The significant figures also known as the significant digits or precision of a number written in positional notation are digits that carry meaningful contributions to its measurements
Letters A and D appear to be correct.
The correct answer is <span>make sure everyone on board is wearing a life jacket. This is done as a safety precaution in case things go bad because there should always be enough lifej ackets for all people aboard. They can remove them later. The procedure is similar to how flights have you wear the seatbelt in the beginning and the end.</span>
Answer:
Lets take mass of A = m
Mass of B = m
Lets take spring constant = K
Displacement of mass A = x
Displacement of mass B= x'
Given that
x ' > x
a)
We know that time period of spring mass system given as
Time does not depends on the displacement.
So time will be same for both.
b)
We know that acceleration given as
a= ω² .x
ω=natural frequency ( ω² = m K)
Here x ' > x
So Acceleration of mass B is greater than mass A.
c)
Velocity at equilibrium position
V= ω .x
Here x ' > x
So velocity of mass B is greater than mass A.
d)
As we know that at equilibrium point acceleration of the mass is zero.So both the mass have same acceleration and the value of this acceleration will be zero m/s².
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>
