It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.
Below are the questions:
A) A hovering mosquito is hit by a raindrop that is 45 times as massive and falling at 8.9m/s , a typical raindrop speed. How fast is the raindrop, with the attached mosquito, falling immediately afterward if the collision is perfectly inelastic?
<span>B) Because a raindrop is "soft" and deformable, the collision duration is a relatively long 8.0 ms. What is the mosquito's average acceleration, in g's, during the collision? The peak acceleration is roughly twice the value you found, but the mosquito's rigid exoskeleton allows it to survive accelerations of this magnitude. In contrast, humans cannot survive an acceleration of more than about 10 g.

Below are the answers:
a. <span>MU = (M + m)V; where M = 45 m, U = 8.9 m/s, find V = ?. V = (45/46)*8.9 = 8.7 m/s
</span>
b. <span>F = m dV/dT = m 8.7/8E-3 = m 1.0875E+03; so G = 1.0875E+03/9.8 = 111 G's.</span>
Answer:
The child is suffering from measles which is caused by the measles virus. It is also known as rubeola.
Explanation:
The infection is measles because the child is suffering from sore throat, headache, high fever and a cough. White spots with red margin also develop on the mucous membrane of the mouth after a couple of days. These symptoms are seen in measles infections.
The white spots which develop inside the mouth are known as koplik’s spots.
The measles is an airborne disease and spreads through the cough and sneezes of a person who is infected with it. Measles is very contagious . The measles virus spreads in the body for 10-14 days after infection, then mild fever, cough and runny nose lasts for 2-3 days. In the next few days , the rash spreads over the body and there is high fever.

Im guessing positive and negative energy
Answer:
False.
Explanation:
The cell membrane potential or the membrane potential is the difference in potential voltage inside and outside of the cell. Two main types of synaptic potential are inhibitory postsynaptic potentials and excitatory postsynaptic potentials.
IPSPs makes the cell membrane potential more negative and hyperpolarizes the cell. EPSPs makes the cell membrane potential more positive and causes the cell depolarization.
Thus, the answer is false.
