Value of resistor = (12V) /(1.2 x 10^-3A)=10000ohms=10k ohms
Answer:
Assume that the ball undergoes motion along a straight line. ... F = m A Force = (mass) x (acceleration) The question tells you the mass and the acceleration. All YOU have to do is take the numbers and pluggum into Newton's 2nd law. F = m A = (0.75 kg) (25 m/s²) = (0.75 x 25) kg-m/s² = 18.75 Newtons .
Explanation:
i looked it up ok
Answer:
option c is correct
Explanation:
we know that time rate of change of velocity is called acceleration
so a=v/t
a=12/4
a=3m/s²
<span>Like electric charges repel each other. TRUE
I hope this helped :)</span>
