False, Gamma Rays are the smallest because gamma rays have the shortest wave length
Explanation:
The Hubble telescope was launched in 1990, in the low Earth orbit and remains in operation. It was built by NASA with contributions from European Space Agency. There was a serious problem with the optical system and the analysis showed that the cause is the primary mirror that had been polished to the wrong shape, introducing spherical aberration. It was solved by sending servicing mission in 1993, by installing a set of specialized lenses to correct the flawed main mirror in the telescope. Including this, there have been total five astronaut servicing mission to Hubble.
Answer:
a.
Explanation:
Remeber speed and velocity are the same concept, it just speed is scalar, meaning it doesn't have a direction nor it negative.
So technically thr car had a constant speed over 75 seconds.
If thr car has a constant speed, the car isn't speeding up or slowing down so it has accleration of 0 so the answer is a.
Answer:
a) Shadow distance
10 cm in front of the mirror.
b) Zoom in the shadow
The shadow formed is the same height as the object and is placed also at the centre of curvature of the mirror as shown in the attached image to this solution.
c) The nature of the shadow
The shadow formed is real, inverted, same size as the object and formed at the centre of curvature.

Objects as high as 3 cm are placed at a distance of 10 cm in front of a concave mirror with 10 cm curvature. Determine:
a) Shadow distance
b) Zoom in the shadow
c) The nature of the shadow
Solution
The mirror equation is given as
(1/f) = (1/v) + (1/u)
f = focal length of the mirror = (radius of curvature)/2 = 10/2 = 5 cm
v = image distance = ?
u = object distance = 10 cm
We can then calculate the shadow' s distance from the mirror thus
(1/5) = (1/v) + (1/10)
(1/v) = 0.2 - 0.1 = 0.1
v = (1/0.1) = 10 cm
b) Zoom in the shadow
Since the object is placed at the centre of curvature, as shown in the attached image, the image is formed at a point of intersection of rays. The image formed is the same height as the object and is placed also at the centre of curvature of the mirror.
c) The nature of the shadow
Since the mirror is a concave mirror, the image is real and formed in front of the mirror. The image is also inverted and formed at the centre of curvature of the mirror.
Hope this Helps!!!
