DOS MOVILES PARTEN A LAS 12:00 AL MISMO TIEMPO HACIA EL NORTE DEL PAIS .¿ QUE DISTANCIA LOS SEPARA A LAS 13 HORAS SUPONIENDO QUE SUS VELOCIDADES SON 20 M/S Y 50 K/H ?
Answer:
22km
Explanation:
Las velocidades de los móviles nos van a definir cuánta distancia recorren por unidad de tiempo. Para resolver este problema debemos hallar la distancia recorrida en una hora por cada vehículo (Porque de las 12 horas a las 13 solo hay una hora)
Un móvil está recorriendo 50km/h. En una hora recorrerá: 50km
El otro móvil recorre 20m/s. En km/h:
20m/s * (3600s / h) = 72000m/h * (1km / 1000m) = 72km/h. El móvil recorrerá, en una hora, 72km
1h = 3600s; 1km = 1000m
La distancia que los separa es de:
72km - 50km =
22km

An ambulance took 2 hours to cover a distance of 10 kilometers. Find its speed.
Answer:
5km/hour
Explanation:
2hours = 10km
/2 /2
1 hour = 5km
An ambulance took 2 hours to cover a distance of 10 kilometers. Find its speed.
Answer:-Given:-Distance = 10 kilometers.
Time = 2 hours.
To Find:-Its speed.
Solution:-We know,
[tex] { \boxed{\bf{\rm \red {Speed \: = \: Distance \: × \: Time}}}} [/tex]
Speed = 10 kilometers × 2 hours
Speed = 20 km/hr
Its speed is 20 km/hr. [Answer]What is the freezing point of a solution that has 5.0 moles of Nal in 1250 g of water? (K = 1.86°C/m; molar

Para saber si se lleva a cabo una reacción donde un metal desplaza a otro metal de su sal u otro compuesto, es preciso:
Answer:
Explanation:
¡Hola!
En este caso, dado que las reacciones de desplazamiento simple se llevan a cabo cuando un metal desplaza a otro metal de su sal u otro compuesto, es preciso tener en cuenta la serie de reactividad de los metales que se muestra en el archivo adjunto.
Así, es mandatorio que el metal con el que la sal original reacciona, sea más reactivo que el catión de la misma, de modo contrario, la reacción tendría lugar. Por ejemplo, si el sodio reacciona con cloruro de zinc, al este primero estar más arriba en la serie, quiere decir que es capaz de desplazar el zinc en el cloruro original y así se formaría zinc metálico y cloruro de sodio.

chemical fertilizers rich in potassium
Explanation:
Fertilizers are chemically synthesized plant nutrients.
Nitrogen (N), Phosphorus (P) and Potassium (K) are macronutrients and are required in large amounts by plants. So, farmers use fertilizers in order to supply these nutrients. NPK 15:15:15 , NPK 20:20:20, NPK 15:30:15 are examples of fertilizers used to supply N, P, K to crops.
Explanation:
1.Potassium Nitrate(KNO3)
2.Potassium Sulphate(K2SO4)
They provide potassium to plants for making their roots and shoots healthy.
Calculate the molarity of 0.060 moles of sodium bicarbonate (NaHCO3) in 1500. mL of solution.
Answer: 0.040 mol/l
Explanation: Molarity c = n/V (Concentration)
c = 0.060 mol / 1,5 l = 0,040 mol/l

What equation is used to calculate atomic mass?
WARNING!!!! NO LINKS OR YOU WILL BE REPORTED!!!!
Answer:
Average atomic mass = f1M1 + f2M2 +… + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
What is the volume of 16.0 g of SO2 (g) at STP?
Answer:
Explanation:
At STP 1 mole of an ideal gas = 22.4 L.
Assuming SO2 (sulfur dioxide) acts as an ideal as, we have 16 g SO2 x 1 mol/64 g = 0.25 moles SO2
0.25 moles x 22.4 L/mole = 5.6 liters
How many kilojoules of heat must be transferred to a 480-g aluminum pizza pan to raise its temperature from 22°C to 234°C? The specific heat of aluminum in this temperature range is 0.96 J/g.°С. Show your work.
Answer:
97.7 kJ
Explanation:
We'll use the formula for specifc heat: Q=mcΔT
Q= heat/energy (Joules), m= mass (grams), c= specific heat (different for each substance and is usually given)
ΔT= final temperature - initial temperature
Let's check our given units and see if they're the correct, here they all are. Let's plug in what we know.
Q=mcΔT
Q=(480)(0.96)(234 - 22)
Q=(480)(0.96)(212)
Q= 97,690 J
Before we submit an answer, let's check out units. We have our answer in Joules, but we want it it kilojoules, so we'll convert it knowing that:
1000 Joules = 1 kilojoule
97,690J x [tex]\frac{1 kJ}{1000J}[/tex] = 97.7kJ

justin noticed several cracks in the sidewalk. Weeds are growing through them, cause the crack to expand. What process is this?
Answer:
Explanation:
Weeds and Small Plant Roots Exploit Existing Concrete Cracks
Instead, the plant's roots take advantage of existing microscopic cracks. New cell growth takes place at the tips of plant roots. ... Eventually, molecule by molecule, the plant's growth can force its way into the slab and create a surface crack.
Explain why the difference between the wet bulb temperature and the dry bulb temperature is always 0C when the relative humidity is 100%??
HELPPP!
Answer:
The dry bulb temperature is the ambient air temperature that is measured by regular thermometers, while the wet bulb temperature is measured by thermometers that are wrapped in wicks. The greater the wet bulb depression, the greater the felt effect is on the discharge air temperature.

to determine what the gemstone aquamarine might look like.
Determine what the gemstone aquamarine might look like?
Answer:
[tex] \huge\blue{ \mid{ \underline{ \overline{ \tt ♡ AQUAMARINE ♡ }} \mid}}[/tex]
=> The colour of this stone is usually a pale greenish blue, owing to the presence of iron impurities. Stones that are treated with heat look more blue than green. On the Mohs scale of hardness, aquamarine ranges between 7.5 and 8 making it a relatively hard gemstone.
=> The best way to identify a real aquamarine stone is by looking at its colour. In its natural form, they have a pale blue colour, which is similar to seawater. They may have a slight green or yellow tint as well. Naturally occurring gems have excellent clarity and transparency.
=> The hardness of the stone is another feature you can use to identify the stone. Aquamarine stones are hard and they don’t get scratches easily. However, they can easily scratch glass and other such surfaces. So, if you find visible scratches on the stone, rethink your decision to buy it.
=> Most faceted aquamarine stones are clean to the eye and clear of any inclusions. However, translucent and opaque aquamarine is also available. These are usually fashioned into cabochons or beads. In some cases, inclusions may appear as parallel tubes. Such stones can be crafted to show a cat’s eye. Stones with cat’s eye and star effect are rare and highly priced.
