A gas has an initial volume of 168 cm3 at a temperature of 255 K and a pressure of 1.6 atm. The pressure of the gas decreases to

1.3 atm, and the temperature of the gas increases to 285 K.
What is the final volume of the gas?

P1V1/T1 = P2V2/T2

(1.6atm)(168cm^3)/(255K) = (1.3atm)V2/(285K)

Final volume = 231cm^3

A ball is whirled on the end of a string in a horizontal circle of radius R at constant speed v. Which way(s) can increase the c
Sav [38]

Answer:

A, B and F are the right answers

Explanation:

The formula is a_{c} = v^{2} / r

A) Increasing both the radius and the speed by a factor of 9

a_{c} = (9v)^{2} / (9r) = 9v^{2} / r

<u><em>which means the acceleration will increase by a factor of 9</em></u>

B) Keeping the speed fixed and decreasing the radius by a factor of 9

a_{c} = (v)^{2} / (r/9) = 9v^{2} / r

<u><em>which means the acceleration will increase by a factor of 9</em></u>

C) Keeping the radius fixed and increasing the speed by a factor of 9

a_{c} = (9v)^{2} / (r) = 81v^{2} / r

It will increase the acceleration 81 times

D) Keeping the speed fixed and increasing the radius by a factor of 9

a_{c} = (v)^{2} / (9r) = v^{2} / 9r

It will decrease the acceleration by 9 times

E) decreasing both the radius and the speed by a factor of 9

a_{c} = (v/9)^{2} / (r/9) = v^{2} / 9r

It will decrease the acceleration by 9 times

F) Keeping the radius fixed and increasing the speed by a factor of 3

a_{c} = (3v)^{2} / (r) = 9v^{2} / r

<u><em>It will increase the acceleration by 9 times </em></u>

Find the resultant force of the following forces :
bezimeni [28]

The resultant of the given forces is; 6√2 N

<h3>How to find the resultant of forces</h3>

We are given the forces as;

10 N along the x-axis which is +10 N in the x-direction

6 N along the y-axis which is +6N in the y-direction

4 N along the negative x-axis which is -4N

Thus;

Resultant force in the x-direction is; 10 - 4 = 6N

Resultant force in the y-direction is; 6N

Thus;

Total resultant force = √(6² + 6²)

Total resultant force = 6√2 N

Cathy, a 460-N actress playing Peter Pan, is hoisted above the stage in order to "fly" by a stagehand pulling with a force of 60
SCORPION-xisa [38]

Answer:7.67

Explanation:

Given

Weight of Cathy W_1=460\ N

Force exerted by rope F=60\ N

Mechanical advantage is the ratio of load by Pulling effort      

M.A.=\frac{Load}{Pulling\ effort}

M.A.=\frac{460}{60}

M.A.=7.67\ N

How much electrical potential energy is stored in a capacitor that has 8.0 × 10-10 C of charge on each plate and a potential dif
arsen [322]
THere is a standard relationship that gives this result where the capacity of the capacitor is used:
E=1/2* \frac{Q^2}{C}.
We know though that Q/c=V and thus we can use the relationship:
E=Q*V/2 where we have just substituted in. If we also take into account that Q=VC, we can also get that E=V^2*C/2.
We are given the charge and the potential, so the best expression to use is the middle one.
Substituting, we get that E=1/2*8*10^(-10)*20=8*10^(-9).

The answer is B
