Answer:
A the force was in their direction
A) the pump removes air from the enclosure. foam absorbs vibrations from the clock
b) result is that as the air is taken out by pump, the sound of alarm reduces and eventually becomes zero. so, you cant hear the alarm ringing.
c) conclusion is that sound cant travel in vaccum and it requires a medium to travel.
Thermal energy can be defined as specific thermodynamic quantities as a part of energy transfer such as heat, which is a form of thermal energy flowing from hotter to colder objects. Temperature is a physical property of an object which specify whether the subject is hot or cold.
<u>Explanation:</u>
Difference between thermal energy, temperature and heat
<u>Thermal Energy</u>
Thermal energy is the total kinetic energy of molecules bundled up in the object. This energy is the heat exerted by the object which forms its temperature.
<u>Temperature</u>
In technical terms, temperature is the average kinetic energies measurement of molecules and atoms, present in an object. Simply, we can say, temperature defines how hot or how cold is a substance. Temperature relies on the kinetic energy of particles.
<u>Heat</u>
Transfer of thermal energy from a hotter to colder objects. Heat is different from temperature. Temperature is the mark to define how hot a substance is whereas, heat is the flow of thermal energy.
Answer:
Explanation:
Read forces directly from the graph.
Read displacements directly from the graph.
Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.
Red: The red parts will stay the same
The blue parts will turn black - there is no red in blue
The white parts will turn red - there is red in white
Blue: The blue parts will stay the same
The red parts will turn black - there is no blue in red
The white parts will turn blue - there is blue in white
