A block (mass 9.0 kg) is released from rest on a frictionless slope angled at 37° to the horizontal. Draw a diagram with labelle
d vectors for forces/acceleration. What is the block's acceleration?
1 answer:
Answer:
Force diagram is attached here.
Acceleration of the mass down the inclined plane is independent of its mass.
ma = mg sin 37
or Acceleration = a = g sin 37 = 5.9 m/s/s.
Explanation:
The object sliding down the inclined plane has several forces acting on it.
Forces are labelled here as 1, 2, 3, 4.
Force 1 = Normal force that acts at right angles to the inclined surface.
Force 2 : Parallel component of the gravitational force
= mg sin 37.
Force 3: Mass x Acceleration due to gravity = Weight
This is the gravity force that acts perpendicular to the
floor or ground.
Force 4 : Perpendicular component of the gravitational force = mg cos 37.

Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to
and
is constant in magnitude and direction therefore:
Part A)
initially the flux is
after the interval
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
