Probably because the earth is stationary rotating on its axis whereas the baseball is the one doing all of the movement after being thrown
I need more to answer this
Answer:
![\tau = 7.63 Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D%207.63%20Nm)
Explanation:
As we know that moment of force is given as
![\tau = \vec r \times \vec F](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%5Cvec%20r%20%5Ctimes%20%5Cvec%20F)
now we have
![\vec r = 1.2 m](https://tex.z-dn.net/?f=%5Cvec%20r%20%3D%201.2%20m)
![\vec F = 14 N](https://tex.z-dn.net/?f=%5Cvec%20F%20%3D%2014%20N)
now from above formula we have
![\tau = r F sin\theta](https://tex.z-dn.net/?f=%5Ctau%20%3D%20r%20F%20sin%5Ctheta)
here we know that
![\theta = 27 degree](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2027%20degree)
so we have
![\tau = (1.2)(14) sin27](https://tex.z-dn.net/?f=%5Ctau%20%3D%20%281.2%29%2814%29%20sin27)
![\tau = 7.63 Nm](https://tex.z-dn.net/?f=%5Ctau%20%3D%207.63%20Nm)
Because of the build up of pressure. There is so much steam coming from such a compressed point, it’s coming out in force.
Now think of that same spot being closed, it only has one place to go but it can’t leave, so that pressure will build and build and then BOOM, it explodes.
In short, the answer is the pressure being released from a small point, and how that energy is released.
Answer:
Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320.
Explanation:
The universal law of gravitation states that the force between two objects in the universe is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
We have to choose the satellite having greatest gravitational force with earth. In all options the distance from the earth is same i.e. 320 km. So, we have to select the satellite having maximum mass because the mass of the earth is constant.
Hence, the correct option is (D) " Satellite D has a mass (kg) of 500 and the distance from Earth (km) is 320 ".
