True
It is True I took the test
Answer: A
Hope this help you!!
A) Geothermal
B) Hydroelectric
C)Biomass
D) Wind
I assume this is the four options you had, correct?
i think that biomass is the only one that would release the greenhouse gases. I once heard, it may not be true, that biomass has more co2 released than coal.
What is the kinetic energy of the system after the collision?

How this is calculated?
Given:
Initial speed=
mass of rod=M
Let, Initial kinetic energy =
Final kinetic energy=
Moment of inertia =I
What is the moment of inertia?

What is the angular momentum?
By conservation of angular momentum,


We know that, the final kinetic energy is given by,

What is the kinetic energy?
- In physics, the kinetic energy of an object is the energy that it possesses due to its motion.
- It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
- Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Answer:
λ = a
Explanation:
This is a diffraction exercise that is described by the expression
a sin θ = m λ
sin θ = m λ/ a
the first zero of the diffraction occurs for m = 1
sin θ = λ / a
angles are generally very small and are measured in radians
sin θ = θ = y / x
we substitute
the width of the central maximum is twice the distance to zero
w = 2y
in the exercise indicate that this width is equal to twice the distance to the screen (2x)
W = 2x
2y = 2x
we substitute
1 = λ/ a
λ = a
we see that the width of the slit is equal to the wavelength used.
