Answers
Answer:
more
Explanation:
The velocity does not change greatly between Mars and Venus —explained Dong— but Venus's closer proximity to the sun boosts the density by almost a factor of 4.5. This would mean that atmosphere on Mars would be lost even more rapidly than at its current position.
When a substance easily dissolves in a liquid, it has high solubility in that liquid. When a substance does not easily dissolve in a liquid, it has low solubility in that liquid. Solubility of a gas in water describes how well the liquid can "hang on" to gas, instead of releasing it into the air. Based on the results of your experiment, do you think that CO2 has a higher solubility in hot water or cold water? Why?
Answers
Answer:
CO2 has a higher solubility in cold water
Explanation:
The solubility of gases decreases with increasing temperature, the cold water will take up more CO2 and less will be escaping to the air. Furthermore, cold water is denser than warm water, causing it to sink.
What happens to waves near the shore?
Answers
Answer As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom. ... Think of it like driving a car at high speed and then slamming on the breaks. Everything is going to fly to the front.:Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. ... Eventually the bottom of the wave slows drastically and the wave topples over as a breaker. hope this helps have a nice night❤️❤️❤️

A roller coaster has a loop in which the centripetal acceleration equals 9.8m/s2 . Of the tangential speed of the roller coaster cars is 15-7 m/s
Answers
Answer:
25.152mExplanation:
Compete question;
A roller coaster has a loop in which the centripetal acceleration equals 9.8m/s² . If the tangential speed of the roller coaster cars is 15.7 m/s, find its radius.
centripetal acceleration a = v²/r
v is the tangential speed
r is the radius
Given
v = 15.7m/s
a = 9.8m/s²
9.8 = 15.7²/r
9.8r = 15.7²
r = 15.7²/9.8
r = 246.49/9.8
r = 25.152m
Hence the radius of the coaster is 25.152m

Answers
Answer:
So, if a wave hits a mirror at an angle of 36°, it will be reflected at the same angle (36°). ... An incident ray of light hits a plane mirror at an angle and is reflected back off it. The angle of reflection is equal to the angle of incidence. Both angles are measured from the normal.
Explanation:
A ball of mass 12 kg is released from a height of 2.5 m
find the gravitational potential energy of the ball at point A
and when it reach the ground.
then deduce the kinetic energy of the ball once it reach the ground
(use g=10 N/kg) * 5
Answers
Answer:
300 J
Explanation:
From conservation of energy;
Gravitational potential energy at top = Kinetic Energy at bottom
mgh = ½mv²
We are given;
Mass; m = 12 kg.
Height; h = 2.5 m
g = 10 m/s²
Thus;
mgh = 12 × 2.5 × 10 = 300 J
Since mgh = Kinetic Energy at bottom.
Thus; kinetic energy of the ball once it reach the ground = 300 J
A volume of 25 milliliters is the same as a volume of ____________________ cubic centimeters.
Answers
Answer:
25 cm³
Explanation:
In the conversion of units, we know that are one cubic centimeters (cm³) in a milliliter (mL) .
1 milliliter = 1 cubic centimeter
25 milliliters = 25 cubic centimeters
Therefore, a volume of 25 milliliters is the same as a volume of 25 cubic centimeters.
This ultimately implies that, the volume of an object in milliliters is equivalent to its volume in cubic centimeters.

Describe how the motion of the particles within the popcorn changes as thermal energy is transferred. How do they start out? How does that change? What other transformations occur?
Answers
Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.
Explanation:
Answer:
Why do you think transferring energy into or out of a substance can change the molecules’ freedom of movement?
Explanation:
We know that transferring energy can cause a change in molecules' freedom of movement. Another way to say this is that transferring energy into or out of a substance can cause a phase change.

Which term, when divided by volume, equals density?
A) Distance
B) Power
C) Mass
D) Weight
Answers
Answer:
C) Mass
Explanation:
The mass of an object divided by its volume equals the density.
Hope this helps!
The term when divided by volume, equals density is known as Mass. Thus, the correct option for this question is C.
What is Density?Density may be defined as a type of physical property that significantly deals with the description of how much space an object or substance takes up with respect to the amount of matter in that object or substance.
In a more simple sense, it is characterized as the measurement of quantity or mass per unit of volume in a particular substance.
The formula for calculating the density is as follows:
Density = Mass/Volume.Therefore, the term when divided by volume equals density is known as Mass. Thus, the correct option for this question is C.

2.Real images are:
A.always inverted
B.magnified or diminished
C.can be obtained on screen
D.all the above
Answers
Answer:
see below
Explanation:
1) B, virtual because the when you stand in front of a mirror, the image formed is virtual and Image is laterally inverted
2) D because, when using converging lens , real image is formed, it is inverted and it can also be magnified or diminished when the object is placed at different focal length.
real image can be captured on the screen because light rays meet at the image position
when using converging lens, the image formed if it is virtual is upright.
