Explanation:
(a) Formula to calculate the capacitance is as follows.
Now, putting the given values into the above formula as follows.
= 0.291
or, 
= ln (0.291)
= -1.23
C = 0.729 F
Hence, the value of capacitance is 0.729 F.
(b) Formula to calculate the constant of circuit is as follows.
T = 
= 
= 2.259 sec
Therefore, the time constant of the circuit is 2.259 sec.
Answer:
I'm not completely sure, but I believe the first and third of the three are mechanical.
Explanation:
Chemical potential isn't moving or about to go into motion. It can't be mechanical.
Answer:193.90 m/s
Explanation:
Given
launch angle 
launch velocity 
Horizontal velocity of the shell after 
time of flight of Projectile 
i.e. projectile is declining as 
but horizontal component of velocity will remain same as there is no opposing force in horizontal direction
Horizontal component of velocity is
Answer:
the answer is b
Explanation:
gravity pulls you down so on a scale you will weigh more. less gravity you will weigh less.
