Answer:
Sam's and Abigail speeds before colliding were a. 12.34 m/s and b. 2.86 m/s, respectively. Their total kinetic energy was diminished by c. 1484.42 J, approximately
Explanation:
By conservation of momentum, we have
Writing for each direction at a time,
Their kinetic energy changed by
Answer:
34.3cm
Explanation:
Attached is the full solution
A transform fault boundary is the correct answer.
Answer:
Weightlessness, condition experienced while in free-fall, in which the effect of gravity is canceled by the inertial (e.g., centrifugal) force resulting from orbital flight. The term zero gravity is often used to describe such a condition.
Gravitational force is an example of at-a-distance force
Option: C
<u>Explanation:
</u>
Force has both direction and magnitude it is a "vector" quantity. Force is defined as pull or push of an object resulting it to interact with two objects. There are 'Contact forces' and 'At-a-distance forces'. If two interacting objects are not in a physical contact with respect to each other the force is exerted between these two objects called 'at-a-distance' forces. This type of forces consists gravitational forces. Some of the examples of the 'at-a-distance' forces are electrical and magnetic.
