Answer:

The force, exerted by Big Ben on the Empire State Building is 2.66972 × 10⁻⁷ N

Explanation:

The question relates to the force of gravity experienced between two bodies

The given parameters are;

The mass of Big Ben, M₁ = 1 × 10⁸ kg

The mass of the Empire State Building, M₂ = 1 × 10⁹ kg

The distance between the two Big Ben and the Empire State Building, r = 5,000,000 meters

By Newton's Law of gravitation, we have;

[tex]F=G \times \dfrac{M_{1} \times M_{2}}{r^{2}}[/tex]

Where;

F = The force exerted by Big Ben on the Empire State Building and vice versa

G = The universal gravitational constant = 6.67430 × 10⁻¹¹ N·m²/kg²

M₁, M₂, and r are the given parameters

By plugging in the values of the parameters and the constant into the equation for Newton's Law of gravitation, we have;

[tex]F=6.67430 \times 10^{-11} \times \dfrac{1 \times 10^8 \times 1 \times 10^9}{(5,000,000)^{2}} = 2.66972 \times 10^{-7}[/tex]

The force, 'F', exerted by Big Ben on the Empire State Building is F = 2.66972 × 10⁻⁷ N.

Answer:

The longer the length of string, the farther the pendulum falls; and therefore, the longer the period, or back and forth swing of the pendulum. The greater the amplitude, or angle, the farther the pendulum falls; and therefore, the longer the period.

Explanation:

Answer:

Position A/Position E

[tex]K = E[/tex], [tex]U = 0[/tex]

Position B/Position D

[tex]K = (1-x)\cdot E[/tex], [tex]U = x\cdot E[/tex], for [tex]0 < x < 1[/tex]

Position C

[tex]K = 0[/tex], [tex]U = E[/tex]

Explanation:

Let suppose that ball-Earth system represents a conservative system. By Principle of Energy Conservation, total energy ([tex]E[/tex]) is the sum of gravitational potential energy ([tex]U[/tex]) and translational kinetic energy ([tex]K[/tex]), all measured in joules. In addition, gravitational potential energy is directly proportional to height ([tex]h[/tex]) and translational kinetic energy is directly proportional to the square of velocity.

Besides, gravitational potential energy is increased at the expense of translational kinetric energy. Then, relative amounts at each position are described below:

Position A/Position E

[tex]K = E[/tex], [tex]U = 0[/tex]

Position B/Position D

[tex]K = (1-x)\cdot E[/tex], [tex]U = x\cdot E[/tex], for [tex]0 < x < 1[/tex]

Position C

[tex]K = 0[/tex], [tex]U = E[/tex]
