Answer:
<u>36 m</u>
Explanation:
We can consider this to be an AP.
Then,
<u>Subtract a₇ from a₉.</u>
- a + 8d - a + 6d = 24 - 20
- 2d = 4
- d = 2
<u>Finding a₁₅</u>
- a₁₅ = a + 14d
- a₁₅ = 8 + 14(2)
- a₁₅ = 8 + 28
- a₁₅ = <u>36 m</u>

Gravitational Potential of an object with mass m, and height of h metre is :
Now, if the mass of object is 2100 kg, height of 18 m is placed in there, then it's gravitational potential energy is ~
For a curved mirror, all points have the same normal and the angle of incidence is also equal to the angle of reflection.
According to the laws of reflection, the incident ray, reflected ray and normal all lie on the same plane. For a curved mirror, the normal remains the same at all points along the curved mirror.
Again, the angle made between the incident ray and the normal is the same as the angle made between the reflected ray and the normal. Therefore, the angle of reflection is equal to the angle of incidence.

Answer:
Fgrav. = GM1×M2/R2
Explanation:
Gravitational force is mostly related
to planetary bodies by Newton's law of gravitation which states that the gravitional force is proportional to the product of the mass of the object and inversely proportional to the square of the distance between them.
Hence in this case the Gravitational force,
Fgrav. = GM1×M2/R2
M1 and M2 are the mass of the two students and R is their distance apart
G is a constant known as gravitational constant.6.67408 × 10-11 m3/kgs2
