Answer: by a factor of √2

Explanation:

The kinetic energy is written as:

K = (m/2)*v^2

where m is the mass of the particle and v is the velocity:

If we double the kinetic energy, we have:

k' = 2k = 2(m/2)*v^2

now we want to see by what factor is increased the velocity, so we must put that 2 inside the square power, this is:

k' = 2*(m/2)*(v)^2 = (m/2)*(√2*v)^2 is the new kinetic energy,

This means that the velocity is increased by a factor of √2

A student sits at rest on a piano stool that can rotate without friction. The moment of inertia of the student-stool system is 4

irina [24]

Here We can use principle of angular momentum conservation

Here as we know boy + projected mass system has no external torque

Since there is no torque so we can say the angular momentum is conserved

$mvL = (I + mL^2)\omega$

now we know that

m = 2 kg

v = 2.5 m/s

L = 0.35 m

I = 4.5 kg-m^2

now plug in all values in above equation

$2\times 2.5 \times 0.35 = (4.5 + (2\times 0.35^2))\omega$

$1.75 = [4.5 + 0.245]\omega$

$1.75 = 4.745\omega$

$\omega = 0.37 rad/s$

so the final angular speed will be 0.37 rad/s

1. How do you determine which between the two object has a greater amount of potential energy?

jeka94

Answer:

All of these answers are dependent upon the specific scenario, but here are some general answers.

1. An object with a greater height will have more potential energy.

2. Potential energy can be changed into kinetic energy as an object falls. It loses height (potential energy) and gains speed (kinetic energy).

3. Depends on what scenario your class had.

Both of them are magnets coiled by wires.

1. The wire coiled in the first diagram, the wire is having current, Making the magnetic feild of the magnet more........

2. The wire coiling the magnet is here not having electric current making the magnetic feild smaller
