Explanation:
The text explains how Mendall's studies showed that the purple flower was dominant to the white flower this is shown by how all of the first generation flowers were all purple instead of white.
Answer:
a) P=974,028.25 Pascals
b) P=159,154,943.1 Pascals
Explanation:
<u>Pressure</u>
It's measured as the ratio of the force F applied perpendicular to a surface of area A. Its units are Pascal, PSI, atmospheres, bars, mm Hg, among many others.
a)
Our man has a weight of 765 Nw. When he lies on the bed of nails, his weigh will be (uniformly) distributed among them all. It there are 1000 nails, each one will take a force of
The flattened point on each nail has a radius of 0.500 mm = 0.0005 meters, we can compute its area as a circle
The pressure of each nail will be
Or equivalently
b)
We can similarly calculate the pressure exerted on the skin by an acupuncture needle of radius 0.100 mm (0.0001 m) applied with a force of 5 N
Or equivalently
Answer:
there are 3 significant figures.
Explanation:
significant figures are 3,4,7.
a) Magnitude of force is 5.37N
b) Angle of force is - 37.88°
<h3>What is force?</h3>
In physics, we define a force is an influence that can change the motion of object. A force can cause an object with mass to change to accelerate.
Given force from above is 5.9N
∑Fₓ = F₁ₓ + F₂ₓ+F₃ₓ = 0
F₂ cos 44° + Fₓ = 0
Fₓ = - 5.9 cos44°
= - 4.24 N
Given force that acts downward as 7.4N
∑Fy= Fy1+ Fy2 +Fy3 =0
Fy+ 5.9 sin 44° - 7.4= 0
F = 3.30 N
F =√Fₓ² +Fy²
= 5.37 N
b) angle of force= tan⁻¹ (3.30/-4.24)
= - 37.88°
