Here is the highly detailed, arcane, complex, technical form of Ohm's Law that is needed in order to answer this question ===> V = I · R .
Voltage = (current) x (resistance)
Voltage = (2 Ampere) x (8 Ω)
<em>Voltage = 16 volts</em>
Answer:
18.82 m
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 20 m/s
Horizontal distance (s) = 39.2 m
Height (h) of the cliff =?
Next, we shall determine the time taken for the car to get to the ground. This can be obtained as follow:
Initial velocity (u) = 20 m/s
Horizontal distance (s) = 39.2 m
Time (t) taken to reach the ground =?
s = ut
39.2 = 20 × t
Divide both side by 20
t = 39.2 / 20
t = 1.96 s
Finally, we shall determine the height of the cliff as follow:
Acceleration due to gravity (g) = 9.8 m/s²
Time (t) taken to reach the ground = 1.96 s
Height (h) of the cliff =?
h = ½gt²
h = ½ × 9.8 × 1.96²
h = 4.9 × 3.8416
h = 18.82 m
Therefore, the cliff is 18.82 m high
Answer:
In thermodynamics, heat is transferred energy that moves between substances or systems because of their temperature difference. According to the first law of thermodynamic and the law of energy conversion s a form of energy, heat is cannot be created or destroyed only moves from one form to other.
The stone gets heat energy from fire and moves this heat energy or thermal energy to water as it cools off and the water warms up. Heat moves or is transferred spontaneously from the hot stone into the cold water. Eventually, the stone and water have the same temperature and water becomes heated. At the time of heat flowing out of the stone into the water, the heat energy became less ordered, due to spreading out through both the stone and the water. This is a net increase in entropy which is the second law of entropy.
