Answer:
hey friend,
an element becomes a positively charged ion when it <em>loses electrons</em>
Answer:
a) 2250 J
b) 0 J
c) 2250 J
Explanation:
a) Since, the process is isochoric
the change in internal energy
Here, n = 0.2 moles
Cv = 12.5 J/mole.K
We have to find T_f so we can use gas equation as
So,
b) Since, the process is isochoric no work shall be done.
c) By first law of thermodynamics we have
Since, Q is positive 2250 J of heat will flow into the system.
Answer:
(A) Impulse will be 1.116 kgm/sec
(B) Force will be equal to 1116 N
Explanation:
We have given mass of the basketball m = 0.120 kg
Initial speed of the ball
Final speed of the ball
(A) Impulse delivered by the ball is equal to the change in momentum
So impulse will be equal to
So impulse will be 1.116 kgm/sec
(B) Time is given for which force is exerted
We know that impulse is equal to
F = 1116 N
Steam engine is not an example of a heating appliance
