Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.
The answer is B:
A chipmunk takes shelter in and oak tree and is protected from predators, and in return disperses seed around the area
It is speeding up because more distance is covered every second.
Explanation:
The car can be described to be speeding up because more distance is covered every second.
From what we understand about velocity and acceleration, the car is accelerating through the ramp.
It's velocity is increasing with every second it covers.
This will invariable reduce the time between each distance covered.
Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.
This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.

The nervous and the endocrine system are tightly linked together.
The main reason for this linkage is due to the connection of the hypothalamus (nervous system) and the hypophysis (a gland in the endocrine system)
The hypophysis is the ''controller'' of all of the other endocrine glands.
The connection between the hypothalamus and the hypophysis enables the nervous system to control the hormone levels of all of the major endocrine glands in the body.
The hypothalamus releases hormones into the bloodstream that leads to the hypophysis. These hormones induce a release of hypophysis hormones that enter the bloodstream and when they reach the target gland (for example pancreas) these hormones induce the release of the hormones of that gland (in the case of the pancreas, insulin).
The hypothalamus monitors the concentration of hormones in the blood, and a high level of a certain hormone blocks the release of the hypothalamus' hormones. Therefore, a high level of insulin blocks a cascade of hormone release that starts in the hypothalamus that leads to its release in the pancreas.
