Answer:
Sirius
Explanation:
On the HR diagram Sirius is the closet.
<span>One of the methods that best
describe the reduction of energy is energy conservation. It is the usage of
less energy service that it usually utilizes. An example is using bike for
transportation instead of a car to save fuel. The answer is letter B. It is not
energy efficiency because it represents how efficient a substance can convert work
at 100%. It is not reservation because there is no term for it. It is not
energy holding because it defines the how much energy the body can hold.</span>
Answer: Resonance in sound is when one object is vibrating at the same frequency to the second object of forces to the second frequency.
Explanation:
"Acoustic resonance is a phenomenon in which an acoustic system amplifies sound waves whose frequency matches one of its own natural frequencies of vibration (its resonance frequencies)." wikipedia I hope this helps you!
We can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
<h3>What is torque</h3>
The torque experienced by an object a given position is the product of the applied force and the perpendicular distance of the object.
When 5 kg mass is at 2 m on the left, another 5 kg at 2 m on the right will balance it.
<h3>Position of 10 kg mass on the right</h3>
Apply principle of moment
<h3>Net torque</h3>
<h3>Position of the 20 kg mass</h3>
<h3>Net torque</h3>
Thus, we can conclude that as the mass on the right increases, the distance of the mass towards the right decreases. Also when the two masses balance, the net torque is zero.
