Gravity can cause water to move down and carry sediment and rocks along the bottom. if the water slows down, it drops the rocks and if it floods a field then the grass will also filter smaller particles out leaving fine sediment behind. In addition to it the fast flow of water can cause erosion, over time it can cause valleys as well.
Answer:
it lowers the voltage in homes
Explanation:
this is due to safety reasons as a human cant survive power line voltages which are between 150k and 760k and if you plugged anything short of a piece of 1 inch thick wire not counting insulation it would immediately start smoking and burn the cable.
Answer:
The time taken to complete her run is 1.9 hr.
Explanation:
Speed is a scalar quantity and it is defined as the ratio of distance covered to the time taken to cover that distance. As distance is also a scalar quantity, so the directions given in the problem can be ignored. Thus, the distance covered by the jogger is the sum of kilometers given in problem.
Distance covered = 6+5+4 = 15 km
And the speed is given as 8 km/hr.
So the time taken will be ratio of distance to speed.
So the jogger will take 1.9 hr to complete her run.
Answer:
An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel. In California there are two plates - the Pacific Plate and the North American Plate
Explanation:
just write it in ur own words
Answer:
the gasoline releases Q=-4138387 J/mile to the atmosphere
Explanation:
from the fist law of thermodynamics
ΔU = Q - W
where ΔU= change in internal energy , Q= heat received , W= work done by the system
then
Q = ΔU + W
knowing that
ΔU = internal energy per gallon * number of gallons consumed in 24.8 miles
= (-1.19 x 10^8 J/ gallon) * 1 gallon /24.8 miles = (-4798387 J/mile)
W = work done by mile= 6.60 x 10^5 J/mile
therefore the heat released per mile
Q = ΔU + W = -4798387 J/mile + 6.60 x 10^5 J/mile = -4138387 J
since Q is negative , energy is released into the atmosphere
