Answer:

It depends on the mass of each of the bodies, and the distance that separates them.

Explanation:

The force of attraction between two objects depends on the mass of each of the bodies as well as the distance that separates them. This force can be easily calculated by means of the universal gravitation law formulated by Newton.

Next, we will see the equation that explains the law of universal gravitation.

$F=G*\frac{m_{1}*m_{2} }{r^{2} } \\where:\\G = 6.67 *10^{-11} [N*m^{2}/kg^{2} ]\\\m_{1} = mass of the small body [kg]\\m_{2} = mass of the large body [kg]\\\r= distance between the bodies[m]$

The rotational kinetic energy term is often called the kinetic energy in the center of mass, while the translational kinetic ene

weqwewe [10]

Answer:

Explanation:

The total kinetic energy is the sum of the kinetic energy in the center of mass (Rotational Kinetic energy) plus the kinetic energy of the center of mass( Translational Kinetic Energy).

The formula

$K_{tot} = K_{t} +K_{r}$ is applicable only when

The moment of inertia must be taken about an axis through the center of mass.

Sonja [21]

Answer:

a) 800 km

b) 9.79° & 12.47°

Explanation:

It is known that the wavelength of any material or substance is given by the relation 入 = v/f

From the question, the time between the crest is given as 1.0 h, therefore, t = 1.0 h

Also, remember that frequency, f can be represented by

f = 1/t, and thus,

f = 1/1.0 h = 1.0 h^-1. This is our frequency, and would be used in the primary stated formula

入 = v/f, from the question, the speed is already stated as 800 km/h, so we apply directly

入 = 800 / 1

入 = 800 km. Therefore, the wavelength of the tsunami is 800 km

the smallest angle between the Southern tip of Africa is

Sinθ = 800 / 4500

Sinθ = 0.17

θ = Sin^-1 0.17

θ = 9.79°

The smallest angle between the Southern end of Australia is

Sinθ = 800 / 3700

Sinθ = 0.216

θ = Sin^-1 0.216

θ = 12.47°
