Here, F = m * a
F = m * v/t
Here, m = 81 Kg
v = 22 m/s
t = 1,4 s
Substitute their values,
F = 81 * 22/1.4
F = 81 * 15.71
F = 1273 N
So, Closest value from your options is 1300 N
In short, Your Answer would be Option B
Hope this helps!
Answer:
Explanation:
From the question we are told that:
Coefficient of kinetic friction 
Vertical Mass 
Horizontal mass 
Generally the equation for kinetic force 
is mathematically given by
Generally the equation for T is mathematically given by
For 
Therefore substituting
Answer: Option (E) is the correct answer.
Explanation:
Latent heat is defined as the amount of heat required by per mole of a substance in order to change its state.
And, latent heat of freezing (fusion) is defined as the energy required for the phase change between a liquid and a solid without any change in their temperature.
Therefore, at zero degrees Celsius energy absorbed by the ice will be consumed in breaking the bond between the water molecules held together in the solid state.
Thus, we can conclude that when a block of ice at zero degrees Celsius melts, the ice absorbs energy but does not change its temperature.
Answer:
the density of indium is 7.2 g/cm^3
Explanation:
The computation of the density of indium is shown below:
Given that
Mass = 16.6 g
Volume = 48.6 c,^3 - 46.3cm^3 = 2.3 cm^3
Based on the above information
As we know that
Density = mass ÷ volume
So,
= 16.6g ÷ 2.3 cm^3
= 7.2 g/cm^3
hence, the density of indium is 7.2 g/cm^3
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Answer:
It is found that W1 - W2 loss in weight of solid when immersed in water is equal to the weight of the water displaced by the body. This verifies Archimedes' principle.
