If the speed of the particle is doubled. Then the value of the momentum also gets doubled.

<h3>What is momentum?</h3>

The sum of an entity's speed and mass is known as its linear momentum, translational momentum, or simply momentum in Newton's laws of motion. It has both a magnitude and a direction, making it a vector quantity. The SI unit of momentum is kg-m / s.

Let m be the mass and v be the velocity of an object. Then the momentum is given as,

P = mv   kg-m / s

A particle is moving at a speed less than c / 2. If the speed of the particle is doubled.

P = m(2v)

P = 2mv

If the particle's speed is twice. The momentum's value is then increased by two.

More about the momentum link is given below.

Alecsey [184]

Answer:

I believe it's 2) sound waves

Explanation:

With sound waves, the energy travels along in the same direction as the particles vibrate. This type of wave is known as a longitudinal wave, so named because the energy travels along the direction of vibration of the particles.

A bullet is shot vertically upward with an initial velocity of 128 ft/s. The bullet's height after t seconds is y(t) = 128t - 16
saul85 [17]

The height of the bullet when the velocity is zero is 256 ft.

<h3>Height of the bullet when the velocity is zero </h3>

The height of the bullet when the velocity is zero is determined by taking derivative of the function as shown below;

v = \frac{dy}{dt} = 128 -32t \\\\when \ v \ is \ zero\\\\v = 0\\\\128 - 32t = 0\\\\32t = 128\\\\t = \frac{128}{32} \\\\t = 4 \  s

The height of the bullet at this time is calculated as follows;

y(4) = 128(4) - 16(4)^2\\\\y(4) = 256 \ ft

What should be done to lift the same load by applying less effort on an inclined plane​
Scorpion4ik [409]

Answer:

Reduce the friction at the surface

Explanation:

If you can reduce the friction between the load and the plane less effort will be required as you are not having to apply effort to overcome friction.
