If a 20 gram bird and a 0.001 gram mosquito are moving at the same speed, which has the higher kinetic energy?why?
1 answer:
Answer:
The bird has 20,000 times higher kinetic energy than the mosquito.
Explanation:
The formula for kinetic energy shows that the amount of energy is proportional to the mass:
The velocity of both objects being the same, the mass is the determiner. The ratio of the kinetic energy of the bird and the mosquito then becomes the ratio of their masses, i.e., 0.02kg/0.00001kg. The bird's energy is 20,000 times higher than that of the mosquito. This proportion becomes more believable if you imagine the event of a distracted errant bird colliding with your head, versus a confused mosquito colliding with your head.

The answer to this question is: it depends. It depends on the arrangement of the capacitors in a circuit: it can be either in series or in parallel. The difference is shown in the picture.
Capacitors are like batteries in a way that they store power from the source. It has some rules depending on the type of circuit. For parallel circuits, the voltage across each capacitor is equal. Therefore, V₁=V₂=V₃.
On the other hand, if the capacitors are arranged in series, the voltage across each capacitor should add up to the total voltage of the source. Therefore, V₁+V₂+V₃ = Total Voltage.

Answer:
When we double the angular velocity the maximum acceleration will changes by a factor of 4.
Explanation:
Given the angular frequency of the simple harmonic oscillator is doubled.
We need to find the change in the maximum acceleration of the oscillator.
Now, according to the problem, the angular frequency got doubled.
Let us plug . Then the maximum acceleration will be
We can see, when we double the angular velocity the maximum acceleration will changes by a factor of 4.
