Why does the water in the canals of Venice look clearer?

A particle moves along a line so that its position at any time is t>0 or t=0 is given by the function s (t) = (t^3) - (6t^2) + (8t) + 2 where s is measured in meters and t is measured in seconds. a) find instantaneous velocity at any time t.

A solenoid has a cross-sectional area of 6.0 3 1024 m2, consists of 400 turns per meter, and carries a current of 0.40 A. A 10-turn coil is wrapped tightly around the circumference of the solenoid. The ends of the coil are connected to a 1.

An object becomes charged when the atoms in the object gain or lose A protons B neutrons C electrons D all of the above

How do galaxies vary?

Explain the difference between speed and velocity

A uniformly charged thin ring has radius 15.0 cm and total charge 23.5 nC. An electron is placed on the ring's axis a distance 30.5 cm from the center of the ring and is constrained to stay on the axis of the ring.

Some people refer to nuclear power as "clean energy." Why do they make this argument? Do you agree or disagree? Explain your answer.

What does thermal energy mean?

Oil having a density of 924 kg/m 3 floats on water. A rectangular block of wood 3.79 cm high and with a density of 970 kg/m3 floats partly in the oil and partly in the water. The oil completely covers the block.

Where does the energy that is used to ride a bicycle up a hill come from and how is it classified?
