As we know that when charge is released in electric field
It will have two forces on it
1. electrostatic force
2. gravitational force
now if the ball will accelerate upwards so we can say
net upward force = mass * acceleration
now we can find charge q on it by above equation
So above is the charge on the particle
Answer: As the temperature of the water decreases from 20 degrees celsius to 4 degrees celsius, the density increases.
Explanation:
Answer:
a is a good answer
Explanation:
because most items whether clothes or things we eat with, are made with something natural and recycled
Answer:
615 J
Explanation:
internal energy (U) = 504 J
heat lost (q) = 111 J = - 111 J (negative sign is because heat is lost)
work done = 222 J
what is the final energy in the system
total energy = final energy - initial energy
final energy = total energy + initial energy
where
initial energy = 504 J
total energy = 222 - 111 = 111 J
final energy = 504 + 111 = 615 J
