Answer:
496.57492 kg/m³
Explanation:
= Atmospheric pressure = 101300 Pa
= Density of water = 1000 kg/m^3
= Height of water = 21.8 cm
= Height of fluid = 30 cm
g = Acceleration due to gravity = 9.81 m/s²
= Density of the unknown fluid
Absolute pressure at the bottom
The density of the unknown fluid is 496.57492 kg/m³
Answer:
12 cm
Explanation:
We shall use Lens makers formula here which is as follows
Put μ = 1.5 , R₁ = 10 cm ,R₂ = - 15 cm ( according to sign convention )
= .5 x ( 15 + 10 ) / 15 x 10
= 
F = 12 cm
Forces are considered balanced when all of the combined forces lead to no change in the motion of the object. For example, when a book is sitting on a table, the force of gravity is pushing downward and the normal force is pushing upward with exactly the same amount of force. Since they are equal and opposite forces, the book does not move.
Unbalanced forces exist when there are unequal forces acting upon the object, which leads to a change in the state of motion. Unbalanced forces can lead to a change in direction, a change in speed, or both a change in direction and in speed.
Answer:
<em>7.2 N</em>
Explanation:
length of wire L = 240 m
current I = 500 A
field strength B = 3 x 10^-5 T
magnetic force on a current carrying conductor F is given as
F = BILsin∅
The wires are perpendicular with field therefore sin∅ = sin 90° = 1
therefore,
F = BIL = 3 x 10^-5 X 500 X 240 = 3.6 N
<em>If the wire exists between this two transmission lines, then total magnetic force on the wire = 2 x 3.6 = 7.2 N</em>
Answer:
Pressure = 14.71N/m²
Explanation:
Given the following data;
Force = 375N
Area = 25.5m²
To find the pressure;
Pressure = force/area
Pressure = 375/25.5
Pressure = 14.71N/m²
Therefore, the amount of pressure that is being exerted by blood cells is 14.71 Newton per meter square.
