Answer:
i think the answer is letter c
Answer: Technician A is correct
Explanation:
Technician B is wrong because decrease in resistance will surely cause increase in the flow of current.
As temperature rises, the number of phonons increases and with it the likelihood that the electrons and phonons will collide. Thus when temperature goes up, resistance
goes up. For some materials, resistivity is a linear function of temperature. The resistivity of a conductor increases with temperature.
I would say the answer is 3 because by falling technically the ball would be kind of moving in the air. Plus potential energy is when for example a soccer ball isnt moving
Answer:
(A) Time period T = 6.28 SEC
(B) At highest point fore is - 575.83 N
(B) At lowest point force is 1050.97 N
Explanation:
We have given that mass m = 83 kg
Radius r = 13 m
Speed v = 6.10 m/sec
(A) Time period of the motion is given by
(b) Net force is given by
Force due to gravity
At highest point
(B) At lowest point
