83 km/h * 2.5 hours (3:30 - 1:00) = 207.5 km  

207.5 km - 15 km = 192.5 km

The atom in the diagram has a neutral charge how many protons does it have
Olegator [25]

Explanation:

This should be of help:

An atom is made up of three subatomic particles:

  • Protons are the positively charged particles.
  • Electrons are the negatively charged particles.
  • Neutrons do not carry any charges.

A neutral atom is an atom that has not lost or gained any amount of electrons.

In a neutral atom;

                the number of protons and electrons are the same

 Usually atoms are designated this way:

                                                  ᵃₙX

  where X is the symbol of the atom

               a is the mass number of the atom

                n is the atomic number of the atom

 The mass number = number of protons + number of neutrons

        Atomic number = number of protons

Note; atomic number is the same as the number protons and the number of electrons in a neutral atom.

A system consists of a disk rotating on a frictionless axle and a piece of clay moving toward it, as shown in the figure above.
cestrela7 [59]

Explanation:

Forgive me If I am wrong, it's been a while since I've studied Torque.

The formula for the angular momentum is

momentum= I*w.

We can also write I*W as 1/2MR^2 * W so the extra mass coming from the block of clay would most likely cause the angular momentum to increase from the amount it was before.

If the 50 kg boy were in a spacecraft 5.0r from the center of the earth, what would his weight be?
Lady_Fox [76]
·The acceleration of gravity is proportional to

                       1 / (the square of the distance from the center) .

When we're on the surface, we're 1 radius from the center of the Earth,
and the acceleration of gravity is  9.8 m/s² .

The boy's weight = (mass) · (gravity) = (50kg) · (9.8 m/s²)

                                                             =      490 newtons .

At the distance of 5 radii from the center (4 radii altitude from the surface),
the acceleration of gravity is

                 (9.8 m/s²) · (1/5)²  =  0.39 m/s² .

The boy's weight is    (mass) · (gravity)  =  (50kg) · (0.39 m/s²)

                                                                  =     19.6 newtons .

Just as we expected, his weight at that distance is

         (19.6 / 490) = 0.04  =  1/25  =  1/5²  of his weight on the surface.
