m_a_m_a [10]

Hello,

<u>Solution for A:</u>

Force = 3.00N

Mass = 0.50 Kgs

Time = 1.50 Seconds

According to newton's second law of motion;

Force = Mass times Acceleration(a)

3.00 = 0.50 * a

a = 3.00/0.50 = 6.00 m/s^2

We know that acceleration = Velocity / time

So Velocity = time * acceleration = 1.50 * 6 = 9.00 m/s^2

<u>Solution for B:</u>

The net force = 4.00N - 3.00N = 1.00N to the left

Force = 1.00N

Mass = 0.50Kg

Time = 3.00 Seconds

Again; F = MA (Where F is force, M is mass and A is acceleration)

1.00N = 0.5 * A

A = 1/0.5 = 2 m/s^2

Velocity = Acceleration * Time = 2 * 3 = 6 m/s

The acceleration due to gravity is g at the earth's surface. an earth satellite is orbiting at a distance from the earth's surfa
disa [49]

The acceleration due to gravity is g/4

The acceleration above the earth surface is given by the relation

g^'=gr^2/〖(h+r)〗^2

Since the satellite orbits the earth in a orbit of radius equal to earth radius, therefore

g^'=(gr^2)/〖(r+r)〗^2 =g/4

Thus the acceleration due to gravity on the satellite is g/4.

Neon signs use electricity to ____ electrons
Romashka [77]
Neon light recharge them self with more light and electricity, they rapidly give out the energy they absorbed to get themselves back to normal again. They do this by giving out tiny packets of light energy called photons. I;m not sure if this helps but you gave no info really on what you were asking like if there were choices that would have been helpful to see :p

A proton and an electron are released from rest in the center of a capacitor.
Sunny_sXe [5.5K]

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

When an electron enters a magnetic field, it will accelerate up the field. True OR False
liq [111]

Answer:

True

Explanation:

The force on the electron when it enters in a magnetic field is given by

F = q ( v x B)

F = -e x V x B x Sin∅

here, F is the force vector, B be the magnetic field vector and v be the velocity vector.

If the angle between the velocity vector and the magnetic field vector is 0 degree, then force is zero.

When the electrons enters in the magnetic field at any arbitrary angle, it experiences a force and hence it accelerate up.
