If the car moves along the distance it will be 16 of the line graph where is independent of the graph
Answer: 11%
Explanation:
Given that
X = ab^2/C. Calculate percentage error in X, when percentage error in a,b,c are 4,2 and 3 respectively.
Percentage error of b = 2%
Percentage error of b^2 = 2 × 2 = 4
When you are calculating for percentage error that involves multiplication and division, you will always add up the percentage error values.
Percentage error of X will be;
Percentage error of a + percentage error of b^2 + percentage error of c
Substitute for all these values
4 + 4 + 3 = 11%
Therefore, percentage error of X is 11%
To solve this problem we will apply the concept of voltage given by Coulomb's laws. From there we will define the charges and the distance, and we will obtain the total value of the potential difference in the system.
The length of diagonal is given as

The distance of the center of the square from each of the corners is

The potential electric at the center due to each cornet charge is




The total electric potential at the center of the given square is


Al the charges are equal, and the distance are equal to a, then


Therefore the correct option is E.
Answer:
135°.
Explanation:
R = 75 ohm, L = 0.01 H, C = 4 micro F = 4 x 10^-6 F
Frequency is equal to the half of resonant frequency.
Let f0 be the resonant frequency.


f0 = 796.2 Hz
f = f0 / 2 = 398.1 Hz
So, XL = 2 x 3.14 x f x L = 2 x 3.14 x 398.1 x 0.01 = 25 ohm

Xc = 100 ohm

tan Ф = (25 - 100) / 75 = - 1
Ф = 135°
Thus, the phase difference is 135°.
Answer:

Explanation:
<u>Displacement Vector</u>
The displacement, as every vector, has a magnitude r and a direction angle θ measured from the positive x-axis.
If we know the x-y components of the displacement, the magnitude and angle can be calculated by the equations:


The coordinates of the given vector are x=-12 m, y=21 m, thus:


Since the vector lies in the second quadrant, we add 180° to find the correct direction:
