An airplane (mass 1865 kg) starts out sitting on a runway at sea level, at rest. It then climbs to a cruising altitude of 2420 m

eters and a constant cruising speed of 96.5 m/s. Assuming no force from air resistance, what work did the engine have to do in order to let the plane reach that height and that speed

Answer:

44.28MJ

Explanation:

Work is said to be done if the force acting on an object causes the object to move through a distance.

Work done = Force × distance

Given mass of airplane = 1865kg

Force = mg = 1865×9.81

Force = 18295.65N

Distance covered = 2420metres.

Work done by the engine = 18295.65×2420

Work done by the engine = 44,275,473Joules

= 44.28MJ

The total charge that passes through an electrolytic cell is given by the product of?
Sergeu [11.5K]

The total charge that passes through an electrolytic cell is given by the product of current and time.

An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy (voltage applied between two electrodes) to drive a chemical reaction that would not otherwise occur. This is in contrast to a galvanic cell, which itself is a source of electrical energy and the foundation of a battery.

The net reaction taking place in a galvanic cell is a spontaneous reaction, i.e. the Gibbs free energy remains negative, while the net reaction taking place in an electrolytic cell is the reverse of this spontaneous reaction, i.e. the Gibbs free energy is positive.

An electrolytic cell has three components: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved.

Molten salts such as sodium chloride can also function as electrolytes. When driven by an external voltage applied to the electrodes, the ions in the electrolyte are attracted to an electrode with the opposite charge, where charge-transferring (also called faradaic or redox) reactions can take place.

Only with an external electrical potential (i.e., voltage) of correct polarity and sufficient magnitude can an electrolytic cell decompose a normally stable, or inert chemical compound in the solution. The electrical energy provided can produce a chemical reaction which would not otherwise occur spontaneously.

The axis of the earth is<br> Tilted about 23.5 degrees<br> Vertical<br> Vertical
melisa1 [442]

Answer:

The axis of rotation of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane of our planet's orbit around the sun. The tilt of the Earth's axis is important, in that it governs the warming strength of the sun's energy.
