Which of the following rules should be used to keep the appropriate distance between your vehicle and the vehicle in front of you?

Answers

Answer 1
Answer: The correct answer is C) Two-second rule.

This means that a driver must maintain a distance that would take at least 2 seconds to cover, at the current speed of the car. This means that in case the car in front suddenly comes to a full stop, the driver of the car behind has 2 seconds react and hit his own brakes. A two-car length rule might be alright when driving at low speeds, but when going at high speeds (on a highway, for example), a two-car length can be covered in a fraction of a second, which means a sudden braking by the car in front would almost guarantee an accident.
Answer 2
Answer:

Answer:

4-second following distance

Why do the track runners start at different positions on the track?

Answers

Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.

In track events, particularly in sprints, the distance to be covered is the same for all competitors (e.g., 100 meters, 200 meters, 400 meters, etc.).

To compensate for the curved shape of the track, which can create unequal distances for runners in outer lanes compared to those in inner lanes, runners start from staggered positions. The lanes closer to the inner part of the track have a smaller radius and, therefore, a shorter distance to cover in each lap compared to the outer lanes.

By starting at staggered positions, each runner has an equal distance to run during the race. This helps ensure fairness in the competition and eliminates the advantage that could be gained by running in a specific lane.

The starting positions are determined based on the lane number, with the innermost lane (lane 1) starting at the shortest distance from the finish line and the outermost lane starting at a greaterdistance to compensate for the curvature of the track. This ensures that all runners have an equal opportunity to perform at their best regardless of the lane they are assigned to.

Hence, Track runners start at different positions on the track to ensure that each runner covers the same distance during the race.

What is the bond between Hydrogen and Chlorine?

Answers

polar covalent bond
Hydrogen chloride is a diatomic molecule, consisting of a hydrogen atom H and a chlorine atom Cl connected by a polar covalent bond. The chlorine atom is much more electronegative than the hydrogen atom, which makes this bond polar.
covalent bond
