Explanation:
It is known that relation between kinetic energy and temperature is as follows.

Hence, kinetic energy is directly proportional to temperature.
Thermal energy is defined as the energy present within the molecules of an object due to the motion of particles. Basically, thermal energy is internal energy of an object.
Thus, we can conclude that:
- Temperature and kinetic energy are directly proportional.
- Heat is a measure of thermal energy.
- Temperature is proportional to the total kinetic energy.
Answer:ring closure result in fewer molecules
Explanation:
entropy is a measure of the amount of disorderliness in a system.
Therefore, the connection causes orderliness in the ring closure
Answer:

Explanation:
An object is at rest along a slope if the net force acting on it is zero. The equation of the forces along the direction parallel to the slope is:
(1)
where
is the component of the weight parallel to the slope, with m being the mass of the object, g the acceleration of gravity,
the angle of the slope
is the frictional force, with
being the coefficient of friction and R the normal reaction of the incline
The equation of the forces along the direction perpendicular to the slope is

where
R is the normal reaction
is the component of the weight perpendicular to the slope
Solving for R,

And substituting into (1)

Re-arranging the equation,

This the condition at which the equilibrium holds: when the tangent of the angle becomes larger than the value of
, the force of friction is no longer able to balance the component of the weight parallel to the slope, and so the object starts sliding down.
Answer:
The length of a tube and number of rounds are 0.848 m and
.
Explanation:
Given that,
Wavelength

We need to calculate the length
Using formula of wavelength
Laser tube behave like closed pipe



Distance traveled by pulse of light in one back and fourth trip



We need to calculate the time
Using formula for time



We need to calculate the number of round
Using formula of number of round



Hence, The length of a tube and number of rounds are 0.848 m and
.
Answer:

Explanation:
We are given that
Initial velocity=u=18ft/s
Final velocity,v=38ft/s
Time=t=3 s
We have to find the average acceleration over that 3 s period.
We know that
Average acceleration,a=
Using the formula
Average acceleration,a=
Average acceleration,a=
Average acceleration,a=
Hence, the average acceleration=
