Answer and Explanation:
A. We have temperature t = 32
Speed of sound, s = 1087.5
As t increases by 1⁰f speed increases by 1.2
So that
S = 1088.6
T= 33⁰f
We have 2 equations
1087.5 = k(32) + c
1088.6 = k(33) + c
Subtracting both equations
(33-32)k = 1088.6-1087.5
K = 1.1
b.). S = kT + c
1087.5 = 32(1.1) + c
Such that
C = 1052.3
Therefore
S = 1.1(t) + 1052.3
C.). S = 1.1t + 1052.3
We make t subject of the formula
T = s/1.1 - 1052.3/1.1
T = 0.90(s) - 956.3
D. This means that We have temperature to rise by 0.90 whenever speed is increased
Answer:
On a velocity-time graph… slope is acceleration. the "y" intercept is the initial velocity. when two curves coincide, the two objects have the same velocity at that time.
To solve this problem it is necessary to use the given proportions of power and energy, as well as the energy conversion factor in Jules to Calories.
The power is defined as the amount of energy lost per second and whose unit is Watt. Therefore the energy loss rate given in seconds was
The rate of energy loss per day would then be,
That is to say that Energy in Jules per lost day is 5356800J
By definition we know that 
In this way the energy in Cal is,
The number of kilocalories (food calories) must be 1279.694 KCal
Answer:
a
b
Explanation:
From the question we are told that
The charge on each water drop is 
The distance of separation is 
Generally the electrostatic force between the water drops is mathematically represented as
Here k is the coulombs constant with value 
So
Generally the quantity of charge is mathematically represented as
Here n is the number of electron present
and e is the charge on one electron with value 
So
An example for ruining a biodiversity is fishing.
The two factors that have
contributed to increased fishing in deep ocean waters in recent years are the
human population growth and decreased fishing opportunities inshore. Increase
population growth increases the demand for food which also leads to increase in
fish demand. Because the fish demand is high, inshore fishing opportunities
decrease that is why deep ocean waters is the new venue for fishing. This may sound absurd but poaching for subsistence is likely to be less damaging to he biodiversity <span>of an area than poaching for profit. Because the people do not care anymore to the biodiversity that they interrupted just to get back more profit. They do not care what must be taken from it like getting bigger fishes and leaving the smaller ones behind to maintain productivity.</span>
