A 555.0 g/hr stream of liquid methyl alcohol, also called methanol, (CH3OH) at 7.20 atm and 28.0°C was held at constant pressure, vaporized and brought to 241.0°C. At what rate must heat be supplied to this system? Assume that methyl alcohol vapor behaves ideally for the temperature range and pressure given.
Two loudspeakers emit 400Hz notes. One speaker sits on the ground. The other speaker is in the back of a pickup truck, What is the truck's speed in m/s
A u-tube with constant cross section is partly filled with water. Engine oil of density 0.8g/cm3 is poured into the right arm (without mixing) until the water level rises 2.0cm. The length of the oil column is then.
two tuning forks oscillating coherently and in phase at 1200Hz are separated by 0.35m, Calculate the angles of minimum intensity
A 10,000 kg railroad car is rolling at 2 m/s when a 400 kg load of gravel is suddenly dumped in. What is the railroad cars speed just after the gravel is dumped in.
An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. What is the velocity of the more massive fragment
To get back to the shuttle, the astronaut unstraps a 10-kg tool kit and throws it away with a speed of 8 m/s. In the script, the astronaut, who has a mass of 80 kg without the toolkit, survives, but is this accurate.
A projectile is fired straight upward at 141 m/a. how fast is it moving at the instant it reaches the top of its trajectory? Assume in its place that it was fired upward at 45. What would be its speed at the top of its trajectory.
What is the magnitude of the apparent weight of an 80-kg astronaut 5200-km from the center of the Earth's Moon in a space vehicle moving at constant velocity.

A 2.46×10^4 rocket blasts off vertically from the earth's surface with a constant acceleration. Throughout the motion considered in the problem, suppose that remains constant. Inside the rocket, a 15.10 instrument hangs from a wire that can support a..
The displacement of an object moving under uniform acceleration is some function of time and the acceleration. Suppose we write this displacement as s=ka^mt^n, where k is the dimensional constant. Show by dimensional analysis that this expression ..
