When clouds typically produce precipitation and why?

1 answer:

6 0

When the clouds get really heavy due to increased water vapor in the air so the lower the clouds get the more likely precipitation will occur.

Momentum ap physics 1

11111nata11111 [884]

Answer:

The correct option is;

B. Object X travels at -2 m/s and object Y travels at 4 m/s after the spring is no longer compressed

Explanation:

The given parameters are;

The mass of object Y = M

The mass of object X = 2·M

The initial velocity of object X and object Y = 0 m/s

Let A represent the velocity of object X after the spring is released and B represent the velocity of object Y after the spring is released, therefore, by the principle of the conservation of linear momentum, we have;

(M + 2·M) × 0 = M × B + 2·M × A

∴ (M + 2·M) × 0 = 0 = M × B + 2·M × A

M × B = -2·M × A

∴ B = -2·A

Therefore, the velocity of the object Y = -2 × The velocity of the object X

Whereby the velocity of the object X = -2, The velocity of the object Y = -2 × -2 = 4

Which gives, object X travels at -2 m/s and object Y travels at 4 m/s after the spring is no longer compressed.

A battery is the power source for what type of current

patriot [66]

Answer: DC Current

Explanation:

Battery is a source of constant potential difference and it will create a constant voltage across any conductor

due to this constant voltage difference the current in this conductor will remain constant

So here since the voltage across the conductor is constant so we can say that current in the conductor will remain constant and hence this is known as DC current.

While for variable current in direction and magnitude is to be obtained only when the conductor is connected with AC voltage source as we know that AC voltage is variable with magnitude and direction both

A battery is the power source for DC type of current. A battery is a source of constant potential difference that produces a constant current unlike in AC source where the voltage and hence the current changes its polarity continuously.Hence, the current produced by battery is direct current and not Alternating current.

Hope this helps........ Stay safe and have a Merry Christmas!!!!!! :D
