Answer: 0.001m^3
Explanation:
Given the following :
Mass of tub = 0.650kg
Mass of rock = 0.350kg
In this scenario:
Upthrust is the weight of fluid displaced
Upthrust = Total weight of tub (since the tub floats, and top of tub is level with the water line )
Recall Weight = mass * acceleration due to gravity(g)
g = 9.8m/s
Total mass = (0.650 + 0.350)kg = 1kg
Weight = 1kg × 9.8m/s = 9.8N
Upthrust = 9.8N
Recall: Upthrust = Density × acceleration due to gravity(g)× displaced body volume of fluid
Density of water = 1000kg/m^3
g = 9.8m/s^2
9.8N = 1000 × 9.8 × Volume
9.8 = 9800V
V = 9.8 / 9800
V = 0.001m^3
Answer:
Explanation:
As we know that
PV = nRT
here we have
so we have
T = 290 K
now we have
now the mass of gas is given as
now density of gas when its volume is increased to 3.3 L
so we will have
Answer:
Answer:
the amount of energy flowing is 1.008x10⁹J
Explanation:
To calculate how much heat flows, the expression is the following:
Where
K=thermal conductivity=0.81W/m°C
A=area=6.2*12=74.4m²
ΔT=30-8=22°C
L=thickness=8cm=0.08m
t=time=16.9h=60840s
Replacing:
Explanation:
From the word compound, the compound machine is already a combination of two or more types of simple machine. Thus, the answer is letter C. Because of its complexity, it is able to perform several other functions than a simple one.
