Answer:
time = energy / power = 15010 / 500 = .... seconds

How would a spinning disk's kinetic energy change if its moment of inertia was five times larger but its angular speed was five times smaller

Hello I would like to know if there is a course or a book in which to learn quantum mechanics is easier, I am currently studying quantum mechanics, but it is a little complicated because I have some mathematical doubts, but nevertheless I would like to know if there is a course or book that explains and develops the problems so that they are understandable. and if there is no book or course I would appreciate an honest and complete answer, thank you very much and greetings.Sorry I know that this is not a problem but what better to ask the experts do not believe.

Information that is easily converted into numbers and is stored as a on and off signals is _____ information.

Imagine that you drop an object of 10 kg, how much will be the acceleration andhow much force causes the acceleration?

The starter motor of a car engine draws a current of 170 A from the battery. The copper wire to the motor is 4.60 mm in diameter and 1.2 m long. The starter motor runs for 0.930 s until the car engine starts How much charge passes through the starter motor?

The distance for both Parts A and B are given in the question.

A balloon drifts **140m** toward the west in 45s.

The wind suddenly changes and the balloon flies **90m** toward the east in the next 25s.

To find the total distance, we can just add.

140 + 90 = **230m**

Best of Luck!

**Explanation:**

It is given that,

Mass of the tennis ball,

Initial speed of tennis ball,

Mass of ball,

Initial speed of ball,

In case of elastic collision, the momentum remains conserved. The momentum equation is given by :

are final speed of tennis ball and the ball respectively.

..............(1)

We know that the coefficient of restitution is equal to 1. It is given by :

.................(2)

On solving equation (1) and (2) to find the values of velocities after collision.

**So, the speed of both balls are 5.28 m/s and 3 m/s respectively. Hence, this is the required solution.**

**Answer and Explanation:**

- Since we're discussing shots, the significant thing is the way the energy is changed over as there is deceleration of the bullet to a halt when it hits something.

- Kinetic Energy is relative to mass times speed squared, so in reality, the 2 cases given have practically indistinguishable Kinetic energy. The measure of energy is authoritative, so the two cases will do generally a similar harm given, obviously we look at situations when all the kinetic energy is spent.

- One contrast that will be effectively obvious is that the weapon in the case of heavy bullet will recoil more.
- One can consider energy assimilation as force times separation distance, and energy ingestion as a product of force and time.
- Henceforth, the heavier yet more slow bullet with a similar energy will venture to every part of a similar separation in the engrossing material, but since of bigger force, will take a more drawn out time doing it.
- It will along these lines, additionally, give a more noteworthy "kick" to the object that absorbs.

**Answer: Length axis f= 114.3 Hz, Width axis f=228.67 Hz**

**Explanation:**

We are given that,

Length of tub= 1.5 m

Width of tub= 0.75 m

Sound speed= 343 m/s

Now, we are also given shower is closed.

So, frequency is given as:

f=

For length axis

Put v= 343 m/s, m=1 and L=1.5 m

f= 1 *

**f= 114.3 Hz**

For next resonant frequency, m=2

f= 2*

**f= 228.67**

For width axis

Put v= 343 m/s, m=1 and L= 0.75 m

f= 1*

**f= 228.67 Hz**

For next frequency, m=2

f= 2*

**f= 457.34 Hz**

The answer is A I’m pretty sure it is

Answer:

the second derivative of y with respect to time gives the transverse acceleration of an element on a string as a wave moves along an x axis along the string

Explanation:

This is because the transverse wave movement of particles take place in direction 90° to direction of movement of the wave (x) itself, so second derivative of y with respect to time (t)is what will be required
