The vector sum is the algebraic sum if the two vectors have the same direction.
The sum vector is zero if the two vectors have the same magnitude and opposite direction
Vector addition is a process that can be performed graphically using the parallelogram method, see attached, where the second vector is placed at the tip of the first and the vector sum goes from the origin of the first vector to the tip of the second.
There are two special cases where the vector sum can be reduced to the algebraic sum if the vectors are parallel
case 1. if the two vectors are parallel, the sum vector has the magnitude of the sum of the magnitudes of each vector
case 2. If the two vectors are antiparallel and the magnitude of the two vectors is the same, the sum gives zero.
In summary in the sum of vectors If the vectors are parallel it is reduced to the algebraic sum, also in the case of equal magnitude and opposite direction the sum is the null vector
Answer:
Explanation:
Ohms law says that the current in the conductor between the two points is directly related or directly proportional to the voltage by keeping a proportionality of constant which is called resistance.
Mathematically Ohms law can be written as,
Here, I is the current measure in ampere or amperage, V is voltage measure in voltage and R is resistance measure in Ohm.
Now the relation between the amperage, voltage and resistance will be,
Amperage=Voltage/Resistance
Matter is anything that has mass and takes up space. Substances are types of matter that are pure. Just remember that matter has mass and they both start with "m." Substances are <u>types of matter</u>. Cheers, mimiisawesome5
Answer:
S = 26.58 meters
Explanation:
Given the following data;
Initial velocity = 4.66 m/s
Acceleration = 5.66 m/s²
Time = 2.35 seconds
To find the distance travelled by the object, we would use the second equation of motion;
S = ut + ½at²
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
S = 4.66*2.35 + ½*5.66*2.35²
S = 10.951 + (2.83 * 5.5225)
S = 10.951 + 15.629
S = 26.58 meters
Well, my 5 reasons would be:
The risk factor. The risk of nuclear power would be INSANE, if we had nukes packed in the backs of our cars and got in a car crash, let's just say we wouldn't have roads after that accident.
Nuclear waste. The waste caused by nuclear is outrageous, it stays for hundreds of thousands of years, and we already dump 2,000 metric tons of nuclear waste per year already, if we had a community based on nuclear, it'd be terrible.
The cost would be tremendous, you would have to build tons of sites, hire probably a new military just for it, scientists, everything would make the cost tremendous.
The foreign risk. Think of all the people who walk into America ( terrorists ) and say "Imma' go blast myself a couple o' Americans". Terrorists would have even more reasons to raid areas for Uranium for the money or to build a bomb, if we got one hit with all the plants we would need, it'd probably cause a very large chain reaction destroying part of our country.
Nuclear radiation. If we have nuclear everything everywhere, how are we gonna protect ourselves from the radiation? We gonna go to work in hazmat suits?
Those are my five reasons, hope it helps, if not, comment below please!!!!
