Answer:
V = 6.36 m³
Explanation:
For this exercise we will use fluid mechanics relations, starting with the continuity equation.
Let's write the flow equation
Q = v₁ A₁
The area of a circle is
A = π r²
Radius is half the diameter
A = π/4 d²
Q = v₁ π/4 d₁²
Q = π/ 4 15 0.03 2
Q = 0.0106 m3 / s
The volume of water in t = 10 min = 10 60 = 600 s
Q = V / t
V = Q t
V = 0.0106 600
V = 6.36 m³
A horizontal line means the object is. not changing its position it is not moving, it is at rest.
Answer:
6 centimeter = 60 millimeter
Explanation:
1 meter = 100 centimeter
1 centimeter = 0.01 meter
Thus, 6 × 1 centimeter = 6 × 0.01 meter
6 centimeter = 0.06 meter
Hence, first option is wrong.
1 centimeter = 10 millimeter
6 × 1 centimeter = 6 × 10 millimeter
6 centimeter = 60 millimeter
Thus, third option is correct.
Answer:
Energy remain conserved while converting its form from one to another
Explanation:
As per the conservation of energy, energy always changes its form from one form to another and it is neither destroyed nor created. The total amount of energy always remains the same.
There are several forms of energy such as thermal energy, electrical energy, nuclear energy, electromagnetic energy, etc.
For example –
During any chemical reaction, form of one chemical changes into another. In this process some amount of chemical energy remains conserved while the deficit in total starting energy is released as heat and light energy
