the answer is ionic bonds
hope this helps
The correct answer would be D.
The resultant force of both forces is 15.62 N.
<h3 /><h3>What is resultant?</h3>
The Resultant of forces is a single force obtained when two or more forces are combined.
To calculate the resultant of the force, we use the formula below.
Formula:
- R = √[a²+b²-2abcos∅]..................... Equation 1
Where:
- R = Resultant of the forces.
- ∅ = Angle between both forces
From the question,
Given:
Substitute these values into equation 1
- R = √[8²+10²-2×8×10cos120°]
- R = √[64+100-160cos120°]
- R =√ [164-160(-0.5)]
- R = √[164+80]
- R = √(244)
- R = 15.62 N
Hence, the resultant force of both forces is 15.62 N.

Answer:
Explanation:
In the given case for destructive interference , the condition is,
path difference = (2n+1)λ /2 where n is an integer and λ is wavelength
2 μ d = (2n+1)λ /2
Putting λ = 653 nm
for minimum thickness n = 0
2 μ d = 653 / 2 nm
= 326.5 nm
For constructive interference the condition is
2 μ d = n λ₁
326.5 nm = n λ₁
λ₁ = 326.5 / n
For n = 1
λ₁ = 326.5 nm ,
or , 326.5nm .
Longest wavelength possible is 326.5
Hey there!
In this case, it is possible to solve this problem by using the widely-known steam tables which show that at 90 °C, the pressure that produces a vapor-liquid mixture at equilibrium is about 70.183 kPa (Cengel, Thermodynamics 5th edition).
Moreover, for the calculation of the volume, it is necessary to calculate the volume of the vapor-liquid mixture, given the quality (x) it has:
Thus, since 8 kg correspond to liquid water, 2 kg must correspond to steam, so that the quality turns out:
Now, at this temperature and pressure, the volume of a saturated vapor is 2.3593 m³/kg whereas that of the saturated liquid is 0.001036 m³/kg and therefore, the volume of the mixture is:
This means that the volume of the container will be:
