Answer:

B) The unit of the variable on the y-axis is incorrect.

Explanation:

The question to this exercise is in the picture. It is '' What makes the above graph incorrect? ''

Let's analize each option :

A) The variables are plotted along incorrect axes. This is wrong because actually the graph is well-plotted. In a displacement versus time graph we put the time variable in the x-axis and the displacement variable in the y-axis.

B) The unit of the variable on the y-axis is incorrect. This is true. In the graph we can see that ''Displacement(\frac{m}{s})'' when the units of displacement are units of lengths such as meters or miles for example. Therefore, the B) is a correct option

C) The scale for each axis is not appropriate for the data. This is wrong. Because of the scale for each axis we are able to see the five  data points which are (1,2) ; (2,4) ; (3,6) ; (4,8) and (5,10)

D) The data points have not been plotted clearly. This is wrong. All data points are well-plotted signposted with a point at the intersection of the dashed coordinated lines. For example, the point (1,2) is at the intersection of two lines : one dashed line perpedicular to the x-axis at 1 and one dashed line perpendicular to the y-axis at 2

E) The data points have not been plotted accurately. This is wrong. The data points have been plotted accurately at the intersection of the coordinated dashed lines.

Finally, the only correct option is B)

What would happen if you tried to use a prism to disperse a beam that contained only green light?​
Margaret [11]

It is determined by the nature of the green light. Because lasers create light at almost a single frequency, green laser light would appear as a thin line of pure green. Other sources of "green" light emit light at a variety of frequencies, including yellow and blue, resulting in a strong green band in the center that fades into blue-green and yellow-green at the borders.

For example, here’s a graph of the spectrum of a green LED, showing the color range: Attachment #1

and here’s a graph of the transmission spectra of several standard photographic filters, including green: Attachment #2

The parking brake on a 1000 kg Cadillac has failed, and it is rolling slowly, at 1 mph , toward a group of small children. Seein
iogann1982 [59]

Answer:

0.5 mph in the opposite direction

Explanation:

m_1 = Mass of Cadillac = 1000 kg

v_1 = Velocity of Cadillac = 1 mph

m_2 = Mass of Volkswagen = 2000 kg

v_2 = Velocity of Volkswagen

In order to know the speed the system must have the momentum exchange

As the linear momentum of the system is conserved

m_1v_1+m_2v_2=0\\\Rightarrow v_2=-\dfrac{m_1v_1}{m_2}\\\Rightarrow v_2=\dfrac{1000\times 1}{2000}\\\Rightarrow v_2=-0.5\ mph

The speed of the impact is given by 0.5 mph in the opposite direction

A house is lifted from its foundations onto a truck for relocation. The house is pulled upward by a net force of 2850 N. This fo
Gwar [14]

Answer:

m = 95000 kg

Explanation:

Given that,

Net force acting on the house, F = 2850 N

Initial speed, u = 0

Final speed, v = 15 cm/s = 0.15 m/s

We need to find the mass of the house. Let the mass be m. We know that the net force is given by :

F = ma

Where

a is the acceleration of the house.

So,

F=m\dfrac{v-u}{t}\\\\m=\dfrac{Ft}{(v-u)}\\\\m=\dfrac{2850\times 5}{(0.15-0)}\\\\m=95000\ kg

So, the mass of the house is equal to 95000 kg.
