Answer:
True
Explanation:
A convex mirror is a mirror whose outer bulging surface is the reflecting surface.
A convex mirror is used to see the distant objects and the image formed by the convex mirror is always erect and small. So, it is used as the rear view mirror.
It always forms a virtual, erect and diminished image of a real object.
It never forms a real image of a real object.
B show the potential energy and the kenetic energy
If the twin in the spaceship travels at a speed close to the speed of light, seen from Earth, the time of the traveling twin passes very slowly. Therefore, upon returning to Earth, less time has passed for him, compared to the twin who remains on Earth, that is, he is younger, while the twin who remains on Earth is older.
A changing magnetic field
Part a)
since steelhead jump under the influence of gravity
So we will use kinematic equations
here at the maximum position we know that final speed will be zero
now we will have
so the maximum height that it can reach will be 3.26 m
Part B)
now if it reaches to height 1.8 m with initial speed 8 m/s
so here we will have
