If its accel is constant and not changing from its number then the velocity is changing so True
Answer:
4.6 billion years ago the earth was made of gas and dust that was orbiting the newly forming Sun.
Explanation:
To develop this problem we will apply the considerations made through the concept of Doppler effect. The Doppler effect is the change in the perceived frequency of any wave movement when the emitter, or focus of waves, and the receiver, or observer, move relative to each other. At first the source is moving towards the observer. Than the perceived frequency at first

Where F is the actual frequency and v is the velocity of the ambulance
Now the source is moving away from the observer.

We are also so told the perceived frequency decreases by 11.9%



Equating,





Solving for V,

Answer:
They take the shape of their container.
I think since they move around and fit into anything perfectly.
Your book has applied the chain rule to produce:
dv/dt = dv/dx * dx/dt
Now, we can get dv/dx by:
1) Differentiate
x = vt, with respect to v.
dx/dv = t
Now, if we take the inverse of this, we can obtain dv/dx
dv/dx = 1/t
This is also proven by the fact that dv/dx is the change in velocity and if you multiply it by dv/dx, which is equivalent to dividing by the change in time, as we just proved, then you obtain acceleration.
