What does Kinetic Energy depend on

1 answer:

8 0

Since kintetic energy is the energy of motion it depends on the two mass affects inertia and inertia applies to kinetic energy. and speed is applied because the faster it going the more kinetic energy the object has.

For the different values given for the radius of curvature RRR and speed vvv, rank the magnitude of the force of the roller-coas

nirvana33 [79]

Explanation:

The force of the roller-coaster track on the cart at the bottom is given by :

$F=\dfrac{mv^2}{R}$ , m is mass of roller coaster

Case 1.

R = 60 m v = 16 m/s

$F=\dfrac{(16)^2m}{60}=4.26m\ N$

Case 2.

R = 15 m v = 8 m/s

$F=\dfrac{(8)^2m}{15}=4.26m\ N$

Case 3.

R = 30 m v = 4 m/s

$F=\dfrac{(4)^2m}{30}=0.54m\ N$

Case 4.

R = 45 m v = 4 m/s

$F=\dfrac{(4)^2m}{45}=0.36m\ N$

Case 5.

R = 30 m v = 16 m/s

$F=\dfrac{(16)^2m}{30}=8.54m\ N$

Case 6.

R = 15 m v =12 m/s

$F=\dfrac{(12)^2m}{15}=9.6m\ N$

Ranking from largest to smallest is given by :

F>E>A=B>C>D

Flashlight has resistance of 2.4 what voltage is applied by the batteries if the current is 2.5a

Sergeeva-Olga [200]

Answer:

6 voltage is applied by the batteries.

Explanation:

To solve this sort of problem involving current, resistance and voltage, we use the relation: Voltage= Current x Resistance.

From the problem, the following have been given:

Resistance= 2.4 ohms.

Current= 2.5 amps.

Required: Voltage?

Fix the values of current and resistance into the relation:

Voltage= 2.5 x 2.4

=6 volts.

An excited hydrogen atom releases an electromagnetic wave to return to its normal state. You use your futuristic dual electric/m

masya89 [10]

Answer: the magnetic wave will travel out of the screen.

Explanation:

Electric field direction is perpendicular to the magnetic field direction. Both are also perpendicular to the direction of the particles.

Using right hand rule to solve this problem,

This pointed finger depicts the electric field direction which the curly fingers depict the direction of the magnetic field. The pointed thumb will depict the direction in which the wave travel. Which is out of the screen.
