Answer:
Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.
Explanation:
The distance 
from the central band to the first bright band is given by
where 
is the wavelength of light (or any particle), 
is the distance to the screen, and 
is the slit separation.
From this equation we see that, by increasing the wavelength , increasing the distance from the screen , and decreasing the slit separation , we increase the distance between the first bright band and the central band.
Therefore, the 2nd choice "<em>Decrease the slit separation, increase the distance of the screen from the slits, and increase the wavelength.</em>" is correct.
Answer:
μk = (Vf - Vc)/(T×g)
Explanation:
Given
Vi = initial velocity of the car
Vf = final velocity of the car
T = Time of application of brakes
g = acceleration due to gravity (known constant)
Let the mass of the car be Mc
Assuming only kinetic frictional force acts on the car as the driver applies the brakes,
The n from Newtown's second law of motion.
Fk = Mc×a
Fk = μk×Mc×g
a = (Vf - Vc)/T
Equating both preceding equation.
μk×Mc×g = Mc × (Vf - Vc)/T
Mc cancels out.
μk = (Vf - Vc)/(T×g)
Answer:
voltage across = 1.6 V
Explanation:
given data
resistance R = 57.61 Ω
capacitance c = 13.13 mF = 13.13 ×
F
inductance L = 196.03 mH = 0.19603 H
fixed rms output Vrms = 23.86 V
to find out
voltage across circuit
solution
we know resonant frequency that is
resonant frequency = 1 / ( 2π√(LC)
put the value
resonant frequency = 1 / ( 2π√(0.19603×13.13 ×)
resonant frequency f = 3.1370 HZ
so current will be at this resonant is
current = Vrms / R
current = 23.86 / 57.61
current = 0.4141 A
and
so voltage across will be
voltage across = current / ( 2π f C )
voltage across = 0.4141 / ( 2π ( 3.1370) 13.13 × )
voltage across = 1.6 V
If it’s not moving then it doesn’t have acceleration… right? So uh 0
5m
Explanation:
Given parameters:
Energy = 35J
Force on object = 7N
Unknown:
Distance moved = ?
Solution:
The energy on the car will cause the car to do work . When work is done, a force moves a body in particular distance. We can see that energy and force are related:
Energy = force x distance
Distance = 
Inputting the parameters:
Distance = 
= 5m
