</span>If the ramp has a length of 10 and has a
mechanical advantage (MA) of 5. Then we need to find the height of the ramp.
Formula:
MA = L / H
Since we already have the mechanical advantage and length, this time we need to
find the height .
MA 5 = 10 / h
h = 10 / 5
h = 2 meters
Therefore, the ramp has a length of 10 meters, a height of 2 meters with a
mechanical advantage of 5.</span>
The scale reading increases by the weight of 200 g of mass. (If you're on Earth, that's about 2 Newtons.)
The distribution of earthquake
across the globe provides the primary indicator of boundaries between all
tectonic plates. Earthquakes have a definite distribution pattern. There are
three major belts in the world which are frequented by earthquakes of varying
intensities and these belts are as under the circus pacific belt, mid Atlantic
belt and mid continental belt.
Answer : The rate of heat transfer to the water is, 37.92 kJ/min
Explanation : Given,
Time = 10 min
Mass of water = 200 g
Latent heat of fusion of water = 334 J/g
Latent heat of vaporization of water = 2230 J/g
Now we have to calculate the rate of heat transfer to the water.
Now put all the given values in the above formula, we get:
Thus, the rate of heat transfer to the water is, 37.92 kJ/min
