The toxic effects of water pollution are generally very harmful for all living animals and plants. Numerous water borne diseases can effect animals and humans in the same way and can even lead to death. The toxic effects of water can make the temperature of the water rise. Also it can effect the conductivity and acidity of water.
Answer:
x = 1.00486 m
Explanation:
The complete question is:
" The potential energy between two atoms in a particular molecule has the form U(x) =(2.6)/x^8 −(5.1)/x^4 where the units of x are length and the num- bers 2.6 and 5.1 have appropriate units so that U(x) has units of energy. What is the equilibrium separation of the atoms (that is the distance at which the force between the atoms is zero)? "
Solution:
- The correlation between force F and energy U is given as:
F = - dU / dx
F = - d[(2.6)/x^8 −(5.1)/x^4] / dx
F = 20.8 / x^9 - 20.4 / x^5
- The equilibrium separation distance between atoms is given when Force F is zero:
0 = 20.8 / x^9 - 20.4 / x^5
0 = 20.8 - 20.4*x^4
x^4 = 20.8/20.4
x = ( 20.8/20.4 )^0.25
x = 1.00486 m
Nebular cloud should be the answer, but i believe nuclear fusion is the closest answer, because it fuses together to become a cloud
hope this helps
Answer:
We can use this expression to find the maximum velocity or velocity just before touching the ground. For this problem, v = √2×10×500 = 100m/s.
Answer: Option C) 11.25 A
Explanation:
Given that:
Voltage V = 90 volts
total current I = ?
Three resistors each with 40 Ω, 30 Ω, and 15 Ω in parallel, the equivalent resistance of the combination (Rtotal) of the circuit is as follows:
i.e 1/Rtotal = (1/R1 + 1/R2 + 1/R3)
1/Rtotal = (1/40Ω + 1/30Ω + 1/15Ω)
1/Rtotal = (3 + 4 + 8)/120Ω
1/Rtotal = 15/120Ω
1/Rtotal = 1/8Ω
To get the value of Rtotal, cross multiply
Rtotal x 1 = 8Ω x 1
Rtotal = 8Ω
Then, apply the formula V = I x Rtotal
90 volts = I x 8Ω
I = 90 volts / 8Ω
I = 11.25 Amperes
Thus, the total current used by the three lamps is 11.25 Amperes
