The fraction of the tensile strength which is the stress on the femur is 1.4%.
<h3>What is Tensile strength?</h3>
This is defined as the amount of load or stress that a material can handle before it stretches and breaks.
The femur which is located in the thigh is the largest bone in the body and it exerts a fraction of 1.4% tensile strength through the stress encountered on the femur when the man stands with one leg.

The answer is D- it has a high resistance and is a conductor
hope this helps !
Answer:
<em>The correct option is 1. 720 m</em>
Explanation:
<u>Projectile Motion</u>
When an object is launched in free air (no friction) with an initial speed vo at an angle 
, it describes a curve which has two components: one in the horizontal direction and the other in the vertical direction. The data provided gives us the initial conditions of the survival package's launch.
The initial velocity has these components in the x and y coordinates respectively:
And we know the plane has an altitude of 600 m, so the package will reach ground level when:
The vertical distance traveled is given by:
We'll set up an equation to find the time when the package lands
Solving for t, we find only one positive solution:
The horizontal distance is:
The correct option is 1. 720 m
The answer is c, because ball is falling so its gravitationl potential energy decreases, but it kinetic energy increases. Energy is always conserved.
Answer:
Explanation:
Initial kinetic energy = 29 J
work done against gravity = mgsin33 x d , m is mass of the block
= 1.2 x 9.8 sin 33 x .9
= 5.76 J
potential energy stored in compressed spring
= 1/2 k x², k is spring constant and x is compression
= .5 x 200 x .3²
= 9
energy left = 29 - ( 5.76 + 9 )
= 14.24 J
b )
energy stored in spring when compression is .4 m
= 1/2 x 200 x .4²
= 16 J
required kinetic energy = 16 + 5.76
= 21.76 J
Block must be projected with energy of 21.76 J .
