Given parameters:
Initial velocity(body is at rest) = 0m/s
Final velocity = 8m/s
Time of acceleration = 2s
Unknown:
Acceleration of the dog = ?
Acceleration is defined as the change in velocity with time.
Mathematically;
Acceleration = 
Now input the given parameters and solve;
Acceleration = 
Acceleration = 4m/s²
The dog is accelerating at a rate of 4m/s²
Answer:
Option A
Explanation:
The statement makes sense since it's already explained that the galaxy is moving away from us and unlike option C which depicts that the galaxy is moving to us.
This statement makes sense. The redshift means that we see the galaxy moving away from us, so observers in that galaxy must also see us moving away from them—which means they see us redshifted as well
Explanation:
Given
mass (m) = 2 kg
acceleration due to gravity (g) = 10 m/s²
Force (F) = ?
We know
F = m * a
= 2 * 10
= 20 N
The force is 20 N.
Hope it will help :)❤
