Neutrons & Protons.

It is because, Atomic mass = Number of proton + Number of neutrons.

An electron and a proton, starting from rest, are accelerated through an electric potential difference of the same magnitude. in

Yakvenalex [24]

The charges are the same in absolute value, so the change of potential energy is the same. That means that the change in kinetic energy is also the same. Then:

1 = Ke/Kp = m_e *v_e^2 / m_p * v_p^2, or

v_e/v_p = sqrt( m_p/m_e),

So the speed of the electron will be sqrt( m_p/m_e) times greater than the speed of the proton

Two oppositely charged parallel sheets of charge give rise to a field of 9.00×1011 N/C between them. The sheets are square and h

Maksim231197 [3]

Answer:

$Q = 5.75 C$

Explanation:

As we know that due to a thin sheet electric field at a point near its surface is given as

$E = \frac{\sigma}{2\epsilon_0}$

now we have two sheets of opposite charges so the net electric field is double that of field due to one sheet

so we have

$E_{net} = 2E$

$E_{net} = \frac{\sigma}{\epsilon_0}$

$9.00 \times 10^{11} = \frac{Q}{A\epsilon_0}$

now we have

$Q = 9.00 \times 10^{11}(0.85 \times 0.85)(8.85 \times 10^{-12})$

$Q = 5.75 C$

3. A 6 kg block moving to the right at 4 m/s collides with and sticks to a stationary block of unknown mass. If the two blocks m

Sphinxa [80]

Answer: 2kg

Explanation:

This problem is a textbook conservation of momentum problem. The intial momentum is equal to the final momentum. For the initial state of each block, only the first one was moving. Then they both combine to move together.

Pi = Pf

with p = mv

(6kg)*(4m/s) = (6kg+xkg)(3m/s)

Let x equal the unknown mass of block 2

24 = 18 + 3x

6 = 3x

x = 2kg

What are ways to remove static charge

Tasya [4]

Answer:

Explanation:

Use a humidifier. Static electricity is more active when the air is dry, especially in the winter months when people heat their houses, further reducing humidity in the air. ...

Treat your carpets with an anti-static chemical. ...

Rub upholstery with dryer sheets.
