Answer:
16.6km/h
Explanation:
Speed is distance/time.
speed for 1st event = 1/0.4 = 2.5km/h
speed for 2nd event = 50/1.5 = 33.3 km/h
speed for 3rd event = 10/0.7 = 14.28 km/h
Average speed = 2.5 + 33.3 + 14.28 /3 = 50/3 = 16.6 km/h

HEYOO PEEPS 1. Ethan Rides his bike up a 20km hill in 2hrs. Ethan rides his bike down the 20km hill in .5 hrs. What is Ethan’s average speed?
Answers
Answer:
let Leo's speed = x mile/hr
so Ethan speed = (x + 6) miles per hour
Distance = Speed × Time
so distance traveled by Leo in 2 hours = x × 2 = 2x
and distance traveled by Ethan in 1.5 hours = 1.5( x + 6 ) = 1.5x + 9
since they meet on the path , After Ethan has ridden 1.5 hours and Leo has ridden 2 hours , so together the have traveled on complete path that is 65 miles.
⇒ distance traveled by leo in 2 hours + distance traveled by Ethan in 1.5 hours = 65
⇒ 2x + 1.5x + 9 = 65
⇒ 3.5x = 56
⇒ x = 16
Hence Leo's speed = x miles/hr = 16 miles/hour
and Ethan's speed = (x + 6) miles/hr = 16 +6 = 22 mile/hour

write an Argument for people of westfield identifying the reddish brown substance. Plz answer this is due tomorrow!!
Answers
Answer:
The reddish-brown substance is a different color than the fertilizer, which is white, and the substance that makes up the pipe, which is gray. This means that they cannot be the same substance because they do not have the same properties. The atomic models show that the reddish-brown substance is made up of different repeating groups of atoms than the fertilizer and the pipe substance. The difference in atoms caused the difference in properties.
Explanation:
lul
People of westfield identifying the reddish brown substance and that substance is rust i.e. iron oxide.
What is rust?Rust is a chemical compound which is formed by the oxidation reaction between iron and oxygen for the formation of iron oxide.
People of westfield observed the reddish brown color in the water, that is the rust compound which is obtained by the chemical reaction occur between the iron pipes and the compound present in the fertilizers that are present in water.
Hence, the reddish brown substance in rust.

How much energy does a wave with a frequency of 7.0 x 1012 Hz have
Answers
Answer:
4.64 × 10⁻²¹ J/s
Explanation:
[Only if the wave travels at the speed of light]
Because a wave presumed to be at light speed is a photon, E = hf.
If frequency is not given, E = hc/λ
c is the speed of light in meters per second. c = 299, 792, 458 m/s.
λ is the wavelength which is dependent.
h or plancks constant = 6.62607004 × 10⁻³² m² kg / s.
E is in units of J / s or jules ( m² kg ) per second.
If the wave has a frequency of 7.0 x 10¹² Hz or 7 THz (Tera-Hertz).
E = (6.62607004 × 10⁻³⁴) × (7.0 × 10¹²) =
46.38249028 × 10⁻²² =
4.638249028 × 10⁻²¹ J/s ≈
4.64 × 10⁻²¹ J/s

The poisonous gas hydrogen sulfide, H2S, can be neutralized with a base such as sodium hydroxide,
NaOH. The unbalanced equation for this reaction follows:
NaOH(aq) + H25(e) → Na2S(aq) + H2O(1)
A student who was asked to balance this equation wrote the following:
Na2OH(aq) + H2S(g) → Na2S(aq) + H2O(
Is this equation balanced? Is it correct? Explain why or why not, and supply the correct balanced
equation if necessary.
Answers
Answer:
It's not correct. For balancing, we need to put the coefficients in the molecule, not in the athom. Because if you do this, you're creating another molecule, instead of a balacing, for which the reaction may not happen - but anyway, it would be another reaction.
The correct balacing is:
2NaOH + 1H2S → 1Na2S + 2H2O
Explanation:
Look: Na2OH does not even exist. OH has only one free link, so he can't - in normal conditions - make another one with any athom. That's why we should write 2NaOH instead of Na2OH. The first means "2 mols of NaOH".

Answers
Answer:
The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.

Calculate the molar volume (volume of 1.0 mole) of an ideal gas at 1.0 atm and 25 °C?
Answers
Answer:
24.47 L
Explanation:
Using the general gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = 0.0821 Latm/molK
T = temperature (K)
According to the provided information in this question,
P = 1.0 atm
V = ?
n = 1 mol
T = 25°C = 25 + 273 = 298K
Using PV = nRT
V = nRT ÷ P
V = 1 × 0.0821 × 298 ÷ 1
V = 24.465 ÷ 1
V = 24.465
V = 24.47 L
