Acceleration =
(change in speed) / (time for the change)
and the direction of the change.
Acceleration = (60 - 0) km per hour / 5 sec = <em>12 km per hour per second, east</em>.
I hear teachers all over the country complaining about that ugly unit.
It has to be changed to a more familiar unit of acceleration.
(12 km/hour) x (1 hour/3600sec) = 12,000/3600 = 3-1/3 meter/sec.
His acceleration is <em>3-1/3 meters per second²</em> .
The overall force of gravity becomes stronger and stronger. This is because the gravity depends on the inverse of the square of the distance:
and since the distance r between the molecules becomes smaller, the gravity increases more and more.
Answer:
The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

Answer:
Explanation:
The acceleration of the motorcycle is given by
where
v=24 m/s is the final velocity of the motorcycle
u=15 m/s is the initial velocity
t=3 s is the time taken
Substituting these numbers into the equation, we find
energy is the correct answer to fill the blank bb :)
