Answer:
1681714.28571 N/C
Yes it could exist
Explanation:
m = Mass of housefly = 12 m
q = Charge = 70 pC
g = Acceleration due to gravity = 9.81 m/s²
E = Electric field
When an object accumulates charge it means that it is gaining electrons making it negatively charged. This is the concept of static electricity.
Here, the electric force and the graviational force will balance each other
1681714.28571 N/C of electric field would be required to levitate
The direction of the electric field would be upwards vertically.
In air the critical value of electric field is which is more than the critical value of electric field in air. So, the electric field can exist.
Answer:
The equation of displacement is .
Explanation:
Given that,
Distance = 2.50 m
We need to calculate the equation of wave
Using general equation of wave
....(I)
Where, A = amplitude
t = time
x = displacement
= phase difference
Put the value in the equation
At t = 0, x = 0, y =A
From equation (I)
Hence, The equation of displacement is .
I think its supposed to be something like this
Use the terminal velocity formula, v = the square root of ((2*m*g)/(ρ*A*C)).<span>m = mass of the falling object.
</span><span>g = the acceleration due to gravity.
</span><span>p = the density of the fluid the object is falling through.
</span><span>a = the projected area of the object.
</span><span><span>c = the drag coefficient.</span></span>
My grandfather is a whiz at math so helped me figure it out
The question is incomplete, the complete question is;
A scientist would most likely need to update her model when it
a.has become too simple.
b.no longer supports the latest results.
c.reduces the need for verbal explanation of data.
d.no longer appears interesting.
Answer:
b.no longer supports the latest results.
Explanation:
In science, models are prepared to explain experimental results. Each model must have a solid framework supported by experimental results.
However, science is never static. Given the dynamic nature of science, it is possible that latest experimental evidence may no longer support the existing model and the model will need to be reviewed in the light of emerging experimental results.
