If you walk a distance of 8 blocks and then 3 blocks south from home, what is your position compared to home? What distance did
Harman [31]

The position compared to that of home is a reference to displacement, I believe.

Displacement = x total - x initial

So I believe the answer is 5 blocks due north (if you’re walking linearly from your home), unless the questions is referring to relative displacement, in which then you’d need to use the Pythagorean theorem to find the hypotenuse between both positions. And then you’d have to find theta for the degrees between the south direction and the other unmentioned direction. But I don’t think that’s the case.

Distance refers to x total and doesn’t care for direction, as this refers to a scalar quantity opposed to a vector. Thus the equation is just

d = x

So 8 blocks + 3 blocks = a distance of eleven blocks walked total

What term described the capability to prevent one participant in an electronic transaction from denying it performed an action?
vampirchik [111]

Answer:

Plausible deniability.

Explanation:

Plausible deniability.

It is the ability of a person to refuse to accept knowledge of responsibility, if any secret(demeaning) action is done by others in an organizational hierarchy as there may be lack of evidence to confirm their involvement. Specially for high level official who can willfully deny any awareness of the to avoid themselves getting involved in blame game.

On an amusement park ride, passengers are seated in a horizontal circle of radius 7.5 m. The seats begin from rest and are unifo
timofeeve [1]

Answer:

a = 0.5 m/s²

Explanation:

Applying the definition of angular acceleration, as the rate of change of the angular acceleration, and as the seats begin from rest, we can get the value of the angular acceleration, as follows:

ωf = ω₀ + α*t

⇒ ωf = α*t ⇒ α = \frac{wf}{t} = \frac{1.4 rad/s}{21 s} = 0.067 rad/s2

The angular velocity, and the linear speed, are related by the following expression:

v = ω*r

Applying the definition of linear acceleration (tangential acceleration in this case) and angular acceleration, we can find a similar relationship between the tangential and angular acceleration, as follows:

a = α*r⇒ a = 0.067 rad/sec²*7.5 m = 0.5 m/s²

a traffic light at an intersection is hanging from two wires of equal length making angles of 10 degrees below the horitzontal.
aleksandrvk [35]

The tensions in the wires at the given angle of inclination is determined as 434.1 N.

<h3>Tension on the wire</h3>

The tension in the wires is calculated as follows;

T = Wsinθ

where;

  • T is tension in each wire
  • W is weight of the traffic light

T = 2500 x sin(10)

T = 434.1 N

Thus, the tensions in the wires at the given angle of inclination is determined as 434.1 N.
