Answer:
A. 2.36 Newtons
Explanation:
F = GmM/d²
F = 6.673 x 10⁻¹¹(1)(5.98 x 10²⁴) / (1.3 x 10⁷)²
F = 2.36121...
Very poor question design.
mass of box... 1 significant digit
distance... 2 significant digits
mass of earth... 3 significant digits
value of G... 4 significant digits
Answer precision to 3 significant digits is not justifiable
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
