Answer: This is because water has a higher Specific Heat Capacity than air.
Explanation:
The specific heat capacity of an object measures how much heat will be required to change its temperature.
Water has a higher specific heat capacity than air, so the temperature of the water will remain fairly constant even though the air surrounding the water is experience temperature changes.
Since air has a lower Specific Heat Capacity than water, heat from the sun will readily heat it up in comparison to water.
Answer:
<h3>B - Isaac Newton</h3>
Explanation:
He first thought of his system of gravitation which he hit upon by observing an apple fall from a tree,
The incident occurring in the late summer of 1666.
Answer:
The heat gain of the room due to higher efficiency is 2.84 kW.
Explanation:
Given that,
Output power of shaft = 75 hp
Efficiency = 91%
High efficiency = 95.4%
We need to calculate the electric input given to motor
Using formula of efficiency
We need to calculate the electric input
For, heigh efficiency
The reduction of the heat gain of the room due to higher efficiency is
Put the value into the formula
Hence, The heat gain of the room due to higher efficiency is 2.84 kW.
A) F = gravitational force
b) G = universal gravitational constant (6.67 × 10-11 N-m2/kg2)
c) m1 = mass of the body 1
d) m2 = mass of body 2
e) r = radius or distance between the two bodies.
Hope this helps!
