A 174 pound Jimmy Cheek is riding on a 54 ft diameter Ferris Wheel. The normal force on Jimmy Cheek is 146 pounds when Jimmy is

Veronika [31]

To solve this problem we will apply the concepts related to the balance of Forces, the centripetal Force and Newton's second law.

I will also attach a free body diagram that allows a better understanding of the problem.

For there to be a balance between weight and normal strength, these two must be equivalent to the centripetal Force, therefore

$F_c = W-N$

$m\omega^2r = W-N$

Here,

m = Net mass

$\omega$ = Angular velocity

r = Radius

W = Weight

N = Normal Force

$m\omega^2r = 174-146$

The net mass is equivalent to

$F = mg \rightarrow m = \frac{F}{g}$

Then,

$m = \frac{174lb}{32.17ft/s^2}$

Replacing we have then,

$(\frac{174lb}{32.17ft/s^2})\omega^2 (54ft) =174lb-146lb$

Solving to find the angular velocity we have,

$\omega = 0.309rad/s$

Therefore the angular velocity is 0.309rad/s

Convert 6.6 meters to centimeters

Lina20 [59]

Answer:

660 centimeters

Explanation:

There are 100 cm in 1 m. To convert from m to cm, multiply by 100.

$6.6 \times 100 = 660$

There are 660 cm in 1 m.

In-s [12.5K]

As the distance between the two slits is decreased, the distance between light bands in the pattern on the screen will increase. The correct option among all the options that are given in the question is the second option or the penultimate option. I hope that this is the answer that has actually helped you.

A cook puts 1.90 g of water in a 2.00 L pressure cooker that is then warmed from the kitchen temperature of 20°C to 111°C. What

sergey [27]

Answer:

P= 168258.30696 Pa

Explanation:

Given that

Mass of water vapor m = 19.00 g

Volume of water vapor V = 2.00 L

$=2.00\times10^{-3}m^3$

Temperature of water vapor is T = 111°C

= 384K

Molar mass of water is M = 18.0148 g/mol

Number of moles are

n = m/M

= (1.90 g)/(18.0148 g/mol)

= 0.1054 mol

Pressure inside the container is

P= nRT/V

$P=\frac{(0.1054)(8.314472)(384)}{(2.00\times10^{-3})}$

P= 168258.30696 Pa

Since the discrete Fourier series, the Sampling rate, would be the equivalent of the inverse of the passage of time, that is, to the frequency, mathematically this can be written as,
