Answer:
Bellow
Explanation:
You have the detailed explanation on the other answer
2) 6÷2.2= 2.72 kg
3) 42.5÷2.2= 19.31 kg
19.31 - 9.6= 9.71 kg difference
4) 700÷2.2 = 318.18 kg
5) now is a bit different
2.2 lbs _____1kg
X lbs _____14.6 kg
2.2×14.6 =32.12 lbs
6) 2.2×1.4=3.08 lbs
It protects in the food and other things in our everyday society
We don't really understand what "ball really is life" means, but
judging by the overall group of questions you posted today, one
can be pretty sure that this one is equally meaningless.
Soap bubbles and balloons are also spheres, but have no influence
on the nature of life.
Answer:
v = 4 m / s
Explanation:
In this exercise we are asked to find the speed of the wave, which is described by the expression
v = λ f
in this case the wave has 4 nodes and 3 antinodes, in a length of 12 m
for a standing wave it is satisfied that we have a full wavelength and a half of another
L = λ + ½ λ
L = λ
λ = ⅔ L
Cambien indicates that it has a frequency of
f = 0.5 Hz
we substitute
v = ⅔ L f
let's calculate
v = 12 0.5
v = 4 m / s
Answer:
change in length is 3.397 cm
Explanation:
Given data
long = 91 m = 9100 cm
coefficient for concrete (a) = 1.2 × 10−5 ( ◦C)−1
temperature = 56 F = (56× 5/9) ◦C
to find out
how much spacing is needed to allow
solution
we know allow space is given by this formula
change in length = coefficient for concrete × given length × temperature .............1
put all value in equation 1
change in length = 1.2 × 10−5 × 9100 × (56× 5/9)
change in length = 3.397 cm
so change in length is 3.397 cm
