Answer:
2m/s²
Explanation:
Given parameters:
Net force on the car = 2000N
Acceleration = 4m/s²
Unknown:
Acceleration of a car twice the mass = ?
Solution:
Let us first find the mass of the car;
Force = mass x acceleration
Mass = 
Mass = 
= 500kg
Now,
whose mass is twice that of the car
Mass of the new car = 2 x 500 = 1000kg
So;
Acceleration = 
Acceleration = 
= 2m/s²
Answer:
a force that attracts matter to the earth
Explanation:
depends on where you are the gravity can be different in space there is no gravity on Earth there is , that's why when you jump you come back down
The difference in electric potential energy between the two points is
where q is the magnitude of the charge and
is the electric potential difference.
But for energy conservation, the difference in electric potential energy
between the two points is equal to the work done to move the charge between A and B:
so we have
and by substituting the numbers of the problem, we find the value of
:
Energy stored in a capacitor is Electric Potential Energy. Capacitor is device used for storing energy. The work done to charge is a capacitor is stored in it in the form of Electrical potential energy. Electrical potential energy is defined as capacity to do work due to the position change. For example, we know fans have capacitor installed in it. When we turn off the fan, it continue moving using the electrical energy stored in the capacitor.
The one tossed upward on the Moon will rise to a greater maximum height before starting to fall.
It'll also spend more total time in flight before returning to the hand that tossed it. (I almost said that it'll spend "more time in the air". That would be silly on the Moon.)
