Explanation:
Transparent objects do not form shadows. The light passes completely from the transparent objects thus these objects will not form shadow. ... In such objects, the light gets refracted thus, such objects forms shadow. The refraction is also the reason why we can see such objects.
Answer:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

Answer:
4820.9 J of work is done on the flight bag.
Explanation:
Given:
Force acting on the bag is,
Displacement of the bag caused by the force is,
Angle between the direction of force and direction of displacement caused is,
Now, the formula to calculate work done on a body by a force 'F' causing displacement 'S' at an angle between the two vectors is given as:
Plug in the given values and solve for work done 'W'. This gives,
Therefore, the work done on the flight bag is 4820.9 J.
Geothermal energy.
Electromagnetic energy originates at the sun (think UV rays; they are part of the electromagnetic spectrum). Electrical energy technically can be anywhere, as long as there are positive and negative charges. Mechanical energy is like a generator or an engine; there is always something working to get things done/made.
I hope this answer and these explanations helped!
