Answer:
B v1= 12.5m/s
Explanation:
As the acceleration is constant and time taken is also same and distance covered is halfed so the speed will also be halfed.
Answer:
The bone is compressed to 4.213*10⁻⁶ m.
Explanation:
Given that ,
Mass of the person M = 85 kg,
Length of femur L =0.65 m
Radius of femur r = 0.02 m
To find,
Compression of the bone l = ?
The Young's Modulus is given by Y=
Young's modulus of human femur bone is Y = 9.4 *10⁹ Pa
Rearranging formula ,
l =
Weight supported by femur bone is 85 *0.9 =76.5 Kg
Area = π r² =3.14* (0.02)² = 0.001256 m
The length of compressed bone is
l = = =4213.89 *10⁻⁹
l = 4.213*10⁻⁶ m
The bone is compressed to 4.213*10⁻⁶ m.

The answer to the question that is being presented above would be musical instruments. These instruments are used to create sounds of different pitches and tones by musicians. They operate through being striked or 'sawed' to create vibrations that produce sound.
