Answer:

a) equal 1, b) less than 1

Explanation:

a) the electric force is given by

Fe = q E

The charge of the electron and proton has the same value, that of the proton is positive and that of the electron is negative

Proton

Fp = qE

Electron

Fe = - q E

Fp / Fe = -1

If we do not take into account the sign the relationship is equal to one (1)

b) to calculate the force we use Newton's second law

F = ma

qE = m a

a = q E / m

The mass of the proton much greater than the mass of the electron

ap = q E / $m_{p}$

ae = - q E / $m_{e}$

ap / ae = $m_{e}$ / $m_{p}$ = $m_{e}$ /1600 $m_{e}$ =1/1600

It is much smaller than 1

A disk of mass M and radius R rotates at angular velocity ω0. Another disk of mass M and radius r is dropped on top of the rotat

AleksandrR [38]

Answer:

$\omega = \frac{(R^2\omega_o}{(R^2 + r^2)}$

Explanation:

As we know that there is no external torque on the system of two disc

then the angular momentum of the system will remains conserved

So we will have

$L_i = L_f$

now we have

$L_i = (\frac{1}{2}MR^2)\omega_o$

also we have

$L_f = (\frac{1}{2}MR^2 + \frac{1}{2}Mr^2)\omega$

now from above equation we have

$(\frac{1}{2}MR^2)\omega_o = (\frac{1}{2}MR^2 + \frac{1}{2}Mr^2)\omega$

now we have

$\omega = \frac{MR^2\omega_o}{(MR^2 + Mr^2)}$

$\omega = \frac{(R^2\omega_o}{(R^2 + r^2)}$

1. Define friction. Name and describe two kinds of friction.

jeka57 [31]

Answer:

Friction is a force that holds back the movement of a sliding object.

Explanation:

The two types of friction: Static friction and Kinetic friction. Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion.
