Use the displacement law, peak wavelength = 0.0029/T =0.0029/30000 = 97nm
Answer:
Explanation:
Descriptive statistics statistics are measures that summarize the characteristics of a sample.

Given :
The pink car has a velocity of 4.4 m/s to the right while the blue car has a velocity of 6.8 m/s to the left.
To Find :
If the two cars crashed and stuck together, what would their combined momentum be afterwards and what direction would they be moving.
Solution :
Let, combined velocity of the car is v.
Also, let us assume that mass of both the cars are equal and it is m.
By conservation of momentum :
Initial momentum = Final momentum
m( 6.8 ) - m( 4.4 ) = 2mv
2mv =2.4m
v = 1.2 m/s
Therefore, the velocity of combined car after crash is 1.2 m/s .
- "Gravity is a universal attraction between any two objects with mass. Every object in the universe is affected by the force of gravity. The two factors that affect the magnitude of gravity are the mass of the attracted objects and the distance between them. The greater the masses the greater the gravitational force between two objects."
The time measured is 25 seconds. The error in the measurement is 0.2 seconds. The % error is therefore
(0.2/25)x100 = 0.8%.
The period of one oscillation is 25/20=1.25 seconds. The error in the period is 0.8/100 x 1.25 = 0.01 second.

ie period = 1.25 +/- 0.01 s.
