the unit for volt is v
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force.
Explanation:
d) Magnetic force is the power that pulls materials together (magnet e. g iron)
an example :how magnet can pick up a coin.
e) frictional force produces when two surfaces are in contact with each other.
effects of friction : I) it produces heat
II) it causes loss in power.
Answer:
294.3 N
Explanation:
In this situation, we are told that the crate is not accelerating in the horizontal plane. But also it is not accelerating in the vertical plane. Meaning that the sum of all vertical forces add up to zero.
Fnet = ma
Weight + Normal force = mass * acceleration
-(30 kg * 9.81 m/s²) + Normal force = 30.0 kg * 0 m/s²
Normal force = 294.3 N
water does form a hydrogen but oil on the other hand does not
