gaining thermal energy in form of heat

Explanation:

When the thermal energy of a matter is increasing, it will directly increase the kinetic energy of the matter.

Temperature changes causes the average kinetic energy of molecules to increase or decrease.
If the kinetic energies of particles are increasing, the temperature must have been on rise.
Increase in temperature causes molecules to start vibrating and moving about.
The gain more energy that helps them to move away from their original position

What is the fundamental frequency (in Hz) of a 0.632 m long tube, open at both ends, on a day when the speed of sound is 344 m/s

Greeley [361]

Answer:

$f=272.15Hz$

Explanation:

Given data

Length of tube L=0.632 m

Speed of sound v=344 m/s

To find

Fundamental frequency f

Solution

The fundamental frequency of the tube can be given as:

$f=\frac{v}{2L}\\ f=\frac{344m/s}{2(0.632m)}\\ f=272.15Hz$

In your own words, explain why sinkholes are very common in Florida. List one use of sinkholes in Florida.

melamori03 [73]

Florida's peninsula is made up of porous carbonate rocks such as limestone When the dirt, clay or sand gets too heavy for the limestone roof, it can break and form a sinkhole. Sinkholes are caused naturally.

dont use my words put this in your own hope it helps you understand it better

A machine that operates a ride at the fair requires 2500 J to lift a 294 N child 5.0 m. What is the efficiency of this machine?

NeX [460]

Answer:

η = 58.8%

Explanation:

Work is defined as the force applied by the distance traveled by the body.

$W =F*d$

where:

W = work [J] (units of joules)

F = force = 294 [N]

d = distance = 5 [m]

$W = 294*5\\W = 1470 [J]\\$

Efficiency is defined as the energy required to perform an activity in relation to the energy actually added to perform some activity. This can be better understood by means of the following equation.

$efficiency = W_{done}/W_{required}\\efficiency = 1470/2500\\efficiency = 0.588 = 58.8%$
