In order to calculate the unknown reaction force, we need to know that the sum of forces pointing down is equal the sum of the forces pointing up, so all forces will be in equilibrium.
So we have:
Answer:
the cell is the smallest unit
Using the mirror formula.
1/v + 1/u = 1/f
1/9.5 + 1/3.2 = 1/f
1/f = 3.2 + 9.5 / 9.5 * 3.2
1/f = 4.82 cm
Radius = 2f
Radius = 2 x 4.82
Radius = 9.64 cm
Answer:
Yes it is true saying that 2nd applience use more power than first one
Answer:
92.397amu
Explanation: The exact amu of the mystery element is obtained by multiplying the relative abundance of each individual isotope by its respective amu and then summing the results.
The sum of the total relative abundance for all the isotopes should be 100%.
However, the relative abundance of the isotope with 95.502amu is not given; therefore to obtain it we subtract the sum of the known relative abundances from 100% as follows:
Relative abundance of isotope with 95.502amu = 100-(23.63+30.53) = 42.84%
