<h2>Answer:</h2>
→ Friction resists motion
→ Friction is a contact force.
→ Friction is caused by microscopic bumps and ridges on surfaces.
<h2>Explanation:</h2>
As the normal force, the friction is a contact force because it result when two objects interact by a direct contact, that is, touching to each other. Friction is important in everyday life and resists motion. For example, the oil in a car engine minimizes friction between moving parts, but a car can move because the friction between the tires and the road, but <em>what about the microscopic level?</em> well, as the normal forces friction forces result from the intermolecular forces between two rough surfaces at points where they come into contact and they are electrical in nature.
Answer:
3.2
Step-by-step explanation:
First, evalue what's inside of the absolute value:
3.1 + (-6.3) = -3.2
Now, since absolute value means the distance from the number to 0, the absolute value of -3.2 is the negation of -3.2:
|-3.2| = 3.2
(3/4)∗π∗62=27π
Also , the goat can reach around the corners by 2 on the short sides and 1 on long side.creating 2 90 degree sectors of additional grazing area.(1/4)∗π∗22=π
(1/4)∗π∗12=π/4
27π+π+π/4=28.25π
Answer: 37.5
