Explanation:
Let
is the mass of proton. It is moving in a circular path perpendicular to a magnetic field of magnitude B.
The magnetic force is balanced by the centripetal force acting on the proton as :

r is the radius of path,

Time period is given by :


Frequency of proton is given by :

The wavelength of radiation is given by :


So, the wavelength of radiation produced by a proton is
. Hence, this is the required solution.
Answer:
a) Temperatura, b) Temperature, c) Constant
, d) None of these
, e) Gibbs enthalpy and free energy (G)
Explanation:
a) the expression for ideal gases is PV = nRT
Temperature
b) The internal energy is E = K T
Temperature
c) S = ΔQ/T
In an isolated system ΔQ is zero, entropy is constant
Constant
d) all parameters change when changing status
None of these
e) Gibbs enthalpy and free energy
Answer:
Explanation:
As it moves along, the paper is given a strong negative electrical charge by another corona wire. When the paper moves near the drum, its negative charge attracts the positively charged toner particles away from the drum.
Answer:
Current in the hair dryer will be equal to 15 A
Explanation:
We have given that household is operated at 110 volt
So potential difference V =110 volt
Power drawn by hairdryer is P = 1650 watt
We have to find the current in the hair dryer
We know that power is given as P = VI, here V is potential difference and I is current
So 
I = 15 A
So current in the hair dryer will be equal to 15 A
The acceleration of gravity on Earth is 9.8 m/s². That means that
an object falling under the influence of gravity will move 9.8 m/s
faster than it was moving a second earlier.
Falling from rest, it will be moving 9.8 m/s after the first second,
and 19.6 m/s after the 2nd second.
The height from which it fell doesn't matter.
