In a collision experiment, the ratio of the velocity change between two carts of equal inertia is found to equal 1.

VashaNatasha [74]

Answer:

A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same

B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same

Explanation:

A vehicle crash problem must be solved with the equation of the moment,

Initial instant Before crash

p₀ = m v₁ + mv₂

After the crash

$p_{f}$ = m $v_{1f}$ + m $v_{2f}$

p₀ = $p_{f}$

If the speed ratio before and after the crash is one

p₀ / $p_{f}$ = 1

We can assume that initially one of the cars was stopped

m v₁₀ = m $v_{2f}$

v₁₀ = $v_{2f}$

For the two speeds to be equal, the masses of the vehicles must be the same.

A) Therefore if I double the masses with are in the two terrine they are simplified and the radii of the speeds remain the same

B) If the masses are maintained and the speeds are doubled, the radius of the two speeds remains the same

It’s your birthday, and to celebrate you’re going to make your first bungee jump. You stand on a bridge 100 m above a raging riv

amm1812

Answer:

$X'=50.4\,m$

Explanation:

Given that:

Height of jump, $h=100\,m$

length of elastic cord, $l=30\,m$

spring constant of the cord, $k=40\,N.m^{-1}$

mass of the body that jumps, $m=80\,kg$

Force on the bungee elastic cord:

$F=m.g$

$F=80\times 9.8$

Now this force F will be responsible for the elongation in the elastic cord, so:

$F=k.x$ ............................(1)

where :

k = spring constant

x = extension in the elastic cord

using eq. (1)

$80\times 9.8=40\times x$

$x=19.6\,m$

So the cord stretches 19.6 meters more beyond its original length of 30 meters.

Hence, the remaining distance from the river surface at the bottom is:

$X'=100-(30+19.6)$

$X'=50.4\,m$

Current is constant at all points in a parallel circuit. True False

Sergio [31]

This is false. Current is the speed of the charge, 1 amp of current is 1 coulomb per second. So you can imagine the current of a circuit as the current of a river. In a parallel circuit, the river breaks into two separate streams. Some of the water goes down one river, some goes down the other. However, the total amount of water/coulombs never changes. This means that some of the total current will go down one river, and one the other. However, with less coulombs now the current will decrease.

Long story short, since there are two paths, the charge will split and depending on the resistance of each parallel stream a different amount of charge will go down each branch.

Which of the following choices is the best example of potential energy?

jekas [21]

Answer:

A basketball sitting still in a players hands

Explanation:

The other 3 answers have the ball in motion (going towards the basket, bouncing, and rolling) so that would be kinetic energy.

When the basketball is sitting in the player's hands, it has the potential to be in motion.
