I think it would be by the change in speed
For example if light travels from air to water it will slow down causing it to travel at a different angle/direction
Answer:
1.) True
2.) True
3.) False
Explanation:
1.) Oxidizing agents can convert co into co2.
This is true
Carbon monoxide burns in the oxygen to produce carbon dioxide
2.) A reducing agent gets oxidized as it reacts.
This is true
Because it loses electrons and is oxidized in a chemical reaction.
3.) If something is reduced, it is formally losing electrons.
This is false.
If something is reduced, it is gaining electrons.
Answer:
t = 10.1 s
d = 2020 m
Explanation:
Time to drop from vertical rest
h = ½gt²
t = √(2h/g) = √(2(500)/9.8) = 10.1 s
d = vt = 200(10.1) = 2020 m
The old electricity meters with disk using sapphire bearings for friction to be minimal to not aggravate metering
Given
The projectile is in air for a time of t=8 sec
To find
The time it takes to reach the highest point
Explanation
A projectile moves up to the highest point and then again moves down following a parabolic path.
So it will reach the highest point at a time half the time it requires to follow teh parabolic path.
The time taken to reach the highest point is 4 sec
Conclusion
The time taken is 4 sec.
