How could you increase the kinetic energy of a truck without increasing its velocity?

Answers

Answer 1
Answer: Kinetic energy consists of 2 elements, mass and speed. If its velocity, that is speed, remains the same, you have to increase the mass to increase its kinetic energy without affecting velocity.
Answer 2
Answer: Kinetic energy of something depends on its mass and speed. 
So if you want to keep the same speed but increase its kinetic
energy, then the simple answer is that you have to increase the mass.

But it's not as simple as that.

If there's a truck cruising along the highway, and you want to increase
its kinetic energy without changing the speed, then it's true ... you'll
have to increase the mass.  You might have a helicopter swoop in low
over the truck and drop some bales of hay onto it.  That will certainly
increase the mass. But that DOESN't magically increase the kinetic
energy.  More energy has to COME from somewhere.

When the bales hit the bed of the truck and the mass suddenly increases,
if the driver doesn't want his speed to drop, he has to mash the gas pedal
a little farther, run the engine a little faster, and let the engine deliver more
energy.  THAT's where the extra kinetic energy comes from ... extracting
more chemical energy out of more gasoline.

2. A 2kg body attached to a spring undergoes a SHM of amplitude 0.4m and period0.Sts. a) What maximum force acts on a body? b) Find the acceleration of the body
at a distance of 0.2m for m the equilibrium position.​

Answers

Answer:

a) 12.8 N

b) 3.2 m/s²

Explanation:

I'm guessing the period is 0.5π s.

Period of a spring in simple harmonic motion is:

T = 2π √(m/k)

Given T = 0.5π and m = 2 kg:

0.5π = 2π √(2/k)

0.25 = √(2/k)

0.0625 = 2/k

k = 32

The spring constant is 32 N/m, and the maximum displacement is 0.4 m.  The maximum force can be found with Hooke's law:

F = kx

F = (32 N/m) (0.4 m)

F = 12.8 N

The acceleration can be found with Newton's second law:

∑F = ma

kx = ma

(32 N/m) (0.2 m) = (2 kg) a

a = 3.2 m/s²

Could someone please explain what makes up the electromagnetic spectrum? Thank you.

Answers

These types include gamma rays, x-rays, ultraviolet, infrared, microwaves and radio waves. Together with visible light, all these types of radiation make up what we call the electromagnetic spectrum - the complete spectrum of radiation.
Radio waves, microwaves, infrared waves, visible light, ultraviolet, x-rays, and gamma rays.

-Waves can travel through a vaccum
-These waves radiate in all directions
-travel through speed of light
-they are transverse waves
-they are made by interaction between an rlectric and a magnetic field.

These are the main points. I hope this will help you! ❤️.

Which has more inertia a shopping cart full of groceries or an empty shopping cart

Answers

Ok, so you would want to define inertia before trying to answer the question. Inertia is basically the force of resistance on an object, or any change to its speed, because of natural factors, like friction or gravity. The shopping carts decribed above, based upon the definition of inertia, the shopping cart full of groceries would have more inertia.

Final answer:

Inertia is a property of an object that resists changes in motion, and its quantity is directly proportional to the object's mass. Therefore, a shopping cart full of groceries, having a greater mass, will exhibit more inertia than an empty shopping cart.

Explanation:

In physics, inertia refers to the tendency of an object to resist changes in its motion. The greater an object's mass, the greater its inertia, making it harder to start or stop its movement. In comparing a shopping cart full of groceries and an empty one, the cart full of groceries will have a higher mass, thus a greater inertia.

Consider an experiment where you exert the same amount of force on both carts. The full cart would be more resistant to change in motion and would move slower or a shorter distance than the empty one due to the higher inertia it possesses.

The same principle can be applied to a group of students using two carts (A and B) for a one-dimensional collision experiment. Cart B with unknown mass is initially at rest while cart A with known mass moves towards it. Since mass directly influences inertia, if cart B was loaded with materials (like a shopping cart full of groceries), it would be harder to shift its motion than if it were empty.

Is orange juice in an orange potential energy or kinetic energy?

Answers

Answer:

Potential energy.

Explanation:

The potential energy is the energy which is possessed by the body by the virtue of its position with respect to the others, electric charges and with other factors.

And the kinetic energy is defined as the energy of an object which is produced by the virtue of the motion of an object.

Therefore, in the given situation orange juice does not possess any velocity it is in rest. So orange juice is an orange potential energy.

It would be potential energy because it is not moving.
