Answer:

a) E = 1.47 × 10^5 N/C

b) south

Explanation:

The magnitude of an electric field can be defined mathematically as;

E = F/q ........1

Where,

E = magnitude of the electric field

F = electric force

q = charge on the proton

Given;

F = 2.36 × 10^-14 N

Note that charge on a proton is known as Qp = 1.602 × 10^-19 C

q = 1.602 × 10^-19 C

Substituting into equation 1, we have;

E = 2.36 × 10^-14 N/1.602 × 10^-19 C

E = 1.47 × 10^5 N/C

b) The direction of the electric field;

From equation 1

E = F/q ........1

since both electric field and electric force are vector quantity and q is a positive charge (constant), then both the electric field and electric force would be parallel to each other. Therefore the electric field is directed to the south also.

(When a vector is multiplied by a positive constant the direction remains the same)

Ahhh this going to be confusing sorry...
1. α = Δω / Δt = 28 rad/s / 19s = 1.47 rad/s²

2. Θ = ½αt² = ½ * 1.47rad/s² * (19s)² = 266 rads

3. I = ½mr² = ½ * 8.7kg * (0.33m)² = 0.47 kg·m²

4. ΔEk = ½Iω² = ½ * 0.47kg·m² * (28rad/s)² = 186 J

5. a = α r = 1.47rad/s² * 0.33m = 0.49 m/s²

6. a = ω² r = (14rad/s)² * 0.33m = 65 m/s²

7. v = ω r = 28rad/s * ½(0.33m) = 4.62 m/s

8. s = Θ r = 266 rads * 0.33m = 88 m

A description of both speed and direction
julia-pushkina [17]
Speed most often describes acceleration or a high rate of motion. ... As a verb, it means to “move along quickly,” like how you speed around on your bike. Direction is defined as the path that something takes, the path that must be taken to reach a specific place, the way in which something is starting to develop or the way you are facing
