Answer: 131.92 m
Explanation: The problem give above is a conversion problem. To convert any measurement from one unit to another, we need a relation for the original units to that of the desired unit. This relation is called the conversion factor. It is used by multiplying or dividing the factor depending on what is the unit of the original measurement. For this case, we need to convert from ft^2 to m^2. The conversion factor would be 1 foot is equal to 0.3048 m. So, we would be getting the square of the factor and then multiply to the original value.
1420 ft^2 ( 0.3048 m / 1 ft)^2 = 131.92 m
Answer:
20.65 m/s
Explanation:
You are gonna wanna use a calculator for this one
so we will write all the known variables:
h = 15.6 m
initial velocity (u) = 10.7 m/s
acceleration (a) = 10 m/s/s (gravity)
From the third equation of motion:
<em>v² - u² = 2ah</em>
<em>v² - (10.7)² = 2(10)(15.5)</em>
<em>v² - (10.7)² = 312</em>
<em>v² = 312 + 114.49</em>
<em>v² = 426.49</em>
v = 20.65 m/s
Answer:
A. 10 N
B. 20 N
C. 1,000 N
Explanation:
D. According to Newton's Third Law, in the simplest terms, each and every action (force) has an equal but opposite reaction. So when the air pushes out to the left, the pressure of the air being released propels the balloon to the right. Therefore, Newton's Third Law is followed in this scenario. That is the same case for the above three questions as well.
