Wind and amplitude creates the waves in an ordinary ocean
Convex lenses when placed in the air, will cause rays of light (parallel to the central axis) to converge.
Converging lenses, commonly referred to as convex lenses, have thicker centers and narrower upper and lower margins. The edges are outwardly curled. This lens has the ability to concentrate a beam of parallel light rays coming from the outside onto a spot on the opposite side of the lens.
The image created is referred to be a genuine image when it is inverted relative to the object. On a screen, this kind of image can be recorded. When the object is positioned at a point farther than one focal length from the lens, a converging lens creates a true image.
A virtual image is one that cannot be produced on a screen and is formed when the image is upright in relation to the object. When an item is positioned within one focal length of a converging lens, a virtual image is created. It creates an enlarged image of the object on the same side of the lens as the image. It serves as a magnifier.

Answer:
A larger force than 70 N will be required for the box to continue moving
Explanation:
A ramp is an inclined plane surface that is tilted to form a slope on its opposite sides
A ramp provides mechanical advantage or force amplification, by allowing less force to lift heavier load from having to move through a longer distance to reach a particular elevation when the slope of the ramp is gentle
Therefore, when the slope is steeper, and shorter, more force than 70 N will be required for the box to continue moving.
Answer:
its velocity is 51, or 51.42 to be exact it would be: 51.4285714286
Answer:
m1=0.72kg m2=0.48kg m3=0.98
Explanation:
12*m1=18*m2, so 2*m1=3*m2
6*(m1+m2)=24*.03, so 2*m1+2*m2=2.4
so, 5*m2=2.4, m2=0.48 then, m1=0.72
(m1+m2+0.3+0.2)*18=31*m3
1.7*18=31*m3
m3=0.98
