Answer:
A
Explanation:
The others are only when the poles are the same as in south pole and south pole however north pole and south pole do connect cause they are oppisites
The solubility properties of the components.
Salt is soluble in water so the mixture may be placed in water and then filtered. The saw dust will be retained on the filter paper.
Answer:
a. Decreases
b. Increases
c. Remains the same
d. Increases
Explanation:
a. Capacitance is given by c= Ak€/d
where A is conductivity plate with Area
K is a constant
€ is dielectric with permittivity.
d is the distance
b. Potential difference is given by
V = Ed, since, the electric field remains the
same, the potential diterence also increases with increase in distance.
Since the capacitance depends upon the distance, and all the other factors are kept constant, the capacitance decreases.
c. Electric field remains the same because charge on the
plate remains the same.
d. since electric field remains the same and capacitance decreases, the energy increases.
E= 1/2c * Q^2
Answer:
Distance 20 km and Displacement 0 km
His displaceent is 0 km because he ends his walk where he started. The total distance of his walk is 20 km because he walks 10 km to the store + 10km back home.
Answer: -0.068
Explanation:
A familiar correlation number of R² denotes the degree of correlation between measured data and the curve of best fir
R² = 1 denotes a perfect fit, so that
R = +1, or R = -1 denotes a perfect fit.
R² = 0 denotes no correlation.
To compare the given correlation numbers, we should consider their absolute values. In decreasing order, they are
-0068 => 0.68
0.46 => 0.46
-0.041 => 0.41
0.32 => 0.32
