Answer:

Acceleration is the rate of change in velocity. Momentum is the mass times the velocity. So if you multiply the mass times the acceleration, you get the of change of momentum.

One student did an experiment on the rock cycle.

Nonamiya [84]

First, when the student added the layers of wax over each other, this became a representation of sedimentary rocks.

Then the student folded his/her palm and squeezed the layers of wax. This means that the student applied heat and pressure on the wax (sedimentary rocks)

Referring to the diagram below which represents the rock cycle, we will find that applying heat and pressure on sedimentary rocks would convert these rocks into metamorphic rocks.

Based on the above, the best choice would be:
d. Heat and pressure can change sedimentary rocks into metamorphic rocks.

A car sitting at a red light begins to accelerate at 2 m/s2 when the light turns green. It continues with this acceleration unti

jek_recluse [69]

Answer:

x_total = 600 m

Explanation:

This is an exercise and kinematics, let's find the time it takes to reach the velocity 20 m / s

v = v₀ + a t

as part of rest v₀ = 0

t = v / a

t = 20/2

t = 10 s

let's find the distance traveled in this time

x₁ = vo t + ½ a t2

x₁ = 0 + ½ 2 10²

x₁ = 100 m

The remaining time is

t₂ = 35 - t

t₂ = 35 - 10

t₂ = 25 s

as in this range it has a constant speed

v = x₂ / t₂

x₂ = v t₂

x₂ = 20 25

x₂ = 500 m

the total distance traveled is

x_total = x₁ + x₂

x_total = 100 + 500

x_total = 600 m

Kepler's First Law states that the shape of planetary orbits is a/an ________________ ?

harkovskaia [24]

Answer:

elliptical orbit

Explanation:

There are three laws of planetary motion, which are called Kepler's law of planetary motion.

First Law : It states that all the planets revolve around the sun in an elliptical path and the sun is at one focus of that elliptical path.

The process of arriving at a general conclusion based on the observation of specific examples is called ___________ reasoning.

olga55 [171]

The process of arriving at a general conclusion based on the observation of specific examples is called inductive reasoning. It is a logical process where multiple premises are combined to obtain a conclusion. It is used in applications that involve prediction and forecasting.
