Explanation:
Consider a dipole having magnetic moment 'm' is placed in magnetic field then the torque exerted by the field on the dipole is
Now to rotate the dipole in the field to its final position the work required to be done is
Minimum energy mB is for the case when m is anti parallel to B.
Minimum energy -mB is for the case when m is parallel to B.
Answer:
The required new pressure is 775 mm hg.
Explanation:
We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.
We have to find the required new pressure.
Let the required new pressure be ''.
As we know that Boyle's law formula states that;
where, = original pressure of gas in the container = 310 mm hg
= required new pressure
= volume of gas in the container = 185 ml
= desired new volume of the gas = 74 ml
So,
= 775 mm hg
Hence, the required new pressure is 775 mm hg.
Tension in the rope due to applied force will be given as
angle of applied force with horizontal is 37 degree
displacement along the floor = 6.1 m
so here we can use the formula of work done
now we can plug in all values above
So here work done to pull is given by 691.8 J
