Vietually every electronic device in widespread use contains some form of capacitors .used to store electricity capacitor aften help computer avoid losing their memory when the batteries an being recharged other device such as amplifiers for car steroeos contain capacitor that store energy until it is nedded by the amplifier motiondetector use capacitor to help achieve the proper timing of the until circuit.
Answer:
a.v=u+v/2
a.v=s/t
combining two equation we get,
u+v/2=s/t
(u+v)t/2=s
(u+v)t/2=s
{u+(u+at)}t/2=s
(u+u+at)t/2=s
(2u+at)t/2=s
2ut+at^2/2=s
2ut/2+at^2/2=s
UT +1/2at^2=s
proved
a=v-u/t
at=v-u
u+at=v
Answer:
3 up 1 across is the answer
Explanation:
Step one: find the Y intercept( Where the line cuts the y-axis)
X = 0
Y = 3(0) (p.s cross out the (o)
y = 2
Step 2: find the gradient (slope of the line)
rise = 3

Answer:
19.01 N
Explanation:
F = Force being applied to the crate = 45 N
= Angle at which the force is being applied = 
Horizontal component of force is given by
The horizontal component of the force acting on the crate is 19.01 N.
-- The net effective resistance of 10-ohms and 4-ohms
in series is 14 ohms.
-- The current in the series loop is I = E/R = 42V/14-ohms = 3 amperes.
