At an outdoor market, a bunch of bananas is set on a spring scale to measure the weight. The spring sets the full bunch of banan
olga55 [171]

Answer:

Mass of banana is 1.12 Kg

Explanation:

Step 1: Determine the equation of speed of an object moving in an harmonic motion

Speed of moving in an harmonic motion is given by

v = \sqrt{\frac{k}{m} (A^2 -x^2)} \\

Here, v represents the speed of the object in harmonic motion, k is the springs constant, m is the mass of the object, A is the amplitude, and x is the position.

In this question , x = 0 because only at this position maximum speed occurs

So the simplified equation becomes -

v = \sqrt{(\frac{k}{m} * A)}

OR

m = \frac{kA^2}{v_(max)^2}

Substituting the given values in above equation we get -

Assume spring constant is 16N/m

m = \frac{16 * 0.14}{2} \\m = 1.12

Mass of banana is 1.12 Kg

What happens to the amount of energy present when it is moved from one form to another
Jet001 [13]
The amount of energy is ALWAYS conserved based on the law of conservation of energy. Therefore, the amount of energy will remain the same.

HELP ASAP!!!!! ILL MARK YOU BRAINLIEST!
Julli [10]
Hello! Sorry this is a little late!

The answer to your question would best be option C, y<span>es, because electric charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.

I just took this test, and can 100% confirm this is the correct answer!

Hope this helps, and have a great day! :)</span>
