What is the relationship between the masses of the objects and the gravitational force between them

The relationship between the masses of the object and the gravitational force between them is a direct relationship

Explanation:

The gravitational force between two objects is given by  the equation:

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

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

We observe that:

- The gravitational force is proportional to the masses of the two objects, m1 and m2, so if the masses increase, the force will increase as well (so, this is a direct relationship)

- The gravitational force is inversely proportional to the square of the separation between the objects, so if the distance is increased, the force will decrease (so, this is an inverse relationship)

The Great Sandini is a 60 kg circus performer who is shot from a cannon (actually a spring gun). You don't find many men of his
Alex17521 [72]

Answer:

22m/s

Explanation:

Mass, m=60 kg

Force constant, k=1300N/m

Restoring force, Fx=6500 N

Average friction force, f=50 N

Length of barrel, l=5m

y=2.5 m

Initial velocity, u=0

F_x=kx

Substitute the values

6500=1300x

x=\frac{6500}{1300}=5m

Work done due to friction force

W_f=fscos\theta

We have \theta=180^{\circ}

Substitute the values

W_f=50\times 5cos180^{\circ}

W_f=-250J

Initial kinetic energy, Ki=0

Initial gravitational energy, U_{grav,1}=0\

Initial elastic potential energy

U_{el,1}=\frac{1}{2}kx^2=\frac{1}{2}(1300)(5^2)

U_{el,1}=16250J

Final elastic energy,U_{el,2}=0

Final kinetic energy, K_f=\frac{1}{2}(60)v^2=30v^2

Final gravitational energy, U_{grav,2}=mgh=60\times 9.8\times 2.5

Final gravitational energy, U_{grav,2}=1470J

Using work-energy theorem

K_i+U_{grav,1}+U_{el,1}+W_f=K_f+U_{grav,2}+U_{el,2}

Substitute the values

0+0+16250-250=30v^2+1470+0

16000-1470=30v^2

14530=30v^2

v^2=\frac{14530}{30}

v=\sqrt{\frac{14530}{30}}

v=22m/s

Which statement does NOT refer to radiation?
fiasKO [112]

B. Warm air rises and takes heat with it; eventually it cools and sinks.

Explanation:

Warm air rising and taking heat with it which eventually cools and sinks describes a typical convection current. This is not radiation

Convection and radiation are both forms of heat transfer alongside conduction.

Radiation is the only form of heat transfer that does not involve the use of a medium or particles.

Air is a medium and it flouts the concept of heat transfer by radiation.

Convection is mostly taking place in fluids especially liquid and gas.

A bird flew 100 meters in 2 minutes. What was the birds speed ? (show all your work below)
Reika [66]

Answer:

50 meters a minute.

Explanation:

speed = distance / time

So we do 100 / 2 = 50.
