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
Answer:
this description is valid for mediadle displacement, bone is an acceptable description
Explanation:
The description of a person's position must be done with a position vector. These vectors must have magnitude, a given direction and a starting point.
In the description this has a starting point corner NO of pine and 675.
Each displacement occurs with respect to the previous one, indicating the magnitude of the displacement and its direction.
After analyzing this description is valid for mediadle displacement, bone is an acceptable description

<u>Answer</u>
C.) 1.0 x 10^2 Newton’s
<u>Explanation</u>
The Newton's second law of motion states that, the rate of change of momentum is proportional to the force producing it.
∴ F = (mv- mu)/t
Ft = mv - mu.
The quantity Ft is called the impulse.
Ft = 0.30 Newton seconds
but t = 3.0 x 10⁻³ seconds
Ft = 0.30 Ns
F × 3.0 x 10⁻³ = 0.30 Ns
F = 0.30 / (3.0 x 10⁻³)
= 100 N
Answer = C.) 1.0 x 10^2 Newton’s
