Answer:
A. 21 rad/s
B. 200.5 rpm
C. 26.46 rad/s2
D. 0.299 Hz
Explanation:
Parameters given are:
Tangential velocity,v = 1.26m/s
Diameter (outer edge) = 0.120m
Outer edge radius, ro = 0.12/2
= 0.06m
A. Calculate Angular velocity
Angular velocity, w = v/r
= v/ro
= 1.26/0.06 = 21 rad/s
In rpm,
2pi/60 rad/s = 1 rpm
1 rad/s = 60/2pi rpm
Sp, 21 rad/s = 60 * 21/2pi rpm
= 200.5 rpm
B. Calculate the inner edge radius, ri given w = 500 rpm
Converting rpm to rad/s,
= 2pi/60 * 500 rad/s
= 52.34 rad/s
ri = v/w
= 1.26/ 52.36
= 0.024m
C. Calculating centripetal acceleration, a from the outer edge, ro
a = v2/r = w2r
= (1.26)2/0.06
= 26.46 rad/s
D. Calculate the frequency, f of the outer edge angular velocity, w = 21 rad/s
f = 2pi/w
= 2pi/21
= 0.299 Hz (or per second)
Grasshopper and cricket are two organisms in the food web would MOST LIKELY be affected by a decrease in producers, or the plants, at the bottom base of the food web.
D) grasshopper and cricket
<u>Explanation:</u>
A food web comprises of many food chains. An evolved way of life just follows only one way as creatures discover food. It is an enormous number of plants and creatures things. A food web shows a wide range of ways plants and creatures are associated with one another for their prey.
Though Grasshopper and cricket are two living beings in the nourishment web that would be generally influenced by a diminishing in makers, or the plants, at the base of the nourishment web.
Like every living life form, crickets and grasshoppers assume a significant job in keeping up the equalization of the biological system. They breakdown plant material, restoring soil minerals. They are also an important source of food for other animals.
Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants. Denitrifying bacteria converts nitrates back to nitrogen gas.
Answer;
Acetylcholine.
Nicotine mimics the action of neurotrasmitter acetylcholine.
Explanation;
Many drugs interact with receptors to either activate them or prevent their activation by their normal neurotransmitters. The drug nicotine mimics the action of acetylcholine at the nicotinic acetylcholine receptors.
