Answer:

K.E. increase by 10 KJ.

Explanation:

Total mechanical energy of a system is always constant which is the sum of kinetic and potential energies of the system. So, when the ram of a pile driver when it suddenly undergoes a 10 kJ decrease in potential energy, its kinetic energy must have increase by 10 KJ. So, as to make their sum constant again.

Mechanical energy = Kinetic energy + potential energy = constant

2. Which energy source is considered a non-renewable resource?
Keith_Richards [23]

Answer:

The answer is D

Explanation:

Although natural processes continually form fossil fuels, such fuels are generally classified as non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made. ... The use of fossil fuels raises serious environmental concerns.

90 minutes is 1.5 hours.

5 kW * 1.5 hours = 7.5 kWh

8c/kWh * 7.5 kWh = 60 cents

Butane (c4h10) is liquid fuel used in lighters. how many grams of carbon are in a lighter containing 7.25 mL of butane? The dens
Alisiya [41]
Density = 0.601 g/mL

Volume = 7.25 mL

D = m / V

0.601 = m / 7.25

m = 0.601 x 7.25 => 4.35725 g

When two carbon atoms are joined by a double bond, how many electron pairs are shared between the two carbons
NikAS [45]

Answer:

Two (2) electron pairs

Explanation:

The sharing of electron pairs by atoms forms a type of bond called COVALENT bond. Atoms that form covalent bonding (share electrons) do so in order to fill their outermost electron shells, hence, gain chemical stability.

However, when two atoms like carbon share TWO PAIRS of electrons with each other, a DOUBLE BOND is formed. An example is the double bond formed in Ethylene (2HC=CH2). A total of four valence electrons (a pair from each carbon) are shared between the two carbon atoms.
