If you think about it, it makes a right triangle when you combine all the different types of forces together such as v, vx and vy. Then, you can use trigonometry and soh cah toa in order to figure out vx.

A system consists of electrons and protons only. It contains 150 electrons and has a total charge of +22e. What is the mass of t
liubo4ka [24]

According to the statements the number of electrons is 150, then

e = 150

But there is a positive charge of +22e, then the number of protons would be

p = 150+172

If the mass of the electrons is

m_e = 9.11*10^{-31} kg

And the mass of the protong is

m_p = 1.673*10^{-27}kg

We have that the total mass of the system would be

m = e*m_e +pm_p

m = 150 * (9.11*10^{-31})+170(1.673*10^{-27})

m = 2.84547*10^{-25} kg

What happens to gas that is not used
kvv77 [185]
the engine won't start or it sputters when it should be running perfectly. if the gasoline is old and stale, it will have lost a portion of its volatility. the lighter components of the gasoline (remember, gasoline is a mixture of different hydrocarbons) have probably evaporated off or disappeared.

Use newton's third law to explain why a blown up balloon but untied balloon will fly around the room when you let it go? really
sergij07 [2.7K]
Newton's third law states that for every action, there is an equal and opposite reaction. When you let go of the ballon, you are letting the force out but the force also pushes the balloon back.
