Answer:
water sample have more water content
Explanation:
given data
soil 1 is saturated with water
unit weight of water = 1 g/cm³
soil 2 is saturated with alcohol
unit weight of alcohol = 0.8 g/cm³
solution
we get here water content that is express as
water content = 
....................1
here soil is full saturated so 
is 100% in both case
so put here value for water
water content = 100 % × 1
water content = 1 g
and
now we get for alcohol that is
water content = 100 % × 0.8
water content = 0.8 g
so here water sample have more water content
Answer:
Yes, it is Reasonable.
Explanation:
The problem states that by using a new sensor, the result is 60 million dynes.
Converting the force into Newtons, by using the formula,
1 newton = 10⁵ dynes,
i.e, 1 million dynes = 10 newtons.
we get,
60 million dynes = 60 x 10 newtons = 600 newtons.
The result using a new sensor is reasonable because atmosphere exerts a force of about 10 newtons on us and 600 newtons is just 60 times of it.
Thus 600 N can be applied by the hammer on the nail and it is reasonable.
Answer: 0.306 kg/s
Explanation:
If we assume that the specific heat for all stream is constant, we can then say, the mass flow rate of cold water can be calculated by using the energy balance equation.
The energy balance equation basically states that, the heat gained is equal to the heat lost
m'1h1 + m'2h2 = m'3h3
m'1T1 + m'2T2 = (m'1 + m'2) T3
0.5 (60) + m'2(10) = (0.5 + m'2)41
30 + 10m'2 = 20.5 + 41m'2
30 - 20.5 = 41m'2 - 10m'2
9.5 = 31m'2
m'2 = 9.5 / 31
m'2 = 0.306 kg/s
