0.38296 m
1.02132 rad
Explanation:
Angular frequency is given by
Displacement is given by
Velocity is given by
The phase angle is 1.02132 rad
The amplitude is 0.38296 m
The equation is given by
The equation is
It looks like the diagram is telling you that there is a net force of 8 N + 4 N = 12 N pointed to the right. By Newton's second law, the magnitude of the net force <em>F</em> is equal to the mass <em>m</em> times the acceleration <em>a</em> :
<em>F</em> = <em>m</em> <em>a</em>
12 N = (4 kg) <em>a</em>
<em>a</em> = (12 N) / (4 kg)
<em>a</em> = 3 m/s²
Answer:
Which of the following best describes a property of water?
A. Having a narrow temperature range for a liquid state
B. Requiring a low amount of heat to change temperature
C. Having high surface tension
D. Being unable to dissolve many substances
Explanation:
c
Sulphur
The missing element is sulphur
Here the compound is composed of element X and chlorine.
it is given,
XCl (6) ----> 6Cl
mass = 13.1%
it is X and Cl = 100%-13.10%
= 86.90%
chlorine = 86.90
X = 13.10
We assume 100g of sample
so according to the above solved data, in 100g of sample we have 86.90 g of chlorine.
now we split that chlorine into two moles of chlorine.
- Every mole of sale has 35.45 grams of sales. 2.451 moles of seal are mine after that.
- We are aware that cl is six times more than X. To find the moles of X, I must divide this number by six.
- we discover that we have 0.4086 moles of X when we divide this by six.
- We obtain those moles of X from 13.10 g of X.
- Given that Mueller masses grams per mole, I can compute the molar mass.
- 13.10 grams of X are contained in 0.4086 moles of X.
- Or, to put it another way, each remote has a molar mass of 32–06 grams.
- The element with this molar mass is sulfur, as I can see from the periodic table.
- Okay, so the element we're looking for in this situation is sulfur.
