Answer:
6.54 × 10⁻⁵ Pa-s
Explanation:
Since the shear force, F = μAu/y where μ = viscosity of fluid between plates, A = area of plates, u = velocity of fluid = 0.6 m/s and y = separation of plates = 0.02 mm = 2 × 10⁻⁵ m
Since F = μAu/y
F/A = μu/y where F/A = force per unit area
Since we are given force per unit area, F/A = 1.962 N per unit area = 1.962 N/m²
So, μ = F/A ÷ u/y
substituting the values of the variables into the equation, we have
μ = F/A ÷ u/y
μ = 1.962 N/m² ÷ 0.6 m/s/2 × 10⁻⁵ m
μ = 1.962 N/m² ÷ 0.3 × 10⁵ /s
μ = 6.54 × 10⁻⁵ Ns/m²
μ = 6.54 × 10⁻⁵ Pa-s
Answer: An electric circuit is a representation of how current moves from the source of the current( example a battery or a cell) through resistors and other devices before entering the source.
Explanation:
The two important types of electrical circuit includes:
--> open circuit and
--> closed circuit.
A circuit is said to be open when the electrical source, such as the battery or the cell, is not connected to any external conductor (or resistance). In this situation, any voltmeter connected across the terminal of the cell measures the total driving force of the cell.
In this type of circuit, current cannot flow from one end of power source to the other due to interruptions.
A circuit is said to be closed if the source of electricity is connected to an external conductor through which current is passed.
In a closed circuit, there is complete electrical connection which allows current to flow or circulate. Here, part of the total driving force of the source is used to drive current through the external resistance and the difference is used to overcome the internal resistance of the battery.
Answer:
Radius,
Explanation:
It is given that,
Magnetic field, B = 0.275 T
Kinetic energy of the electron,
Kinetic energy is given by :
v = 1037749.04 m/s
The centripetal force is balanced by the magnetic force as :
So, the radius of the circular path is . Hence, this is the required solution.
Answer:
f= -9cm, v= -6cm. The focal length of a concave mirror can be estimated by focusing a distant object on a screen. Parallel rays from a distant object converge at the focal plane of the mirror. The distance between the mirror and the screen is the estimated focal length of the concave mirror.
