Answer:
Explanation:
λ
given λ = 700 nm
a) for first maxima, d*sin(θ) = λ
sin(theta) = λ/d
= 700*10^-9/(0.025*10^-3)
= 0.028
theta θ = sin^-1(0.028)
= 1.60 degrees
b) given R = 1 m,
delta_y = λ*R/d
= 700*10^-9*1/(0.025*10^-3)
= 0.028 m or 2.8 cm
c) for first maxima, d*sin(θ) = λ
sin(θ) = λ/d
= 700*10^-9/(2.5*10^-3)
= 0.00028
theta = sin^-1(0.00028)
= 0.0160 degrees
d) R = 25 mm = 0.025 m
δ_y = λ*R/d
= 700*10^-9*0.025/(2.5*10^-3)
= 7*10^-6 m or 7 micro m
e) No. But the position of maxima and minima will be shifted.
Answer:
the conversion of matter into energy
Explanation:
A nuclear reaction is a reaction in which there is a change in the nuclei of the atoms involved. The two most important examples of nuclear reactions are:
- Nuclear fission: it occurs when a heavy, unstable nucleus breaks apart into two or more lighter nuclei
- Nuclear fusion: it occurs when two lighter nuclei fuse together into a heavier nucleus
In both cases, the total mass of the final products is smaller than the total mass of the initial nuclei: this means that part of the mass of the initial nuclei has been converted into energy, according to Einstein's formula:
where is the variation of mass and c is the speed of light. Since the value of c is very large, we can see from the formula that even a small amount of is able to produce a huge amount of energy, and this is a typical feature of any nuclear reaction.

The procedure is the plan for how you will conduct your experiment.
Explanation:
Answer:
fem = 0
Explanation:
The electromotive force is given by Faraday's law
fem = - d / dt
where \phi _{B} is the flux of the magnetic field
The low magnetic flux is
\phi _{B} = B. A = B A cos θ
substituting
fem - d (B A cos θ) / dt
therefore for an electromotive force to exist there must be a change with respect to the time of
* The magnetic field
* The area waxed by the loop
* the angle between the magnetic field and the normal loop
* Any combination of the above
In this case, as the generator is stopped (inactive), there is no change in the parameters, therefore the electromotive force is zero (fem = 0).
G: V=120v and I=.75amps
U: R=?
S: To fins the resistance of the lightbulb you’d have V divided into I so,
S: 120/.75 = Therefore the resistance is 160ohm
