"Watch" . . . atmospheric conditions exist that could
produce tornados, but none have been seen yet.

"Warning" . . . tornados have formed and have been seen.

It takes 50 seconds for Tyler to do 450 Joules of work. How much power did Tyler use?

Tomtit [17]

Answer:

<h2>The answer is 9 W</h2>

Explanation:

The power used by an object can be found by using the formula

$p = \frac{w}{t} \\$

w is the workdone

t is time taken

From the question we have

$p = \frac{450}{50} = \frac{45}{5} \\$

We have the final answer as

Hope this helps you

PLZ HELP ME GUYS!!!! Using appropriate terminology, contrast transverse and longitudinal waves. Hint: How are they different? Yo

kobusy [5.1K]

<h3>Longitudinal Waves:</h3>

Longitudinal waves are waves in which particles moves in the direction parallel to the direction of wave.
Longitudinal wave are one directional waves.
Sound waves and tension force applied on spring are examples of longitudinal waves.

<h3>Transverse Waves:</h3>

Transverse waves in which particles move perpendicular to the direction of wave propagation.
Transverse wave are two directional waves.
Ripples formed on water and all electromagnetic waves are examples of transverse waves.

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t

NemiM [27]

Answer:

their final velocity is 0.091 m/s

Explanation:

Given;

mass of the first train, m₁ = 138,000 kg

mass of the second train, m₂ = 123,000 kg

initial velocity of the first train, u₁ = 0.288 m/s

initial velocity of the seocnd train, u₂ = -0.131 m/s (opposite direction to the first)

Let their common final velocity after been coupled = v

Apply the principle of conservation of linear momentum;

m₁u₁ + m₂u₂ = v(m₁ + m₂)

(138,000 x 0.288) + (-0.131 x 123,000) = v(138,000 + 123,000)

39,744 - 16,113 = v(261,000)

23,631 = v(261,000)

v = 23,631 / 261,000

v = 0.091 m/s

Therefore, their final velocity is 0.091 m/s

what is a possible unit for the product VI, where V is the potential difference across a resistor and I is the current through t

liq [111]

Recall this equation for a device in a direct current circuit:
P = IV
P is the power dissipated by the device, I is the current through the device, and V is the voltage drop of the device.

If we choose to use the ampere as the unit of current and the volt as the unit of voltage, then the product of the current and the voltage will give the power with watts as the unit.
