1850 to 1900 because the slope would be 105. It says what is the greatest fall, so the upward slope of 120 wouldn't count.
Answer:
option A
Explanation:
given,
depth of the sea level = 10 m
g = 10 m/s²
Pressure underwater = ?
we know,
P = ρ g h
where ρ is the density of water which is equal to 1000 kg/m³
h is the depth of sea level
P = ρ g h
P = 1000 x 10 x 10
P = 100000 Pa
P = 100 kPa
Hence, the correct answer is option A
Since the law of gravitation is an inverse square law if you
quadruple the radius the f will drop by a factor of 16 SO the object would
weigh 200/16 = 12.5N
In other words, as the distance, or radius, quadruples the
weight becomes 1/16 of the original weight. Just plug in 4 for r and when you
square it you get 16. The numerator is 1 so that is how the weight becomes
1/16.

Answer:
There is no heat transfer in the system as the temperature before and after remains same i.e, 25 C.
Explanation:
Heat energy is mathematically expressed as,
Q=mCΔT
By looking at the above equation we can say that heat gain or loss by any system is equal to the mass times specific heat multiplied by the change in temperature.
Now if we consider the water system in view of this equation then ΔT would be 0 therefore it is evident that there is no transfer of heat.
If we consider the empty half of the tank so it is mentioned that there is nothing no air and giving us m=0, hence Q=0.
Mathematically we can express this as
Q=mCΔT
Q=(5)(4200)(0)
Q= 0 KJ <em>(which indicates that there was no heat gain or loss by the system)</em>
