Answer:
Induced current, I = 0.5 A
Explanation:
It is given that,
number of turns, N = 20
Area of wire, 
Initial magnetic field, 
Final magnetic field, 
Time taken, t = 2 s
Resistance of the coil, R = 0.4 ohms
We know that due to change in magnetic field and emf will be induced in the coil. Its formula is given by :
Where
Let I is the induced current in the wire. It can be calculated using Ohm's law as :
I = 0.5 A
So, the magnitude of the induced current in the coil is 0.5 A. Hence, this is the required solution.
Answer:
A. Gasoline
B. Apple juice
Explanation:
A homogeneous mixture can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture.
For instance, aqueous hydrogen chloride, HCl(aq) is a homogeneous mixture. The aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride. This ultimately implies that, aqueous hydrogen chloride HCl(aq) is a solution of hydrogen chloride in water and it is commonly referred to as Hydrochloric acid.
Hence, the two mixtures that are homogeneous are gasoline and apple juice.
Answer:
The process
Explanation:
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
The mass of the object doesn't matter. The change in its momentum is equal to the impulse that changed it ... 15 N-sec.
Kinetic energy is the energy an object has due to its motion.
