Answer:
B
Explanation:
A diverging lens forms a virtual image that is as the same size as the object
Answer:


Explanation:
In order to calculate the equivalent spring constant we need to use the next formula:

Replacing the data provided:


Finally, to calculate the frequency of oscillation we use this:

Replacing m and k:

It’d fall 29.4m or 96.46ft
Explanation:
Uhh since gravity is 9.8m/s then in three seconds it’d drop 29.4m or 96.46ft
That is assuming there isn’t a lot of wind resistance, but if you take that into account, then it’d probably be somewhere around 25m since the water bottle is going to be heavier than the wind resistance, and since we don’t know the weight of the water bottle it can’t really be calculated.
Hope this helps!
Complete Question
In the year 1178, five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon, causing a red glow in and around it. It is hypothesized that this event created the crater Giordano Bruno, which is right on the edge of the area we can usually see from Earth.
How long after the asteroid hit the Moon,which is
away ,would the light first arrive on the earth in seconds
Answer:
The time it would take is 
Explanation:
The objective of this question is to obtain the time the light would arrive earth
We are told that the distance from moon to earth is

Now generally time is mathematically represented as

The c here is the speed of light which has a value of 
Now substituting values
