Which image illustrates the bending of a wave as it passes into a new
Material?
A. A
B. B
C. C
D. D
Answers
Answer:
Option B.
Explanation:
The bending of a wave when it reaches the interface separating two media is called refraction of light.
In figure B, the wave initially in medium 1. Then it reaches the interface. After that it bends. It means the bending of light occurs in this case.
Hence, the correct option is (B).

What kind of waves can cause the most damage on the earth's surface?
Answers
Answer:
Surface waves, in contrast to body waves can only move along the surface. They arrive after the main P and S waves and are confined to the outer layers of the Earth. They cause the most surface destruction. Earthquake surface waves are divided into two different categories: Love and Rayleigh.

At the end of the hill Alex and Jason are holing a crash pad to stop the dynamic duo from falling off the cliff. If the riders have a combined mass of 200 kg and an acceleration of 30 m/s^2, what Force will they crash the mattress with? Use the correct Force for full credit.
Answers
Answer:
They will crash with the force of 6,000N
Explanation:
Force is equal to mass time acceleration. When we multiply 200 kg, the mass, and 30 m/s2, the acceleration, the answer is 6,000.

Answers
Global climate change is a change in the atmosphere that occurs all over the planet simultaneously. Although these changes have occurred in certain periods in a natural way, we are currently facing global climatic changes caused by human activities, which have inconsequentially modified the natural harmony of climatic conditions.
The climate change we are currently experiencing refers to global warming, where the earth's temperature is increasing on an alarming and worrying scale. Global warming has caused the melting of the polar ice caps, harmed marine life, increased the surface temperature of the oceans, caused droughts and floods, in addition to promoting an abnormal and harmful sensation to living beings.
These changes are the result of the constant use of fossil fuels, deforestation, pollution and other human activities that have degraded nature and the atmosphere. This is because these activities, mainly the use of fossil fuels, promote a large production of carbon dioxide, which, when released into the atmosphere, causes holes in the ozone layer that protects our planet from the sun's rays. With the depletion of the ozone layer, the planet is left unprotected and receives sun rays at harmful intensities.
Therefore, we can conclude that the global climate changes that we are experiencing are the consequences of our own actions and that is why it is our responsibility to repair the damage caused by global warming and to promote measures that reduce it.
Two long straight parallel lines, #1 and #2, carry uniform positive linear charge densities. The charge density on line #2 is twice as great as the charge density on line #1. The locus of points where the electric field due to these lines is zero is
along a line between the lines closer to line #2 than line #1.
at a point midway between the lines.
along a line between the lines closer to line #1 than line #2.
along a line perpendicular to lines #1 and #2.
Answers
Answer:
The locus of points where the electric field due to these lines is zero is;
Along the line between the lines closer to line#1 than line #2
Explanation:
The charges on the parallel lines #1 and #2 = Positive linear charge
The charge density on line #2, λ₂ = 2 × The charge density on line #1, λ₁
Therefore, we have;
λ₂ = 2 × λ₁
Electric field strength, E, is given as follows;
[tex]E = \dfrac{\lambda}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]
Therefore;
[tex]E_1 = \dfrac{\lambda_1}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]
[tex]E_2 = \dfrac{\lambda_2}{2\cdot \pi\cdot \epsilon_0\cdot d} = 2 \times\dfrac{\lambda_1}{2\cdot \pi\cdot \epsilon_0\cdot d}[/tex]
E₂ = 2·E₁
E₂/2 = E₁
E₂/(2·d) = E₁/d
The strength of the electric field at a given distance from line #2 is 2 times the strength of the electric field from line #1 at the same distance
Therefore the strength of the electric field will be the same at a point twice the distance from line #2 than from line #1 which is a point closer to line #1 than line #2.

NO LINKS PLEASE JUST STRAIGHT UP ANSWER. Two asteroids each have mass of 1.41 x 10^14 kg. The strength of the gravitational force between them is 1,030 N. Calculate the distance between the asteroids.
Answers
Answer:
3.59x10^7
Explanation:
Khan
The distance between the two asteroids of mass 1.41 × 10¹⁴ kg and gravitational force of 1030 N is 3.588 × 10⁷m.
What is Gravitational force?The gravitational force can be defined as the force of attraction or the attractive force which attracts all the physical forms which have some mass. It is by far the weakest recognized natural force on this planet.
Given mass of each of the two asteroids is 1.41 × 10¹⁴ kg
Gravitational force = 1030 N
Let the distance between the two asteroids be 'd'
We know, F = (G × m₁ × m₂) /d²
F = G × m²/ d² (mass of asteroids is same)
d = ([tex]\sqrt{G/F}[/tex]) M
Therefore, d = (√6.67 × 10⁻¹¹/ 1030)× 1.41 × 10¹⁴ kg
d = 3.588 × 10⁷m
Therefore, the distance between the two asteroids is 3.588 × 10⁷m.

Which statement is false?
A) Doubling the mass halves the acceleration
B) Doubling the force doubles to acceleration
C) Doubling the mass doubles the acceleration
Answers
Statement C is false. Doubling the mass doubles the acceleration is the wrong statement.
What is force?Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body.
Force is defined as the product of mass and acceleration. Its unit is Newton.
Mathematically, the force is;
[tex]\rm F= ma[/tex]
If force is constant, the mass is inversely proportional to the acceleration. If the mass is double in that condition, acceleration is halved.
Doubling the mass doubles the acceleration is the wrong statement.
Hence, statement C is false

A heat pump receives heat from a lake that has an average winter time temperature of 6o C and supplies heat into a house having an average temperature of 25o C. (a) If the house loses heat to the atmosphere at the rate of 60,000 kJ/h, determine the minimum power supplied to the heat pump (in kW) that can maintain the interior temperature of the house at 25o C. (b) Suppose the heat pump absorbs energy from the ground (10o C) instead of the lake, Calculate the minimum power (in kW) required for the heat pump.
Answers
Answer:
Explanation:
60000 kJ / h = 60000 x 1000 / (60 x 60 )
= 16667 J /s
a)
[tex]\frac{Q_H}{W} =\frac{T_H}{T_H-T_C}[/tex]
where [tex]Q_H[/tex] and [tex]W[/tex] are heat supplied and heat given from outside source .
Here [tex]Q_H[/tex] = 16667 J/s
[tex]\frac{T_H}{T_H-T_C}=\frac{298}{298-279}[/tex]
= 15.684
[tex]Q_H = 16667 J/s[/tex]
16667 / W = 15.684
W= minimum power supplied = 1062.7 W.
b )
If [tex]T_C=283K[/tex]
[tex]\frac{T_H}{T_H-T_C}=\frac{298}{298-283}[/tex]
=19.87
[tex]\frac{Q_H}{W} = 19.87[/tex]
[tex]W=\frac{Q_H}{19.87}[/tex]
[tex]W=\frac{16667}{19.87}[/tex]
= 838.8 W .

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this? The function of these bones is the same in all animals They live in similar environments They have a common ancestor All organisms resemble humans
Answers
Answer:
They have a common ancestor
Explanation:
Similar arm bones are present in different types of animals as mentioned which are humans, birds, whales and lizards and the reason is that all of them had the same ancestors and eventually the species evolved into present day forms.
Other options are wrong because.
1. Function is these bones obviously are not same as whales have no arms like humans or birds.
2. They do not live in same environment as whales are in oceans and birds are in airborne whereas humans and lizards are land occupying.
3. All animals are different from each other and do not resemble humans.
Therefore the correct answer is that their ancestors were common.
