Answer:

A positive charge means lack of electrons.

Explanation:

Atoms that are present in all bodies, are composed of electrons, protons and neutrons. All three have mass, but only the electron and the proton have charge. The electron has a negative charge, and the proton has a positive charge.

In a neutral atom, the number of protons coincides with the amount of electrons. But it may happen that these amounts are different.

When there are excess electrons, as these have a negative charge, the charge of the element will be negative. Then an anion is formed.

However, when there is a lack of electrons, the element's charge will be positive. Then a cation is formed.

So, <u><em>a positive charge means lack of electrons.</em></u>

I believe it’s (b) since negative charge means having two or more extra electrons

200N=55x
200/55=3.636......
3.636...-2=1.636.....
1.636 is the deceleration resulting from friction hence the force of friction is 1.636*55=90newtons
90newtons*distance of 10 meters= 900 j of work done by friction

While describing a circular orbit 300 mi above the earth a space vehicle launches a 6000-lb communications satellite. Determine
yarga [219]

Answer:

\Delta U = 2.2126039 x 10^{12} J

Explanation:

While the satellite is in the space vehicle, it has the next potential energy

U = -\frac{GmMe}{r}

             where G is the gravitational constant

                         m is the satellite's mass in kilograms

                        Me is the earth's mass

                        r is the orbit's radius from to the earth's center in meters

U = - \frac{6.67x10^{-11}*2721.554*5.972x10^{24}  }{482803}

U = -2.2423x10^{12} J

The additional energy required is the difference between this energy and the energy that the satellite would have in an orbit with an altitude of 22000 mi

U = -\frac{6.67x10^{-11}*2721.554*5.792x10^{24}  }{35405568}

U = -29696124610.3 J

Then

\Delta U = 2.2126039 x 10^{12} J
