Well, you didn't ask a question, and 4 m/s is not an angular speed.
So all I can offer is a couple of observations:
1). The tension in the rope is
M V² / R = (1.5 kg) x (4 m/s)² / R
= (24 kg-m²/s²) / (distance of the ball from the pole).
2). Tetherball was the only thing I played at camp,
more than 60 years ago, and I loved it !
It was a tough game, because we had to skin
our own T.Rex and use his hide to make the ball
and his guts for the rope.
Answer:
n=0.03928 moles
Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles
Explanation:
The amount of oxygen which lung can have is 20% of 5 L which is the capacity of lungs
Volume of oxygen in lungs =V=5*20%= 1 L=
Temperature=T=
Pressure at sea level = P= 1 atm=
R is universal Gas Constant =8.314 J/mol.K
Formula:
Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles
Answer:
8962.5 N
Explanation:
From fundamental kinematics equations, acceleration, a is given by 
where v is final velocity, u is initial velocity and t is time
We also know that force is a product of mass and acceleration of an object and substituting in the formula F=ma we obtain
where m is the mass of the body
Therefore, the force is 8962.5 N
Before answering this question it is necessary to know the conversion factors for temperatures.
<em>273 k = 0 ° C
</em>
To transform a temperature from Kelvin to ° C we use the following Formula
T ° C = T Kelvin - 273
<u>For 373 K</u>
373K -273 = 100 ° C
<em>373 Kelvin equals 100° C.
</em>
To transform a temperature from ° C to ° F we use the following formula:
(T° C x 9/5) + 32 = T ° F
Then:
<u>For 0 ° C
</u>
(0° C x 9/5) +32 = 32 ° F
<em>0° C equals 32 ° F.
</em>
<u>For 100° C
</u>
(100 ° C x 9/5) +32 = 212 F
<em>100 ° C equals 212 ° F.
</em>
Therefore, the correct option is the first:
373 Kelvin = 100 ° C = 212 ° F
