Answer:

R1=3.333 Ohms

R2=10 Ohms

R3=16.666 Ohms

Explanation:

30 total

30=R1+R2R3

30=1(x):3(x):5(x)

x=3.3333

R1=3.333 Ohms

R2=10 Ohms

Acceleration involves a change in __________.
uysha [10]

"Acceleration" is any change in speed or direction of motion ...
slowing down, speeding up, or curving away from a straight line.

You and I, and all other students of Physics, must re-educate
people.  We have to tell everyone that 'acceleration' does NOT
mean 'speeding up'.  AND, it doesn't even necessarily mean
any change in speed.

The advantage of using a chain over a belt drive
vitfil [10]
<span>A belt drive requires less maintenance, lasts longer and is cleaner. It also delivers a smoother ride, which is why this type of drive system is most commonly used on cruiser motorcycles.A chain drive, on the other hand, delivers power more economically than a belt drive, and it sends more of the power that the engine produces to the wheel. While they require more maintenance, the improved performance means they are the more common type of drive method.</span>

Find the circumference of a circle whose area is 452.16 square meters. (Use 3.1416 as the value of .)
kakasveta [241]

1) The area of a circle is given by

A=\pi r^2

where r is the radius of the circle. In this problem, we are told that the area is

A=452.16 m^2

so we can rearrange the previous equation to calculate the radius:

r=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{452.16 m^2}{3.1416}}=12.0 m


And now we can find the circumference, by using the formula:

c=2 \pi r=2 \pi (12.0 m)=75.3984 m

Therefore, the correct answer is D. 75.3984 meters.



2) The volume of a cube is given by:

V=L^3

where L is the length of the edge. In this problem, L=6 cm, therefore the volume of the cube is

V=L^3=(6 cm)^3=216 cm^3


and so, the correct answer is A. 216 cu. cm.
