The horizontal motion of a launched projectile affects its vertical motion is false
Answer: False
<u>Explanation:
</u>
As the trajectory falls on a plane, all the components like displacement, velocity can be classified in two components termed as horizontal and vertical component.
In a projectile motion, the horizontal components of displacement and velocity remains constant and there is change only in the vertical component of displacement and velocity.
Both components are not dependent to each other. So, the horizontal motions of a launched projectile does not affect its vertical motion.
Answer:
the frequency is the fundamental and distance is L = ¼ λ
Explanation:
This problem is a phenomenon of resonance between the frequency of the tuning fork and the tube with one end open and the other end closed, in this case at the closed end you have a node and the open end a belly, so the wavelength is the basis is
λ = 4 L
In this case L = 19.4 cm = 0.194 m
let's use the relationship between wave speed and wavelength frequency and
v = λ f
where the frequency is f = 440 Hz
v = 4 L f
let's calculate
v = 4 0.194 440
v = 341.44 m / s
so the frequency is the fundamental and distance is
L = ¼ λ
Answer:
Mass, acceleration
Explanation:
Force= Mass (kg) *acceleration (m/s^2)
