Answer:
3333.33 kg/m³
Explanation:
Density: This can be defined as the ratio of the mass of a body to its volume.
The unit of density is kg/m³.
From Archimedes principle,
R.d = W/U = D/D'
Where R.d = relative density, W = weight of the object in air, u = upthrust in water, D = Density of the object, D' = Density of water.
W/U = D/D'
making D the subject of the equation
D = D'(W/U).......................... Equation 1
Given: W = 5.0 N, U = 5.0 -3.5 = 1.5 N, D' = 1000 kg/m³
Note: U = lost in weight = weight in air - weight in water
Substitute into equation 1
D = 1000(5/1.5)
D = 3333.33 kg/m³
Thus the density of the object = 3333.33 kg/m³
Answer:
See the explanation below
Explanation:
<u>First example</u>
The water contained in a lake or tank is in equilibrium there is no movement of the fluid and the water exerts pressure on the bottom of the tank or lake.
<u>Second example</u>
A floating buoy that is on the high seas, the buoy is in static equilibrium and these developed forces allow the buoy not to sink.
<u>Third example</u>
A hydraulic press which uses the principle of pascal and the mechanical advantage due to the relation of areas, where applying a smaller force, you can obtain a much greater force, communicating the energy through a fluid such as oil.
<u>Fourth Example</u>
The atmospheric pressure, which depends on the height of a place above sea level, in this case the fluid is the air. Although the air cannot be seen, it exerts a pressure column on the bodies on the Earth's surface.
Answer:
The answer to your question is D An annual weather pattern
Explanation:
Answer:
After 2 seconds the velocity of the object is 0 m/s.
Explanation:
The velocity at 2 seconds later can be calculated as follows:
Where:
: is the velocity at 2 seconds
: is the initial velocity = 20 m/s
g: is the gravity = 10 m/s²
t: is the time = 2 s
Hence, the final velocity is:
This value (0 m/s) means that the object has reached the maximum height.
Therefore, after 2 seconds the velocity of the object is 0 m/s.
I hope it helps you!
