What medium does sound travel through the quickest and why

Physics

crimeas [40]3 years ago

Sound travels through all mediums solid, liquid, and gas. Because sound is a vibration it will travel fastest through solids. This is because the vibrations that make up sound are carried from one place to another by neighboring molecules vibrating against one another. The density of the solid is higher than liquid and gas which means the molecules are more tightly packed and the vibration can pass from one to the next more quickly.

How much work do you do on a 15 N book in lifting it straight up for a distance of<br> 0.40 meters?
astra-53 [7]

Answer:

Work done, W = 6 J

Explanation:

It is given that,

Force of gravity acting on the book, weight of the book is 15 N

We need to find the work done in lifting the book straight up for a distance of  0.4 meters.

The weight of the book is acting in downward direction and the book is lifted straight up, it means angle between them is 180 degrees. Work done is given by :

W=Fd\cos180\\\\W=15\times 0.4\times \cos180\\\\W=-6\ J

So, the magnitude of work done in lifting the book is 6 joules.

nydimaria [60]

Answer:

Velocity

Explanation:

We finds that the winds are coming from the west at 15 miles per hour. This information shows the velocity of the wind. Since, velocity is a vector quantity. It has both magnitude and direction. 15 miles per hour shows the speed of wind and west shows the direction of wind motion.

Hence, the given information describes wind velocity.

A 36-g ball at the end of a string is swung in a vertical circle with a radius of 19 cm. The tangential velocity is 200.0 cm/s.
STALIN [3.7K]

Answer:

0.758 N

Explanation:

mass of ball, = 36 g = 0.036 kg

radius, r = 19 cm = 0.19 m

tangential velocity, v = 200 cm / s = 2 m /s

The tension is the string is equal to the centripetal force acting on the ball.

The centripetal force acting on the ball is given by

T=\frac{mv^{2}}{r}

T=\frac{0.036 \times 2 \times 2}{0.19}

T = 0.758 N

Thus, the tension in the string is given by 0.758 N.
