A LOT OF POINTS!! Best answer gets brainliest!

1) Which two of the following factors affect the momentum of an object: speed, velocity, mass, shape?

2) Can a small object can have a large momentum? Give an example.

3) How could you change the momentum of an object? What would you need to change?

4) A 5000kg truck and a 50 kg person have the same momentum. How is this possible?

Answers

Answer 1

1. velocity and mass
2. Yes if the small object has a high velocity (like if a paper airplain was going super fast)
3. You would have to change the velocity cause you can’t change it’s mass
4. The person would have a higher velocity

Which of the following remains constant during the motion of a projectile fired from a planet?

A. Momentum

B. Kinetic energy

C. Horizontal component of velocity

D. Vertical component of velocity

Answers

Answer:

C. Horizontal component of velocity

Explanation:

Object in motion stays in motion,

nothing works against its motion in the horizontal direction, unlike in the vertical direction, gravity pulls object down.

Which of the following has the most momentum? proton (m=1.67 x 10-27 kg) moving at 2.0 x 104 m/s,an electron (m=9.11 x 10-31 kg) moving at 2.0 x 106 m/s, a common house fly (m=12 mg) moving at 2.0 m/s, North American tectonic plate (m≈5x1022 kg) moving at 3.0x10-10 m/s (about 1cm/yr)

Answers

Answer:

The North American tectonic plate.

Explanation:

recall the formula for momentum: p = m * v

the subatomic particles have very small masses while high speeds, so the product results in values with negative exponents in scientific notation.

Negative exponents also result for the house fly when converting mg into kg (10^-6).

The positive exponents in scientific notation for the momentum come for the gigantic mass of the continental plate which exceeds the negative exponents contributed by the small velocity.

(6.MS-ETS2-1(MA).) The electrons in __________ move about more freely than the electrons in insulators which is why this type of material can be used to create electric circuits.

A) conductors
B) insulators
C) magnets

Answers

Answer:

A) conductors

Explanation:

A conductor can be defined as any material or object that allows the free flow of current or electrons (charge) in one or more directions in an electrical circuit. Some examples of a conductor are metals, tungsten, copper, aluminum, iron, graphite, etc.

Basically, the main purpose of a conductor in physics is to provide a low-resistance path between electrical circuits or components. This low-resistance path is to ensure that the electrical components allows the free flow of electrons and thus, enabling charge transfer.

Hence, the electrons in conductors move about more freely than the electrons in insulators which is why this type of material can be used to create electric circuits because it would significantly provide a low-resistance path between the electric circuits.
