The speed of sound in wood is ____ the speed of sound in water.

pishuonlain [190]

Answer:

greater

Explanation:

the speed of sound in steel is greater than water. the speed of sound in wood is not, In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air, but it takes a lot of energy to start the vibration.

Wood is less dense and force can make a sound.

Why do you keep moving forward when you slam on the brakes of your bike?

g100num [7]

Because the act of braking is an example of negative acceleration.
Example: if the rate of braking was say 2 meters per second^2, and the starting velocity was 10 m/s, it would take 5 seconds to come to a stop(during those 5 seconds you would still be moving).

Two identical billiard balls are rolling toward each other at the same speed. What will be true after they collide head–on?

ioda

My guess is either they come to a stop when they come in contact, or one ball is going to go the opposite direction.

Which quantities below of a solid object on this planet are NOT the same as on Earth?

AysviL [449]

Answer:

Weight, acceleration when it falls vertically, are not same as that of earth.

Explanation:

Weight of the object is given by the product of mass of the object and the acceleration due to gravity of the planet.

So, the weight of object is not same as that on earth.

The mass is defined as the amount of matter contained in the object.

So, the mass of the object is same as that of earth.

The volume of the object is defined as the space occupied by the object.

So, the volume of the object is same as that of earth.

The density is defined as the ratio of mass of the object to its volume.

So, the density of the object is same as that of earth.

The acceleration due to gravity on a planet depends on the mass of planet and radius of planet.

So, the acceleration is not same as that of earth.

The color of the object is its characteristic.

It is same as that of earth.
