Why is salt water a better conductor of electricity than river water?

What is the mass of an object if a force of 34 N produces an acceleration of 4 m/s^2?

A 3.0-kg object moves to the right at 4.0 m/s. It collides head-on with a 6.0-kg object moving to the left at 2.0 m/s. Which statement is correct? A) The total momentum both before and after the collision is zero.

A loop of wire is placed in a perpendicular magnetic field. Suddenly, the magnitude of the magnetic field begins to increase, what is the direction of the induced current in the loop

What does the position of lithium (Li) on the periodic table tell you about its tendency to react with other elements?

A 0.100 kilogrom apple hangs 1.5 meter above the ground. Ignroing frictional effects, the total mechanical energy of the apple is?

How much energy (in joules) is required to evaporate 0.0005 kg of liquid ammonia to vapor at the same temperature?

It is 5.5 km from your home to the physics lab. As part of your physical fitness program, you could run that distance at 10 km/h (which uses up energy at the rate of 700 W), or you could walk it leisurely at 3.0 km/h (which uses energy at 290 W).

The largest volcanic structures on venus are called:

a block with a mass of 3 kg is swung on a cord in a horizontal circle with a radius of 2m. the speed of the block is 6m/s^. the magnitude of the acceleration of the block is most nearly

A scientific theory becomes more widley accepted as it explains more and more?
