The answer would be stage of<span> conversion of Hydrogen to Helium.
At the end of this phase, the helium content of the suns will have the popping effect where more and more helium is now on the core resulting to higher temp and density as helium converted from hydrogen is much heavier.</span>
Answer:
Final velocity of ball = 20 m/s
Explanation:
Given:
Height when ball released = 20meter
Find;
Time taken to fall
Final velocity of ball
Computation:
Initial velocity of ball = 0 m/s
Acceleration due to gravity = 10 m/s²
Using equation of motion;
S = ut + (1/2)(g)(t²)
20 = (0)(t) + (1/2)(10)(t²)
20 = 5(t²)
(t²) = 20 / 5
(t²) = 4
Time taken to fall = 2 second
V = u + at
V = 0 + (10)(2)
Final velocity of ball = 20 m/s
Answer:
Explanation:
According to ohm's law
The current flowing through the wire is directly proportional to the potential difference applied across its ends , provided the temperature and other physical conditions of the wire like stresses and strains remains constant .
Answer: Option (a) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness present in a substance. This means that more randomly the atoms in a substance are moving more will be entropy of the substance.
Entropy of a substance increases with increase in temperature.
For example, when a piece of wood is burned then its molecules will gain kinetic energy and hence, they start to move randomly from one place to another.
As a result, there will occur an increase in its entropy.
Thus, we can conclude that when a piece of wood is burned then its entropy increases.
Answer:
Mike will receive an electric shock
Explanation:
Human body is a conductor of electricity. When lightning strikes rod and give it negative charge, the rod will dissipate its charge as soon as it comes in contact with earth via conduting material. Mike will receive a severe electric shock as negatice charge pass through his body to other rod and to the ground.His body will feel numb. He may also get unconscious.
