Assoli18 [71]3 years ago
7 0

Answer:

313, 0.60 s

Explanation:

wavelength

= speed/frequency

= 340/520

= 0.6538 m

Number of wavelengths

= 205/0.6538

= <u>313</u> (whole number)

Time delay

= distance/speed

= 204/340

= <u>0.60 s</u>

A copper rod 0.570 � long and with a mass 0.05900 �� is suspended from two thin wire. At right angle to the rod is a uniform mag
finlep [7]

Answer:

a) Left to right

b) 1.51 A

Explanation:

a)

The gravitational force on the rod due to its mass is in downward direction. hence to levitate the rod, the magnetic force on the rod must be in upward direction.

The magnetic field is inward to page and magnetic force must be upward. Using right hand rule, the current must be flowing from left to right.

Left to right

b)

L = length of the copper rod = 0.570 m

m = mass of the rod = 0.059 kg

B = magnitude of magnetic field in the region = 0.670 T

θ = Angle between the magnetic field and rod = 90

i = current flowing throw the rod = ?

The magnetic force on the rod balances the gravitational force on the rod. hence

Magnetic force = gravitational force

mg = i B L Sinθ

(0.059) (9.8) = i (0.670) (0.570) Sin90

i = 1.51 A

True or false: in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector
olganol [36]

It is False in applying the pythagorean theorem to vector addition, the resultant vector is given by the perpendicular vector

<h3>What is Pythagoras theorem ?</h3>

A useful technique for figuring out the outcome of adding two (and only two) vectors that form a right angle to one another is the Pythagorean theorem. The technique cannot be used to combine more than two vectors or to combine vectors that are not at a 90-degree angle.

  • The Pythagorean Theorem demonstrates how the side lengths of a right triangle can be calculated from the sum of the areas of three intersecting squares. This theorem is a very helpful tool that serves as the foundation for more intricate trigonometry ideas like the Pythagorean theorem's opposite.
