A wave is moving toward the shore If its frequency is 2.7 hertz, what is its wavelength? What would the correct number of signif
ArbitrLikvidat [17]

Answer:

λ = 1.1×10⁸ m

Explanation:

Given data:

Frequency of wave = 2.7 Hz

Wavelength of wave = ?

Solution:

Formula:

Speed of wave = frequency × wavelength

Speed of wave = 3×10⁸ m/s

now we will put the values in formula.

3×10⁸ m/s = 2.7 s⁻¹ × λ

λ = 3×10⁸ m/s /2.7 s⁻¹

λ = 1.1×10⁸ m

Question 14 of 17
artcher [175]

Since Lutetium-177 is a beta and gamma emitter, the daughter nuclide produced from the decay of this radioisotope is 177Hf.

Beta emission of a radioisotope yields a  daughter nuclide whose amass number is the same as that of its parent nucleus but its atomic number is greater is greater than that of the parent nucleus by 1 unit.

Also, gamma emission does not lead to any change in the mass number of atomic number of the daughter nucleus produced.

Hence, the stable daughter nuclide, 177Hf is produced.

CH, +<br> ,<br> 0, → _CO, +<br> Н,0<br> Balance chemical equation
Flura [38]

Answer:

2 CH2 + 3 O2 = 2 CO2 + 2 H2O

Explanation:

This is what I think that you meant by the question listed. When balancing a chemical equation, you want to make sure that there are equal amounts of each element on each side.

Originally, the equation's elements looked like this: 1 C on left & 1 C on right; 2 H on left & 2 H on right; 2 O on left and 3 O on right. Because these are not balanced, you need to add coefficients.

When adding coefficients, you need to make sure that all of the elements stay balanced, not just one that you are trying to fix. I know that some equations are really difficult to balance, and when that is the case, there are equation balancing websites that can help out.

However, what always helps me is making a chart and continuing to keep up with the changes I am making. It is a trial and error process.

How many milligrams of a 20mg sample of cesium-137 remain after 60 years
andrey2020 [161]
Cs -137 has a half life of about 30 years. If 60 years pass, there is two half lives passed so 1/2 * 1/2= 1/4. Take 1/4 and multiply it with the mass given:
(1/4)*20mg=5mg left
