Answer:
Explanation:
Car is 25 m long . worker moves at speed 3.0 m/s with respect to the car
Time taken to reach the other end
= 25 / 3 = 8.333 s
Displacement of flatcar during this period
= 7 x 8.333
= 58.33 m
Answer:
Solid - molecules are packed together, and it keeps its shape.
Liquids - take the shape of the container.
Gases - spread out to fill the container.
b and e are the largest and equal in magnitude. 
A and d are next. aR = (3rad/s2)R = 3R
c is zero. wR = v = 0; Angular acceleration is zero.
<h3>What is angular acceleration?</h3>
- The temporal rate at which angular velocity changes is known as angular acceleration. The standard unit of measurement is radians per second per second. Therefore, = d d t. Rotational acceleration is another name for angular acceleration.
- Angular velocity divided by acceleration time can be used to define angular acceleration. (t). As an alternative, use pi times the drive speed (n) divided by the acceleration time (t) times 30. Radians per second squared (Rad/sec2) is the standard SI unit for rotational acceleration resulting from this equation.
- To calculate angular velocity, we can use one of three formulas. The definition itself provides the first. Theta = position angle, t = time, and w = angular velocity, where w = angular velocity, theta = position angle, and t = time. Angular velocity is the rate of change of an object's position angle with respect to time.
- The symbol for angular acceleration is, and it is measured in rad/s2, or radians per second square.
If two items are equal, show them as equal in your ranking. If a quantity is equal to zero, show that fact in your ranking:
b and e are the largest and equal in magnitude. 
A and d are next. aR = (3rad/s2)R = 3R
c is zero. wR = v = 0; Angular acceleration is zero.

When your'e in space you feel weightless blc there's no grsvity in space.
1. Scientists are responsible for removing plasmids, small rings of DNA, from bacterial cells.
2. The Enzymes cut open the plasmid DNA. The same enzyme removes the human insulin gene from its chromosome.
3. The human insulin gene attaches the open ends of the plasmid to form a closed ring.
4. Some bacterial cells take up the plasmids that have the insulin gene.
<span>
5. When cells reproduce, the news cells will contain copies of the engineered plasmid. The foreign gene directs the cell to produce human insulin.</span>
