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.

klemol [59]
A person on Earth would weigh a lot more on the sun due to increased gravity.

The sun is a massive object as compared to the sun. It is assumed that the gravity must be a lot greater as well. It is the strong gravitational pull of the sun that keeps our planets from drifting off into space. No matter where you are the mass of an object will remain constant, so will the energy and the number of atoms they hold. 

The answer is gravity.
