<h2>Answer:</h2>
No, interference patterns will not be observed as the two sources of light are neither monochromatic neither coherent and therefore interference of light will not form total reinforcement or total cancellation at any point
Answer: 1.77kg
Explanation:
Using the concept or hooke's law, the force (F) applied to a string is directly proportional its extension (e)
F=ke
K is the elastic constant
If the mass applied initially is 0.59kg i.e 5.9N force, we have
5.9=ke... (1)
If a second block is attached let's say 'm', its force will be 10m, and the extension will become 3e
10m = 3ke ... (2)
Dividing eqn 1 by 2,
5.9/10m = ke/3ke
5.9/10m = 1/3
10m = 5.9×3
m = 5.9×3/10
m = 1.77kg
Let be the distance between the two houses. Considering the formula
where is the distance, is the velocity and is the time, we can solve it for the time to get
So, the two trips take the following time:
To get the average speed, we need to consider the two trips together. Globally, the person traveled a distance of , and the global time is the sum of the two times. We have
Answer:
Inductance, L = 0.0212 Henries
Explanation:
It is given that,
Number of turns, N = 17
Current through the coil, I = 4 A
The total flux enclosed by the one turn of the coil,
The relation between the self inductance and the magnetic flux is given by :
L = 0.0212 Henries
So, the inductance of the coil is 0.0212 Henries. Hence, this is the required solution.
Answer: Our body contains chemical potential energy from food we have eaten.
This chemical potential energy is transformed into the kinetic energy of our hands and arms as we rub our hands together.
As our hands move past each other and rub against each other, friction allows the kinetic energy to be transformed into thermal energy on the surface of our hands.
Explanation:
It is true that our food contains chemical bonds and these bonds have potential energy stored. So, when we eat food then our body acquires chemical potential energy.
When we rub our hands and arms then they form kinetic energy as atoms present within the skin of our hands come into motion. This rubbing of hands leads to the formation of heat which means thermal energy is being generated.
Thus, we can conclude that our body contains chemical potential energy from food we have eaten.
This chemical potential energy is transformed into the kinetic energy of our hands and arms as we rub our hands together.
As our hands move past each other and rub against each other, friction allows the kinetic energy to be transformed into thermal energy on the surface of our hands.
