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

1. You are designing a new solenoid and experimenting with material for each turn. The particular turn you are working with is a
svetoff [14.1K]

Answer:

Explanation:

1 ) Magnetic field due to a circular coil carrying current

= μ₀I / 2r

I is current , r is radius of the wire , μ₀ = 4π x 10⁻⁷

= 4π x 10⁻⁷ x 15 / (2 x 3.5 x 10⁻²)

= 26.9 x 10⁻⁵ T

2 )

Negative z direction .

The direction of magnetic field due to a circular coil having current is known  

with the help of screw rule or right hand thumb rule.

3 )

If we decrease the radius the magnetic field will:__increase _____.

A. Increase.

Magnetic field due to a circular coil carrying current

B = μ₀I / 2 r

Here r is radius of the coil . If radius decreases magnetic field increases.

So magnetic field will increase.

Sergio039 [100]

Answer:

Explanation:

<u>The question is asked in portuguese</u>

<u>Hence, it will be answered in portuguese</u>

1kg = 1000g

e

1 g = 1000mg

então

1 kg = 1 x (1000 x 1000)

1 kg = 1x 1.000.000

1 kg = 1.000.000mg

assim

 1 comprimido -------------> 0,025 mg

 x  comprimido ------------> 1.000.000 mg   ( só cruzar)

0,025(x) = 1(1.000.000)

0,025x = 1.000.000

x = 1.000.000/0,025

x = 40.000.000

<h3>1kg são feitos 40.000.000( Quarenta milhões de comprimidos)</h3>

What best explains the speed of sound in different states of matter? Sound travels fastest in ice because energy is easier to tr
vagabundo [1.1K]

The speed of sound depends on any form of matter or medium in which sound travels through it and depends on the amount of molecular collisions. Sound travels slowest in gas in the form of steam because the sound has to move around the gas molecules that are far apart making it harder for the energy of vibrations hit the particles and make sound.

Moreover, sound travelling through solids like ice is much faster because the particles are closer together so the sound waves do not have to travel that far making the number of collisions greater and sound spread more easily.
