when current is reversed in the direction the force due to magnetic field is also reversed
As we know that the formula of force will be given as
so here if the direction of current is reversed the the force vector also reverse its direction
So we will have the direction of force is also reverse and it will move downwards now
This is the order of the spectrum from highest frequency to lowest frequency:
Gamma Ray (Highest energy em wave)
X Ray (Used in medical imaging)
Ultra violet (dangerous to human skin)
visible light (human eye can see)
Infrared (medium frequency)
Microwave (used to heat food)
Radio (longest wavelength)
Answer: The Central Limit Theorem
Explanation:
The description above explains the central limit theorem which states that given a population having mean U and standard deviation S, and drawing different large sample sizes from the population with replacement, then the distribution of the sample means will be normally distributed approximately and that this condition will be the case whether the distribution is skewed or normal.This hold if the sample size n is at least 30.
A pure substance.
Pure substances have both physical and chemical properties, for example, pure substances have melting points and boiling points, solubility, desnity, etc.
Have a great day, and glad I could help!
Answer:
Nuclear fusion
Explanation:
This is because main sequence of star is powered by fusion of hydrogen to helium atoms together and this process releases energy. The energy released when the gas collapse into a protostar make the center of the protostar to be extremely hot. When the core becomes very hot, nuclear fusion can start.
