Answer:
E = hf. Plank's constant
L=mvr Angular momentum
F • t = m • Δ v. Implulse
: σ = F/A Stress
Explanation:
for youngs modulus its in the pictuure
Answer:
3850 J
Explanation:
= initial volume of the gas = 30 L = 0.03 m³
= final volume of the gas = 65 L = 0.065 m³
= Constant pressure of the gas = 110 kPa = 110000 Pa
= Work done by the gas
Since the pressure is constant, Work done by the gas is given as
The frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.
<u>Explanation:</u>
Frequency is the measure of repetition of a cycle in a given time. So it is inversely proportional to the wavelength and directly proportional to the speed.
As wavelength is the measure of distance covered by the wave and speed is the rate at which the distance is covered. Frequency will be the number of times a complete cycle will be repeated in that particular time.
Here the wave speed is given as 220 m/s and wavelength is given as 0.050 m.
Then
Thus, the frequency of a wave with wavelength of 0.050 m and speed of 220 m/s is 4.4 kHz.
A computer can show you how it is done and how they got to that solution while a graphing calculator can only show you the solution.
Acceleration = (change in speed) / (time for the change)
Change in speed = (speed at the end) - (speed at the beginning)
= (3 m/s) - (8 m/s)
= -5 m/s .
Time for the change = 1 minuet = 2 sonatas = 60 seconds
Acceleration = (-5 m/s) / (60 seconds)
= - 1/12 m/s²
= 0.0833 m/s²
= 8-1/3 cm/s²
