Answer:
Explanation:
According to the Archimedes' Principle, the buoyant force exerted on the helium ballons is equal to the weight of displaced air. A simplified scheme for the system person-ballons is presented below. The correspondent equation of equilibrium is:
The minimum net volume is:
The volume of each ballon is:
The minimum quantity of ballons needed to lift Josiah is:
Answer:
Choices A, B, and C are correct.
Explanation:
Let us look at each of the choices one by one:
A. It is a vector
Yes. Velocity is a vector, or it's a speed with direction.
B. It is the change in displacement divided by the change in time.
Yes. The velocity can be written as
where is the displacement—a vector quantity.
C. It can be measured in meters per second.
Yes. The units of velocity are m/s, but also with a unit vector indicating the direction.
D. It is the slope of the acceleration vs. time graph.
Nope. The velocity is the slope of displacement vs. time graph.
Hence, only choices A, B, and C are correct.
C. Force causes displacement
