The lengths of rods a and b are 120cm and 96cm respectively. after a rod of equal length is cut from each rod, the ratio of the length of a to that of b becomes 10 : 7. find the length of the rod cur from a

The length of rod cut from A is 40 cm

Solution:

Given that,

length of rod A = 120 cm

length of rod B = 96 cm

After a rod of equal length is cut from each rod, the ratio of the length of a to that of b becomes 10 : 7

Let "x' be the length of rod cut from rod A and rod B

After that, now length becomes,

length of rod A = 120 - x

length of rod B = 96 - x

Their ratio is equal to 10 : 7

Therefore, we get

Thus the length of rod cut from A is 40 cm

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
