From the dimensional analysis of the given units, it may be deduced that in order to determine the value of the charge, we have to divide the given force by the electric field such that
                               Charge = (2.4 x 10-3N) / (6.8 x 10-5 N/C)
                                Charge = 35.29 = 3.5 x 10^1 C
Thus, the answer is letter D.

Answer:

D.3.5 × 101 C

Explanation:

The relationship between the force F experienced by a charge of magnitude q in an electric field of strength E is given by

F=qE

In this problem, we know the magnitude of the force (F=2.4 \cdot 10^{-3}N and of the electric field (E=6.8 \cdot 10^{-5}N/C), so we can re-arrange the previous equation to find the magnitude of the charge, q:

q=\frac{F}{E}=\frac{2.4 \cdot 10^{-3}N}{6.8 \cdot 10^{-5} N/C}=35.2 C=3.5 \cdot 10^1 C

Andreas93 [3]

His total displacement from his original position is -1 m

We know that total displacement of an object from a position x to a position x', d = final position - initial position.

d = x' - x

If we assume the lad's initial position in front of her house is x = 0 m. The lad then moves towards the positive x-axis, 5 m. He then ends up at x' = 5 m. He then finally goes back 6 m.

Since displacement = final position - initial position, and his displacement is d' = -6 m (since he moves in the negative x - direction or moves back) from his initial position of x' = 5 m.

His final position, x" after moving back 6 m is gotten from

x" - x' = -6 m

x" = -6 + x'

x" = -6 + 5

x" = -1 m

Thus, his total displacement from his original position is

d = final position - initial position

d = x" - x

d = -1 m - 0 m

d = -1 m

So, his total displacement from his original position is -1 m

A car drives around a curve with radius 400 m at a speed of 32 m/s. The road is banked at 7.0 degree. The mass of the car is 150
Ronch [10]

Answer:

The magnitude of the centripetal force to make the turn is 3,840 N.

Explanation:

Given;

radius of the cured road, r = 400 m

speed of the car, v = 32 m/s

mass of the car, m = 1500 kg

The magnitude of the centripetal force to make the turn is given as;

F_c = \frac{mv^2}{r}

where;

Fc is the centripetal force

F_c = \frac{mv^2}{r} \\\\F_c = \frac{(1500)(32)^2}{400}\\\\F_c = 3,840 \ N

Therefore, the magnitude of the centripetal force to make the turn is 3,840 N.
