If you are about to be hit from behind, your best course of action is to brake gently and stop the car.

Elza [17]

ANSWER: B. False

Stopping when there is a speeding car about to hit you from behind would be the most illogical thing to do as this would increase the impact of collision. This is because you will certainly be propelled forwards with a speed as fast as the car behind you. This is according to the concept of momentum and collisions.

The low-frequency speaker of a stereo set has a surface area of and produces 1W of acoustical power. What is the intensity at th

AlekseyPX

Answer:

I = $\frac{1}{4\pi \ r^2}$

we see the intensity decreases with the inverse of the distance squared

Explanation:

Intensity is defined as power per unit area,

I = P / A

in this case we have that the sound is emitted in a spherical form therefore the area is

A = 4 pi r2

therefore the intensity is

I = $\frac{1}{4\pi \ r^2}$

as we see the intensity decreases with the inverse of the distance squared

What is the energy stored between 2 Carbon nuclei that are 1.00 nm apart from each other? HINT: Carbon nuclei have 6 protons and

Andrei [34K]

Answer:

$A. 8.29\times 10^{-18}\ J$

Explanation:

Given that:

p = magnitude of charge on a proton = $1.6\times 10^{-19}\ C$

k = Boltzmann constant = $9\times 10^{9}\ Nm^2/C^2$

r = distance between the two carbon nuclei = 1.00 nm = $1.00\times 10^{-9}\ m$

Since a carbon nucleus contains 6 protons.

So, charge on a carbon nucleus is $q = 6p=6\times 1.6\times 10^{-19}\ C=9.6\times 10^{-19}\ C$

We know that the electric potential energy between two charges q and Q separated by a distance r is given by:

$U = \dfrac{kQq}{r}$

So, the potential energy between the two nuclei of carbon is as below:

$U= \dfrac{kqq}{r}\\\Rightarrow U = \dfrac{kq^2}{r}\\\Rightarrow U = \dfrac{9\times10^9\times (9.6\times 10^{-19})^2}{1.0\times 10^{-9}}\\\Rightarrow U =8.29\times 10^{-18}\ J$

Hence, the energy stored between two nuclei of carbon is $8.29\times 10^{-18}\ J$ .
