Yes. That equation is exactly how we write Newton's second law nowadays. Note that the 'x' just means 'times'. It's not another variable. The equation could be written as simply. F = m a .
Answer:
if the mass of both objects is doubled, then the force of gravity between them is quadrupled and so on
Answer:
0.20 A
Explanation:
The current in the wire is given by Ohm's law:

where
I is the current
V is the voltage
R is the resistance
In this problem,
V = 3.0 V is the voltage
is the resistance
Substituting into the formula,

Because the amount of people and the body heat made everything warmer. this may be wrong
