The cat has a speed. The truck and the bicycle both have velocity. We can't be sure of what the plane has.
Atom absorbs energy when it goes into higher orbitals from their "Ground States"
Hope this helps!
Answer:
Geosphere
Explanation:
The Geosphere is the solid Earth,composed principally of rock (by which we mean any naturally formed, nonliving, firm coherent aggregate mass of solid matter that constitutes part of a planet).
The geosphere is defined to be that component of the Earth system involving the inside of the Earth, rocks and materials, minerals, land forms and the mechanisms that shape the surface of the Earth. Contrary to Christopher Columbus, the Earth is not in itself a perfect sphere.
Answer: 
Explanation:
This problem can be solved by the following equation:
Where:
is the change in kinetic energy
is the electric potential difference
is the electric charge
Finding :
Finally:
Answer:
7.5s
Explanation:
Given parameters:
Velocity = 30m/s
Deceleration = 4m/s²
Unknown:
Time it takes for the car to come to complete rest = ?
Solution:
To solve this problem, we use the kinematics expression below:
v = u + at
Since this is a deceleration
v = u - at
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken
v - u = -at
0 - 30 = -4 x t
-30 = -4t
t = 7.5s
