Answer:
Potential energy
Explanation:
A mountain climber at the peak of a mountain has potential energy.
The potential energy of a body is stored energy in a body. It is function of mass and position of the body.
Mathematically;
P.E = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Answer:
D. There is no net change to the system
Explanation:
Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.
In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:
A + B ⇌ C + D
This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.
Answer: Option (B) is the correct answer.
Explanation:
Surface tension is defined as the attractive forces experienced by the surface molecules of a liquid by the molecules present beneath the surface layer of the liquid.
And, viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
Since, it is given that viscosity of liquid B is more than liquid A. Therefore, liquid B has more resistive force on its surface as compared to liquid A. As a result, time taken by liquid B is more than time taken by liquid A.
Also, Surface tension = 
Surface tension of liquid B is more than liquid A. Therefore, 
.
Thus, we can conclude that tA will be less than tB.
The theory or relativity. The Big Bang theory (not the show. In science, the big bang theory is a real theory). I know that was two, I just wanted to give you more than one example! Please give me brainiest!
