A cylindrical gas bottle has a radius of 4.5 cm and a height of 30.0 cm. The uncertainty in both measurements is 0.1 cm. The directly calculated volume (V = π r2 h) of the bottle is 1908.5 cm3. Using the high/low method, which of the following is the best approximation to the uncertainty in this calculation?
4.5cm^3
0.1cm^3
30cm^3
90cm^3
0.0314cm^3

Aloop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. a loop of wire is in a magnetic field such that its axis is parallel with the field direction. which of the following would result in an induced emf in the loop? choose all that apply. moving the loop outside of the magnetic field region. spin the loop such that its axis does not consistently line up with the magnetic field direction. change the magnitude of the magnetic field. change the diameter of the loop

When barack obama was running for president, at a campaign stop he tried to bowl, something he isn't very good at. the media loved it because he threw a gutter ball while they were all watching. this is an example of:

What happens when the vapor pressure of a liquid is equal to the external pressure?
