Answer:
An inclined plane makes work easier by breaking an upward or downward movement into smaller increments. Examples of inclined planes include slides, ramps, and hills. A screw is like an inclined plane wrapped around a cylinder. A screw turns a small rotational force into a larger forward driving force.

Answer:
xtotal = 90km
displacement = 18km N
Explanation:
To find the total distance traveled by the car, you first calculate the distance traveled by the car when it travels to north. You use the following formula:
(1)
x: distance
v: speed of the car = 30 m/s
t: time = one half hour
In order to calculate the distance you convert the time from hours to seconds:

Then, you replace the values of t and v in the equation (1):
(2)
Next, you calculate the distance traveled by the car when it travels to south:

You convert the time from minutes to seconds:


Finally, you sum both distances x and x':

The total distance traveled by the car is 90km
The total displacement is the final distance of the car respect to the starting point of the motion. This is calculated by subtracting x' to x:

The total displacement of the car is 18km to the north from its starting point of motion.

Answer;
C.It is the minimum amount of material needed to sustain a fission reaction.
Explanation;
-A critical mass is the smallest or the minimum amount of fissile material needed for a sustained nuclear chain reaction. A critical mass must be achieved in order for the chain reaction to continue and release the atomic energy. A critical mass is needed for both a nuclear reactor and an atomic or hydrogen bomb.
-The critical mass of a fissionable material depends upon its nuclear properties (specifically, the nuclear fission cross section), its density, its shape, its enrichment, its purity, its temperature, and its surroundings.
