A bulb is rated as 25Watt -250 Volt. On connecting this bulb to a mains of 250 volts, what will be the value of current (I) flow

ing in it, and how much resistance (R) will the bulb provide to this flow of current?

Answer:

I=0.1 R=2500

Explanation:

Resistance

$R=\frac{V^{2} x}{P} \\=\frac{250^{2} }{25} \\=2500$

Current

$I=\frac{250}{2500} \\=0.1$

You pull a solid nickel ball with a density of 8.91 g/cm3 and a radius of 1.40 cm upward through a fluid at a constant speed of

Sunny_sXe [5.5K]

Answer:

$P = 1.090\,N$

Explanation:

The constant speed means that ball is not experimenting acceleration. This elements is modelled by using the following equation of equilibrium:

$\Sigma F = P - W + F_{D}$

$\Sigma F = P - \rho \cdot V \cdot g + c\cdot v = 0$

Now, the exerted force is:

$P = \rho \cdot V \cdot g - c\cdot v$

The volume of a sphere is:

$V = \frac{4\cdot \pi}{3}\cdot R^{3}$

$V = \frac{4\cdot \pi}{3}\cdot (0.014\,m)^{3}$

$V = 1.149\times 10^{-5}\,m^{3}$

Lastly, the force is calculated:

$P = (8910\,\frac{kg}{m^{3}} )\cdot (1.149\cdot 10^{-5}\,m^{3})\cdot (9.81\,\frac{m}{s^{2}} )+(0.950\,\frac{kg}{s})\cdot (0.09\,\frac{m}{s} )$

$P = 1.090\,N$

Periodic waves spread out over the surface of a lake where two women, Jenny and Melissa, are fishing in separate boats 46 meters

Tatiana [17]

Answer:

The wavelength of the water is $\lambda = 10.22 m$

Explanation:

From the question awe are told that

The distance between the two boats are 46 m

Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as

Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)

= 4.5

Now the wavelength of the water is $\lambda = \frac{Distance }{Number \ of \ division }$

$= \frac{46}{4.5} =10.22m$
