Both positive and negative charges will spread the leaves of an uncharged electroscope.

a) True

b) False

If the splash is heard 1.17 seconds later, what was the initial speed of the rock? Take the speed of sound in the air to be 343 m/s.|v0|=nothingm/s.

If the temperature at the surface of earth (at sea level) is 40°c, what is the temperature at 2000 m if the normal lapse rate is 6.4°c/1000 m?

As heat is added to water, is it possible for the temperature measured by a thermometer in the water to remain constant?

An object falls because of gravity at a rate of - 980 cm/s2 ( - sign is indicative of a downward direction) for 10. seconds. If it starts from rest (vo = 0) and its position starts from do = 0.0, where is it 10. seconds later? -4900 -49 -490

The diagrams above were used to illustrate the arrangement of the particles of a substance in three different states of matter.

What is energy? it's from my physics book

An object is thrown upward with a speed of 12 m/s on the surface of planet x where the acceleration due to gravity is 1.5 m/s2. how long does it take for the object to reach the maximum height?

How fast must a 0.142-kg baseball move in order to have the same momentum as the bus?

What is resistance? Difference between resistance and resistivity.

What is meant by the statement, "a thermometer measures its own temperature"?
