amm1812

Answer:

The types of solenoids are: AC Laminated Solenoid , DC Solenoid , Linear Solenoid ,and Rotary Solenoid.

Explanation:

  • The main purpose of solenoid is to generate the controlled magnetic field that can be used in many forms.
  • The most common use of solenoid is done in the pinball game.
  • The Flipper solenoid that uses the two coil are used in the mechanism of pinball machines.
  • One coil of the solenoid is supplied with high electric current where as other one has the weak current flowing through it.

7. CALCULATE: How much work is done in each of
kifflom [539]
<h3>Answer</h3>

a. 8J

b. 90J

<h3>Notes formula</h3>

W = F × s

W = Work done (J)

F = Force (N)

s = distance (m)

<h3>Known that </h3>

a. F = 4N

s = 2m

b. F = 30N

s = 3m

<h3>Question</h3>

a. W = ..?

b. W = ..?

<h3>Way to do it</h3>

a. W = F × s

= 4N × 2m = 8J

b. W = F × s

= 30N × 3m = 90J

Raw sewage is raised vertically by 5.49m in the amountof
uranmaximum [27]

Answer:

          P = 1235.7646 W

Explanation:

Given data:

height of raised sewage = 5.49 m

rate of sewage =1.89*10^6 lt/day

density of sewage = 1.050 kg/m^3

power is written as

P = \frac{work}{time}

work  = m g h

m - mass = ( \rho V)

  h -height

mass lifted per day = ( 1.89*10^6)(1.050)

                              = 1984500 kg

time = 24 hours* 3600 seconds per hour

powerP = \frac{( 1984500)(9.8)( 5.49)}{(24)(3600)}

          P = 1235.7646 W

The dimensions of aluminum foil in a box for sale in super markets are 66 2/3 yards by 12 inches. the mass of the foil is 0.83 k
disa [49]

Length of the sheet is given as

L = \frac{200}{3} yards = 6096 cm

width of the sheet is given as

w = 12 inches = 30.48 cm

now let say its thickness is "t"

so the volume of the sheet is given as

V = L*w*t

V = 6096*30.48* t

V = 185806.08*t cm^3

mass of the sheet is given as

m = 0.83 kg = 830 gram

now we have

density = \frac{mass}{volume}

2.70 = \frac{830}{185806.08*t}

by solving above we have

t = 1.65 * 10^{-3} cm

so the thickness of sheet will be above
