Answer:
The strength of magnetic field is 0.25 T
Explanation:
Time period sec
Mass of proton kg
Charge of proton C
Here proton moves in circular path
Velocity of proton is given by,
Put the value of velocity in above equation,
Now magnetic field is given by,
T
Therefore, the strength of magnetic field is 0.25 T
<u>for instance, steel has a higher thermal conductivity than plastic. Hence, the steel plate gives away heat to the ice block faster than a plastic block does. As a result, ice melts faster on a steel plate than on a plastic one. Faster an object draws heat, the colder it feels.</u>
Answer:
0.00000833 Pa
0.0000166 Pa
Explanation:
I = Light intensity = 2500 W/m²
c = Speed of light =
Pressure is given by
The pressure is 0.00000833 Pa
In atm
The pressure is
For total reflection
The pressure is 0.0000166 Pa
In atm
The pressure is
This is just a simple problem finding out the outer surface charge, the inner surface charge and the net charge. Net charge by definition means the difference between two charges. In this case, the formula that is applicable here is outer surface charge = total net charge - inner cavity surface charge. Since we are given already with the net charge equal to 12.0 x10-6 C and the inner charge magnituude f 3.7 x10-6 C, the the total charge must be outer charge is +10x10(-6)) - (-3.0x10(-6)) = +1.3x10(-5) C.
Charges are measured in coloumbs and most likely exist on surfaces of entities like particles, walls etc.
A star may form a black hole
once is true. After the marked supernova explosion, the star shrinks because it
sheds away the gaseous layers of the star. And especially if the star is large,
it will form into a black hole.
