Two ways of defining velocity

The expected life of most lead-acid batteries is

Identical + 7.67 μC charges are fixed to adjacent corners of a square. What charge (magnitude and algebraic sign) should be fixed to one of the empty corners, so that the total potential at the remaining empty corner is 0 V?

Which material is likely to experience a nearly elastic collision?

Near Earth, the density of protons in the solar wind (a stream of particles from the Sun) is 11.6 cm-3, and their speed is 563 km/s. (a) Find the current density of these protons.

Rolf is comparing four solutions. solution a was placed in the fridge, which is at 4° c. solution b was placed at room temperature, which is 20° c. solution c was placed in an incubator at 37°c, and solution d was boiled at 100° c.

What is the velocity of the car, in meters per second, just after it hits a 135-kg deer initially running at 10.5 m/s in the same direction? Assume the deer remains on the car.

True or false the metric unit used to describe weight as a measure of the force of gravity is called a newton

One car travels 40. meters due east in 5.0 seconds, and a second car travels 64 meters due west in 8.0 seconds. During their periods of travel, the cars definitely had the same

When an object slides down an inclined plane, the angle between the displacement and the force of gravity is the same as the angle that the surface makes with the horizontal. Suppose you have a 2-kg cart rolling a distance of 1.

An objects speed is 2.40 m/s, and its momentum is 120.0 kg m/s. what is the mass of the object?
