Answer:
The value is
Explanation:
From the question we are told that
The the peak wavelength is
Generally according to the Wien's displacement law
Here T is the approximate surface temperature of this star in K so
=>
Converting to Fahrenheit ,
=>
Answer:
Option d is the correct option Kinetic energy is minimum while as potential energy is maximum
Explanation:
At the top most point of the flight since it cannot reach any further up in the vertical direction thus the potential energy at this position shall be maximum. Now since the total energy of the projectile is conserved so the remaining kinetic energy shall be minimum at that point so as the sum of the kinetic and potential energies remain constant.
They catch fire with the ohm with the light from the gas with the heat and gas from radiation elects from the chemicals mixed
Length of the pendulum (l) = 2 m
Acceleration due to gravity = g = 9.8 m/s^2
For small amplitude, the pendulum will undergo simple harmonic motion.
Hence, the time period of the pendulum for small amplitude =
Now, plug the values of l and g
T =
T = 2 × 3.14 × 0.451
T = 2.83 seconds
Hence, the time period of the pendulum for small amplitude = 2.83 s
