Answer #1

we have total of 1000 g ham and 1200 g bread

one sanwich has 10 g ham and toal of 50 g of bread ( 25 g for each slice)

Therefore, we have 1000 g / 10 g = 100 slices of ham. and 1200 g / 25 g = 48 slices of bread

As each sandwich needs two slices, we will be able to make only 24 sanwiches

Therefore, number of sanwiches we can make is 24.

Mass of one sandwich = 10 + 2*25 = 60 grams

Therefore, mass of 24 sanwiches = 1440 g

what is left over ?

As we were able to make only 24 sandwiches and we had 100 slices of ham, so left over is ham ( 100 - 24 = 76 pieces of ham are left)

Mass of left over ingredient = 76*10 = 760 g

A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 450 grams (0.45 kg), at the ends of a very low mass rod of length d = 50 cm (0.5 m; the radius of rotation is 0.25 m). The barbell spins clockwise with angular speed 120 radians/s. We can calculate the angular momentum and kinetic energy of this object in two different ways, by treating the object as two...

Although the two lines are exactly the same length, the vertical line appears to be much longer. This is a "robust" effect, meaning that even if you know that the lines are the same length and measure them yourself, the vertical one will still look longer. A researcher wants to know if this effect can be overcome with extensive training to correctly see the length of the lines. On average, the population estimate is that vertical lines are 20% longer--so...
