To prevent further injury
Nothing if it strikes lava and if lava is able to withstand a nuke but if it strikes somewhere else it could result in a nuclear war
The line that indicates areas where the pressure is the same on a weather map is called isobar.
The term isobars refer to the lines that connect the points with same atmospheric pressure on a weather map. The distribution of the isobars is affected by many factors, such as the magnitude and the direction of the wind.
Answer:
Approximately 3.03 seconds.
Explanation:
The distance traveled in the vertical direction is given by the kinematic equation:
Where <em>v</em>_<em>iy</em> and <em>a</em> are the initial velocity and acceleration of the object, respectively, in the vertical direction.
Because the rock is thrown horizontally, there is no horizontal velocity. Therefore:
The vertical acceleration is simply gravity <em>g. </em>This, this yields the general equation:
Substitute 45 m for <em>y</em> and solve for time <em>t:
</em>
Therefore, it will take approximately 3.03 seconds for the rock to fall 45 meters vertically.
