Answer:
The answer is Watt
Explanation:
Electricity is measured in Watts and kilowatts
Electricity is measured in units of power called Watts, named to honor James Watt, the inventor of the steam engine. A Watt is the unit of electrical power equal to one ampere under the pressure of one volt. One Watt is a small amount of power.
Answer:
Low-pressure zone
High-pressure zone
Explanation:
When the surface of the earth is heated due to the heat energy radiated from the sun, the air mass near the earth's surface also gets heated up, as a result of which it becomes warm and less dense and eventually rises up. This warm air when rises upwards, forms a low-pressure zone, which subsequently results in the occurrence of rainfall. Here, the atmospheric pressure remains lower than that of nearby areas.
Again, When the warm air rises up, it experiences lower temperatures and cools down. As it cools, it again becomes dense and thereby falls back, forming a high-pressure zone, where the atmospheric pressure remains relatively higher than the surrounding places.
Answer:
<h2>1340 J</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 67 × 20
We have the final answer as
<h3>1340 J</h3>

Answer:
r = 4.24x10⁴ km.
Explanation:
To find the radius of such an orbit we need to use Kepler's third law:
<em>where T₁: is the orbital period of the geosynchronous Earth satellite = 1 d, T₂: is the orbital period of the moon = 0.07481 y, r₁: is the radius of such an orbit and r₂: is the orbital radius of the moon = 3.84x10⁵ km. </em>
From equation (1), r₁ is:
Therefore, the radius of such an orbit is 4.24x10⁴ km.
