Answer:
a)
, with a magnitude of 
b)
, with a magnitude of 
c)
, with a magnitude of 
Explanation:
We have:

We can calculate each component of the acceleration using its definition 

The rate of change of momentum of the ball is 
So for each coordinate:

And these are equal to the components of the net force since F=ma.
If magnitudes is what is asked:

<em>(N and </em>
<em> are the same unit).</em>
False ,it does not only associate with motion of object
4
Just divide 12 by 3, so if it takes 3 seconds, then every second, it goes up 4.
The common value for “Speed of light in vacuum” is
metre per second.
Answer: Option b
<u>Solution:
</u>
Speed of light can be defined as the speed with which light waves propagate in different medium. In vacuum, speed of light is 186,282 miles per second or 299,792 km/s which is rounded off as
.
“Speed of light in vacuum” is a universal constant and usually represented by ‘c’. Light waves travels at a speed of
metre per second in vacuum.
