Answer: A) as speed changes, wavelength changes and frequency remains constant
Explanation: edg test
The different versions of an element have different isotopes, like Copper-63 and Carbon-65. The average of these two is not 64, because there are more Carbon-63 in the world than Carbon-65, 69.17% Copper-63 and 30.83% Copper-65, to be exact. By multiplying the atomic mass per unit of each one times their respective abundance in the world turned into a decimal, and adding these two products together, you het the atomic mass overall, which is 63.55
Answer:
Olivine, with the formula (Mg,Fe)₂SiO₄
Explanation:
Olivine is a mineral with the formula (Mg,Fe)₂SiO₄. It is a magnesium iron silicate (or ferromagnesian mineral) that constitutes the largest part of the earth's upper mantle. The mantle is the second layer of the earth found in between the core (below) and the crust (on top). It accounts for about 84% of the earth's volume (as regards the layers of the earth).
Answer:
except ii and iii
Explanation:
The angle of reflection is the angle to the normal the white rays strikes the water surface and it is the incidence angle. Since the white light is moving from less dense medium to a denser medium or a medium with a higher refractive index; the angle of refraction will be less than 30 degrees. Total internal reflection cannot occur because the white light is traveling from a less dense medium to a denser medium.
When the speed of the car increases by 13.3 percent, the breaking distance increases by 13.3 percent as well.
<h3>
Increase in the distance of the car</h3>
The increase in the distance of the car is calculated as follows;
v = d/t
where;
- d is distance
- t is time
- v is speed
Distance and speed are directly proportional, thus, when the speed of the car increases by 13.3 percent, the breaking distance increases by 13.3 percent as well.
