Explanation:

Electrostatic induction, also known as "electrostatic influence" or simply "influence" in Europe and Latin America, is a redistribution of electric charge in an object, caused by the influence of nearby charges.[1] In the presence of a charged body, an insulated conductor develops a positive charge on one end and a negative charge on the other end.[1] Induction was discovered by British scientist John Canton in 1753 and Swedish professor Johan Carl Wilcke in 1762.[2] Electrostatic generators, such as the Wimshurst machine, the Van de Graaff generator and the electrophorus, use this principle. Due to induction, the electrostatic potential (voltage) is constant at any point throughout a conductor.[3] Electrostatic Induction is also responsible for the attraction of light nonconductive objects, such as balloons, paper or styrofoam scraps, to static electric charges. Electrostatic induction laws apply in dynamic situations as far as the quasistatic approximation is valid. Electrostatic induction should not be confused with Electromagnetic induction

Answer:

a = (v² – v₀²)/ 2(s – s₀)

Explanation:

v² = v₀² + 2a (s – s₀)

We can make 'a' the subject of the above expression as follow:

v² = v₀² + 2a (s – s₀)

Subtract v₀² from both side

v² – v₀² = v₀² + 2a (s – s₀) – v₀²

v² – v₀² = v₀² – v₀² + 2a (s – s₀)

v² – v₀² = 2a (s – s₀)

Divide both side by (s – s₀)

(v² – v₀²)/ (s – s₀) = 2a

Divide both side by 2

(v² – v₀²)/ (s – s₀) ÷ 2 = a

(v² – v₀²)/ (s – s₀) × 1/2 = a

(v² – v₀²)/ 2(s – s₀) = a

a = (v² – v₀²)/ 2(s – s₀)

What formula do I use for the second question? For number 3 how is one energy converted to the other? ( using arrows ) I get num

Fed [463]

#2
Use the formula ... Kinetic energy = (1/2) x (mass) x (speed)²

#3 - a).
sun => energy travels as electromagnetic waves => reaches Earth as
 heat & light energy.

sun => absorbed in plants => eaten by animals => animals die =>
 decay into oil in millions of years => we burn the oil to get the energy.

#3 - b).
food I ate for lunch => metabolized into glucose by my body
 => some of it burned in my muscles to generate energy for immediate needs
 => the rest of it stored as fat for future needs.

#3 - c).
flower pot rolls off the ledge => gravity does work on it all the way down,
 producing the kinetic energy it has when it hits the floor.

#3 - d).
oil or natural gas is burned, releasing heat energy => energy is used
 to generate electricity => electricity flows through cables from the
 power generating plant to your home => hot plate plugged into the
 wall => turns electrical energy back into heat energy => heat energy
 is conducted into the bottom of the beaker, flows through the glass
 to the inside surface => heat energy is conducted from the inside of
 the glass to the water, which gets hotter as it absorbs more energy.
=============================

Note:
#1 on the sheet is wrong.
"Work = force x distance" that's correct
But 25-kg is the mass of the ball, not the gravitational force on it.
The force on it is (mass) x (gravity), called its "weight".
 That's (25-kg) x (9.8 m/s²) = 245 kg-m/s² = 245 newtons .
