By elasticity, the most nearly load is D. 12370 N .
We need to know about elasticity to solve this problem. In elasticity, stress can be determined as
σ = e . δ
where σ is stress, e is elastic modulus and δ is the strain
From the question above, we know that:
e = 70 GPa = 70 x 10⁹ Pa
d = 15 mm = 0.015 m
δ = 0.001 mm/mm
Find the stress
σ = e . δ
σ = 70 x 10⁹ . 0.001
σ = 7 x 10⁷ Pa
Find the surface area of the aluminum rod
A = πR²
A = π(0.015/2)²
A = 1.77 x 10¯⁴ m²
Find the load
F / A = σ
F = σ x A
F = 7 x 10⁷ x 1.77 x 10¯⁴
F = 12375 N

Answer:
C) to produce white blood cells
Explanation:
Your liver does all of the others things except produce white blood cells
If it helps consider making brianliest (it helps alot)
Answer:
True
Explanation:
If we swing a bucket of water fast enough in a vertical circle the water does not spill out even at the top-most position of the bucket. This happens because the centrifugal force acting away from the center in a circular motion neutralizes or overcomes the gravitational force on the water particles.
<u>Centrifugal force is mathematically related as:</u>
where:
m = mass of the revolving body
r = radius of revolution
angular velocity in radians per second
This force F acts in radially outward direction.
Given that,
Radius of track, r = 50 m
time , t = 9 s
velocity, v = ?
Distance covered by car in one lap around a track is equal to the circumference of the track.
C = 2 π r = 2 * 3.14 * 50
C = 314.159 m
Distance covered by car, s = 314.159 m
Velocity = distance/ time
V = 314.159 / 9
V = 34.9 m/s
The average velocity of car is 34.9 m/s.
Pressure = height x density x gravity = 10 x 1000 x 10 = 100 000 Pascals
