An investigation has been completed, similar to the one on latent heat of fusion, where steam is bubbled through a
container of water. Steam condenses and the lost energy heats the water and container. Given the following data, do
the calculations requested.
50 g
Mass of the aluminum container
Mass of the container and water
250 g
Mass of the water
2009
Initial temperature of the container and water
20°C
Temperature of the steam
100°C
Final temperature of the container, water, and condensed steam 50°C
Mass of the container, water, and condensed steam
261 g
Mass of the steam
119
Specific heat of aluminum
0.22 cal/g°C
Heat energy gained by the water
6,000 cal
4,000 cal
14,000 cal
10,000 cal

Which of these statements is true? a. quarks pair with leptons to form protons and neutrons. b. quarks pair with bosons to form photons. c. quarks pair with photons to form protons and neutrons. d. quarks pair with other quarks to form protons and neutrons. e. quarks pair with electrons to form protons.

This punnett square shows the cross between two pants. one parent has round seeds (rr). and the other parent has wrinkled seeds (rr) which best describes their offspring as shown in this cross?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
