________ occurs when a person is holding an object that is directly hit or splashed by lightning.
Papessa [141]

When someone is holding something that has been struck or splashed by lightning, contact damage occurs.

We need additional information concerning lightning and injuries in order to identify the solution.

<h3>What types of injuries are brought on by lightning?</h3>
  • Lightning is the name for a natural electrical discharge that occurs quickly and with a dazzling flash.
  • It has a tremendous amount of energy.
  • Lightning-related injuries can be divided into three categories: direct strikes, side splashes, and contact injuries.
  • When someone is struck by lightning directly, they can get direct injury.
  • When a current splashes from a neighboring object, it is called a side splash.
  • When someone touches a lightning-hit object, contact harm results.

In light of this, we can say that contact injuries happen when a person is holding an object that has been struck by lightning or splashed by it.

_______________ will occur if a vehicle collides with an object travelling in the opposite direction rather than colliding with
dsp73

More impact will occur if a vehicle collides with an object traveling in the opposite direction rather than colliding with a stationary object.

<h3>What is Collision?</h3>

A collision may be described as a circumstance in which two or more bodies exert forces on each other in a moderately short period of time.

When vehicles collide with an object traveling in the opposite direction causes more impact because both bodies exert equal forces on to each other. While a stationary object bears less force, and hence the collision causes a little or less impact on the bodies.

Therefore, More impact will occur if a vehicle collides with an object traveling in the opposite direction rather than colliding with a stationary object.
