A 0.5 kg block lies on a horizontal tabletop. The coefficient of kinetic friction between the block and the surface is 0.25. The block is connected by a massless string to a second, 0.3 kg block. The string passes over a light frictionless pulley as shown above. The system is released from rest.What is the tension force in the string? Please show work

Two gases are contained in gas bulbs con-

nected by a valve. Gas A is present in a 55 L

bulb at a pressure of 372 torr. Gas B exerts

a pressure of 980 torr in a 71 L bulb. What

is the partial pressure of gas B after they

equilibrate once the valve has been opened?

Answer in units of torr

Two gases are contained in gas bulbs con-

nected by a valve. Gas A is present in a 1 liter

bulb at a pressure of 967 torr. Gas B ex-

erts a pressure of 397 torr in a 1 liter bulb.

The valve is opened and the two gases equili-

brate. What is the partial pressure of gas A

expressed after equilibration?

Answer in units of torr

A sample of nitrogen gas is collected over

water at a temperature of 23C. What is the

pressure of the nitrogen gas if the atmospheric

pressure is 734 mmHg?

Answer in units of mmHg

I currently have an andriod and I'm considering buying an at&t iphone 4 for $100, I plan on using it with a different provider. The front screen is cracked a little bit but I plan to change it to a blue screen (I have experience replacing digitizers). Is a 8gb at&t iphone worth $100? Thx
