Answer:

Explanation:Naturally occurring radioactive materials are present in its crust, the floors and walls of our homes, schools, or offices and in the food we eat and drink. There are radioactive gases in the air we breathe. Our own bodies - muscles, bones, and tissue - contain naturally occurring radioactive elements.

The gas tank of a certain luxury automobile holds 22.3 gallons according to the owner’s manual. if the density of gasoline is 0.

erik [133]

The mass of the fuel in the tank can be calculated by multiplying the volume in full tank to the density of the gasoline. First convert 22.3 gallons to ml by multiplying it with 3785.412 since the conversion factor is 1 gallon= 3785.412 ml. Then multiply the volume with the density. Since the density is in g/ml, you would get a value in grams so convert it to kg by dividing it with 1000. The convert the value in kg to lb multiply the value by 2.2. The values are 69.27 kg and 152.72 lb.

A potter's wheel rotating at 355 rev/min is switched off and rotates through 76.0 revolutions prior to coming to rest. What is t

Aliun [14]

Answer:

-1.44707 rad/s²

Explanation:

$\omega_f$ = Final angular velocity

$\omega_i$ = Initial angular velocity = 355 rpm

$\alpha$ = Angular acceleration

$\theta$ = Angle of rotation = 76 rps

Converting rpm to rad/s

$1\ rpm=\frac{2\pi}{60}\ rad/s$

Converting rps to rad/s

$1\ rps=2\pi \ rad/s$

Equation of rotational motion

$\omega_f^2-\omega_i^2=2\alpha \theta\\\Rightarrow \alpha=\frac{\omega_f^2-\omega_i^2}{2\theta}\\\Rightarrow \alpha=\frac{0^2-355\times \frac{2\pi}{60}^2}{2\times 2\pi \times 76}\\\Rightarrow \alpha=-1.44707\ rad/s^2$

The constant angular acceleration of the potter's wheel during this interval is -1.44707 rad/s²
