Answer:
The material stretched across the drum vibrates to produce the sound waves.
Explanation:
A drum is one of the oldest musical instrument made by man. It is made of a hollow body over which a material such as skin is stretched. When a drum is struck with a stick, the material vibrates up and down. This makes the air above the drum to contract and relax rhythmically resulting in soundwaves. The soundwaves travel through air to reach our ears where they are heard.
The quality of sound produced by a drum is affected by its shape. A larger drum produces a lower pitched sound.
No that is false
Because its a organism. Which means at one point it was a live. It just died. You cant die if you were never alive. So that means that at one time was living.
But nonliving thing in science is like a piece of plastic cant breath eat die non living
If this was helpful pls mark be as brainliest!!!!!!!!
Answer:
0.027m
Explanation:
the bolt loses contact with the piston only when acceleration due to gravity equals acceleration of piston
ω² * A = g where ω is angular velocity, A amplitude, g acceleration due to gravity
ω is given by 2πf, ω² is 4π²f²
A= g/4π²f² depending on the value of g used either 10m/s² or 9.8m/s²,
i used 10m/s² in this answer
Answer:
Given:
Radius of curvature (R) of a spherical mirror = 20
To Find:
Focal length (f)
Explanation:
Formula:
Substituting value of R in the equation:
The answer is false. The speed of the astronaut cancels out the force of gravity, causing a 'stationary freefall'. While under these effects, it is not required for an astronaut to 'strengthen' his body.
