Question:
What quantity do units represent in a value? A. Size B. Direction C. Magnitude D. Dimension
Answer:
D. Dimension
Explanation:
A unit is simply the measurement given to a dimension. In other words, units represent dimensions. For example, consider a ruler that is 20m long.
i. The value is 20m.
ii. The magnitude of the measurement is 20
iii. The unit of the measurement is meters(m) and that essentially represents the dimension (length) of the ruler.
To solve the problem it is necessary to apply the concepts related to Kepler's third law as well as the calculation of distances in orbits with eccentricities.
Kepler's third law tells us that
Where
T= Period
G= Gravitational constant
M = Mass of the sun
a= The semimajor axis of the comet's orbit
The period in years would be given by
PART A) Replacing the values to find a, we have
Therefore the semimajor axis is
PART B) If the semi-major axis a and the eccentricity e of an orbit are known, then the periapsis and apoapsis distances can be calculated by
I think your answer is D
because you already said its not a B is a liquid and not a solid so its harder to have a chemical change C is solutions and D is compound and I know for a fact that a compound is a solid and if C is also a solid then that could also be a possible answer choice.
Answer:
A chlorinated swimming pool would be a homogenous mixture because chlorine and water diffuse through each other and cannot be separated out as distinct materials. It is impossible to separate the chlorine from water as they homogenously mix and cannot be separated into their pure forms.
Explanation:
Answer:
a) γt = 120.107 lbf/ft³
b) γt = 121.455 lbf/ft³
c) γt = 122.803 lbf/ft³
d) γt = 124.150 lbf/ft³
Explanation:
Given:
e = 0.76
Gs = 2.74
γw = 62.43 lbf/ft³
a) S = 85%
b) S = 90%
c) S = 95%
d) S = 100%
We can apply the formula
γt = γw*(Gs+S*e)/(1+e)
a) γt = (62.43 lbf/ft³)*(2.74+0.85*0.76)/(1+0.76)
γt = 120.107 lbf/ft³
b) γt = (62.43 lbf/ft³)*(2.74+0.90*0.76)/(1+0.76)
γt = 121.455 lbf/ft³
c) γt = (62.43 lbf/ft³)*(2.74+0.95*0.76)/(1+0.76)
γt = 122.803 lbf/ft³
d) γt = (62.43 lbf/ft³)*(2.74+1*0.76)/(1+0.76)
γt = 124.150 lbf/ft³
