Answer:
Unit Cell
Explanation:
Answer:
Distance covered by B is 4 times distance covered by A
Explanation:
For an object in free fall starting from rest, the distance covered by the object in a time t is
where
s is the distance covered
g is the acceleration due to gravity
t is the time elapsed
In this problem:
- Object A falls through a distance during a time t, so the distance covered by object A is
- Object B falls through a distance during a time 2t, so the distance covered by object B is
So, the distance covered by object B is 4 times the distance covered by object A.
Answer:
52.5 mph
Explanation:
part 1,
speed=40mph
distance= 40×3=120 miles
time= 3 hours
part 2
speed= 60mph
distance= 300 miles
time= 300÷60= 5hours
Average speed= (300+120)÷(5+3) = 52.5mph
per second. What is the absolute index of
refraction of the second medium?
(1) 1.00 (3) 1.75
(2) 0.570 (4) 1.94
