The moon is halfway through the waxing crescent phase. In approximately how many days will it be in the last-quarter phase?

Jlenok [28]

Let's say the Moon's complete cycle of phases is about 28 days (4 weeks) ... just so the arithmetic is easier. (Close enough. It's actually 29.53 days.)

If it's halfway through the waxing crescent, then it'll reach first quarter in 3 days or so.

From there, it'll take the next 7 days to become Full, and another 7 days to reach last quarter.

Total from half-waxing-crescent to last quarter . . . about 17 days.

Calculate the average net force.

MrRa [10]

Answer:

<h2>given</h2>

mass = 3950 kg

speed= 25m/ sec

time= 10.5 sec

force

<h2>Solution</h2>

<h3>☄️Formula of force </h3>

$\fbox{f = m.a}$

To find the force we need to find the Acceleration first.

accleration= change in Velocity/time

accleration= 25/10.5

accleration= 2.38 m/sec²

put the value of accleration in the formula of force

force = Mass . accleration

force = 3950 x 2.38

<h3>☄️force = 9,401 Newton</h3>

How does electromagnetic affect people in the world ?

tangare [24]

That depends on the wavelength of the electromagnetic radiation.

-- If the waves are long, then we use them for radio, TV, and cellphones.

-- If the waves are shorter than that, then we use them for GPS in the car.

-- If the waves are shorter than that, then we use them to heat meatloaf
in the microwave oven.

-- If the waves are shorter than that, then they warm us and they
make our plants grow ... like the ones we eat.

-- If the waves are shorter than that, then our eyes use them to see with.

-- If the waves are shorter than that, then they tan our skin.

-- If the waves are shorter than that, then they can cause cancer on
our skin.

-- If the waves are shorter than that, then they can cause cancer and
other diseases in places inside our body.

El tren Lima la Orolla va a una velocidad de 10 km/h y de pronto aplica el freno por un derrumbe en la via. Si demora 18 segundo

Naya [18.7K]

Answer:

Distancia = 50.04 metros

Explanation:

Dados los siguientes datos;

Velocidad = 10 km/h

Tiempo = 18 segundos

Para encontrar la distancia;

Conversión:

10 km/h = 10 * 1000/3600 = 2.78 m/s

Distancia = velocidad * tiempo

Distancia = 2.78 * 18

Distancia = 50.04 metros

Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.
