False
Explanation:
Answer:
38.6%
Explanation:
Molar mass of KNO3 is
=39+14+(16*3)
=53+48
=101 g/mol
Now
Percentage composition of potassium in KNO3 is=(atomic mass of K*no. of atoms)/molar mass of KNO3 *100%
%age composition of K= (39*1)/101 *100%
=0.386*100%
=38.6%
Element Symbol Mass Percent
Nitrogen N 13.854%
Oxygen O 47.474%
Potassium K 38.672%

Answer:
Ampere
Explanation:
The system.international unit of current is ampere.
Answer:
SI unit of electric current is Ampere
Explanation:
The unit described by System International (SI) for electric current is Ampere which is denoted by symbol A.
1 Ampere= 1 coulomb / sec
1 ampere current is drawn when 1 Coulomb of charge passes through a conductor in 1 sec,
Answer:
Ampere
Explanation:
In SI system of measuring quantities, the unit of current is ampere
Answer:
SI unit of current is ampere

Answer:
The answer is (D) It is permeable and water flows through it. I took the test and the answer was (D).
hope it helps
Answer:
The unsaturated zone is also called as vedose zone. It is a zone that lies above the ground water table. It includes the subsurface layers of soil. ... Hence, this can be said that unsaturated zone is not filled by water because it is permeable and water flows through it.
Explanation:
The volume increases when the balloon temperature increases.
Explanation:
-10 F is converted into Kelvin as 249 K.
0°C is nothing but 0+ 273 = 273 K
And the room temperature is 25°C which is converted into Kelvin as 273 + 25 = 298 K.
249 K is below room temperature.
As per the Charles' law volume and temperature are directly proportional to each other, when the pressure of the gas remains constant.
V ∝ T
As the balloon temperature increases, the volume also increases.
Answer:
D
Explanation:
Every enzyme has a specific substrate to bind with.
E.g.
Protien is broken down by protease enzyme
Here -10F represents a colder temperature. The concept charle's law is used here. When we walk outside into -10F temperatures the volume of the balloon decreases. The correct option is C.
The Charle's law states that at constant pressure, the volume of a given mass of gas is directly proportional to the temperature on Kelvin scale. The law can be mathematically expressed as:
V = constant × T or V/T = constant
If we take a balloon outside on a cold winter day, which means in a very low temperature, the volume of the gas inside the balloon also decreases due to the very low temperature.
The Charle's law can also be explained as follows: At a particular temperature which is called the absolute zero, the volume of all gas will become zero. This temperature is - 273°C.
Thus the correct option is C.

Answer:
D) Potential Energy
Explanation:
The compressed spring has elastic potential energy. If it is allowed to de-compress, the elastic potential energy will be converted to kinetic energy.
Answer:
D
Explanation:
Potential energy because a compressed spring has the energy possessed due to position and when the spring is allowed for rarefaction the energy is changed to kinetic energy
