Answer:
d. Imaginary point through which the resultant force of gravity acts on an object
Explanation:
Gravity acting on all particle points of the object, no matter how small they are. As a combination, the center of gravity would denote a single point which substitutes for all the gravity forces on the object.
Answer:
True.
Explanation:
During the late summers the SST (sea surface temperature) rises the most which made the wind above the sea moist and warm. Global warming is also one of the cause of the rise in sea surface temperatures. Then the Coriolis effect due to the earth's rotation make these winds to rotate which results in the formation of the cyclones mostly in the areas near to equator.
K=1/2 mv2
M=?
41.6kj convert to joules by multiplying by 1000 so it will be 41,600J because the unit of kinetic energy is in joules.
41,600=1/2(m)(8)
Arrange the equation it will be:
M= 41,600/4 = 10,400
Final answer is:
m= 10,400 kg
Venus is the hottest world in the solar system. Although Venus is not the planet closest to the sun, its dense atmosphere traps heat in a runaway version of the greenhouse effect that warms Earth.
Magnets are different because the molecules in magnets are arranged so that their electrons spin in the same direction.
