Answer:
Explanation:
The magnitude of the force of a moving cahrge, in our case a proton, trought a magentic field is given by:
(1)
where:
q is the proton charge (
)
v is the proton velocity (
)
B is the magnetic field (B = 1.17 T)
Now, we just need to solve the equaton (1) for \theta.

But the force F = ma, then:
m is the mass of proton (
)
a is the acceleration (
)

I hope it helps you!
Answer:
Protons have about the same mass as electrons is false
Explanation:
Electrons and protons have the same magnitude on charge but opposite sign
: charge of electron
: charge of proton
Neutrons have no charge.
An atom is composed of protons and neutrons in the nucleus and electrons surrounding it, so a neutral atom has the same number of protons and electrons to has a net charge of zero. So, all the facts mentioned are true.
The false one is that protons have about the same mass as electrons, because the mass of an electron is
and the mass of a proton is
so the mass of a proton is a lot of bigger than electron mass.
Answer:
7 m/s
Explanation:
To solve this problem you must use the conservation of energy.

That math speak for, initial kinetic energy plus initial potential energy equals final kinetic energy plus final potential energy.
The initial PE (potential energy) is 0 because it hasn't been raised in the air yet. The final KE (kinetic energy) is 0 because it isn't moving. This gives the following:


K1=U2

Solve for v

Input known values and you get 7 m/s.
Answer:
Dry lubricants or solid lubricants are materials that, despite being in the solid phase, are able to reduce friction between two surfaces sliding against each other without the need for a liquid oil medium.
