Para hacerlo a m/s un método muy práctico es sólo dividir entre 3.6, por cuestiones de conversiones, lo puedes comprobar.
212 km/hr /3.6 = 58 m/s
Comprobación :
V= d / t
V= 212 m / 18000 seg <---- nota que aquí los segundos son de las 3.1hrs

Answer:
Tadpoles are baby frogs. The tadpole looks like a frog with a tail and becomes a froglet around 12 weeks after hatching. The tadpole becomes an adult frog around 13 to 16 weeks after hatching.

Explanation:
Free fall means that an object is falling freely with no forces acting upon it except gravity, a defined constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling.
if v= 4.3 + 1.2% and I = 2.1A + 4.5% find the resistance and significant figures

is three times the height of Mt. Everest.
B
is almost as tall as Mt. Everest.
C
has been visited 44 times.
D
is wet, rocky and cold.
Answer: Is three times the height of Mt. Everest
Explanation:
Using the process of elimination we can rule out “D” Because its a volcano, C because it says we have visited mars 44 times not the volcano, B because in the passage is literally says “3 times the size of Mt. Everest”.

A ball is thrown straight up from the ground with an unknown velocity. It returns to the ground after 4.0 s. With what velocity did it leave the ground?
Answer:
It must return at the same velocity with which it was thrown or else there would be a preferred direction of motion leading to perpetual motion.
a = (v2 - v1) / t = (v2 - 0) / 2 = v2 / 2 for a falling object
v2 = 2 a = 2 sec * 9.8 m/sec^2 = 19.6 m/s
You can check with
H = V0 t - 1/2 g t^2 (V0 and g are in different directions)
H = 0
V0 = 1/2 g * 4 = 19.6 m/s
Use the velocity vs time graph to analyze the motion of the object.
Explanation:
the object has constant velocity for 2 seconds and it get a constant accelration (2ms-2)
explain why you cant see our reflection better in a piece of metal
Answer:
metal and glass are very smooth and reflect light back more directly this is called specular reflection if you look into a lake on a wide windless day you will be able to see your reflection because of the smooth surface of the water is producing the specular reflection rather than diffuse reflection
a large bottle contains a number of medicinal tablets each having a mass of 250mg the mass of all the tablets is 0.5kg calculate the number of tablets in the bottle
Considering the change of units and rule of three, the number of tablets in the bottle is 2,000.
First of all, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 0.5 kg. You can see that the measurements are in different units of measurement, so you must make a change of units so that they are in the same units.
So, knowing that 1 kg is equal to 1,000,000 mg, you can apply the following rule of three: if 1 kg is equal to 1,000,000 mg, 0.5 kg is equal to how many mg?
1 kg ⇒ 1,000,000 mg
0.5 kg ⇒ x mg
So: [tex]x=\frac{0.5 kgx1,000,000 mg}{1 kg}[/tex]
x= 500,000 mg
Then, you know that each medicinal tablet has a mass of 250 mg, while the mass of all tablets is 500,000 mg. Now that the values are in the same units, to calculate the number of medicinal tablets you must apply the following rule of three: if 1 tablet has a mass of 250 mg, how many tablets have a mass of 500,000 mg?
[tex]number of medicinal tablets=\frac{500,000 mgx1 tablet}{250 mg}[/tex]
number of medicinal tablets= 2,000
Finally, the number of tablets in the bottle is 2,000.

A delivery truck travels 18 blocks north, 10 blocks east, and 16 blacks south What is the
distance traveled and displacement? Assume all blocks are the same length
Force Unit
Answer:
Traveled north = 18 blocks
Traveled east = 10 blocks
Traveled south = 16 blocks
So total distance = (18+10+16) blocks = 44 blocks
as north and south are opposite
so traveled displacement from up to down is = (18-16) blocks = 2 blocks
and starting to east distance is 10 blocks
so using pythagoras theorem the displacement
= [tex]\sqrt{10^{2}+2^{2} }[/tex] blocks
= [tex]\sqrt{104}[/tex] blocks
= [tex]2\sqrt{26}[/tex] blocks
= 10.198 blocks (approx.)
ANS: distance=44 blocks, displacement=10.198 blocks (approx.)
Explanation:
Explain why the coin is able to float on top of the water in this glass.
Answer:
Surface tension is the result of water molecules pulling inward with a strong attractive force. This attractive force brings the molecules on the surface of the water close together and causes the surface of the water to be drawn toward the water molecules beneath the surface. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.

it is important to realize that an element’s line spectrum can include emissions at wavelengths throughout the electromagnetic spectrum including ultraviolet, visible, and infrared. according to the procedure in section 2, where will you be collecting data on hydrogen and helium’s line spectra?
Answer:
visible region
Explanation:
According to the procedure in section 2, in visible region the data collected on hydrogen and helium’s line spectra.
What is electromagnetic spectrum?Electromagnetic spectrum are the wave which is form of energy and includes the waves such as radio waves, gamma waves, visible light waves etc.
An element’s line spectrum can include emissions at wavelengths throughout the electromagnetic spectrum including ultraviolet, visible, and infrared.
Types of electromagnetic spectrum-
Radio waves-Radio waves are used to broadcast the signal and television signals.Microwaves-Microwaves are used in the mobile signals, Radar and in cooing the food.Infrared-Infrared transmit heat from difference sourced of fire.Visible light-This is the type of electromagnetic radiation, which is visible to the human eye.Ultraviolet-Ultraviolet electromagnetic radiation used in florescent tubes.X-rays- X-rays are used to see throughout the objects and the bodies.Gamma rays- Used in medical, to kill the cell causes cancer.
The hydrogen line spectra fall between wavelength, 410 nm to 656 nm. The helium line spectra fall between wavelength, 400 nm to 781 nm.This two fall in the visible region of line spectra.
