Answer
The Little Bee will have a greater force of 12N
<u>Explanation</u>
As we know that Force is equal to the product of mass and acceleration (F=ma)
The Force with which the Big Bee will hit the windshield = (5kg x 2m/s^2)
Force of Big Bee= 10 Newton (N)
The Force with which the Little Bee will hit the windshield = (3kg x 4m/s^2)
Force of Little Bee = 12N
Hence, the little bee will hit the windshield with a greater force.
Answer:
0.12 mm ; 140.50 rad/m ; 628.32 rad/sec ; +
Explanation:
Given the wave equation of the form :
y(x, t) = ym sin(kx ± ωt)
Mas per unit length (u) = 5 g/cm = (5÷1000)kg / 0.01m) = 0.005kg/0.01m = 0.5kg/m
Tension, T = 10 N
Amplitude, A = 0.12 mm
Frequency, F = 100 Hz
Comparing with the general wave equation :
y = Asin(kx ± ωt)
A = amplitude = ym = 0.12 mm
2.) k = 2π / λ
Recall :
v = fλ
v = sqrt(T/u) = sqrt(10/0.5) = sqrt(20) = 4.472
λ = v/ f = 4.472 / 100 = 0.04472
Hence,
k = (2 * π) / 0.04472
k = 140.50 rad/m
3.) Angular frequency, ω
ω = 2πf = 2 * 3.14 * 100 = 628.32 rad/sec
4.) sign is +ve
Direction of wave propagation as given is in the negative x axis
Answer:
This is the simplified definition.
Explanation:
The main goal of physics is to explain how things move in space and time and understand how the universe behaves.
