The graph shows the amplitude of a passing wave over time in seconds (s) What is the approximate frequency of the wave shown? A. 6 Hz B. 0.2 0.4 Hz
Answer:
0.2 I took the test
Explanation:
I took the test
The time period of the whole wave cycle is 6 seconds but the time period of one complete wave is about 4 seconds here. The inverse of this time period is the frequency, that is 0.2 Hz.
What is frequency ?Frequency by definition is the number of events per unit time. Frequency of a wave is the number of wave cycles in one second. It is the inverse of the time period.
Frequency is directly related to the energy of the wave. As the frequency increases, energy of the wave also increases. In the given graph the wave cycle is given for a time of 6 seconds.
The time period for one complete wave is 4 second from the graph.
thus, T = 4 s
v = 1/T
= 1/4 = 0.2 s⁻¹ or 0.2 Hz
Therefore, the frequency of the wave shown, is 0.2 Hz.

Does the earth have mass
Answer:
yes it does
Explanation:
it's not like Balloon it is a solid so it the earth does have a mass
A mass sitting on a horizontal, frictional surface is attached to one end of a spring; the other end is fixed to a wall. 3.0 J of
work is required to compress the spring by 0.20 m. If the mass is released from rest with the spring compressed, it
compresses a maximum acceleration of 15 m/s?.
a) Determine the spring constant.
b) Determine the mass.
d) What is the velocity when the mass reaches maximum acceleration?
c) Deterinine the net force when the mass passes 0.10m compression
d) Determine the acceleration when the mass passes 0.10m compression.
e) Determine the velocity when the mass passes 0.10m compression
Answer:
I started answering this before everything was erases, but briefly
W = 1/2 K x^2 so K = 2 W / x^2 = 6 * 25 = 150
Also F = - K X = 150 * 1/5 = 30 N at max extension
m = F / a = 30 /15 = 2 kg
Since max extension occurs at t = 0 you can write
x = A sin ω t
v = ω A cos ω t
a = -ω^2 A sin ω t note that there is no phase angle here
Also at .1 compression
.1 = .2 sin ω t and sin ω t = 1/2 and ω t = 30 deg = pi / 6
Substiture these values above to get velocity and acceleration when
ω t = 30 deg

A 780 kg vehicle accelerates at 4 m/s2. How much force is the car generating?
Explanation:
Given
mass (m) = 780 kg
acceleration (a) = 4 m/s²
Force (F) = ?
We know
F = m * a
= 780 * 4
= 3120 Newton
The car is generating 3120 Newton force.

what determines the color of light?
1. brightness
2. wavelength
3. amplitude
4. reflection rate
Answer:
2. wavelength
Explanation:
Light moves in waves. Light waves are different from sound waves in that light travels in transverse waves (as opposed to longitudinal, which is how sound waves travel). A light wave that travels in a direction is called a light ray.
Just like other waves, light waves have a wavelength and amplitude. The wavelength determines the color; we will learn more about this in the lesson on color. The amplitude of a light wave determines the brightness. Just as large amplitudes in sound waves result in sounds with greater intensities (louder sounds), large amplitudes in light waves result in light with greater intensity (brighter light).

Maisey is running 12mph and comes to an abrupt stop in 3 seconds when she hears her name called. What is her acceleration?
Answer:
~ 0.001 m/s^2
Explanation:
If you convert 12 miles per hour to, miles per second, it makes this easier to calculate, so do that first
12m/ 1 hour * 1 hour/ 60 mins * 1 min/ 60 sec = ~0.003333 miles per second.
Next remember that acceleration = velocity/time
So our new velocity: 0.003333 over time: 3 seconds = the acceleration.
0.003333/3 = 0.001 m/s^2

Denver, Colorado is located near the rocky mountains. Which list of controls below would have the strongest influence on the weather in Denver.
A ) Ocean currents, distance from large bodies of water, and altitudes
B ) Altitude, topography, and ocean currents.
C ) Latitude, altitude, and topography
D ) Topography, ocean currents, and latitude.
Answer:To understand the regional and local climates of Colorado, you must begin with a basic knowledge of Colorado's topography. Colorado lies astride the highest mountains of the Continental Divide. Nearly rectangular, its north and south boundaries are the 41° and 37° N. parallels, and the east and went boundaries are the 102° and 109° W. meridians. It is eighth in size among the 50 states, with an area of over 104,000 square miles. Although known for its mountains, nearly 40 percent of its area is taken up by the eastern high plains.
Of particular importance to the climate are Colorado's interior continental location in the middle latitudes, the high elevation of the entire region, and the mountains and ranges extending north and south approximately through the middle of the State. With an average altitude of about 6,800 feet above sea level, Colorado is the highest contiguous State in the Union. Roughly three-quarters of the Nation's land above 10,000 feet altitude lies within its borders. The State has 59 mountains 14,000 feet or higher, and about 830 mountains between 11,000 and 14,000 feet in elevation.

the relationship between force and acceleration verification of Newton second law of motion
Answer:
below
Explanation:
According to Newtons Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
