A person shakes a sealed, insulated bottle containing coffee for a few minutes. What is the change in the temperature of the coffee?.
A person shakes a sealed, insulated bottle containing coffee for a few minutes, then the change in the temperature of the coffee increases slightly.
What happens when insulated bottle with coffee is shaken?The temperature of the coffee increases when insulated bottle is sealed and shaken because the exchange of heat from the surrounding from the thermos bottle is zero. From the first law of thermodynamics, the work done on system is equal to the change in internal energy.
As thermos flask is insulated, therefore no heat energy is added to the system,
Therefore, △Q=0
Work is done by shaking it against viscous force.
Now, △w=−ve
Internal energy , △U=△Q−△w=0−(−△w)
△U=+△w
So, △U=+ve
Hence, temperature of the system increases due to the increase in internal energy.

For motor,
f = 50 Hz
n = 120 * 50 / Pm
For generator,
f = 60 Hz
n = 120 * 60 / Pg
To accomplish the frequency conversion, the speed of the motor and generator must be equal. So,

The study of elastic wave motion through the ground is known as seismology. Seismology of earthquakes is the finest method for investigating the earth's core. A portion of the energy released after an explosion or earthquake is transported through the earth as elastic waves. Stresses increase in the crust as the lithospheric plates of the Earth continue their sluggish motion, particularly close to the plate borders. Compression, tension, and shear stresses increase in the crust until they exceed the resistance of the rock or the friction along an existing fault. Then, an abrupt rock slide along a fault happens. The rocks lurch to their new location in a matter of seconds, and the ground trembles as the stress energy is released. Similar to growing ripples from a pebble thrown in still water, seismic waves propagate outward from the area of the fault that ruptured.

What is zero velocity?
The zero-velocity surface is a notion connected to the N-body gravity problem. It represents a surface that a body with the specified energy cannot traverse because it would have zero velocity there. George William Hill made the initial proclamation about it.

acceleration on both the balls is same
Time to hit the ground is also equal for both the balls.
Here the acceleration is only acceleration due to gravity in vertically downward direction.
No acceleration in horizontal direction as air resistance is neglected.
Both the balls are projected from same height and downward acceleration is same and there is no initial downward velocity ,hence both the balls take same time to hit the the ground.
Time to hit the ground is also equal for both the balls.

a race car traveling at a constant speed of 50 m/s drives around a circular track that is 500 m in diameter. what is the magnitude of the acceleration of the car
The magnitude of the acceleration of the car was 10m/s^2
what is magnitude?
Magnitude is defined in physics as an object's maximal size and direction. Magnitude is utilised in vector and scalar variables as a common factor. Scalar quantities, by definition, are those with only magnitude. Whereas vector quantities have both magnitude and direction.
Magnitude can be used in a variety of contexts. Some of them include
The magnitude of the earthquake
Charge magnitude on an electron
Force magnitude
The magnitude of the displacement
Gravitational force magnitude
acceleration (a)= v^2/r
v=speed
r=radius
d=diameter=500
r=d/2=500/2=250
a= 50^2/250
=10 m/s^2
Therefore the acceleration was found to be 10m/s^2

a spaceship moves at speed 0.5c relative to the earth with its headlight on. what value does an observer on the earth get by measuring the speed of light emitted by spaceship
1.0c. Light will always propagate through a vacuum at the speed of light “c”.
What is the velocity of a light?One universal physical constant that is significant in many branches of physics is the speed of light in a vacuum, typically abbreviated as c.The exact value of the speed of light, c, is 299,792,458 meters per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).The speed at which common matter or energy (and consequently any signal conveying information) can move through space is c, according to the special theory of relativity.Visible light is an example of electromagnetic radiation that moves at the speed of light.Light and other electromagnetic waves appear to propagate instantly for many practical purposes, but their finite speed has noticeable effects for long distances and very sensitive measurements.To learn more about Special theory of relativity. refer,
