Answer:
The angle of incidence is equal to the angle of reflection.
Explanation:
yes.
Distance = (speed) x (time)
Distance = (3 x 10⁸ meter/second) x (1 hour)
Distance = 3 x 10⁸ meter-hour per second
Distance = 3 x 10⁵ kilometer-hour per second
Hmmm. That answer is perfectly correct and totally useless. We have no idea how far one meter-hour per second is. It's a unit we never use. We'd better convert the answer to a unit of length that we use every day.
(3 x 10⁵ km-hour/sec) x (3,600 sec/hour) =
(3 x 10⁵ x 3,600) (km-hour-sec/hour-sec) =
1.08 x 10⁹ km
THAT's it ! A pulse of light in vacuum travels 1.08 billion km in one hour.
Answer:
D
Explanation:
You should compare your results and data with your original hypothesis. It is okay to have a hypothesis that was shown to be false. That's science. Things do not always work out. You can always discuss what you could have done differently and things that went wrong. There is no right answer in science!
Given data
mass (m) =8 Kg ,
speed (v) =10 m/s ,
time (t) = 5 s
determine magnitude of force (Fnet) = ?
we knoe that
Fnet = m.a
= 8 × (v/t) since a = v/t
= 8 × (10/5)
= 16 N
<em>Magnitude of net force is 16 N</em>
Nuclear power plants in New Jersey are:
- Hope Creek,
- Oyster Creek,
- Salem.
Oyster Creek is the oldest. It was built in 1969. Salem was built in 1977 and 1979 ( the 2nd unit ). Hope Creek was built in 1986.
Answer: There are 3 nuclear plants in New Jersey.
