The mass of the soil sample is 82g.
- The container has a mass of 15g.
- Let the mass of the soil be "x" g.
- The mass of the container and soil combined is 97g.
- container mass + soil mass = total mass
- 15g + x = 97g
- x = 97g-15g
- x = 82g
- The amount of matter that makes up a physical body is known as its mass. It serves as a gauge for the body's inertia.
- The amount of matter that makes up any item or body is the best way to define mass. Everything we see around us is made of mass.
- In physics, mass is the most fundamental characteristic of matter and one of the fundamental quantities. The amount of matter in a body is referred to as its mass. The kilogram is the kilogram, which is the SI unit of mass (kg).

Answer:
Explanation:
The total fluid mass can be obtained by multiplying the mass flow rate by the time flow rate.
Mass flow rate is given as
m = ρAv
Where
m is mass flow rate
ρ is density
A is area and it is given as πr²
v is velocity
Then,
M = mt
Where M is mass and t is time
Them,
M = ρAv × t
M = ρ× πr² × v × t
Given that, .
Radius of pipe is
r = 0.089m
velocity of pipe is
v = 3.3m/s
Time taken is
t = 1 hour = 3600 seconds
Density of water is
ρ = 1000kg/m³
M = ρ× πr² × v × t
M = 1000 × π × 0.089² × 3.3 × 3600
M = 295,628.52 kg
M = 2.96 × 10^5 kg
Answer:
Explanation:
A )
The ball floats with half of it exposed above the water level . So it must have density half that of water . In other words its density must have been 500 kg / m³
B )
Tension in the ball will be equal to net force acting on the ball
Net force on the ball = buoyant force - weight .
4/3 x π x .21³ x 10⁻⁶ x 9.8 ( 1000 - 893 )
= 40.65 x 10⁻⁶ N .
C )Tension in the 3 rd ball will be equal to net force acting on the ball
Net force on the ball = weight - buoyant force
= 4/3 x π x .21³ x 10⁻⁶ x 9.8 ( 1320 - 1000 )
= 121.6 x 10⁻⁶ N .
