Answer:
I believe that the correct answer is D. reference point.
Answer:
All three pendulum will attain same velocity
Explanation:
All three pendulum will attain same velocity irrespective of their mass difference in isolated system (means where air drag are negligible) and at same length
As you know when velocity is calculated we can not take mass into account.
Answer:
66.6 kg
Explanation:
The weight of a person at Earth's surface is given by

where
m is the mass of the person
is the acceleration of gravity
The person in the problem has a weight of
W = 653 N
Therefore, we can rearrange the equation to find his mass:

V=IR (voltage equals current<span> times </span>resistance<span>). So </span>if<span> the voltage </span>increases<span>, then the </span>current increases<span> provided that the </span>resistance remains constant<span>.</span>
Answer:
This whole concept depends on the depends on the direction of propagation of the surface wave or displacement of wave such that if its in direction of wave velocity its said to features of longitudinal wave and if its in direction at 90° to wave velocity its said to have transverse features
