Answer:
Given, Mass of an object, m = 2kg
velocity, v = 2m/s
We have,
KE = 1/2 m v²
= 1/2 × 2 (2)²
= 1/2 × 8
= 4J
Hence, 4J is the required Kinetic energy.
Answer:
Hg(NO3)2 + Na2CO3 --> 2NaNO3 + HgCO3
Answer:
b consumers eat producers
Explanation:
In a food chain, the consumers are living organisms that eat organisms from a different population. Examples are herbivores like goats.
Producers make their own food in the food chain. Examples are plants.
The relationship between consumer and producers is hence that consumers consume / eat producers. Goats eat grass.
The correct option is;
b consumers eat producers
Answer:
= 62.1 hours
Explanation:
Energy provide by the serving is 65 cal
= 65 cal × 4.184 Kj = 271.96 kJ
271.96 KJ = 271960 J
Energy required for 1minute of energy
= 73 x 1
= 73 J/min
So, 271960 joules will be required for 271960 heart beat
Minutes = 271960 / 73
= 3593.94 minutes
Time in hours = 3725.429 / 60
= 62.1 hours
True is correct answer.
Polymerization is the process of linking it has a smaller molecules to form has a long chains of higher molecular weight.
Hope it helped you.
