Answer:
In the case of an electric bulb, the electrical energy is converted to light and heat. The amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form).

Answer:
The correct option is:
B) Kinetic Energy
Explanation:
We know that if a body is placed at a certain height, it possesses Potential Energy, which is represented by 'mgh'. In this case, when the skydiver is present in the plane, before jumping, he has potential energy as he is at height 'h'.
As Kinetic energy is given as '(1/2)mv²' dependent on velocity of the object, when the skydiver jumps of the plane, his height starts decreasing, which decreases his Potential Energy. As energy can neither be created or destroyed, but is converted to one form or another, all this Potential energy starts to convert into Kinetic energy. As Potential Energy decreases with distance, Kinetic energy increases. Hence, line B represents Kinetic Energy.
That would be c. :) :) :)
Answer:
From the given options, the option (D) is correct. Because Al is the aluminium which is located in period 3 of the periodic table.
Explanation:
We know that the 3rd period contains 8 elements which are as follows:
- sodium
- magnesium
- aluminium
- silicon
- phosphorus
- sulfur
- chlorine, and
- argon
The sodium and magnesium, the first 2 elements, are members of the s-block of the periodic table, while the rest of the members are the elements of the p-block.
Thus, from the given options, the option (D) is correct. Because Al is the aluminium which is located in period 3 of the periodic table.
