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.
I think the vehicle relation to the hearer is : Past the hearer
Have you ever walk when a motor cycle run past you ? You will notice that you will hear less sound as the motor cycle goes further
Hope this helps
Okay I will thanks rlly got me thinking about life
Answer:
2.63m
Explanation:
In order to use this expression, we must calculate the values of Velocity (V0) and Velocity(Ve). The initial velocity has only a horizontal component V(0) = V(0x), the final velocity also has a horizontal component since the ball it's at a point of trajectory, V(e) = V(ef). No forces act in the horizontal direction so the momentum of the ball in this direction is conserved, hence, V(0) = V(e)
Therefore, h(e) = h(0) = 2.63m
Answer:
= 201.53 meters
Explanation:
A car started from rest and accelerated at 9.54 m/s^2 for 6.5 seconds. How much distance was covered by the car?
Use the formula d =
where d is the distance, t is the time and "a" is the acceleration.
