Answer:

10 kilowatts or 10,000 kw

Explanation:

Power = Force × Velocity

Given that:

Velocity of car is 50 m/s

The force is 200N

The power would be:

P = 200 × 50

P = 10,000 W

Notice that it only reaches watts because of the unit of the velocity is m/s. Standard unit to make Kw is km.

Since:

1 kw = 1000 w

10 kw = 10000 w

Credits to the person below me for correction.

Answer:

10 KW

Explanation:

The speed of the car is 50m/s.

The force of 200N is produced.

Power (W) = Velocity (m/s) × Force (N)

Power (W) = 50 × 200

Power (W) = 10000

1 Nm/s = 1 Watt

The power in Watts is 10000. The question asks for the power in kilowatts.

1 kilowatts = 1000 Watts

10000/1000 = 10 kilowatts

Carboxypeptidases can be used to determine the entire sequence of short peptides (<50 amino acid residues) and it starts by r

zepelin [54]

Answer:

A. True

Explanation:

Carboxypeptidases are enzymes which function in the digestion of short peptides known as oligopeptides in the small intestine. Oligopeptides contain between 10 to 50 amino acid residues.

The two carboxypeptidases A and B involved in the digestion of proteins in the small intestine are secreted by the exocrine glands of the pancreas.They are both zinc-containing enzymes which remove successive carboxyl-terminal (C-terminal) residues from oligopeptides until free amino acids are obtained.

Since they function in this way, they can be used to determine the entire sequence of short peptides or oligopeptides.

Draw the addition product formed when one equivalent of hcl reacts with the following diene.

pashok25 [27]

Answer:

Major Product = 4-chloro-4-methylcyclohex-1-ene

Explanation:

Alkene are the class of organic compounds which contain one or more double bonds between two carbon atoms. Alkenes are considered most reactive among the unsaturated hydrocarbons and they undergo addition reactions due to high electron density around the double bonds.

In given question it is written that we are provided with one equivalent of HCl while, our compound contains two double bonds (diene) so in selected starting material the HCl will be added across (hydrohalogenation reaction) the substituted double bond because it will give a more stable carbocation (tertiary carbocation) during the reaction course. Hence, as shown in reaction scheme 4-chloro-4-methylcyclohex-1-ene will be the major product.
