Answer:
Explanation:
Given
mass of block
Force
Force is applied at an angle of
Displacement of block
coefficient of kinetic friction
Friction force acting on block
where N=Normal reaction
Work done by friction
Negative sign indicates that displacement is against the direction of force.
Answer: B = 1.69 T
Explanation: Given that the
Electron velocity V = 7.4 × 10^5 m/s
Force F = - 2 × 10^-13 N
Charge q = -1.602 x 10-19 C.
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ .
Since the electron is moving perpendicular to a magnetic field,
sin θ = sin 90 = 1, therefore
- 2 × 10^-13 = - 1.602×10^-19 × 7.4×10^5B
B = -2×10^-13/1.2×10^-13
B = 1.68708T
B = 1.69 T
Answer:
it increases by a factor 1.07
Explanation:
The peak wavelength of an object is given by Wien's displacement law:
(1)
where
b is the Wien's displacement constant
T is the temperature (in Kelvins) of the object
given the relationship between frequency and wavelength of an electromagnetic wave:
where c is the speed of light, we can rewrite (1) as
So the peak frequency is directly proportional to the temperature in Kelvin.
In this problem, the temperature of the object changes from
to
so the peak frequency changes by a factor
