A 1,116 kg space vehicle is traveling along a straight-line at a constant speed of 800 m/s. What is the magnitude of the net force on the space vehicle?

Answers

The magnitude of the net force on this space vehicle moving at constant speed is zero (0) Newton.

What is a net force?

A net force can be defined as the vector sum of all the forces that are acting on a physical object or body. This ultimately implies that, a net force is a single force that substitutes the effect of all the forces acting on a physical object or body.

Generally speaking, the amount of net force that keeps a physical object or body moving at constant speed and in the same direction is always equal to zero (0) Newton in accordance with Newton's First Law of Motion.

In this context, we can reasonably infer and logically deduce that the net force on a physical object or body would be equal to zero (0) Newton when it moves at constant speed.

Answers

Temperature is a unit used to represent how hot or cold something is. It can be stated using the Celsius or Fahrenheit scales, among others. Temperature shows which way heat energy will naturally flow, i.e., from a hotter (body with a higher temperature) to a colder (body with a lower temperature) (one at a lower temperature)

Additionally, we are provided the iron's particular heat as well as the iron skillet's mask.

We must determine the required quantity of heat based on this information. It will be Q = c x mass x delta P using this method.

That is the temperature change. Therefore, we can replace the value here. The c represents the iron's particular temperature. That comes to 0.4499.

The supplied mass is 5.07, and the resulting temperature change will be 250 - 25 °C. If we can solve this, we can determine what Q is worth.

a) A ball falls toward the ground:
The force of gravity is acting on the falling ball. On the surface of the earth, the direction of this force is always downward, towards the ground. It pulls on all objects with mass.

b)A person accelerates up in an elevator:
On the person in the elevator, there are two forces:
1) Normal Force upward, exerted by the floor on the person perpendicular to the surface (“normal” means perpendicular).
2) Gravitational Force downward, exerted by the Earth on the person. This is also called the person’s “weight”.

c) A car gradually slows down while approaching a red light.:
Friction may slow the car down as it moves along the road, but it also is the force that enables the car to move forward at all. It is the friction force that keeps the tires from sliding on the road. By the same token, it is friction that makes the car come to a stop when the brakes are applied.


What is Force ?
An object's push or pull is seen as exerting a force. The interaction of the objects produces push and pull. You can also use words like stretch and squeeze to describe force. The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude. The application of force is the location at which force is applied, and the direction in which the force is applied is known as the direction of the force. A spring balance can be used to calculate the Force. Newton is the SI unit of force (N).

Consider two homogeneous bodies of the same volume is it necessary for them to have same mass why

Answers

No, two homogeneous bodies of the same volume do have not the same mass.

How do two bodies of the same volume have the different same mass?

No, two objects don't need to have same volume to have the same mass because the density of the objects they are made up of can be different from one another. Mass and volume are independent, two objects with the same volume can have different amounts of masses. So that's why the objects can have different densities. Density is defined as the mass of the substance divided by its volume.

Density = mass /volume

Mass is defined as the amount of matter that is present in an object, while on the other hand, volume is the space occupied by an object. For example, a bowling ball and a basketball have the same volume but the bowling ball has more mass.

So we can conclude that two homogeneous bodies of the same volume do have not the same mass because of the difference in their volume.

A puck of mass m = 0.065 kg is moving in a circle on a horizontal frictionless surface. It is held in its path by a massless string of length L = 0.65 m. The puck makes one revolution every t = 0.55 s. what is the magnitude of the tension in the string while the pack is revolving?if the string breaks how fast will the pack move away?

Answers

The centripetal acceleration of an object in circular motion with tangential velocity v if the radius of the trajectory is r, is:

[tex]a_c=\frac{v^2}{r}[/tex]

On the other hand, if the period of one revolution is T, then the distance traveled is 2πr (which is the circumference of the trajectory) and the tangential velocity is:

[tex]v=\frac{2\pi r}{T}[/tex]

In this case, the radius of the trajectory is the length of the string, 0.65m, and the period is T=0.55s. Substitute these data into the formula to find v:

[tex]v=\frac{2\pi(0.65m)}{0.55s}=7.4256\frac{m}{s}[/tex]

Plug in v=7.4256m/s and r=0.65m to find the centripetal acceleration of the puck:

[tex]a_c=\frac{(7.4256\frac{m}{s})^2}{0.65m}=84.83\frac{m}{s^2}[/tex]

According to Newton's Second Law of Motion, there must be a net force acting on the object responsible for the centripetal acceleration. That force F is the tension of the string. Then:

[tex]F=m\cdot a_c[/tex]

Substitute the value for a and m=0.065kg to find the tension of the string:

[tex]\begin{gathered} F=0.065\operatorname{kg}\times84.83\frac{m}{s^2} \\ =5.51N \end{gathered}[/tex]

If the string breaks, the puck will move as fast as its tangential velocity, which is 7.4 m/s.

Also, w = 2πf

Therefore, 2πf = 24π

f = 24π/2π

f = 12 Hz

The frequency = 12 Hz

Is nuclear energy apart of physics ?

Answers

Nuclear energy:

It basically originates from the splitting of uranium atoms. This is basically done by the process of fission. It is the energy that is released in significant amounts in processes that affect atomic nuclei, the dense cores of atoms

A storage tank 20 m high is filled with pure water. (Assume the tank is open and exposed to the atmosphere at the top.)
(a) Find the gauge pressure at the bottom of the tank.


(b) Calculate the magnitude of the net force that acts on a square access hatch at the bottom of the tank that measures 0.6 m by 0.6 m.


PLEASE HELP ASAP!!!

Answers

A. The overpressure at the bottom of the tank is 297500 N/m².

B. The magnitude of the net force acting on the square access hatch at the bottom of the tank is 107100 N.

Multiplying the flow rate by the minimum operating time of the pump gives the descending capacity. As a rule of thumb for a minimum run time, a pump operating at 10 gallons per minute GPM or less should produce a run time of 1 gallon per minute. For example, 10 GPM flow rate x 1 = 10 gallon drawdown capacity.

This means that the gauge pressure is equal to the absolute pressure minus the atmospheric ambient pressure. If the absolute pressure is greater than the atmospheric pressure it is called positive overpressure. If the absolute pressure is lower than atmospheric pressure it is called negative overpressure. The hydrostatic pressure at any height below water is calculated by P = hdg. where h is the height below open water.

Relate scientific theories to the law of parsimony

Answers

In science, the law of parsimony is used to select between related scientific theories to those that contain a minor number of assumptions.

What is the law of parsimony?

The law of parsimony is a well-sustained body of information that shows how the theories that contain a minor number of assumptions before experimentation are generally the correct ones.

Therefore, with this information, we can conclude that the law of parsimony can be used to select scientific theories and this approach is generally accurate to obtain the correct theory to be used due to assumptions that may hamper the scientific results.
