vekshin1

Explanation:

u = 13m/s

s = 36.2m

a = 9.81m/s² (positive because it is acting on the same direction as the velocity)

Using Kinematics, we have v² = u² + 2as = (13)² + 2(9.81)(36.2) = 879.244m²/s². => v = 29.65m/s.

How did the old view of the solar system look like
zhuklara [117]
The old view of the solar system was geocentric, which means that people believed that the Earth is the center of the universe. However, with the discoveries of Galileo, Newton, and Copernicus, evidence was brought forth that the solar system is actually heliocentric, which means that the sun is the center of the universe.

A wire runs left to right and carries a current in the direction shown. What is the direction of the magnetic field at point Z?
Vanyuwa [196]
The correct option is out of the screen.

As the motion of positive charge is the direction of current in the wire. From the right-hand curl rule, the magnetic field direction will be outside the paper or the screen. As the <span>wire runs left to right and carries a current in the direction from left to right, the magnetic field lines will be outside the screen.</span>

Nezavi [6.7K]

Answer:

roof bow upwards

Explanation:

The top of the roof of the small ranger vehicle will bow upwards. This is as a result of gas pressure on the soft ragtop roof.

  • As air begins to fill the vehicle, pressure resonates in all direction proportionally.
  • The pressure of the air will be greater than that which the roof can withstand and this forces the roof sky up.
  • It is a common scene when we see roof of ragtop vehicles bowing upwards into the sky.
