Answer:
A.) Maritime Tropical (mT)
Explanation:
Continental tropical is the air mass that forms over warm land.
Maritime Polar is the air mass that forms over cold water.
Continental polar is the air mass that forms over cold land.
So therefore A or Maritime Tropical is the correct answer
Wave A carries more energy than wave B. Wave B must have a smaller than wave A. A. frequency B. amplitude C. wavelength D. speed
Answer:
Amplitude
Explanation:
The amount of energy a wave carries is determined by the amplitude. The larger the amplitude, the more energy the wave has, and the smaller the amplitude, the less energy the wave has.
In this case, since wave A has more energy than wave B, wave B must have a smaller amplitude than wave A.

If a small planet were located 8.0 times as far from the sun as the Earth is, how many years would the planet take to orbit the sun?
Answer:
the time period is 22.63 years
Explanation:
The computation of the number of years taken is as follows:
According to the Keplers law
[tex]T^2 \propto R^3[/tex]
Here T denotes the time period
And, R denotes the average distance among the sun and planet
Now let us assume for earth
R_1 & T_1 be 1 year
So, for Planet
[tex]R_2 = 8R_1 , T_2 = ?[/tex]
Now applied Keplers law
[tex](\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674[/tex]
So, the time period is 22.63 years

Why do clouds and precipitation contain freshwater even though much of the water vapor comes from oceans and seas?
The atmosphere filters out the salt as precipitation is created
Most of the water doesn't come from the ocean, it comes from fresh water sources
Precipitation does contain 72% salt water
When water evaporates from the ocean, the salt is too dense to evaporate
Answer:
★ Most of the water doesn't come from the ocean, it comes from fresh water sources
Explanation:
Hope you have a great day :)
Most of the water doesn't come from the ocean, it comes from fresh water sources.
When water vapor in the sky condenses into droplets and hits the ground, rain is created. Although saltwater does turn into water vapor during the evaporation process, freshwater makes up the droplets that form in clouds. This is so that only the salt is left behind after the process of evaporation separates the freshwater from the saltwater.
The water vapor rises and cools, forming droplets that are virtually totally composed of freshwater when they condense.
The droplets that are heavy enough to defeat evaporation and fall as rain are the ones that make it to the earth.
Precipitation is the natural method of removing salt from water and creating fresh water.

A crane lifts a 3,000 kg beam of concrete from the ground to a height of 50m. What work is being done on the concrete?
Answer:
The work done on the concrete is 1,470,000 J
Explanation:
Given;
mass lifted by the crane, m = 3,000 kg
height through which the mass was lifted, h = 50 m
The work done on the concrete is equal to the gravitational potential energy of the concrete due to the height it was raised.
E = W = mgh
W = mgh
W = 3000 x 9.8 x 50
W = 1,470,000 J
Therefore, the work done on the concrete is 1,470,000 J
PLS HELP! A boy drops a ball from an observation tower. The ball hits the ground in 3.0 s. What is the ball's velocity at the time of impact?
Answer:
v = u + at
v = 0 + 9.8 × 3
v = 29.4 m/sec
Answer: 29.4 m/s
Explanation:
We find the answer by using this equation:
v2 = v1 + a * t
Let's figure out what our variables are.
v2 = ?
We don't know the final velocity, so this variable is blank
v1 = 0
In a free fall, the velocity is 0
a = 9.8 m/s
Acceleration in a free-fall is 9.8 m/s
t = 3
It took 3 seconds for the ball to hit the ground
Now we plug our values.
v2 = v1 + a * t
v2 = 0 + 9.8 * 3
v2 = 0 + 29.4
v2 = 29.4

rest and motion are relative terms why?
Answer:
Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.

A projectile is launched with an initial velocity 60m/s at an angle 60° to the vertical. What the magnitude of it's displacement after 5s.
Answer:
the magnitude of the displacement after 5s is 137.31 m.
Explanation:
Given;
initial velocity of the projectile, u = 60 m/s
angle of projection, θ = 60°
time of motion, t = 5s
the vertical component of the velocity, [tex]u_y= u\ sin \theta = 60sin(60^0)[/tex]
The magnitude of the displacement after 5s is calculated as;
[tex]h = u_yt -\frac{1}{2} gt^2\\\\h = 60sin (60^0)\times 5 - \frac{1}{2} (9.8)(5)^2\\\\h = 259.81-122.5\\\\h = 137.31 \ m[/tex]
Therefore, the magnitude of the displacement after 5s is 137.31 m.

Calculate the potential energy of a roller coaster when mass is 53 kg and
height is 818 m.
10 points !
Answer:
P.E = 424869.2 Joules
Explanation:
Given the following data;
Mass, m = 53kg
Height, h = 818m
We know that acceleration due to gravity, g is equal to 9.8m/s²
To find the potential energy
P.E = mgh
Substituting into the equation, we have
P.E = 53*818*9.8
P.E = 424869.2 Joules
Therefore, the potential energy of the roller coaster is 424869.2 Joules.

A spring with a spring constant of 400 n / M has a mass hung on it so it stretches 8 cm. calculate how much mass the spring is supporting.
Answer:
3.3kg
Explanation:
Given parameters:
Spring constant = 400N/m
Extension = 8cm = 0.08m
Unknown:
Amount of mass the spring is supporting = ?
Solution:
To solve this problem:
F = kE
F is the force
k is the spring constant
E is the extension
So;
F = 400 x 0.08 = 32N
Mass;
Force = mass x acceleration due to gravity
32 = mass x 9.8
Mass = 3.3kg
The mass the spring is supporting is 3.27 Kg.
We'll begin by calculating the force acting on the spring.
Spring constant (K) = 400 N/mExtension (e) = 8cm = 8 / 100 = 0.08 mForce (F) =?F = Ke
F = 400 × 0.08
F = 32 N
Finally, we shall determine the mass. This can be obtained as follow:
Force (F) = 32 NAcceleration due to gravity (g) = 9.8 m/s²Mass (m) =?m = F / g
m = 32 / 9.8
m = 3.27 Kg
Therefore, the mass the spring is supporting is 3.27 Kg

Question 5 options:

1.
When a cold air mass and a warm air mass meet but are at a standstill, the boundary is called
2.
If warm or more humid air presses forward and colder or drier air draws back, the boundary is called
3.
If colder or drier air presses forward and warmer or more humid air draws back, the boundary is called
4.
Sometimes a warm air mass can get caught between two cold fronts, which can force the warm air up into a wedge shape.
Answer:
Cold Front 3 // Stationary Front 1 // Warm Front 2 // Occluded Front 4
Explanation:
It's simple. Warm front means the warm air is pressing forward, which is why it's a warm front. Stationary Front, meaning they're at a standstill, also makes sense because stationary means not moving. Then since your last option is Occluded Front, since the others already have an answer, you have no choice but to match 4 with it. I took the quiz and got the answer right. :D

a light wave travels from air into a medium of refractive index 1.54. If the wavelength of the light in air is 5.4 * 10^-7. calculate its wavelength in the medium
3.51 × 10^-7m
Explanation:
Refractive index = wavelength of the light in air ÷ wavelength in the medium
wavelength in the medium = wavelength of the light in air ÷ refractive index
= 5.4 * 10^-7 ÷ 1.54
= 3.51 × 10^-7m

B. An asteroid moves through space at constant velocity.
C. A baseball bat strikes a baseball.
D. A woman is sitting on a chair.
Answer:
C. A baseball bat strikes a baseball.
Explanation:
Newton's second law of motion states that acceleration happens when force is applied on the mass.
A baseball bat strikes a baseball is the best example of Newton's second law of motion because acceleration of the baseball is directly proportional to the force by which baseball bat hit it.
Hence, the correct option is 'C. A baseball bat strikes a baseball.'
