a rocket lift off the surface of earth with a constant acceleration of 20 m/sec^2 .how fast will the rocket be going 1 min latter?
Answers
20m/s * 60 s = 1200 m/s
and its speed becomes 20 m/s greater every second.
Since it started out with zero speed, its speed after 1 minute
(60 seconds) is
(20 m/s /s) · (60 s) = 1,200 m/s .

I used the Lens Equation:
Where:
obj. is the distance of the object
im. is the distance of the image
f is the focal length
Final answer:
The image formed by the convex lens is real, located 10.91 cm to the right of the lens, and is inverted. The ray diagram would show rays from the object converging at the image point after passing through the lens.
Explanation:
In order to draw a ray diagram and find the location of the image for an object placed 30.0 cm to the left of a convex lens with a focal length of +8.0 cm, we first utilize what is known as the lens formula, which is 1/f = 1/do + 1/di. Here, f is the focal length of the lens, do is the object distance, and di is the image distance.
In the given question, the object distance (do) is -30 cm (the negative sign indicates that the object is on the same side of the lens as the light source), and the focal length (f) is +8 cm. Plugging these values into the lens equation, we find that 1/di = 1/f - 1/do = 1/8 - 1/(-30). Solving this, we get di = 10.91 cm.
This positive value for di means the image is real, meaning it can be projected onto a screen, and appears on the opposite side of the lens from where the object is. The magnitude of the image distance indicates the image is 10.91 cm from the lens.
To determine the orientation of the image, we use the magnification formula, m = -di/do. Substituting the given values into this formula, we get m = -10.91 / -30 = +0.36. Since this value is positive, the image is inverted. The image would appear smaller than the object because the absolute value of the magnification is less than 1.

Answer: Option (c) is the correct answer.
Explanation:
In order to reduce the velocity of wind there should be some placed some barrier near the field. So that when fast moving wind strikes at the surface of barrier then its speed will decrease.
Therefore, the farmer Wilcox should plant trees around the perimeter of his fields which will act as a barrier to the fast moving winds.
