If one oscillation has 5.8 times the energy of the second one of equal frequency and mass, 2.4:1 is the ratio of their amplitudes.
Oscillation is defined as the process of repeating fluctuations of a quantity or measure around its time equilibrium value. Oscillation can also be defined as the periodic fluctuation of matter between two values or about their average.
The definition of happiness is someone or something that makes you feel great joy or pleasure. An example of good luck is someone who wins the lottery. An example of happiness is a laughing baby. Besides making you feel better, positive emotions are good for your brain and body. It lowers stress hormones, relieves anxiety and depression, and strengthens the immune system. Feeling positive emotions every day has a huge impact on our well-being and health.

Answer is D. Nearsightedness is when a person can see near, but not far. Everything appears blurry from far away, but as you get close to it, it becomes more focused
Answer:
159 N
Explanation:
The force of friction, Fr is a product of coefficient of feiction and the normal force. Therefore, Fr=uN where N is the normal force and u is coefficient of friction. Here, we have two coefficients of friction but since it is sliding, then we use coefficient of kinetic energy. Substituting 0.25 for u and 636 N for N then
Fr=0.25*636=159 N
Therefore, the force of friction is equivalent to 159 N
Answer:
6.77 m/s
Explanation:
Acceleration = Force/mass;
The block is accelerated by 13/6.4 m/s^2 for 2.1s from an initial velocity of 2.5m/s.
Applying the equation of motion:
Vf=Vi + at
Where Vf is the final velocity, Vi is the initial velocity, a is the acceleration and t is the time for which the object accelerates.
<h3>Vf= 2.5 + ((13/6.4)*2.1);</h3>
