Answer:
T=75N
Explanation:
In order to solve this problem, we must first start by drawing a free body diagram (see attached picture).
Once we got the free body diagram, we can do an addition of forces so we get:
it equals zero because it's at equilibrium.
So the sum of forces in this case will be:
so now we solve for the tension T:
we need to figure out what W is equal to. But in order to do that, we need to figure out what the volume of the glass is. We know the buoyant force is calculated by multiplying the volume displaces by the density of water and the acceleration of gravity, so we get:
So the volume of the glass will be:
we know the density of water is
so our volume is:
Now we can calculate the weght of the piece of glass, so we get:
W=125N
and now we can calculate the tension:
T=125N-50N
T=75N

Cementation is the process in which dissolved minerals crystallize and glue particles of sediment together.
Answer:
1.6031 miles
Explanation:
Given the following data;
Speed = 344 m/s
Time = 7.5 seconds
To find how many miles away was the lighting strike;
Mathematically, the distance travelled by an object is calculated by using the formula;
Distance = speed * time
Distance = 344 * 7.5
Distance = 2580 meters
Next, we would have to convert the value of the distance travelled in meters to miles;
Conversion:
1609.344 metres = 1 mile
2580 meters = X mile
Cross-multiplying, we have;
X * 1609.344 = 2580
X = 2580/1609.344
X = 1.6031 miles
