Answer:
The weight of the parcel is 5 N
Step-by-step explanation:
we know that
Weight can be calculated using the equation:
where
W ----> weight (W) is measured in newtons (N)
m ----> mass (m) is measured in kilograms (kg)
g ----> gravitational field strength (g) is measured in newtons per kilogram (N/kg)
In this problem we have
Remember that
To convert g to kg
Divide by 1,000
so
substitute the values in the equation
therefore
The weight of the parcel is 5 N
The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours. Further, for Mark to be back to the starting point, the total distance covered is 2.75. Dividing the distance by 12 miles per hour, it will take Mark only 0.23 hours. Thus, Mark will reach the initial point first.
To find the thickness of one paper, you set up proportions. 10,000 sheets/85 cm=1 sheet/ x cm. Then you cross multiply and get,
85=10,000x
Then find x,
x=.0085
Or .0085 cm
Another way to find it is just to divide 85 by 10,000 from the start because you need to find the thickness of one paper, not ten thousand.
Hope this helps.
