Potential energy is the energy stored in matter because of
its position or because of the arrangement of parts.
Answer:
Option C. The force between them would be 4 times larger than with the
initial masses.
Explanation:
To know which option is correct, we shall determine the force of attraction between the two masses when their masses are doubled. This can be obtained as follow:
From:
F = GMₐM₆/ r²
Keeping G/r² constant, we have
F₁ = MₐM₆
Let the initial mass of both objects to be m
F₁ = MₐM₆
F₁ = m × m
F₁ = m²
Next, let the masses of both objects doubles i.e 2m
F₂ = MₐM₆
F₂ = 2m × 2m
F₂ = 4m²
Compare the initial and final force
Initial force (F₁) = m²
Final (F₂) = 4m²
F₂ / F₁ = 4m² / m²
F₂ / F₁ = 4
F₂ = 4F₁ = 4m²
From the above illustrations, we can see that when the mass of both objects doubles, the force between them would be 4 times larger than with the
initial masses.
Thus, option C gives the correct answer to the question.
Changing frequency of sound does not change the speed of the sound.
Explanation:
- Speed of the sound gets altered when the sound travels from one medium to another.
- Change in frequency does not affect the speed of the sound and speed is affected by the properties of the medium through which it travels.
- Therefore, to change the speed of the sound, the properties of the medium needs to be changed.
Answer:
Explanation:
As we know that if the block will complete the circular motion of the path then the speed at the bottom most part of the path must be equal to
now we know that
velocity at the bottom of the path is due to conversion of potential energy to kinetic energy
so we can say it is given as
now we have
Answer:
Maximum force, F = 1809.55 N
Explanation:
Given that,
Diameter of the anterior cruciate ligament, d = 4.8 mm
Radius, r = 2.4 mm
The tensile strength of the anterior cruciate ligament, 
We need to find the maximum force that could be applied to anterior cruciate ligament. We know that the unit of tensile strength is Pa. It must be a type of pressure. So,
So, the maximum force that could be applied to anterior cruciate ligament is 1809.55 N
