Answer:
291 K is the answer
Explanation:
to get Kelvin from Celsius use the following
Kelvin = Celsius +273
= 18 +273
= 291
Answer:
See the explanation below.
Explanation:
Density will remain the same since density is the relationship between mass and volume. As we can see in the equation below.

where:
Ro = density = 2.5 [g/cm³]
m = mass [g]
V = volume [cm³]
In such a way that when the glass is broken the small fragments retain the same density ratio. That is, each fragment has a small mass and a small volume. That's why the density remains the same.
Answer:
the liquid has less height than the mercury
h_{ liquid} = 
Explanation:
The pressure as a function of the height is given by
P = ρ g h
where ρ is the density of the liquid, g the acceleration of gravity and h the height reached by the column of the liquid
In that case they say that the pressure is the standard one that is P = 1.01 10⁵ Pa = 760 mmHg
The first way to give the pressure is in SI units and the second way is the height that the mercury column reaches
In the case of building a barometer with a liquid that has a density greater than that of mercury
ρ_liquid > ρ_Hg
the pressure
P =ρ_lquid g h_liquid
if we have the same pressure
ρ_{Hg} g h_{Hg} = ρ_{liquid} g h_{liquid}
h_{ liquid} =
therefore the liquid has less height than the mercury
Answer:
Acceleration of gravity on Noveria = 4.4 m/s²
Explanation:
Commander Shepard, an N7 spectre for Earth, weighs 799 N on the Earth's surface.
We have weight, W = mg
Acceleration due to gravity, g = 9.81m/s²
799 = m x 9.81
Mass of Shepard, m = 81.45 kg
She lands on Noveria, a distant planet in our galaxy, she weighs 356 N.
We have weight, W = mg'
356 = 81.45 xg'
Acceleration of gravity on Noveria, g' = 4.4 m/s²
