Explanation:
using
v = f × lambda
lambda = v/f
v = 343.06m/s to cm/s
343.06 × 100
34306.00cm/s
f = 493.88 Hz
lambda = (34306/493.88) cm/s÷Hz
lambda = 69.46cm
Displacement in Space
It is the length of a body's real route. It is the shortest distance between the body's final and beginning positions.
It's a number with a scalar value. It's a quantity with a vector.
It can't possibly be negative. It might be a negative number, a zero number, or a positive number.
Answer:
I don't exactly understand this but the child should hear a beep lower than 500 hz when he/she moves the car further away. If you don't find my answer appealing sorry but I don't do physics.
Explanation:
Alright let's start this off with our basic equation!
Accerlation (
a) = ?
Initial velocity (
V1)= 60 mph = 88 ft/s (because we HAVE to convert mph to ft/s to match time)
Final velocity (
V2) = 0 ft/s because the car stops
Time (
t) = 4 seconds
a =
a =
a =
a = -22
Therefore, your acceleration is -22 ft/s² !! Hope this helped and was one of the branliest answers :')
