It’s the type of eclipse that occurred when the moon passes between the sun and earth, and when the moon fully or partially blocks the sun.

A physics teacher performing an outdoor demonstration suddenly falls from rest off a high cliff and simultaneously shouts help.
GrogVix [38]

Answer:

H = 532 m

Explanation:

When teacher falls into the cliff then she shout for Help at the same time

so here we know that sound will go down and reflect back up

so here in 3 s distance traveled by the sound

d = vt

d = 340 \times 3

d = 1020 m

now in the same time the distance that teacher will fall down is given as

d_1 = \frac{1}{2}gt^2

d_1 = \frac{1}{2}(9.81)(3^2)

d_1 = 44.1 m

now total distance traveled by teacher and sound in 3 s

d_{total} = d + d_1

d_{total} = 1020 + 44.1

this total distance must be equal to twice the height of the cliff

2H = 1064.1 m

H = 532 m

Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a ligh
guapka [62]

Answer:

This is because the acceleration of objects due to gravity is independent of the mass of the object and is constant for all objects, therefore, all objects fall with the same speed.

Explanation:

The weight of an object or force of gravity acting on an object on the surface of earth is a product of its mass and acceleration due to gravity.

Mathematically, w = mg

where, m=mass of the object; g = acceleration due to gravity

Also, from newton's law of gravitation, gravitational force on the object ,F = GMm/r²

where G is the gravitational constant; M is mass of Earth; m is mass of object; r is the distance of separation between the object and the center of mass of the earth which is approximately the radius of earth.

Since the weight of an object is equal to the force of gravitation acting on it

W = F

mg = GMm/r²

g = GM/r²

The expression above is that of the relationship between the force of gravity acting on a body on the earth's surface, the weight of that body and the acceleration due to gravity, g.

It can be seen that the acceleration due to gravity g is independent of the mass of the object. Therefore, the acceleration of objects due to gravity is constant for all objects and all objects fall with the same speed.
