Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.

First Car : 0.5 * 2000kg * 3m/s^2 = 10.24 KJ

Second Car : 0.5 * 2000kg * 2m/s^2 = 4 KJ

Leftover Energy : 10.24 KJ - 4 KJ = 6.24 KJ

Movement of BOTH cars :
6.24 = 4000kg * v^2
v = √(6.24 / 4000) =0.04 m/s = 4 cm/s

The muzzle velocity of a gun is the velocity of the bullet when it leaves the barrel. The muzzle velocity of one rifle with a sh

Anvisha [2.4K]

Answer:small barrel gun

Explanation:

Given

Muzzle velocity of bullet is greater in short barrel gun as compared to larger barrel gun

acceleration is given by change in velocity with respect to time

$a=\dfrac{\Delta v}{\Delta t}$

In case of short barrel bullet time taken by bullet to reach its muzzle velocity is less therefore acceleration of small barrel bullet is more compared to long barrel bullet.

A sphere of radius 0.03m has a point charge of q= 7.6 micro C located at it’s centre. Find the electric flux through it?

GalinKa [24]

Answer:

The electric flux through the sphere is $8.58 *10^{5} \frac{Nm^2}{C}$

Explanation:

Given

$Radius,\ r = 0.03m\\Charge,\ q =7.6\µC$

Required

Find the electric flux

Electric flux is calculated using the following formula;

Ф = q/ε

Where ε is the electric constant permitivitty

ε $= 8.8542 * 10^{-12}$

Substitute ε $= 8.8542 * 10^{-12}$ and $q =7.6\µC$ ; The formula becomes

Ф = $\frac{7.6\µC}{8.8542 * 10^{-12}}$

Ф = $\frac{7.6 * 10^{-6}}{8.8542 * 10^{-12}}$

Ф = $\frac{7.6}{8.8542} *\frac{10^{-6}}{10^{-12}}$

Ф = $\frac{7.6}{8.8542} *10^{12-6}}$

Ф = $0.85834970974 *10^{12-6}}$

Ф = $0.85834970974 *10^{6}}$

Ф = $8.5834970974 *10^{5}}$

Ф = $8.58 *10^{5} \frac{Nm^2}{C}$

Hence, the electric flux through the sphere is $8.58 *10^{5} \frac{Nm^2}{C}$

If a person lives in china in which two hemispheres does he or she live

Delvig [45]

on the globe , the largest continent on earth , asia lies in between eastern and northern hemisphere. it is also known that country china comes in asian continent. hence we can say that china also lies in between eastern and northern hemisphere.

hence the two hemispheres are northern and eastern.
