Difference between translatory and rectilinear motion.
Trava [24]
The difference is in way we observe some object that is moving. In translatory motion each point of the object has to go in straight line. A ball for example when kicked is rolling which means that not all of its oints are going in straight line. Some of points on ball are rotating. On the other hand in rectilinear motion it is only important that object is moving on straight line and it doesnt matter if it is rotating. So kicked ball that moves on ground is example of that.

Example of translatory motion can be our body in a bus that is going in straight line but not that wheels are rotating so they are moving rectilinear.

600 units of electricity and 100 units of gas were used for a total cost of $388. Next month, 400 units of electricity and 150 u
lana66690 [7]

Answer:

Cost per Electricity Unit= $0.61

Cost per Gas Unit= $0.22

Step-by-step explanation:

Suppose,

Cost per Electricity Unit: e

Cost per Gas Unit: g

for the first month condition, equation would be

600*e+100*g=388...........................................(i)

and for the next month condition, equation would be like

400*e+150*g=277...........................................(ii)

By solving both linear equations simultaneously, we get

e=0.61    and     g=0.22

5. A monument casts a 78 ft. shadow at the same time that a vertical yardstick casts a 4.5 ft. shadow. How high is the monument?
rodikova [14]

Hello,

Using Thalès 's theorem:

Let's h the height of the monument.

\dfrac{1}{h} =\dfrac{4.5}{78} \\\\h=\dfrac{78}{4.5} =\dfrac{156}{9} \approx{17.3\ (ft)}

If you don't know what is the Thalès's theorem,

imagine that the similar triangles.
