Bare free charges do not remain stationary when close together. To illustrate this, calculate the acceleration of two isolated p
Natali5045456 [20]

Answer:

Acceleration, a=3.6\times 10^{16}\ m/s^2

Explanation:

It is given that, two isolated protons are separated by 2 nm. The force due to charged particles is given by :

F_e=\dfrac{kq^2}{d^2}

Force due to mass of proton, F_g=ma

ma=\dfrac{kq^2}{d^2}

a=\dfrac{kq^2}{md^2}

a=\dfrac{9\times 10^9\times (1.6\times 10^{-19})^2}{1.6\times 10^{-27}\times (2\times 10^{-9})^2}

a=3.6\times 10^{16}\ m/s^2

So, the acceleration of two isolated protons is 3.6\times 10^{16}\ m/s^2. Hence, this is the required solution.

What does K stand for in Hookes law?
wlad13 [49]
So Hooke's law says that that law is proportional to how much I stretch the spring. Alright. So f=kx<span>. x is the length of the spring now minus its length when it's relaxed and nobody's pulling on it. k is a constant called the spring constant.</span>

Which scientific term is defined as the rate at which work is accomplished?
Oliga [24]

Power is the scientific term defined as the rate at which work is accomplished. Power can be seen everywhere as it is applied to our everyday living. Power is seen when one pushes a heavy cart. It could be seen when a baseball hitter hits the ball.

According to Ohm’s law, which combination of units is the same as the unit for resistance? volt ÷ ampere ampere × volt volt + am
Maksim231197 [3]

Answer:

volt ÷ ampere

Explanation:

The mathematical form of Ohms law is given by :

V = IR

Where V is voltage

I is current

R is resistance

R=\dfrac{V}{I}

The unit of voltage is volt and that of current is ampere

Unit of resistance :

R=\dfrac{\text{volt}}{\text{ampere}}

So, volt ÷ ampere is the same as the unit of resistance. Hence, the correct option is (a).
