The correct answer is B. Fuse.
Fuses were commonly used in houses up to recent ages, when circuit breakers became the more popular options, as they don't have to be changed every time they melt, since they don't melt.
The answer is D. Unconditioned
The response to an unconditioned stimulus that occurs naturally without learning and involuntarily triggers reaction is known as an unconditioned response. For example, you smell your favorite food while being cook may make you instantly feel hungry.
Answer:
Moment of inertia is the inertia of a rotating body with respect to its rotation. So basically it's the object's resistance to a rotational acceleration. This relates to Newton's first law! What does that exactly mean? Let's check out the explanation.
One formula that it is written in is I= mr
Explanation:
As Bill Nye says, "Inertia is a property of matter. Objects that are not moving don't move unless they get pushed or pulled. Moving objects keep moving unless they get pushed or pulled. This feature of objects and materials is what we call inertia."

Answer:
Explained
Explanation:
If you are in a rotating system newton's law do not work .Adding a frictious force can make the law work. If an orbiting object is in constant freefall under gravity . Even elliptical planet orbits are examples of freefall under gravity. The force F which the planet feels; this force can be resolved into two components, centripetal force F_C and tangential force F_T.
The tangential force causes an acceleration(newton's second law) which decreases the speed and the centripetal force causes the velocity to turn. In there is circular orbit of radius R, F_T=0 and the centripetal force is F_C=Mv^2/R;
The centrifugal force would be a vector with magnitude Mv^2/R( same as that of centripetal) pointing away from the sun but it does not really exist.
Answer:
This question heavily relies on the weight of the table and the weight of the person sitting on it, if a 90 pound person sits on the side of a 40 pound table, it will topple over.
Explanation: Tables are generally have a 50/50 weight distribution ratio so that they are even on the ground and can stay upright, but if a table is too light and the person or object sitting on it is heavier than the side they/it is placed on, it will fall.
