Answer:
A force of μk⋅60N is needed to keep a 60-newton rubber block moving across level, dry asphalt in a straight line at a constant speed.
Explanation:
False. p waves, than s waves
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individualwaves upon the particles of the medium.Hope this help!
Answer:
1. Pure substances cannot be separated into any other kinds of matter, while a mixture is a combination of two or more pure substances.
2. A pure substance has constant physical and chemical properties, while mixtures have varying physical and chemical properties (i.e., boiling point and melting point).
Explanation:
There are several information's of immense importance already given. Let us now focus on the problem in hand.
Pressure = Force/Area
Area = 58.8 cm^2
= 0.0058 m2
Then
Pressure = (12 * 9.8)/0.0058
= 20275 Pascals
= 2 Pa
The correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your desired help.
