Answer:
P = 0.25 W
Explanation:
Given that,
The emf of the battry, E = 2 V
The resistance of a bulb, R = 16 ohms
We need to find the power delivered to the bulb. We know that, the formula for the power delivered is given by :
So, 0.25 W power is delivered to the bulb.
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.
Answer:
clockwise direction
Explanation:
Direction of induced current is found with the help of Lenz's law . According to this law , the direction of induced current is such that it tries to neutralize or oppose the reason which creates this current .
In the given case , magnetic field is towards the viewer of the screen and it is increasing , so the induced current will have to create magnetic field in opposite to it . It means magnetic field will be created towards the screen into it . So the current will be induced in clockwise direction . This current will create magnetic field into the screen which will oppose increasing magnetic field out of screen .
Answer: The wavelength is 3.33 km, the unit is km.
Explanation:
1) Data:
a) λ = ?
b) v = 10 km/s
c) f = 3 Hz = 3 s⁻¹
2) Formula:
wave equation: v = f × λ
3) Solution:
a) Solve for λ
λ = v / f
λ = (10 km/s ) / 3 s⁻¹
λ = 3.33 km
The wavelength is 3.33 km, the unit is km.
