Answer:
The capacitance is 11 F for half and fully charged capacitor.
Explanation:
Capacitance of capacitor is given by the expression
Where ε is the vacuum permittivity, A is the area of plates and d is the separation between plates.
So capacitance does not depend upon charge and potential. So capacitance fully and half charged capacitors are same.
Here the capacitance is 11 F for half and fully charged capacitor.
Answer:
KE=1.366×10⁻¹⁶J or
KE=854ev
Explanation:
single slit diffraction pattern occur where sinФ=mλ/a for m=±1,±2,±3,.......
Here λ is wavelength
The spacing between successive minima is then
Δy=
Δy=λ(L/a)
as given Δy=2.10cm, L=25cm and a=0.500nm
so for λ
λ=Δy(a/L)
λ=4.2×10⁻¹¹m
The momentum of one of these electrons is then
p=h/λ
Assuming the electron is non-relativistic, its kinetic energy is
Convert joules into electronvolt we get
KE=854ev
Answer:
The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.
Explanation:
Weight of the object on the surface of Earth, W = 245 N
On the surface of Earth, acceleration due to gravity, g = 10 m/s²
Weight of an object is given by :
W = mg
m is mass
So, the mass of the object is 24.5 kg
Acceleration due to gravity on Mars, g' = 3.72 m/s²
Weight of the object on Mars,
W' =mg'
W' = 24.5 kg × 3.72 m/s²
= 91.14 N
So, the weight of the object on Mars is 91.14 N.
