Electrons are the right subatomic particle
Answer:
Meteorites have comparatively huge size than the size of the meteors
The meteorites are originated as the debris from an a comet, asteroid, or meteoroid due to a heavy impact. Whereas, the meteors are the dust formed from an asteroids.
Explanation:
The difference between the meteorites from the meteors is that, the meteorites have comparatively huge size than the size of the meteors. Also, the meteorites are capable enough to survive moving through the earth's atmosphere. while the meteors burns up due to heat produced by the friction while moving in the earth's atmosphere.
The meteorites are originated as the debris from an a comet, asteroid, or meteoroid due to a heavy impact. Whereas, the meteors are the dust formed from an asteroids.
<u>Answer:</u>
The time taken for the ball to hit the floor as 1.02 seconds
<u>Explanation:</u>
As per the given question, the ball leaves at a speed from the table with an initial velocity of 10 m/s, we have the equation
where Vf represents the final velocity
Vi represents the initial velocity
a represents the acceleration and
t represents the time
after rearranging
= 1.022 seconds
Answer:
The value is 
Explanation:
Generally the relative speed at which you are moving with respect to the person ahead of you is mathematically represented as
substituting 1.05 m/s for 
and 2.75 m/s for 
So
=> 
Generally the distance by which the person is ahead of you is mathematically represented as
substituting 18.5 s for 
=>
Answer:
A. False
B. False
C. True
D. True
E. True
F. True
Explanation:
A. The equation Ax=b is referred to as a matrix equation and not vector equation.
B. If the augmented matrix [ A b ] has a pivot position in every row then equation Ax=b may or may not be consistent. It is inconsistent if [A b] has a pivot in the last column b and it is consistent if the matrix A has a pivot in every row.
C. In the product of Ax also called the dot product the first entry is a sum of products. For example the the product of Ax where A has [a11 a12 a13] in the first entry of each column and the corresponding entries in x are [x1 x2 x3] then the first entry in the product is the sum of products i.e. a11x1 + a12x2 +a13x3
D. If the columns of mxn matrix A span R^m, this states that every possible vector b in R^m is a linear combination of the columns which makes the equation consistent. So the equation Ax=b has at least one solution for each b in R^m.
E. It is stated that a vector equation x1a1 + x2a2 + x3a3 + ... + xnan = b has the same solution set as that of the linear system with augmented matrix [a1 a2 ... an b]. So the solution set of linear system whose augmented matrix is [a1 a2 a3 b] is the same as solution set of Ax=b if A=[a1 a2 a3] and b can be produced by linear combination of a1 a2 a3 iff the solution of linear system corresponding to [a1 a2 a3 b] takes place.
F. It is true because lets say b is a vector in R^m which is not in the span of the columns. b cannot be obtained for some x which belongs to R^m as b = Ax. So Ax=b is inconsistent for some b in R^m and has no solution.
