Answer:
Explanation:
Component of force perpendicular to stick
= F Sin 60°
=√3 / 2 F.
Taking torque about the other end
= √3 / 2 F x 1 Nm
Weight of stick = 60 gm
= 60 x 10⁻³ kg
= 60 x 10⁻³ x 9.8 N
= .588 N
This weight will act from the middle point of stick so torque about the
other end
= .588 x 1 Nm
Balancing these two torques we have
.588 = √3 /2 F
F = 0.679 N
I think the answer is false
That is called fully constructive interference.
'C' and 'D' are the same statement, and none of the 3 choices
is good.
Electrical energy is produced in a generator, a solar panel, or
a battery, not in things with resistance.
From the generator or battery, current flows through a circuit of
one or more components.
The greater the resistance of a component, the more energy is
LOST as the current flows through it. The component dissipates
the energy in the form of heat.
