Answer:
The best single equation in order to fin the acceleration is
Explanation:
The best single equation in order to find the acceleration is the following kinematics equation:
As the rocket start from the rest, the initial velocity value is zero. Then the acceleration value is:
Answer:
change in entropy is - 5.7627 J/K
Explanation:
Given data
temperature = 22.0°C = 22 + 273 = 295 K
work is done = 1700 J
to find out
change in entropy
solution
we know that change in entropy = Q /T ......1
from 1st law of thermodynamic we know
Q =W for change in internal energy = 0
Q = -1700 J
so from equation 1
change in entropy = - 1700 / 295
change in entropy = - 5.7627
so change in entropy is - 5.7627 J/K
It would be potential energy because it is not moving. <span />
The frequency of a tuning fork that takes2.50×10⁻³ s to complete one oscillation would be 400 Hz.
<h3>What is the frequency?</h3>
It can be defined as the number of cycles completed per second. It is represented in hertz and inversely proportional to the wavelength.
As given in the problem a tuning fork takes 2.50×10⁻³ s to complete one oscillation.
Frequency = 1/time period of the oscillation
Frequency of the tuning fork = 1/time period
=1/2.50×10⁻³
=400 Hz
Thus the frequency of a tuning fork comes out to be 400 Hz.
