Answer:
as it travel through the space it behave like a wave and has an oscillating electric field components and an oscillating magnetic field
-- During the time the ball is flying from the high roof to the low roof,
it's going to fall (100-25) = 75 meters.
How long does it take an object dropped from rest to fall 75 meters ?
Distance = (1/2) · (gravity) · (time)²
75 m = (4.9 m/s²) · (time)²
Time² = (75 m) / (4.9 m/s²)
Time² = 15.31 sec²
Time = √(15.31 sec²) = 3.91 seconds
So the ball has to cover the horizontal distance of 20 meters
in 3.91 seconds.
Distance = (speed) · (time)
20 m = (speed) · (3.91 sec)
Speed = (20 m) / (3.91 sec)
Speed = 5.11 m/s
Answer:
Explanation:
Given
--- Ken's share
Required
The fraction each got
Since they both shared a cake, we have:
Substitute:
Factorize
Divide both sides by 3
Recall that:
D do.
All 3 resistors are connected directly across the battery.
