Two square coils (1 and 2) of different size but with the same number of turns and carrying the same current are placed in diffe

rent magnetic fields but experience the same maximum torque. If each side of coil 1 is 4.80 cm and it rotates in a 0.18-T field, determine the length of each side of coil 2 if it rotates in a magnetic field of 0.42 T.

When do surface waves reach land​
Alex_Xolod [135]

Answer:

Surface waves are the kind of waves that occur on the surface of the ocean. The reason behind their occurrence is the geological effects, usually in the form of winds in near geographical regions or in that region.

These waves reach the land when the geological winds give a push to the waves and they travel miles and finally hit the land. These waves range in sizes, for small sizes to the the size of tsunami.

The earth has a vertical electric field at the surface, pointing down, that averages 100 N/C. This field is maintained by variou
Kipish [7]

Answer:

The excess charge on earth's surface was calculated to be 4.56 × 10⁵ C

Explanation:

Using the formula for an electric field;

E = kQ/r²

k = 1/(4πε₀) = 8.99 × 10⁹ Nm²/C²

E = 100N/C

r = radius of the earth = 6400 km = 6400000m

Q = Er²/k = 100 × (6400000)²/(8.99 × 10⁹)

Q = 455617.4 C = 4.56 × 10⁵ C

Hope this helps!!!

A violin with string length 32 cm and string density 1.5 g/cm resonates in its fundamental with the first overtone of a 2.0-m or
love history [14]

Answer:

T=1022.42 N

Explanation:

Given that

l = 32 cm ,μ = 1.5 g/cm

L =2 m  ,V= 344 m/s

The pipe is closed so n= 3 ,for first over tone

f=\dfrac{nV}{4L}

f=\dfrac{3\times 344}{4\times 2}

f= 129 Hz

The tension in the string given as

T = f²(4l²) μ

Now by putting the values

T = f²(4l²) μ

T = 129² x (4 x 0.32²)  x 1.5 x  10⁻³ x 100

T=1022.42 N
