Answer:
The spillage of water
<em>PRECAUTION</em><em>:</em> Keep eureka can away from table edges and collect the displaced water in a measuring cylinder
Answer:
The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects.
Explanation:
Answer:
3.4 x 10^-4 T
Explanation:
A = 1.5 x 10^-3 m^2
N = 50
R = 180 ohm
q = 9.3 x 106-5 c
Let B be the magnetic field.
Initially the normal of coil is parallel to the magnetic field so the magnetic flux is maximum and then it is rotated by 90 degree, it means the normal of the coil makes an angle 90 degree with the magnetic field so the flux is zero .
Let e be the induced emf and i be the induced current
e = rate of change of magnetic flux
e = dФ / dt
i / R = B x A / t
i x t / ( A x R) = B
B = q / ( A x R)
B = (9.3 x 10^-5) / (1.5 x 10^-3 x 180) = 3.4 x 10^-4 T
Answer:
Resistance, R = 13 ohms
Explanation:
The Ohm's law gives the direct relationship between the voltage, current and the resistance of the device. The relation is as follows :
Where
I is the current
r is the resistance
The value of resistance is given by :
According to given data,
Voltage of the circuit, V = 130 V
Current rating of the circuit, I = 10 A
Resistance of the device,
R = 13 ohms
So, the resistance of the device is 13 ohms. Hence, this is the required solution.
Most countries besides the USA use the metric system also known as S.I (system internationale) as a system of measurement...
