D. Gravity anomalies.
Out of all choices, Gravity anomalies provide evidence that crust is thin under the mid ocean ridge.
Answer: Option D
Explanation:
Gravity promotes subduction zones. We can perform geological processes with the help of geological processes, because the process in which the oceanic crust moves to the mantle as soon as it collides with the continental crust.
Subduction destroys the ocean's crust, pushing it into the mantle in which it melts. It is said that the ocean's crust is weak because it contains more mafic minerals and is approaching its borders again. If there is a difference between the continental crust, the oceanic crust sank into the mantle.
A stone falling from a cliff increases speed until it reaches constant velocity, or terminal velocity. What does the stone’s motion tell you about the forces acting on the stone?
Since the stone is moving faster it is pushing through the air faster, which means it is going down faster.
* CRIMINOLOGY*
A mandatory minimum is _____.
A.the mandatory minimum number of jurors that serve on a federal jury
B.a minimum sentence that must be imposed by a judge if an individual is found guilty of the crime
C.the minimum number of individuals in a prison cell block
D.the number of guards required per 10 inmates
I think the answer is B.
Hope this helps.
A mandatory minimum is "a minimum sentence that must be imposed by a judge if an individual is found guilty of the crime".
Answer: Option B
Explanation:
Necessary minimum penalties are criminal sentences that involve minimum punishments determined by law. they'll apply to specific offences, specific offenders, or to explicit mixtures of offence and bad person characteristics.
The goal of those laws after they were developed was to push uniformity; it does not matter however strict or lenient your decide is, because the law and therefore the law alone determines the sentence you receive.

If the index of refraction of a medium is 1.4, determine the speed of light in that medium.
4.2 x 108m/s
2.1 x 108m/s
4.7 x 10-9m/s
4.7 x 108m/s
The refractive index of a medium can be calculated by the use of the angle of incidence and angle of refraction, or the speed of light in air and the speed of light in the medium
The speed of light in air is 3×10⁸m/s.
then n= (speed of light in a air)/(speed of light in the medium.)
1.4=(3ₓ10⁸)/(speed of light in the medium)
speed of light in the medium=3ₓ10⁸m/s÷1.4= 2.1×10⁸m/s
=2.1×10⁸m/s
A boy on a bicycle rides at 21.1m/s distance of 87.9m how long does it take
Answer is t=4,2 seconds
Due to

sorry if im wrong but
D. A satellite orbiting the Earth.
I would have to say D. Kinetic energy is an energy that is associated with motion and in this case the only options that posses an energy in motion is D.
What is the IMA of the following pulley system? 1 2 3 4
The answer is 2
I did this question today on my Odyssey ware, and I believe the explanation is that each supporting rope increases the IMA by 1
Answer:
IMA of pulley system is 3
Explanation:
The full form of IMA is ideal mechanical advantage. It is also defined as the ratio of output force to the input force. The mathematical expression is given by :
[tex]IMA=\dfrac{F_r}{F_e}[/tex]
For the pulley system, the IMA is equal to the number of ropes present in the pulley - mass system. So, it is quite easy to find IMA of the pulley i.e. just counting the number of ropes present in the system.
In the given figure, there are three ropes in the system. Hence, its IMA is 3.

A sound wave has a speed of 343 m/s in air. What is the wavelength of a sound wave with a frequency of 686 Hz
Wavelength is the distance between 2 adjacent points in a wave
we can use the following equation to find the wavelength of a sound wave
wavelength = speed / frequency
frequency is the number of waves passing a point in 1 second
substituting the values in the equation
wavelength = 343 m/s / 686 Hz
wavelength = 0.5 m
wavelength of the wave is 0.5 m
The wavelength of a sound wave with a frequency of 686 Hz traveling through air with a speed of 343 m/s is calculated using the formula extlambda = v / f, which gives a wavelength of 0.5 meters.
To find the wavelength of a sound wave with a given frequency, you can use the formula:
v = f imes ext{ extlambda}
Where v is the speed of sound in the medium, f is the frequency, and ext{ extlambda} (lambda) is the wavelength. Given that the speed of sound (v) in air is 343 m/s and the frequency (f) of the wave is 686 Hz, we can rearrange the equation to solve for the wavelength ( ext{ extlambda}):
ext{extlambda} = v / f
Plugging in the values:
ext{extlambda} = 343 m/s / 686 Hz
ext{extlambda} = 0.5 m
So, the wavelength of a sound wave with a frequency of 686 Hz traveling through air at a speed of 343 m/s is 0.5 meters.
An atom gains an additional electron. What is the overall charge of the ion that is formed?
An is formed when an atom loses or gains one or more electrons. Because the number of electrons in an ion is different from the number of protons, an ion does have an overall electric charge. Consider how a positive ion can form from an atom. The left side of the illustration below represents a sodium (Na) atom
It is a negative ion
What is cosmic ray spallation
Cosmic ray spallation is a form of naturally occurring nuclear fission and nucleosynthesis
How does a low pressure system determine the weather in an area?
Knowing areas of high and low air pressure is important to predicting the weather because differences in air pressure causes wind to form. ... This is because low pressure systems generally attract warm and moist air. On a weather map a low pressure system is shown by a red L.
How was the teapot dome scandal discovered and resolved?
The Teapot Dome Scandal of the 1920s shocked Americans by revealing an unprecedented level of greed and corruption within the federal government. Albert Fall, a former Secretary of the Interior, was charged with accepting bribes from oil companies in exchange for exclusive rights to drill for oil on federal land.
HOPE THIS HELPED!!! XD
Answer:
The Teapot Dome scandal was a corruption scandal discovered in 1922 during Harding administration. The scandal originated from the sale of land owned by the United States Navy in Wyoming and California by Interior Minister Albert Bacon Fall at a substandard price and direct appointment to a private oil company. Secretly, Fall sold the land in Wyoming to oil entrepreneurs from Mammoth Oil Company and then two fields in California to Pan-American Petroleum Company. This scandal was revealed in the public after the senate held a deep and further investigation.
Domestic Minister Albert B. Fall requested resignation in March 1923, and served a year in prison for corruption.
The scandal also weakened the general picture of the Harding administration, which has already begun to decline in popularity due to the action of the Great Railroad Strike in 1922 and the President's veto on the issue of Bonus Act of 1922.
In order to move a bag of dog food across a 10 meter room, you apply 20 newtons of force. How much work was done? (2 points)
Work in physics is defined as force times distance (there is also an angle but that doesn’t seem applicable here). In this case:
W = F•d
W = (20 N)(10 m)
W = 200 Nm or 200 joules
200 joules of work was done on the bag of dog food.
Hope this helps!
Answer:
i have seen people put its 2joules, well it not 2, its 200joules bc their asking how much work was done so u need to multiply not dived

Explanation:
Locomotion is associated with movement.
The word is derieved from two Latin words,
Loco----place
Motio----to move.
a dock worker pushes a 150.0 kg crate up a ramp that is 3.00 m high and 10.00 m long into the cargo bay of a ship. He exerts a 800.0 N force parallel to the ramp. find both the mechanical advantage and ideal mechanical advantage of the ramp. what is the efficiency of the ramp?
Efficiency: (2940 J / 3250 J) x 100% = 90.46%
The mechanical advantage of the ramp is 1.8375, the ideal mechanical advantage is 3.3333, and the efficiency of the ramp is 55.11%.
The mechanical advantage (MA) of a ramp is the ratio of the weight of the object being moved to the force required to move it up the ramp. The ideal mechanical advantage (IMA) is the ratio of the ramp's length to its height, assuming no friction. The efficiency of the ramp is the ratio of MA to IMA, expressed as a percentage.
To calculate MA:
First, find the weight of the crate, which is equal to mass times gravity (150.0 kg * 9.8 m/s2 = 1470 N).
Then, divide the weight by the applied force (1470 N / 800.0 N = 1.8375).
Therefore, MA=1.8375.
To calculate IMA:
Divide the length of the ramp by its height (10.00 m / 3.00 m = 3.3333).
Hence, IMA=3.3333.
To find the efficiency:
Divide MA by IMA (1.8375 / 3.3333 = 0.5511).
Multiply by 100 to get the percentage (0.5511 * 100 = 55.11%).
The efficiency of the ramp is therefore 55.11%.
