Answer:
6J
Explanation:
Given parameters:
Mass of fish = 1kg
Velocity = 12m/s
Unknown:
Change in kinetic energy = ?
Solution:
Kinetic energy is the energy due to the motion of a body. It is mathematically given as:
K.E = m v²
Now, insert the parameters and solve;
K.E = x 1 x 12 = 6J
The change in kinetic energy is 6J
You're going to have to give me the choices.
I'm pretty sketchy on that subject.
Answer: A current of 1 A is flowing in a circuit if a charge of 1 coulomb passes any point in the circuit every second.
1 Amp = 1 Coulomb per second
We can write this formula as:
Current (I) = Charge (Q) / Time (t)
Charge (Q) = Current (I) x Time (t)
Explanation:
Answer:
Direction is downwards
Explanation:
This is by employing Flemings Right hand rule which says If you point your pointer finger in the direction the positive charge is moving, and then your middle finger in the direction of the magnetic field, your thumb points in the direction of the magnetic force pushing on the moving charge.
