Hey user
The energy E in joules (J) is equal to the voltage V in volts (V), times the electrical charge Q in coulombs (C):
E(J) = V(V) ×<span> Q</span>(C)
So
joule = volt × coulomb
or
J = V × C
Example
What is the energy in joules that is consumed in an electrical circuit with voltage supply of 15V and charge flow of 4 coulombs?
E = 15V × 4C = 60J
2 oxygen atoms are used to bond with sulfer
Answer:
5m
Explanation:
because if the driver jamed the brakes at 20m and stop at 15m the it took the driver 5m to fully stop
Answer:
The velocity of Dan is 1.13 m/s.
Explanation:
Given that,
Initial velocity of skateboard and Dan = 2.00 m/s
Velocity of skateboard = 7.00 m/s
Mass of Dan m= 40.0 kg
Mass of skateboard M= 7.00 Kg
Suppose How fast is Dan going as his feet hit the ground?
We need to calculate the initial velocity of Dan
Using conservation of momentum

Put the value into the formula



Hence, The velocity of Dan is 1.13 m/s.
