differences in pressure
B)
differences in temperature
C)
Earth's revolution round the Sun
D)
the Moon's revolution round Earth
Answer:
Correct Answer is B (Differences in temperature)
Explanation:
One of the main cause of ocean current to occur is variation of temperature of different layer of oceanic water.Water which have high temprature is less dense and this Less density water float above the surface of high density water. When this less density water reached on the surface of ocean that time wind which blows on the surface water makes the water cool or in other words we can say that water released its heat to the surrounding environment. when water becomes cool it again shifted in downward direction and less density water will moves upward. In this way this process will continue and hence ocean current is created.
astronomers named the planet Kepler-186f
Astronomers named the planet they discovered Kepler-186f after the Kepler space telescope, which took the first picture of the planet.
kg are units of mass. The acceleration on the moon due to gravity is roughtly 1/6 that of earth. A more precise figure is 1.62 m/s^2
a = 1.62 m/s^2
m = 83 kg
F = ?
F = m * a
F = 83 * 1.62
F = 134.46 Moon's gravitational force on 83 kg man
On earth the force would be 83 * 9.81 = 814.23 Newtons.
the man would only weigh 13.7 kg on the moon

Power in physics is the rate of energy transferred per unit time. It can be calculated by dividing the amount of energy transferred by the time required for the transfer.
In Physics, power is defined as the rate of transferring energy or the amount of energy per unit time. If you want to calculate the power, you take the amount of energy transferred and divide it by the time it takes for that transfer to occur. For example, if a light bulb transfers 100 joules of energy over 10 seconds, the power would be 100 joules divided by 10 seconds, which equals to 10 watts.
