A. The IV is the temperature of gas in the balloon.
B. The DV is the volume of the balloon.
This is because the temperature of the gas is the variable being manipulated in the experiment (Independent) and the volume is changing based on the shifts of the temperature (thus volume is Dependent).
40 km/h to in/s
60*60=3600 seconds in an hour
one km is about 0.621 miles
40 km is about 0.621*40=24.84 miles
5280 feet in a mile
12 inches on each foot
5280*12=63360 inches in a mile
63360*24.84=1573862.4 inches in 40km
40 km/h = 40*1573862.4/3600=17487.36 in/s
Answer:
(a) the input force is 36.56 N
(b) the input force is 37.49 N
Explanation:
Given;
density of hydraulic oil, ρ = 8.53 x 10² kg/m³
radius of plunger, r₁ = 0.135 m
radius of piston, r₂ = 5.43 x 10⁻³ m
Part (a) The input force needed to support 22600-N weight, when the bottom surfaces of the piston and plunger are at the same level;
Where;
P is pressure
F is force
A is circular area = πr²
Part (b) The input force needed to support 22600-N weight, when the bottom surface of the output plunger is 1.20 m above that of the input plunger
But, F = PA and A = πr²

Answer:
Persuasive: "Banning all video games is not the answer to reducing violence in our society. People argue that violent games harm our culture and should be banned. However, this action would go against the freedom of choice." "The New York Times reports that over a million students in the United States are now taking courses online. Online learning may be more convenient for students and teachers. However, it appears to be just an attempt by schools to save money." "We must act to preserve the rain forests of the Amazon. According to the World Wildlife Fund, 17 percent of the rain forest has been cleared in the past 50 years."
