Answer:

Explanation:
The angular momentum of the pulsar is given by:

where
is the mass of the pulsar
is the radius
is the angular speed
Given the period of the pulsar,
, the angular speed is given by

And so, the angular momentum is

Answer:
The value of gauge pressure at outlet = -38557.224 pascal
Explanation:
Apply Bernoulli' s Equation
+
+
=
+
+
--------------(1)
Where
= Gauge pressure at inlet = 3.70105 pascal
= velocity at inlet = 2.4 
= Gauge pressure at outlet = we have to calculate
= velocity at outlet = 3.5 
= 3.6 m
Put all the values in equation (1) we get,
⇒
+
=
+
+ 3.6
⇒ 0.294 =
+ 0.6244 + 3.6
⇒
= 0.294 - 0.6244 - 3.6
⇒
= - 3.9304
⇒
= - 38557.224 pascal
This is the value of gauge pressure at outlet.
More work is done when one man lifts the weight using a pulley. Option C is correct.
<h3>What is mechanical advantage ?</h3>
Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of forces in levers and pulley.
It is an effective way of amplify the force in simple machines like lever The theoretical mechanical advantage is defined as the ratio of the force responsible for the useful work in the system to the applied force.
More work is done when one man lifts the weight using a pulley. With the pulley, the mechanical advantage is increasing.
Hence, option C is correct.
