Answer:
(a) T = 0.412s
(b) f = 2.42Hz
(c) w = 15.25 rad/s
(d) k = 86.75N/m
(e) vmax = 5.03 m/s
Explanation:
Given information:
m: mass of the block = 0.373kg
A: amplitude of oscillation = 22cm = 0.22m
T: period of oscillation = 0.412s
(a) The period is the time of one complete oscillation = 0.412s
The period is 0.412s
(b) The frequency is calculated by using the following formula:

The frequency is 2.42 Hz
(c) The angular frequency is:

The angular frequency is 15.25 rad/s
(d) The spring constant is calculated by solving the following equation for k:

The spring constant is 86.75N/m
(e) The maximum speed is:

(f) The maximum force applied by the spring if for the maximum elongation, that is, the amplitude:

The maximum force that the spring exerts on the block is 17.35N
Answer:
Explanation:
Low density is an area of rarefaction.
1.) Sexual reproduction increases genetic diversity in many species of plants and animals because of meiosis. During meiosis, crossing-over occurs and changes up genes in the chromosomes. Each gamete (sperm and egg), have half the chromosomes (23) and combine to have 46 chromosomes. This is how you get traits from your parents that make you different.
2.) Asexual reproduction occurs when a single parent copies its own DNA and genes and grows an identical version or clone of itself.
The formula to use is: I = (<span> ΔV / R )
Once you solve for R, your new formula would be: R= (</span><span> ΔV / I )
Plug in your values to get: R = (1.5V / .75A )
Finally, R = 2</span><span>Ω</span>
