Rank these scenarios on the basis of the angle of the first interference maximum. a. difraction grating with 1000 lines/cm
b. single slit slide with width .04mm
c. single slit slide with width .01mm
d. double slit slide with spacing .08mm
e. diffraction grating with 500 lines/cm
f. double slit slide with spacing .02mm

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.
