Why does the energy of a sound wave decrease over time

Answers

Answer 1

Answer: Sound is a longitudinal wave that carries energy. Sound needs a medium to propagate through (this means that sound cannot propagate in vacuum).

The medium usually determines the speed of the wave travelling through it.

As the sound waves travel in a medium, this medium begins to decrease, therefore, the energy of the sound also decreases.

Which of the following is NOT supported by Newton's Second Law?1 The mass of an object will change depending on the force acting on it

2 The greater the force applied on an object, the greater it's acceleration

3 You can find the mass of an object if you know it's acceleration and the forces acting on it

4 Force is equal to the product of mass and acceleration

Answers

Answer:

1. The mass will change depending on the force.

Explanation:

We know that the newton's second law of motion gives the relation between the mass (m) of an object, force (F) applied and the corresponding measure of acceleration (a) of the object. This can be expressed in the form of an equation:

F = ma

Thus force is the product of mass and acceleration. Using this equation we can derive mass of an object, if acceleration and force values are known.

In the given equation, mass is a constant value and mass will not change in any case. Therefore force is directly proportional to amount object will be accelerated. With the increase in force applied on object, amount the object accelerated will increase and vice versa

contrast the force of gravity between these pairs of objects: 1-kg mass and a 2-kg mass that are 1 m apart; a 1-kg mass and a 2-kg mass that are 2 m apart; and two 2=kg masses that are 1 m apart. helpppppp i dont understand.

Answers

force of gravitation between two different masses is given by

$F = (Gm_1m_2)/(r^2)$

here in first case we will have

$F_1 = (G(1kg)(2kg))/((1m)^2)$

$F_1 = 2G$ Newton

another case we have

$F_2 = (G(1kg)(2kg))/((2m)^2)$

$F_2 = (G)/(2)$ Newton

another case we have

$F_3 =(G(2kg)(2kg))/((1m)^2)$

$F_3 = 4G$ Newton

so the force will be maximum in last case when two 2 kg mass is placed at 1 m distance and minimum force is in second case when 1kg and 2kg mass is placed at 2 m distance

When an object moves, stops moving, changes speed, or changes direction, how do scientists describe that condition?

Answers

Drop "moves" from the list for a moment.

You can also drop "stops moving", because that's included in "changes speed"
(from something to zero).

When an object changes speed or changes direction, that's called "acceleration".

I dropped the first one from the list, because an object can be moving,
and as long as it's speed is constant and it's moving in a straight line,
there's no acceleration.

I think you meant to say "starts moving". That's a change of speed (from zero
to something), so it's also acceleration.
