Assume that the wavelengths of photosyntheticallyactive radiations (PAR) are uniformly distributed at integernanometers in the r

ed spectrum from 675 to 700 nm.a. What are the mean and variance of the wavelength distributionfor this radiation?b. If the wavelengths are uniformly distributed at integernanometers from 75 to 100 nanometers, how do the meanand variance of the wavelength distribution compare to theprevious part? Explain.

A jet travels at 489 meters per second how long does it take to travel 235 m? answer in seconds
Sladkaya [172]

if in 1 second the jet goes 428 meters and you want to know how long it takes to go 237 meters you just divide 237/428  

it can be written like this  

_1_ = __x__  

428 237  

cross multiply  

428 times x = 1 times 237  

428x=237  

divide by 428 on both sides  

x= 237/428  

x=0.5537 seconds

dem82 [27]

Answer:2m/s^2

Explanation:

mass=5kg

Force=10N

Acceleration=force ➗ mass

Acceleration=10 ➗ 5

Acceleration=2m/s^2

A net force of Fnet acts on an object, causing the object to accelerate at a rat of 9m/s/s. what is the acceleration rate in a s
Readme [11.4K]

The new acceleration is c) 18m/s/s

Explanation:

Net force, mass and acceleration of an object are related by Newton's second law of motion:

F=ma

where

F is the net force on the object

m is its mass

a is its acceleration

In the first trial of this problem, a net force of F_{net} is applied to the object, causing an acceleration of

a=9 m/s^2

Calling the mass of the object 'm', this means that

F_{net} = ma = 9m [N] (1)

In the second trial, the force applied is 2F_{net}, so we have

2F_{net} = ma'

where a' is the new acceleration. Substituting (1) into the second equation, we find:

2(9m) = ma' \rightarrow a' = 18 m/s^2

This is because the acceleration is directly proportional to the force applied: therefore, if the force applied doubled, the acceleration doubles as well.
