Answer:

34.3Hz

Explanation:

We know that

For a pipe open at one end, fundamental frequency (Fo)

is

Fo = v/4L

Where v= 340m/s

Fo = 340/4 x 2.48 = 34.3Hz

The 1.19 kg head of a hammer has a speed of 8.4 m/s just before it strikes a nail (Fig. 14-13) and is brought to rest. Estimate
KATRIN_1 [288]

Answer:

The temperature rise is 143.9\ K.

Explanation:

Given the mass of the hammer (m) is 1.19 kg.

And the speed of the hammer (v) is 8.4 m/s.

We need to find the temperature change of iron nail having 20 hammer blows.

First, we will find the kinetic energy of the each blow of hammer.

K.E=\frac{1}{2}mv^2

K.E=\frac{1}{2}\times 1.19\times 8.4^2=41.99\ J

For 20 such blows, the kinetic energy will be

20\times K.E=20\times 41.99=839.8\ J

Let us assume that the nail absorbs all the kinetic energy. So, this 839.8 J will be converted into heat energy (Q).

Now,

Q=839.8\ J

Also, we know that

Q=mc\Delta_T

Where,

m is the mass of the nail, which is 13\ g=\frac{13}{1000}=0.013\ kg

c is the specific heat capacity of iron, which is 449 J/kg.K

\Delta_T is the change in temperature.

Plug these value we get,

Q=mc\Delta_T\\839.8\ J=(0.013\ kg)(449\ J/kg.K)\times\Delta_T\\\Delta_T=\frac{839.8}{0.013\times 449}\\\\\Delta_T=143.9\ K

We can see the temperature rise is 143.9 K.

A 0.270 m radius, 510-turn coil is rotated one-fourth of a revolution in 4.17 ms, originally having its plane perpendicular to a
vlada-n [284]

Answer:

0.35701 T

Explanation:

B_i = Initial magnetic field

B_f = Final magnetic field

\phi = Magnetic flux

t = Time taken = 4.17 ms

N = Number of turns = 510

\epsilon = Induced emf = 10000 V

r = Radius = 0.27 m

A = Area = \pi r^2

Induced emf is given by

\epsilon=-N\frac{d\phi}{dt}\\\Rightarrow \epsilon=-N\frac{B_fAcos90-B_iAcos0}{dt}\\\Rightarrow \epsilon=N\frac{B_iA}{dt}\\\Rightarrow B_i=\frac{\epsilon dt}{NA}\\\Rightarrow B_i=\frac{10000 \times 4.17\times 10^{-3}}{510\times \pi 0.27^2}\\\Rightarrow B_i=0.35701\ T

The magnetic field strength needed is 0.35701 T
