Answer:
7.894 Hours.
Explanation:
Based on information number hours that this battery will last with give load has mathematical relation of.
with load 60A t = 1h, 30A t = 2h so on and forth.
two head lights draw total current of 2x3.8A = 7.6A.
putting this in above relation gives.
.
That is how long will it be before battery is dead.
Explanation:
The waveform expression is given by :
...........(1)
Where
y is the position
t is the time in seconds
The general waveform equation is given by :
..........(2)
Where
On comparing equation (1) and (2) we get :
f = 93.10 Hz
Time period,
T = 0.010 s
Phase constant,
Hence, this is the required solution.
Answer:
a=
Explanation:
The net force, of the box is expressed as a product of acceleration and mass hence
where m is mass and a is acceleration
Making a the subject, a=
From the attached sketch,
∑ where
is frictional force and
is horizontal angle
Substituting ∑ as
in the equation where we made a the subject
a=
Since we’re given the value of F as 240N, as 41.5N,
as
and mass m as 30kg
a=
