Answer:

d fan 2 becuase Fan 1 converts some energy into sound

Explanation:

Why is the awnser D you ask me?

Well its becuase sound is energy and to make sound you must use other energy. fan 1 uses some of its kinetic energy and converts it to sound and slows down becuase it waste kinetic energy for sound. on the other hand fan 2 converts all its electrical energy (of course it emits some infered light) into kinetic energy.

You are in the lab and are given two rods set up so that the top rod is directly above the bottom one. The two straight rods 50-
kompoz [17]

Answer:

Explanation:

The magnetic force due to lower rod must be equal to weight of upper rod for equilibrium .

magnetic field due to lower rod on upper rod

= ( μ₀ / 4π ) x(2i / r ) , i is current , r is distance between rod

= 10⁻⁷ x 2 x 15 / 1.5 x 10⁻³

= 20 x 10⁻⁴ T

force on the upper rod

= B i L , B is magnetic field , i is current in second rod and L is its length

= 20 x 10⁻⁴ x 15 x .50

= 150 x 10⁻⁴ N

= .015 N

This force can balance a wire having weight equal to .015 N .

= .00153 kg

= 1.53 g .

wire should weigh 1.53 g .

Please help. All the information is in the image.
kondaur [170]

The tiger's position at time <em>t</em> is given by

<em>x</em> (horizontal) = (4.5 m/s) <em>t</em>

<em>y</em> (vertical) = 7.5 m - 1/2 <em>gt</em> ²

Solve <em>y</em> = 0 for <em>t</em> to find the time it takes for the tiger to reach the ground :

0 = 7.5 m - 1/2 (9.8 m/s²) <em>t</em> ²

===>   <em>t</em> = √(2 (7.5 m) / (9.8 m/s²)) ≈ 1.2 s

Evaluate <em>x</em> at this time :

<em>x</em> = (4.5 m/s) (1.2 s) ≈ 5.6 m
