AURORKA [14]3 years ago
4 0

Answer:g=a=10m/s^2,

M=40kg,

S=150mm/1000=0.15m*30steps each=4.5m,

F=ma=40*10=400N

Power=W/t=F*s/t=F*V=1800/6 = 300W or 0.3kW

The elements fluorine and chlorine can form minerals in the _____ group
navik [9.2K]

The elements fluorine and chlorine can form minerals in the "halide"group .


Halide refers to the group containing halogens. The halogens turn out to be less responsive as you go down the group. Fluorine, at the highest point of the group, is the most responsive or reactive halogen. It is to a great degree risky, causing serious synthetic consumes on contact with skin.

Halogens also act as bleaching agents.They will evacuate the shade of colors. Chlorine is utilized to bleach wood mash to influence white paper.

Write the physics equation for this graph in slope-intercept form (y=mx+b), expressed in terms of the appropriate variables.
alexgriva [62]

The equation that describes the graph is y = 16.7x + 150.

<h3>What is the equation?</h3>

We have been given the graph of a certain function data set in physics. We know that the graph is the representation of data on cartesian coordinates. In this case, we are asked to find the equation of the graph in the form; y=mx+b

m = slope of the graph

b = intercept of the graph.

To obtain the slope;

m = y2 - y1/ x2 - x1

m = 400 - 200/ 16 - 4

m = 200/ 12

m = 16.7

Then we can see from the graph that the y - intercept is 150. Having these data, the equation that could describe the graph is now;

y = 16.7x + 150

How does the wavelength of maximum absorbance relate to color?
eimsori [14]

Answer:when a white light falls on an object, the wavelength of maximum absorbance is removed by absorption and the remaining wavelength are reflected to the eye.

Explanation:Furthermore,this relationship entails that the color not absorbed is the color of the object,for example plants are green because they reflect green light and absorb red and blue light.
