Answer:
The work done will be 57.15 J
Explanation:
Given that,
Mass = 12 kg
Distance = 3 m
Force = 22 N
Angle = 30°
We need to calculate the work done
The work done is defined as,
Where, F = force
d = displacement
Put the value into the formula
Hence, The work done will be 57.15 J
Answer:
magnitude of the induced emf in the coil is 0.0153 V
Explanation:
Given data
no of turns = 20
area = 0.0015 m²
magnitude B1 = 4.91 T/s
magnitude B2 = 5.42 T/s
to find out
the magnitude of the induced emf in the coil
solution
we know here
emf = -n A d∅ /dt
so here n = 20 and
A = 0.0015
and d∅ = B2 - B1 = 5.42 - 4.91
d∅ = 0.51 T and dt at 1 sec
so put all value
emf = -n A d∅ /dt
emf = -20 (0.0015) 0.51 / 1
emf = - 0.0153
so magnitude of the induced emf in the coil is 0.0153 V
Answer:
7
g/cm³
Explanation:
The formula for density is
. Let's apply the formula to the question:
= 7
g/cm³
on a given inclined we know that net force is given by

here we know that

so here we have


so here acceleration depends directly on angle of inclination
now we also know that if height of the inclined is H and its length is L
then we can write

so the acceleration is given as

so acceleration also depends directly on height of the inclined plane
Where the displacement is a maximum the pressure is a minimum.
Where the displacement is zero, the pressure is a maximum.
