Answer:

300.16m/s

Explanation:

An artillery shell is fired at an angle to the horizontal. Its initial velocity has a vertical component of 150 meters per second and a horizontal component of 260 meters per second. What is the magnitude of the initial velocity of the shell?

note velocity is the change in displacement to time

to find the magnitude of the initial speed ,

we will find the square of the vertical component plus the square of the horizontal component. then we look for the square root

U=\sqrt{Ux^2+Uy^2}

U=\sqrt{260^2+150^2}

U=90,100^2

U=300.16m/s

means that it covers 300.16m in 1 seconds

________ 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.
