The x-component of the vector is 36.55 m.
The components of a vector include both x and y components. The x-component is determined along x-axis, while y-component is determined along y-axis.
Vx = Vcosθ
Vy = Vsinθ
where;
The x-component of the vector is calculated as follows;
x = 47.3 x cos(39.4)
x = 36.55 m
Thus, the x-component of the vector is 36.55 m.

The question is about Distance and Displacement. Distance, a scalar quantity, represents the total path length traveled between two positions, whereas displacement, a vector quantity, refers to the change in position from the starting to the final point, including direction.
When comparing distance and displacement in the field of science, specifically physics, there are key differences to keep in mind. Distance is a scalar quantity that refers to the total length of the path traveled between two positions. In contrast, displacement is a vector quantity—and thus includes both magnitude and direction—that represents the change in position of an object from its starting point to its end point.
Let's consider an example where you drive from home to school which is 5 km away, then return back home. In this case, the distance you traveled is 10 km because distance simply adds up all the lengths covered. However, the displacement is 0 km because displacement considers the direct path from the starting position to the final position; since you returned home, your initial and final positions are identical, and so the change in position is null.
Therefore, it's important to note that while distance and displacement can sometimes share the same magnitude, they are distinct in that displacement always includes direction. Distance is just a measure of how far an object has travelled, while displacement tells you how far and in which direction it is from the starting point.

Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.

Explanation:
Polonium is not flammable, although highly reactive and can reach temperatures of up to 500°C
B. pulley
C. wedgd
D. inclined plane
The inclined plane is the best simple machine to assist with moving heavy objects into a truck. It allows for less force to be used by distributing the required force over a longer distance.
The simple machine that is best suited to assist with the task of moving heavy objects into a moving truck 1.5 meters above the ground is the inclined plane (option D).
An inclined plane is a flat surface that is inclined or sloped, which allows us to move objects up or down with less force. By using an inclined plane such as a ramp, we can reduce the amount of force needed to lift the heavy objects into the truck.
For example, instead of trying to lift a heavy object straight up into the truck, which would require a significant amount of force, we can use an inclined plane to gradually raise the object by pushing it up the inclined surface. This allows us to distribute the required force over a longer distance, making it easier to move the object.
