How much heat is lost through a 3’× 5' single-pane window with a storm that is exposed to a 60°F temperature differential?A. 450 Btu/hB. 900 Btu/hC. 1350 Btu/hD. 1800 Btu/h

Answers

Answer:

A. 450 btu/h

Explanation:

We solve this problem by using this formula:

Q = U x TD x area

U = U value of used material

TD = Temperature difference = 60°

Q = heat loss

Area = 3x5 = 15

We first find U

R = 1/u

2 = 1/U

U = 1/2 = 0.5

Then when we put these values into the formula above, we would have:

Q = 0.5 x 15 x 60

Q = 450Btu/h

Therefore 450btu/h is the answer

A 60-Hz 3-phase induction motor is required to drive a load at approximately 850 rpm. How many poles should the motor have

Answers

Answer:

8 poles

Explanation:

Given

[tex]Frequency, f = 60Hz[/tex]

[tex]Speed, n_s = 850rpm[/tex]

Required

Calculate the number of poles the motor should have?

To solve this question, we make use of synchronous angular velocity  formula

[tex]n_s = \frac{120f}{P}[/tex]

Where

[tex]P = Number\ of\ Poles[/tex]

Substitute values for [tex]n_s[/tex] and f in [tex]n_s = \frac{120f}{P}[/tex]

[tex]850 = \frac{120 * 60}{P}[/tex]

[tex]850 = \frac{7200}{P}[/tex]

Multiply both sides by P

[tex]P * 850 = \frac{7200}{P} * P[/tex]

[tex]P * 850 = 7200[/tex]

Divide both sides by 850

[tex]\frac{P * 850}{850} = \frac{7200}{850}[/tex]

[tex]P = \frac{7200}{850}[/tex]

[tex]P = 8.47058823529[/tex]

However, the number of poles must be an integer.

So:

[tex]P = 8[/tex]

How large a force is required to accelerate a 1300 kg car from rest to a speed of 20 m/s in a distance of 80 m?

Answers

F=m*a

F=80*20

F =1600 ans"

Answer: basically we are asked to find it's force and the formula that helps us to find force is Force= Mass× Acceleration

so let's put out the given and what we need to find

GIVEN. Solution

F=m.a

Mass= 1300. F=1300kg×20m/s

speed (Acceleration)=20m/2. F=26000Kg.m/s

Force=? F=26000N

N stands for Newton and the reason that it comes Newton is because it is the SI-unit of Force and the result of kg×m/s.

Hannah wrote the paragraph below about human errors that were made during the Chicago fire of 1871.Several key human errors contributed to the spread of the Chicago fire of 1871. When the blaze first began, Bruno Goll refused to sound the first alarm, which was housed in his drugstore. Later, at the courthouse, Mathias Schaffer instructed his assistant, William J. Brown, to sound Box 342 instead of Box 319, sending firefighters toward the wrong location. When Schaffer realized his mistake, Brown flat-out refused to strike the correct box. Even after the fire, Brown was confident in his decision not to correct the mistake.
