Answer:
In order to create a new element you have to change the number of protons in a nucleus.
Answer:
option C
Explanation:
When the baseball is hit high and far it has some horizontal velocity at the highest point so option an i.e. velocity at the highest point is eliminated.
the baseball act as a projectile at the highest point so, there is always downward acceleration acting on the body. so, option e and d is eliminated.
At the highest point, the vertical velocity is zero and neglecting the air resistance we can say that the velocity of the body is slowest.
Hence, the correct answer is option C
Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
Answer:
50.76°
Explanation:
To find the angle between the two polarizers, you take into account that each polarizing sheet reduces the intensity of the light. Then, you have:
After the unpolarized light crosses the first polarizer:
After light crosses the second polarizer:
θ: angle between the two polarizing sheets
When the light emerges from the second polarizer the intensity of the light is 0.2 times the initial intensity, then you have:
hence, the angle between the polarizing sheets is 50.76°
