Answer:
0.83m/s forward
Explanation:
Velocity is the displacement divided by time.
Velocity =
Displacement is the distance moved in a specific direction;
→ 6meters forward
← 3meters backwards
→ 7 meters forward
Net displacement =7m + 3m = 10m forward
So;
Velocity = = 0.83m/s forward
Answer:
so separation between slit is 0.12 mm
Explanation:
given data
slit wide = 0.020 mm
wavelength λ = 589.6 nm
fringe pattern n = 11
to find out
separation between the slits
solution
we know that for maxima we can say
d sinθ = m × λ .........1
and m is mth order maxima
and for central maxima
number of bright fringe is here
N = 2m -1
11 = 2m - 1
m = 6
so here number of maxima on either side of central maxima will be m-1
that is = 5
because we know 6th maxima will be minimized by minima
so
condition for minima is
a sin(θ) = n × λ
now for 1st minima
a sin(θ) = λ
and
= m
d = ma
d = 6 × 0.02
d = 0.12 mm
so separation between slit is 0.12 mm
Define and measure the speed
choose this
heliocentric theory = Ptolomeu
radioactivity = Becquerel
reflecting telescope - Newton (not sure)
Answer:
The time rate of change of the electric field between the plates is
Explanation:
From the question we are told that
The radius is
The distance of separation is
The current is
Generally the electric field generated is mathematically represented as
Where is the permitivity of free space with a value
So the time rate of change of the electric field between the plates is mathematically represented as
But
So
substituting values
Its a, metal is a good conductor of heat so yea
Hope this helps :)
