Answer:
Though you have not gave the choices, I do believe it is “testing”
Explanation:
Answer:
Answer: Say the big boy is 40kg and the small boy is 20kg... ... ...then by the rule that moments around a fulcrum or pivot should be equal for equilibrium, the distance of big boy from pivot=half of dist of small boy from pivot
Decreasing the mass of the car will help increase the acceleration of the car using application of Newton’s laws of motion.
<h3>
What is Newton's law of motion?</h3>
This law discusses the relationship between motion of a substance and the forces acting on it.
Heavy objects are more difficult to move which is why decrease in mass will help increase the acceleration.

Answer:
These 5 principles can be better understood from the past events as well as from formation of the sedimentary rocks
Explanation:
Principle of original horizontal- the sedimentary rocks are found to be horizontal during the initial deposits phase. If tilted this is due to the subsequent geological event.
Principle of original lateral continuity- The sedimentary beds are originally laterally continuous into their environment of deposition. Faulting in the severe folding and also erosion may leads to the separation of the originally lateral continuous beds which in later becomes separate units.
Principle of cross cutting- The younger features can get cuts across the older features. That's why faults, erosion, volcanoes etc can be seen. The above mentioned are younger than those materials that is faulted intruded, or eroded.
Principle of inclusion- Inclusion itself means (a rock fragment another rock fragment) they must be older than the materials in.
Principle of uniformity- Those are the physical process that are been seen today, were also worked in the same way in the geologic past, thus modern methods helps us to understand the ancient events.
Answer:
0.061 J
Explanation:
The kinetic energy of an object is given by
where
m is the mass of the object
v is its speed
For the toy truck in the problem, we have
m = 0.1 kg is its mass
v = 1.1 m/s is its speed
Putting the numbers into the equation, we find
