Answer:
F = 9.675Hz
Explanation:
pls for certain reasons let us make
- wavelength = $
- frequency = F
- V = velocity
3 loops : 6$/4 = L
6$/4 = 2
$ = 4/3 = 1.333
V = F x $
F = V/$
F = 12.9/1.333 = 9.675Hz
F = 9.675Hz
Hey :)
The water potential of pure water<span> in an open container is zero because there is no solute and the pressure in the container is zero</span>
Answer:
In a collision, the velocity change is always computed by subtracting the initial velocity value from the final velocity value. If an object is moving in one direction before a collision and rebounds or somehow changes direction, then its velocity after the collision has the opposite direction as before.
Answer:2.81 m
Explanation:
Given
speed(u)=13 m/s
dart strikes 0.23 m below
i.e. vertical distance traveled by dart is 0.23 m
considering dart motion similar to Projectile
Horizontal distance travel by dart =u\times t
