batman recharges his bat taser with 2.5mj of energy in 15 minutes how much power does it draw from the mains

Physics
1 answer:
aalyn [17]3 years ago
3 0

Power = (energy) / (time)

15 minutes = 900 seconds

Power = (2.5mJ) / (900 sec)

<em>Power = 0.00278 mWatts</em>

If your 'm' means 'Mega...', then power = 2,777.8 watts ... about the same as a hefty restaurant toaster, or home microwave oven when it's cooking.

State the relative position for the sun and earth during the lunar eclipse (ASAP)
Mademuasel [1]

Answer:

Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.

There is an old physics joke involving cows, and you will need to use its punchline to solve this problem
aleksandr82 [10.1K]

Answer:

The angle of deflection will be "1.07 × 10⁻⁷°".

Explanation:

The given values are:

Mass of a cow,

m = 1100 kg

Mass of bob,

mb = 1 kg

The total distance between a cow and bob will be,

d = 2 m

Let,

The tension be "t".

The angle with the verticles be "\theta".

Now,

Vertically equating forces

⇒  T\times Cos \theta =mb\times g ...(equation 1)

Horizontally equating forces

⇒  T\times Sin \theta = G\times M\times \frac{mb}{d^2} ...(equation 2)

From equation 1 and equation 2, we get

⇒  tan \thata=\frac{G\times M}{g\times d^2}

O putting the estimated values, will be

⇒  \theta = tan(\frac{6.674\times 10^{-11}\times 1100}{9.8\times 2^2} )

⇒  \theta = 1.07\times 10^{-7}^{\circ}

Mike understands the formula for temperature conversion, but is having difficulty imagining what various temperatures feel like.
Alisiya [41]

A good example that will help to to tell mike what 37°c feels like is body temperature.

<h3>What is room temprrature?</h3>

The average room temperature is typically around 20°C, or 68 degrees Fahrenheit.

<h3>What is body temperature?</h3>

The average body temperature is 98.6 Fahrenheit or 37 degrees Celsius.

Thus, a good example that will help to to tell mike what 37°c feels like is body temperature.

A resistor R1 is wired to a battery, then resistor R2 is added in series.
Reika [66]

Answer:

a) The voltage on resistor R1 is less than before. Letter B.

b) The current through R1 is less than before. Letter B.

c) The resistance of the circuit went up by adding R2 in series. Letter A.

Explanation:

a) The new resistor R2 was added in series, that means the same current goes through both resistors (R1 and R2) and that the sum of the individual voltage drop of those resistors should be the same as the voltage of the source. Before there was only resistor R1 connected to the source, so all the voltage of the source was being delivered to that component, but now it is divided between R1 and R2. So the voltage on R1 is less than previously. Letter B.

b) A battery works as a voltage source, so assuming it's charged, it delivers a value of voltage to the circuit, while the current flow through it is defined by the equivalent resistance across the terminals. Since the new resistor was added in series the total resistance of the circuit went up and the current delivered by the battery went down. Letter B.

c) Since the equivalent resistance for a series connection is the sum of the resistors, R12 = R1 + R2, the resistence went up. Letter A.
