Answer:
ΔP = 986 Kpa
Explanation:
The solution is given in the pictures below
Answer:
GIVEN
u is 40m/s and v=60m/s
time is 4s
therefore acceleration =60-40/4
=20/4=5m/s^2
b)next 2 sec=70m/s
Explanation :
In Newton's prism experiment, a ray of white sunlight is passed to the prism. It is observed that the light gets refracted at different angles and different colors spread.
Sunlight is made up of seven colors. The colors are the same as the colors seen in the rainbow. The colors are :
- Violet
- Indigo
- Blue
- Green
- Yellow
- Orange
- Red
So, the correct option is (c) " White sunlight is made up of all the colors of the visible spectrum ".
Answer:
a) 6 m/s
b) 14 m/s
Explanation:
Acceleration is change in velocity over change in time.
a) a = Δv / Δt
2 m/s² = (v − 4 m/s) / 1 s
v = 6 m/s
b) a = Δv / Δt
2 m/s² = (v − 4 m/s) / 5 s
v = 14 m/s
