Answer:

The answer is B.

Explanation:

The allelic combination of the living being is known as its genotype. The genotype is answerable for deciding the qualities (phenotype) of the creature. Be that as it may, these attributes are not exclusively controlled by the genotype but instead the association between the genotype and nature where the creature exists.

Hope this helps & good luck! (:

Use differentials to estimate the amount of tin in a closed tin can with diameter 3 inch and height 4 inch, if the top and botto
Aloiza [94]

Answer:

dv = 1.03 inch^3

Explanation:

given data:

diameter = 3 inch

radius = 1.5 inch

height 4 inch

top and bottom thickness is 0.02 inch

side thickness = 0.015 inch

we know that volume of the cylinder is given as

v  =\pi r^2 h

by definition of differential we have

dv =\frac{\partial v}{\partial r} dr + \frac{\partial v}{\partial h} dh

where dh = -(0.02  + 0.02) = 0.04 inch    [ sum of top and bottom thickness]

the radius is decreased by 0.02 inch, dr = 0.02 inc,

\frac{\partial v}{\partial r}  = 2\pi r h = 37.69

\frac{\partial v}{\partial h} = \pi r^2 = 7.06

dv = 37.69*(0.02) + 7.06*(0.04)

dv = 1.03 inch^3

A 2.2 kg box is sliding along a frictionless horizontal surface with a speed of 1.8 m/s when it encounters a spring. (a) Determi
iogann1982 [59]

Answer:

a) k = 2851.2\,\frac{N}{m}, b) v = 0.54\,\frac{m}{s}

Explanation:

a) According to the Principle of Energy Conservation, the kinetic energy of the box is transformed into elastic potential energy.

\frac{1}{2}\cdot (2.2\,kg)\cdot (1.8\,\frac{m}{s} )^{2} = \frac{1}{2}\cdot k \cdot (0.05\,m)^{2}

The spring constant is:

k = 2851.2\,\frac{N}{m}

b) The initial speed needed to compress the spring by 1.5 centimeters is:

\frac{1}{2}\cdot (2.2\,kg)\cdot v^{2} = \frac{1}{2}\cdot (2851.2\,\frac{N}{m} )\cdot (0.015\,m)^{2}

v = 0.54\,\frac{m}{s}

This is a graph of a marble traveling across a smooth surface. What is the average speed of this marble?
prohojiy [21]
Since it is a smooth marble and basing from the graph, it has a constant slope, you could just get any two points along the line and get its slope since speed is Δd/Δt. Let the points be (4,6) and (6,9). Thus,

Δd/Δt = (9-6)/(6-4) = 1.5

Thus, the average speed is 1.5 m/s.
