What units must the constant G have in order for the u it’s F to be newtons (N)?

Physics
1 answer:
EleoNora [17]3 years ago
5 0

The units for G must be [N][m^2][kg^{-2}]

Explanation:

The magnitude of the gravitational force between two objects is given by:

F=G\frac{m_1 m_2}{r^2}

where

F is the force

G is the gravitational constant

m_1, m_2 are the masses of the two objects

r is the separation between the objects

We know that:

  • The units of F are Newtons (N)
  • The units of m_1,m_2 are kilograms (kg)
  • The units of r are metres (m)

So, we can rewrite the equation in terms of G, to find its units:

G=\frac{Fr^2}{m_1 m_2}=\frac{[N][m]^2}{[kg][kg]}=[N][m^2][kg^{-2}]

A hot air balloon has a volume of 65,00 cubic feet of hot air. The balloon is at sea level on a standard day. If the temperature
seraphim [82]
If you heat that air by 100 degrees F, it weighs about 7 grams less. Therefore, each cubic foot of air contained in a hot air balloon can lift about 7 grams. That's not much, and this is why hot air balloons are so huge -- to lift 1,000 pounds, you need about 65,000 cubic feet of hot air.

A crate is being lifted into a truck. If it is moved with a 2470 N force and 4850 J of work is done, then how far is the crate b
olchik [2.2K]

Answer:1.96m

Explanation:

Work=4850J

Force=2470N

Distance =work ➗ force

Distance =4850 ➗ 2470

Distance =1.96m

A 73-kg boy is surfing and catches a wave which gives him an initial speed of 1.6 m/s. He then drops through a height of 1.60 m,
Gnesinka [82]

To solve this problem it is necessary to apply the concepts related to the Conservation of Energy, for which it is necessary that any decrease made through the potential energy, is equivalent to the gain given in the kinetic energy or vice versa.

Mathematically this can be expressed as

KE_i+PE_i = KE_f+PE_f

Since there is no final potential energy (the height is zero), and the initial potential energy is equivalent to the work done we have to

W = KE_f-KE_i-PE_i

W = \frac{1}{2}mv_f^2-\frac{1}{2}mv_i^2 -mgh

W =\frac{1}{2} m(v_f^2-v_i^2)-mgh

W= \frac{1}{2}(73)(8.5^2-1.6^2)-(73*9.8*1.6)

W= 1399.045J

W= 1.4kJ

Therefore the non-conservative work was done on the boy is 1.4kJ

For an increase in the bulk modulus of a material but without any change in the density, what happens to the speed of sound in t
vazorg [7]
The speed of sound, c, is given by the Newton-Laplace formula
c = \sqrt{ \frac{K}{\rho} }
where
K = bulk modulus
ρ =  density

Because the density is constant, the speed of sound is proportional to the square root of the bulk modulus.

Therefore when the bulk modulus increases, the speed of sound increases by the square root of the bulk modulus.

For example, if K is doubled, then
c = \sqrt{2K} = \sqrt{2} \sqrt{K}

Answer:
If the bulk modulus increases by a factor of n, then c increases by a factor of √n.
