Answer:
a) Her feet are in the air for 0.73+0.41 = 1.14 seconds
b) Her highest height above the board is 0.82 m
c) Her velocity when her feet hit the water is 7.16 m/s
Explanation:
t = Time taken
u = Initial velocity = 4 m/s
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
b) Her highest height above the board is 0.82 m
Total height she would fall is 0.82+1.8 = 2.62 m
a) Her feet are in the air for 0.73+0.41 = 1.14 seconds
c) Her velocity when her feet hit the water is 7.16 m/s
The answer would be D, negative acceleration
When warm air layer traps pollution that is within the earth's surface, a temperature inversion usually takes place. In addition, at temperature inversion happens when the cold air overlays the warm air in the troposphere, which does not usually happen since warm air rises and cold air sinks by principle.
Answer:
Velocity, quantity that designates how fast and in what direction a point is moving.
Explanation:
Answer:
Igneous rock , formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth's surface. Metamorphic rocks, formed by temperature and pressure changes inside the Earth.
