A closely wound rectangular coil of 75.0 turns has dimensions of 22.0 cm by 45.0 cm . The plane of the coil is rotated from a po

pentagon [3]

Answer:51.52 V

Explanation:

Given

N=75 turns

$Area=22\times 45 cm^2$

$\theta =36^{\circ}$

$Emf induced =-N\frac{\mathrm{d}\phi }{\mathrm{d} t}$

$Emf=-75A\frac{B_2-B_1}{t}$

$Emf=-75\times 22\times 45\times 10^{-4}\frac{1(1-cos(90-36))}{6\times 10^{-2}}$

Emf=51.52 V

A penny falls from a windowsill which is 25.0 m above the sidewalk. How much time does a passerby on the sidewalk below have to

Yanka [14]

You need to know the formula:

25 = 1/2 * g * t^2

t = √(50/g) = 2.258 s, where I use g = 9.8 m/s^2

If I release a golf ball at a height of 31 cm and a length of 31 cm the mass is equal to 45.93 g what is theKinetic energy

prohojiy [21]

When a ball is at a particular height it possess potential energy which is given as,

$U=\text{mgh}$

The potential energy is converted into kinetic energy of the ball. According to conservation of energy,

$K=U$

which can be further given as,

$K=\text{mgh}$

Substitute the known values,

$\begin{gathered} K=(45.93\text{ g)(}\frac{1\text{ kg}}{1000\text{ g}})(9.8m/s^2)(31\text{ cm)(}\frac{1\text{ m}}{100\text{ cm}})(\frac{1\text{ J}}{1kgm^2s^{-2}^{}}) \\ =0.140\text{ J} \end{gathered}$

Thus, the kinetic energy of the ball is 0.140 J.
