A scientist is designing a device that will mimic Earth's atmosphere by
blocking high-energy waves from the Sun. Pick three high-energy waves
that the device should be able to block?
Answer:
1. Ultraviolet light (UV)
2. X-rays
3. Gamma-rays
Explanation:
Though there are different types of energy or electromagnetic waves with varying wavelengths, including the likes of Gamma X-rays, ultraviolet light, visible light, infrared radiation, and microwave radiation.
What is more certain is that the atmosphere blocked the high-energy waves from getting to the earth surface or biosphere such as Ultraviolet light (UV), X-rays and Gamma-rays
A large spool in an electrician's workshop has 65 m of insulation-coated wire coiled around it. When the electrician connects a battery to the ends of the spooled wire, the resulting current is 1.8 A. Some weeks later, after cutting off various lengths of wire for use in repairs, the electrician finds that the spooled wire carries a 2.9-A current when the same battery is connected to it. What is the length of wire remaining on the spool
Answer:
[tex]40.34\ \text{m}[/tex]
Explanation:
[tex]L_1[/tex] = Length of wire = 65 m
[tex]I_1[/tex] = Initial current = 1.8 A
[tex]I_2[/tex] = Final current = 2.9 A
We know
[tex]R\propto \dfrac{1}{I}[/tex]
and
[tex]R\propto L[/tex]
[tex]\dfrac{V}{I}\propto L\\\Rightarrow L\propto \dfrac{1}{I}[/tex]
so
[tex]\dfrac{L_2}{L_1}=\dfrac{I_1}{I_2}\\\Rightarrow L_2=\dfrac{I_1}{I_2}L_1\\\Rightarrow L_2=\dfrac{1.8}{2.9}\times 65\\\Rightarrow L_2=40.34\ \text{m}[/tex]
The length of the wire remaining on the spool is [tex]40.34\ \text{m}[/tex].

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.

Need help please help.
Answer:
below
Explanation:
that is the procedure above
Adding energy (_____) causes the temperature to _____ OR the phase to change. Removing energy (flows______) causes the temperature to ___ OR the phase to change. When the phase changes, the temperature ______ because the ______ are breaking or forming. When energy is added to a solid, a liquid, or a gas, but the temperature is increasing (no phase change), the molecules are moving ______. A phase change will start to occur when the kinetic energy of the particles is ______ the attractive forces between the particles.

A chocolate bar has nutritional energy content of 100KJ. If an 50kg mountain climber eats this chocolate bar and converts it all to potential energy. What altitude(height) can she climb on a mountain using this energy? Consider g=10m/s^2
Answer:
h = 200 m
Explanation:
The energy content of the chocolate is completely converted to the potential energy of the climber. Therefore:
[tex]Energy\ of\ Chocolate = Potential\ Energy\\Energy\ of\ Chocolate = mgh[/tex]
where,
m = mass of climber = 50 kg
Energy of Chocolate = 100 KJ = 100000 J
g = acceleration due to gravity = 10 m/s²
h = height = ?
Therefore,
[tex]100000\ J = (50\ kg)(10\ m/s^2)h\\\\h = \frac{100000\ J}{500\ N}[/tex]
h = 200 m

If 10.0 J of work are required to transfer 2.00 coulombs of
charge from point X to point Y in an electric field, what is the
difference in potential between these two points?
Answer: 5V
Explanation: because 2 goes into 10, five times. Also I know it’s correct cuz I got it right in my quiz
The difference in potential between these two points is 5 V.
Electric potential between the two points
The electric potential between two points is the work done in taking a unit postive charge from one point to another.
The difference in potential between these two points is calculated as follows;
W = qV
V = W/q
V = 10/2
V = 5 V
Thus, the difference in potential between these two points is 5 V.

Answer:
Newton's Third Law
Explanation:
When one object exerts a force on another object, the second object exerts a force on the first object that is equal in magnitude, but opposite in direction; for every action, there is an equal, but opposite reaction; called the law of action-reaction.

When trying to simplify and find the equivalent resistance you should first simplify resistors in _ before simplifying those in _
The equivalent resistance for the parallel connected resistance will be
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]
What is resistance?
Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω)
Now if two resistances are connected parallel then the voltage on the resistances will be different and the same current will flow from both resistances.
[tex]V_{eq}=V_1+V_2[/tex]
[tex]I_{eq}R_{eq}=I_1R_1+I_2R_2[/tex]
Since [tex]I_{eq}=I_1=I_2[/tex]
[tex]R_{eq}=R_1+R_2[/tex]
Hence the equivalent resistance for the parallel connected resistance will be
[tex]\dfrac{1}{R_{eq}}=\dfrac{1}{R_1}+\dfrac{1}{R_2}[/tex]
