1. C. Upper Left
2. B. For about 90% of their lifetime
The average velocity of Alyse is 0 m/s.
<h3>What is the average velocity of an object or a person?</h3>
The average velocity of a person is the average of all the velocities of moving as it moves.
Velocity on its own is the ratio of the displacement of a body and the time taken for that displacement.
Mathematically:
- Average velocity = total displacement / time taken
Displacement is a vector quantity that measures the distance traveled by a moving body in a specific direction.
Hence, average velocity and velocity are both vector quantities.
Displacement takes a measure of the shortest possible distance along a straight line from the beginning of the motion until the end of the motion.
Calculating the average velocity of Alyse:
Assuming the initial direction is positive and n=backeard direction is negative:
Total displacement = 20 m + - (20 m)
Total displacement = 0 m
total time = 3 minutes
Average velocity = 0 m/ 3
Average velocity = 0 m/s

Answer:
They decompose dead things and absorb the nutrients and get their food
Answer:
V = 31.62 m V
Explanation:
Given,
Voltage across thick membrane = ?
Thickness of the membrane, d = 5.5 n m
Electric field = 5.75 M V/m
we know
V = E d
V = 5.75 x 10⁶ x 5.5 x 10⁻⁹
V = 31.62 x 10⁻³ V
V = 31.62 m V
Hence, The Voltage across the membrane is equal to 31.62 m V.
