Answer:
The correct options are;
C. Alternating current and direct current
E. Electrolyte
Explanation:
Electricity is generated in either AC or DC depending on the source of the energy which aids the electricity generation;
The most common method through which electricity is generated and through which the principle of electric generation was discovered by Michael Faraday, is the rotation of a wire loop or coil between the North and South poles of a magnet to produce Alternating Current
Electricity is also generated in Direct Current by solar cells which convert sunlight into electric energy by photovoltaic effect.
20. Electrolysis is a chemical reaction that is brought about by the application or passing of a direct electric current through an electrolyte, which is an ion containing liquid.

Answer:
The of the lander would be 75.66 pounds
Explanation:
From the question we are given that the
Weight of the Philae on Earth is = 220 pound-mass
gravity of Mars is = 3.71 m/
Weight of the Philae on Mars is = ?
Now Mass is quantity of matter in an object so it is always constant for a particular object
Generally Weight = Mass × Gravity :

Hence
Weight of the Philae on Mars is =

He is correct as many engines are run by diesel. It produces more power as that is how cars produce more power.
Answer:
The average velocity is 0.203 m/s
Explanation:
Given;
initial displacement, x₁ = 20 yards = 18.288 m
final displacement, x₂ = ¹/₃ x 18.288 = 6.096 m
change in time between 5:02 PM and 5:03 PM, Δt = 3 mins - 2 mins = 1 min = 60 s
The average velocity is given by;
V = change in displacement / change in time
V = (x₂ - x₁) / Δt
V = (18.288 - 6.096) / 60
V = 0.203 m/s
Therefore, the average velocity is 0.203 m/s
