An object has 100 J of kinetic energy and a mass of 2 g. How fast was it traveling?
iragen [17]

K.E = 1/2 mv²

100   = 1/2 (2 )(v)²

100  = both  2 cancel (v)²

Taking Square root on b/s

√100 = √v²

10  = v

The force of gravity between two objects is directly proportional to which of the following?
WINSTONCH [101]
The answer is:
D: The distance between the objects squared.

The gravitational force between two objects is proportional to their masses and inversely proportional to the square of the distance between their centers. Result: 'g' is independent of mass of object !! Hope this helped :)

The constellation Canis Minor has a binary star system consisting of Procyon A and Procyon B. Procyon A, at 3×1030kg, has 2.5 ti
denis-greek [22]

This question involves the concepts of Newton's Law of Gravitation and mass.

The force on Procyon A from Procyon B will be "equal" to the force on Procyon B from Procyon A, which has a value of "3.75 x 10²⁶ N".

Applying Newton's Law of Gravitation, we can find the force on Procyon A from Procyon B, which is equal to the force on Procyon B from Procyon A:

F=\frac{Gm_1m_2}{r^2}

where,

F = force = ?

G = universal gravitational constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = mass of Procyon A = 3 x 10³⁰ kg

m₂ = mass of Procyon B = (2.5)(3 x 10³⁰ kg) = 7.5 x 10³⁰ kg

r = distance between them = 2 x 10¹² m

Therefore,

F=\frac{(6.67\ x\ 10^{-11}\ N.m^2/kg^2)(3\ x\ 10^{30}\ kg)(7.5\ x\ 10^{30}\ kg)}{(2\ x\ 10^{12}\ m)^2}

<u>F = 3.75 x 10²⁶ N</u>
