How far (in meters) will you travel in 3 minutes running at a rate of 6 m/s?

trasher [3.6K]

The formula for distance is speed times time.

So 3 times 6 would be 18 m/s

The plate area is doubled, and the plate separation is reduced to half its initial separation. What is the new charge on the neg

Norma-Jean [14]

Answer:

Q = 4 Q₀

Explanation:

This is an exercise on capacitors, where the capacitance is

C = $\epsilon_{o} \ \frac{A}{d}$

if we apply the given conditions

C = \epsilon_{o} \ \frac{2A}{0.5d}

C = 4 \epsilon_{o} \ \frac{A}{d}

let's call the capacitance Co with the initial values

C₀ = \epsilon_{o} \ \frac{A}{d}

C = 4 C₀

The charge on each plate of a capacitor is

Q = C ΔV

If the potential difference is maintained, the new charge is

Q = 4 C₀ ΔV

let's call

Q₀ = C₀ ΔV

we substitute

Q = 4 Q₀

What effect do sound waves have on air particles

valkas [14]

Answer:

Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.

A spacecraft at rest has moment of inertia of 100 kg-m^2 about an axis of interest. If a 1 newton thruster with a 1 meter moment

snow_lady [41]

Answer:

18 radians

Explanation:

The computation is shown below:

As we know that

Torque = Force × Moment arm

= 1N × 1M

= 1N-M

Torque = $I\alpha$

$\alpha = \frac{torque}{I}\\\\= \frac{1}{100}\\\\= 0.01 rad/s^2$

Now

$\theta = w_ot + \frac{1}{2} \alpha t^2\\\\w_o = 0\\\\\theta = 0 \times 60 + \frac{1}{2} \times 0.01 \times 60^2\\\\= 18\ radians$

Here t = 1 minutes = 60 seconds
