|Acceleration| = (change in speed) / (time for the change).
Change in speed = (6 mi/hr - 25 mi/hr) = -19 mi/hr
Time for the change = 10 sec
|Acceleration| = (-19 mi/hr) / (10 sec) = -1.9 mile per hour per second
Admittedly, that's a rather weird unit.
Other units, perhaps more comfortable ones, are:
-6,840 mi/hr²
-2.79 feet/sec²
Answer: The force is directed upward
Explanation: Considering the Lorentz force, given by:
F= qv×B
using the right hand rule and considering the direction of electron velocity and the magnetic field from the figure, the vectorial product gives a force vector upwards .
A Many people who came to the hospital had very serious injuries.
Explanation:
From the passage, we can infer that many people who came to the hospital had very serious injuries.
Let us analyze the given options:
Many doctors were worried about the safety of their own families.
No where in the passage was the families of the Doctors mentioned. The passage directly spoke to the Doctors and their victims.
Many people were able to quickly leave the hospital after treatment.
There was shortage of blood and there was no way they could have been treated without it. The passage suggests an emergency situation was up.
Also, many people needed blood for treatment but there was an acute shortage. No way to treat and discharge them.
Many doctors who worked through the night wanted to go home.
Again, no text in the passage suggests this. We have a picture of Doctors who wanted to tend to their patients but lacked the means to do so.
<em>The fitting inference that can be drawn from the passage is that many people came to the hospital had serious injuries which led to blood shortage. </em>
