Does the moon have water?

Answers

Answer 1

Explanation:

after rereading: Yes, there is a term for water on the moon and it's called lunar water, pretty straightforward. you can check out moon.nasa.gov, or literally look this up in the magical (g-engine) and it'll gove you a few articles.

______________________

oh my, sorry, i thought the question asked if the moon moved water, in which case: I wouldn't say that the moon actually MOVES the water, but yes, its gravitational force is strong enough to affect tides on Earth. (i could've sworn that's what I saw but whatever, sorry!)

Answer 2
It does not have normal water but it has lunar water

This is when water vapor is decomposed by sunlight. Leaving hydrogen and oxygen

A box shaped wooden stove has dimensions of 0.75 m *1.2 m*0.4 m. An emissity of 0.85 and surface temperature of 205 degrees Celsius. Calculate it's rate of radiation into surrounding space

Answers

The rate of radiation into surrounding space of the box shaped wooden stove at a temperature of 205 degrees Celsius is 8,453.82 J/s.

Rate of radiation of the wooden stove

The rate of radiation of the wooden stove is calculated as follows;

P =  εAσT4

Where:  

ε is emissivity of the SurfaceA is surface Areaσ is Stefan-Boltzmann Constant, 5.67 x 10⁻⁸ W/m²K⁴T is temperature in Kelvin, 205 ⁰C = 205 + 273 = 478 KSurface area of the box

A = 2(Lw + Lh + Wh)

A = 2(0.75 x 1.2  +   0.75 x 0.4   + 1.2 x 0.4)

A = 3.36 m²

P = 0.85 x 3.36 x (5.67 x 10⁻⁸) x (478)⁴

P = 8,453.82 J/s

Thus, the rate of radiation into surrounding space of the box shaped wooden stove at a temperature of 205 degrees Celsius is 8,453.82 J/s.

If the error in the angle is 0.50, the error in sin 90o is​

Answers

At the given erro in angle, the error in the measurement of sin 90 degrees would be 0.001.

Percentage error

The percentage error of any measurement is obtained from the ratio of the error to the actual measurement.

The error of sin 90 degrees is calculated as follows;

sin 90 = 1

error in measurement = sin(90 - 0.5)

error in measurement = sin(89.5) = 0.999

Error in sin 90 degrees

Error in sin 90 degrees = 1 - 0.999

Error in sin 90 degrees = 0.001

A series RLC circuit attached to a 120 V/60 Hz power line draws 2.80 A of current with a power factor of 0.830. What is the value of the resistor?

Answers

The value of the resistance of the series RLC circuit attached to a 120 V/60 Hz power line is 35.57 ohms.

What is power factor of RLC series circuit?

The power factor of RLC series circuit is determined from the ratio of resistance to the total impedance of the circuit.

Pf = R/Z

0.83 = R/Z

where;

R is the resistance of the circuitZ is the impedance of the circuit

Z = V/I

0.83 = R/(V / I)

0.83 = (RI) / (V)

RI = 0.83V

R = 0.83V/I

R = (0.83 x 120) / (2.8)

R = 35.57 ohms

Suppose two cars collide with each other

How can you minimize the danger to the passengers of the colliding cars?

Use the conservation of momentum to answer the question ​

Answers

We can minimize the danger to the passengers of the colliding cars by slowing down the car, by use airbag and other safety measures.

What is collision?

The abrupt, violent coming together in direct contact of two bodies is known as the collision.a falling object and a floor are examples of collision.

When the distance between two ships decreases while the bearings remain constant, a collision occurs.

If you can't discover an exit route and are almost certain to collide with anybody, you must slow down considerably. Any decrease in speed will lessen the harm to you, your vehicle, and your riders.

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

By the law of conservation of momentum, we understand the momentum get conserved. So we can find the collision velocity and reduces the chances of collision.

An electric space heater is connected across a 120 V outlet the heater dissipates 1320 W of power in the form of electromagnetic radiation and heat calculate the resistance of the heater

Answers

The resistance of the electric space heater dissipating the given amount of power is 10.9Ω.

Ohm's law

Ohm's law states that "the voltage across the cross-section of a conductor is directly proportional to the current passing through it.

It is expressed as;

V = I × R

Where V is voltage, I is current and R is resistance.

Also, electrical power is the product of current and voltage.

P = I × V meaning I = P/V

Hence,

V = (P/V) × R

R = V² / P

Given the data in the question;

Voltage V = 120VPower P = 1320WResistance of the heater R = ?

To determine the resistance of the heater, we substitute our given values into the derived expression above.

R = V² / P

R = (120V)² / 1320W

R = 14400V² / 1320W

R = 10.9Ω

The density of the unknown liquid is 650.67 kg/m³

Determine the density of the unknown liquid

First step : determine the mass in air

The Tension in air = mg

therefore Mass in air ( m ) = Tension in air / g

                                           = 3.78 kg

Considering Tension in water

T = 29.6 N

29.6 = 4/3 * πR³ * ( р - б ) g   ----- ( 1 )

where : р = mass density, б = water density

Considering Tension in other liquid

T = 19.1 N

19.1 = 4/3 * πR³ * ( р - б' ) g  ------ ( 2 )

Final step : Determine the density of the unknown liquid

Divide equation ( 1 ) by equation ( 2 )

1.54 = ( р - б ) / ( р - б' )

0.54 р + б = 1.54 * б'
