6. a) A rectangular box completely filled with milk powder is 16 cm long, 9 cm broad and 15 cm high. How many cubical boxes of length 6 cm are required
to empty the milk powder from the box?

10

Step-by-step explanation:

Step 1:

Find the volume of the rectangular box

Volume = L x H x W

L = 16cm, W = 9cm and H = 15cm

Step 2: Substitute in the formula

Volume of the rectangular box = 16 x 9 x 15 = 2160 cm cube

Step 3: Find the volume of the cubical box

Step 4: To find the number of cubical boxes of length 6cm required to empty the milk powder from the box, you will divide volume of the rectangular box by the volume of the cubical box

Therefore

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
