Answer:
,Mass of the Body = 10 kg.
Height = 10 m.
Acceleration due to gravity = 9.8 m/s².
Using the Formula,Potential Energy = mgh
= 10 × 9.8 × 10 = 980 J.
(b). Now, By the law of the conservation of the Energy, Total amount of the energy of the system remains constant.
∴ Kinetic Energy before the body reaches the ground is equal to the Potential Energy at the height of 10 m.
∴ Kinetic Energy = 980 J.
(c). Kinetic Energy = 980 J.
Mass of the ball = 10 kg.
∵ K.E. = 1/2 × mv²
∴ 980 = 1/2 × 10 × v²
∴ v² = 980/5
⇒ v² = 196
∴ v = 14 m/s.
Answer:
b
Explanation:
because of the law of cause and effect change a small part of a structure change the whole thing
The main function of the PNS is to connect the CNS to the limbs and organs. The PNS sends information to the CNS as quickly as possible.
I hope this helps :)
The correct answer is 'a'. Energy is released as atoms are combined.
It will take 1,000,000 times slower for Hydrogen Peroxide to decompose
Hydrogen peroxide is a toxic compound that usually destroys cell membrane. Also, it is a byproduct of metabolism that must be broken down quickly because it can cause damage to the cells. Moreover, catalase is an enzyme that is found in almost all the living organism and function by catalysing the decomposition of hydrogen peroxide into water and oxygen. However, the decomposition of hydrogen peroxide is very slow and cannot sustain human life in the absence of catalase.
