Room temperature is around 25°

c. What is the state of matter of bromine?

Nicholas paddles his canoe downstream from the lodge to the park in 44 hours and then back upstream to the lodge in 55 hrs. If the distance from the lodge to the park is 3030 miles, find Nicholas' speed in still water and the speed of the current.

A spring driven dart gun propels a 10g dart. It is cocked by exerting a force of 20N over a distance of 5cm. With what speed will the dart leave the gun, assuming the spring has negligible mass?

How do Newton's laws of motion apply to the motion of an animal, such as a cat that is running?

All the mass we ever encounter is positive - nothing weighs less than zero. What makes us think charge is different that there are both positive AND negative charges?

Refer to Concept Simulation 4.4 for background relating to this problem. The drawing shows a large cube (mass = 28.9 kg) being accelerated across a horizontal frictionless surface by a horizontal force P. A small cube (mass = 4.

How to reverse the heating effects of electric curent

To protect their young in the nest, peregrine falcons will fly into birds of prey (such as ravens) at high speed. in one such episode, a 600 g falcon flying at 20.0 m/s ran into a 1.50 kg raven flying at 9.00 m/s.

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table. A 2 column table with 4 rows. The first column is labeled spring with entries W, X, Y, Z.

Which type of light travels at the fastest speed? a. none of these b. ultraviolet light c. infrared light d. visible light

How far does a car go in 30 seconds at a speed of 29 m/s?
