Answer:
I think D. Since a vacuum iswhere gravity is concentrated. not sure
Answer: 0.145 seconds
Explanation:
Given that Roger Clemens could routinely throw a fastball at a horizontal speed of 119.7 m/s. How long did the ball take to reach home plate 17.3 m away
Since the speed is horizontal
Using the formula for speed which is
Speed = distance/time
Where
Speed = 119.7 m/s
Distance covered = 17.3 m
Time is what we are looking for
Substitute all the parameters into the formula
119.7 = 17.3/ time
Make time the subject of formula
Time = 17.3 / 119.7
Time = 0.145 seconds.
Therefore, it will take 0.145 seconds to reach the home plates
On the off chance that u know the condition I = NEVA where N= no. thickness of electrons, E= charge on a solitary electron, V=drift speed ,and A=area of cross-segment.
since the widths are same , the zone of cross-segment must be same and thusly the float speed likewise will be the same
b) as u know current streams from higher to bring down potential.The electrons will spill out of lower potential to higher potential. Higher potential suggests higher potential vitality and accordingly potential vitality must increment.
The energy comes in waves and I forget how, but the waves make the water molecules in teh food spin and that causes friction which warms the food up
