x₂' - x₁'), which implies that segment AB is parallel to segment A'B'.

Similarly, we can prove that segment BC is parallel to segment B'C' and segment AC is parallel to segment A'C'.

Therefore, we have shown that all corresponding segments are parallel when the scale factor is greater than or equal to 1.

3. If the scale factor is less than one, the proof would need to be modified. In this case, we would have |AB| >= |A'B'|, |BC| >= |B'C'|, and |AC| >= |A'C'|. As a result, we would need to adjust the inequality signs in the proof accordingly. Specifically, we would need to reverse the signs of the inequalities involving the absolute values of the differences between the x and y coordinates of the points in each pair of corresponding segments.

Water exists in three different states, namely solid ice, liquid and gaseous vapour. There are two different formulae, depending upon whether there is a loss or gain of heat, or change of state.

The specific heat capacity is the amount of heat absorbed per unit mass of the substance for a temperature increase of one unit. Its units are given by J/kg K or cal/kg °C. It is useful in calculating the amount of heat lost or gained by a body (Q). The formula for Q is:

Q = m*c*ΔT

where, m is the mass

c is the specific heat capacity and,

ΔT is the change in the temperature of the body

This formula is used to measure the amount of energy required to raise or decrease the temperature of water without a change in its state.

On the other hand, latent heat is the energy released or absorbed when there is a change of state of matter. It is denoted by L. For a change of state, the heat energy Q is given by:

Q = m*L

Note that there is no change in temperature during change of state of matter, and only heat is released or absorbed.

Angular velocity of the drum at this speed having 15m diameter is 3.6 rad/s

Friction is a resistance to motion of the object. for example, when a body slides on horizontal surface in positive x direction, it has friction in negative x direction and that measure of friction is a frictional force.

frictional force is directly proportional to the Normal(N).

i.e. [tex]F_{fri}[/tex]∝ N

[tex]F_{fri}[/tex] = μN

where μ is called as coefficient of the friction. It is a dimensionless quantity.

When a body is kept on horizontal surface, its normal will be straight upward which is reaction of mg. i.e. N=mg.

Given,

Diameter of the drum D = 10m , Radius r = 5m

Coefficient of static friction μ = 0.15

To stay everyone pinned against the wall of drum. Frictional Force must be equal to weight mg which are opposite to each other.

μN = mg ........1)

Centrifugal acceleration = Normal

mv²÷r = N

With this equation 1 becomes

μmv²÷r = mg

v² = rg÷μ

v² = 5m*9.8m/s ÷ 0.15

v² = 326.6

v=  = 18.07 ~ 18 m/s

Hence minimum linear velocity required for the drum  is 18m/s.

for angular velocity of the drum, V=rω

ω = v÷r

ω = 18m/s ÷ 5m

ω = 3.6 rad/s

Hence angular velocity of the drum at 18m/s speed is 3.6 rad/s

The skater's linear momentum has a value of 640 kg/m/s. Kinetic energy of the skater is 5120 J. The skater needs to be subjected to a steady net horizontal force of 160 N in order to come to rest in 4.00 seconds.

The sum of the mass and the instantaneous speed determines the size of the momentum.

The following equations can be used to calculate the skater's linear momentum:

p = mv

p = (40.0 kg)(16.0 m/s) = 640 kg·m/s

As a result, the skater's linear momentum is 640 kg/m/s in magnitude.

B) The skater's kinetic energy is given by:

K = (1/2)mv^2

Substituting the given values, we get:

K = (1/2)(40.0 kg)(16.0 m/s)^2

= 5120 J

Therefore, the skater's kinetic energy is 5120 J.

C) We need to provide a steady net horizontal force that is opposite in direction and of similar size to the skater's starting momentum in order to bring the skater to rest in 4.00 seconds. Applying the average force equation:

F = Δp/Δt

F = (-640 kg·m/s)/(4.00 s) = -160 N
