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.
<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

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
work = m g h
h -height
mass lifted per day 
= 1984500 kg
time = 24 hours* 3600 seconds per hour
power
P = 1235.7646 W

Length of the sheet is given as
width of the sheet is given as
now let say its thickness is "t"
so the volume of the sheet is given as
mass of the sheet is given as
now we have
by solving above we have
so the thickness of sheet will be above
