Answer:
Options d and e
Explanation:
The pendulum which will be set in motion are those which their natural frequency is equal to the frequency of oscillation of the beam.
We can get the length of the pendulums likely to oscillate with the formula;
where g=9.8m/s
ω= 2rad/s to 4rad/sec
when ω= 2rad/sec
L = 2.45m
when ω= 4rad/sec
L = 9.8/16
L=0.6125m
L is between 0.6125m and 2.45m.
This means only pendulum lengths in this range will oscillate.Therefore pendulums with length 0.8m and 1.2m will be strongly set in motion.
Have a great day ahead
That distance is the definition of 1 AU.
Greater than.........that,s th answer
THE MOTION IS GOOD BECAUSE IT MAKES THE BATTER IT THE BALL AND THE BATTER LINES UP THE BALL AND BAT AND HE HITS IT
<span>MASS OF THE STAR IS 10 TIMES OF THE SUN.
M = 10Msun
HERE, Msun IS THE MASS OF THE SUN.
THE RELATION BETWEEN THE LUMINOSITY AND THE MASS OF THE STAR IS
L = M3.5
HERE, M IS THE MASS OF THE STAR,
SUBSTITUTE 10Msun for M
L = (10Msun)3.5
=> (10 3.5)Msun3.5
from the above result, it is clear that the luminosity of the star is approximately 10 times that of the sn. Therefore the luminosity of the star is 10 solar units.</span>
