Biomass is a modern name for the ancient technology of burning plant or animal material for energy production, or in various industrial processes as raw substance for a range of products.
U can try to use capacitor , the value of capacitor depends on circuit
ripple factors signifies the ac components, by def its ratio of rms value of ac component to value of dc component
so in order to reduce use of a capacitor which denies the sudden changes in voltage, which is the charracteristic of Ac signals
hope this helps
Answer:
v = 0.22 c and wavelength is decrease so galaxy A is move away from stationary galaxy
v = 0.095 c and wavelength is increase so galaxy B come toward stationary galaxy
Explanation:
Given data
found = 500 nm
shifted A = 400 nm
shifted B = 550 nm
to find out
How fast and in what direction is galaxy
solution
we use here formula that is
(λ) shifted = √(1-β / 1+β) (λ)found
1-β / 1+β = (4/5)² ..................1
1-β / 1+β = 16 / 25
β = 0.22
v/c = 0.22
v = 0.22 c
here wavelength is decrease so galaxy A is move away from stationary galaxy
and
here according to equation 1
and we use shifted 550 nm
so
1-β / 1+β = (5.5/5)²
1-β / 1+β = 30.25 / 25
β = 0.095
so v/c = 0.095
v = 0.095 c
here wavelength is increase so galaxy B come toward stationary galaxy
Answer:
option c is correct
Explanation:
we know that time rate of change of velocity is called acceleration
so a=v/t
a=12/4
a=3m/s²
Answer:
Explanation:
The momentum will be conserved .
M₁ V₁ =M₂V₂
2.3 x 15 = 75 x V
V = .46 m/s
velocity of astronaut will be 0.46 m/s after the throw of wrench .
Impulse = change in momentum
= 75 x .46 - 0
= 34.5 kg m/s
Impulse = force x time
34.5 = force x .12
force = 34.5 / .12
= 287.5 N
average acceleration
= force / mass
= 287.5 / 75
= 3.83 m /s²
