Answer:
Slope=
Explanation:
We are supposed to find the slope in a position time graph,
For that we need atleast two points .( represents there coordinates in respective axis directions.)
In the given case the y axis would be the position and the x axis as time .
Slope is defined as the ratio of change in y coordinate to change in x coordinate :-
So subsituting the coordinates of position and time we get slope as:-
[When we have more than two points which are not collinear then to calculate the slope we take the average.]
Answer:
1) move away from the windows.
When abrupt changes in pressure (produced by the hurricane) affect the windows, they can "explode" and be a serious danger for the people.
2) Go to the lowest level of the building.
Is safer than the upper levels because the lower levels suffer less from the strength of the hurricane (being closer to the ground increases the structural resistance), make sure that you have everything you may need in case of an emergency.
<span>If a behavior tends to increase after a consequence occurs, that consequence is most likely used as a catalyst. In terms of chemical reactions, catalysts are used to increase the rate of reaction. Given that, when an object causes a situation to become more frequent, then it is considered as a catalyst.</span>
<span>The magnetic field produced by a current has three distinct characteristics. The field can be turned on or off, have its direction reversed, or have its strength changed.
Therefore the correct answer is D. All of the above</span>
