: The maximum theoretical efficiency of a Carnot engine operating between reservoirs at the steam point and at room temperature
Hunter-Best [27]

Answer:

The value is   \eta  =  0.2145  or  21.45%

Explanation:

From the question we are told that

    The first reservoir is at steam point  T_s =  100^o C =  100 + 273 = 373 \ K  

    The  second reservoir is at room temperature T_r  =  20^o C = 293 \ K

Generally the  maximum theoretical efficiency of a Carnot engine  is mathematically evaluated as

     \eta  =  1- \frac{T_r}{T_s}

=>    1 - \frac{ 293}{373}

=>    \eta  =  0.2145

A golf ball traveling 3m/s to the right collides in a head-on collision with a stationary bowling ball in a friction-free enviro
Vladimir79 [104]

Answer: equal to 3 m/s

Explanation:

Speed of golf ball will be equal to 3 m/s because in Perfect Elastic Collision Energy is conserved .

So speed of golf ball will be same in order to Satisfy

Initial Kinetic Energy =Final Kinetic Energy

Considering Bowling ball remains at rest after collision other wise some energy will also be acquired by bowling ball which automatically decreases the amount of Kinetic Energy of golf ball resulting its speed to decrease by some extent.

Which of the following will cause an induced current in a coil of wire? Which of the following will cause an induced current in
svp [43]

Answer:

a magnet being moved into or out of the coil

Explanation:

Electromagnetic induction on a coil of wire depends on relative motion between the wire and a magnetic field. If there is no relative motion between the magnet and the coil, no current is included on the wire. This implies that a stationary magnet around a coil of wire will not produce induced current on a stationary conductor or wire.

Summarily, whenever a conductor is placed in a changing magnetic field, current is induced on the conductor.
