Answer:
0.4167 ft/s
Explanation:
The law of conservation is applied to point A and B.
This gives:
![T_{A} + V_{A} = T_{B} + V_{B}](https://tex.z-dn.net/?f=T_%7BA%7D%20%20%2B%20V_%7BA%7D%20%3D%20T_%7BB%7D%20%2B%20V_%7BB%7D)
Hence,
is the kinetic energy at the position A
is the velocity at point A
Considering point A, the kinetic energy at the point will be:
![T_{A} = 0](https://tex.z-dn.net/?f=T_%7BA%7D%20%3D%200)
The potential energy will be:
![V_{A} = (V_{A})_{g} + (V_{A})_{c}](https://tex.z-dn.net/?f=V_%7BA%7D%20%3D%20%28V_%7BA%7D%29_%7Bg%7D%20%2B%20%28V_%7BA%7D%29_%7Bc%7D)
Hence,
is the potential energy and
is the kinetic energy
The potential energy is given by the following:
![V_{Ag} = mgr](https://tex.z-dn.net/?f=V_%7BAg%7D%20%20%3D%20mgr)
substituting 1 lb for mg gives 0.4167 ft for r
Then the velocity, ![V_{Ag} = 1lb * 0.4167ft\\ = 0.4167 ft](https://tex.z-dn.net/?f=V_%7BAg%7D%20%20%3D%201lb%20%2A%200.4167ft%5C%5C%20%20%20%20%20%20%20%20%20%20%20%20%20%3D%200.4167%20ft)
Answer:
The Border Patrol of the United States analyzes the purchase of a new helicopter for the aerial surveillance of the border of New Mexico and Texas with the Mexican Republic. 4 years ago a similar helicopter was purchased at a cost of $ 140,000.00. with an interest rate of 7% per year. Calculate the single payment factor and the present value factor with the above data with the table and formula. Draw the flow chart.

Explanation:
Cylindrical steel rod : diameter ( D ) , length L, uniform temperature T
Initial temp of water : To, heat transfer coefficient between steel rod surface and water : h1
<u>The energy balance equation can be written as :</u>
Rate of convectional heat loss = Rate of decrease in internal energy with respect to time
cp = heat capacity of body, v = volume , р = density of body
attached below is the heat transfer differential equation and boundary and initial conditions
Answer:True
Explanation:Rotor matching is a term used to describe the process through a brake rotor is aligned to the hub and bearing assembly to produce a smooth, flat, and straight friction surface.
Rotor matching is an essential process which is required to prevent swirling of a break when a vehicle is stopping, rotor matching is needed for efficient and effective break system performance as it is one of the main determinant factors for accidents arising from break failures.
