Answer:
Let M1 = 8 kg and M2 = 34 kg
F = M a = (M1 + M2) a
F = M2 g the net force accelerating the system
M2 g = (M1 + M2) a
a = M2 / (M1 + M2) g = 34 / (42) g = .81 g = 7.9 m/s^2

According to the visible spectrum, we can deduce the following:
- Objects that absorb shorter wavelengths of light are perceived as <u>red</u>.
- Objects that absorb longer wavelengths are perceived as <u>blue</u>.
- Objects that reflect all wavelengths are perceived as <u>white</u>.
- Objects that absorb all wavelengths are perceived as <u>black</u>.
<h3>What is light?</h3>
Light can be defined as a form of electromagnetic waves (radiation) that do not require any medium for its propagation. Thus, light is generally referred to as a visual signal because it can be seen with the eyes.
<h3>The wavelength of light.</h3>
Based on scientific records, the wavelengths of light that can be seen by humans with their eyes is between the range of 400 to 750 nanometers (nm).
According to the visible spectrum, we can deduce the following:
- Objects that absorb shorter wavelengths of light are perceived as <u>red</u>.
- Objects that absorb longer wavelengths are perceived as <u>blue</u>.
- Objects that reflect all wavelengths are perceived as <u>white</u>.
- Objects that absorb all wavelengths are perceived as <u>black</u>.

Answer:
m = 50 [kg]
Explanation:
The potential energy can be calculated by means of the following equation.

where:
Ep = potential energy = 735 [J]
m = mass [kg]
g = gravity acceleration = 9.81 [m/s²]
h = elevation = 1.5 [m]
Now replacing:
![735=m*9.81*1.5\\m = 50 [kg]](https://tex.z-dn.net/?f=735%3Dm%2A9.81%2A1.5%5C%5Cm%20%3D%2050%20%5Bkg%5D)
