Answer:

This is true.

Oil has a good consistency for reduction in tight areas of something. If you've ever played a recorder for band class or just for fun, you may have realized that every time you take it apart and put it together again it gets harder, and normally the recorder comes with a small container of oil that you rub between the two connecting pieces.

A seesaw has an irregularly distributed mass of 30 kg, a length of 3.0 m, and a fulcrum beneath its midpoint. It is balanced whe
gladu [14]

Answer:

x = 0.9 m

Explanation:

For this exercise we must use the rotational equilibrium relation, we will assume that the counterclockwise rotations are positive

          ∑ τ = 0

          60 1.5 - 78 1.5 + 30 x = 0

where x is measured from the left side of the fulcrum

           90 - 117 + 30 x = 0

           x = 27/30

           x = 0.9 m       

In summary the center of mass is on the side of the lightest weight x = 0.9 m

An isotope undergoes radioactive decay by emitting radiation that has no mass. What other characteristic does the radiation have
vitfil [10]

Other characteristic of radiation is the presence of positive and negative charge.

<h3 /><h3>What other characteristic does the radiation have?</h3>

Positive or negative charge are the other characteristic that is present in the radiation. Beta radiation have negative charge while on the other hand, alpha radiation have positive charge.

So we can conclude that other characteristic of radiation is the presence of positive and negative charge.

pychu [463]

Answer:

225 m

Explanation:

f = Frequency of the T wave = 6.8 Hz

v = Speed of sound in seawater = 1530 ms⁻¹

\lambda = Wavelength of the T wave

we know that, frequency, speed and wavelength are related as

wavelength = \frac{speed}{frequency}

\lambda = \frac{v}{f}

Inserting the values, we get

\lambda = \frac{1530}{6.8}\\\lambda = 225 m
