The diagram below shows two bowling balls, A and B, each having a mass of 7.0 kg, placed 2.00 m apart between their centers. Find the magnitude of Gravitational Force?

Answer:

The gravitational force is given by Newton's Gravitational Law as follows:

F = Gm₁m₂/r²

where,

F = Gravitational Force = ?

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = m₂ = mass of each ball = 7 kg

r = distance between balls = 2 m

Therefore,

F = (6.67 x 10⁻¹¹ N.m²/kg²)(7 kg)(7 kg)/(2 m)²

A 10 kg ball is falling on the planet Mars. Mars has an acceleration due to gravity of about 4 m/s/s. What is the force of gravi

sineoko [7]

Answer:

The force of gravity = 40 N

Explanation:

Given that,

The mass of a ball, m = 10 kg

The acceleration due to gravity on the surface of Mars, a = 4 m/s²

We need to find the force of gravity of the ball on Mars. The force of gravity on an object is given by :

F = mg

Substitute all the values,

F = 10 kg × 4 m/s²

F = 40 N

Hence, the correct option is (B).

Light of wavelength 578.0 nm is incident on a narrow slit. The diffraction pattern is viewed on a screen 62.5 cm from the slit.

Answer:

$80.6\mu m$

Explanation:

When light passes through a narrow slit, it produces a diffraction pattern on a distant screen, consisting of several bright fringes (constructive interference) alternated with dark fringes (destructive interference).

The formula to calculate the position of the m-th maximum in the diffraction pattern produced in the screen is:

$y=\frac{m\lambda D}{d}$
