Answer:
Therefore, the distance between object and image is given by the distance between object and mirror + distance between mirror and image = 0.5 m + 0.5 m = 1 m. 4. You are provided with a concave mirror, a convex mirror, a concave lens and a convex lens. To obtain an enlarged image of an object you can use either (a) concave mirror or convex mirror.
Explanation:
There are various properties which are exhibited by substances like physical properties,chemical properties,magnetic properties,electric properties etc.
By simply observing the substance we can not get any idea about the property of a substance.One has to conduct various tests in order to reach at his or her conclusion. The scientific tests provides a better understanding about the nature of substance and the changes that happen under various conditions and parameter.

Answer:
The banking angle is 23.98 degrees.
Explanation:
We have,
Radius of a curve is 35 m
Speed of a car is 7 m/s
It is required to find the banking angle. At equilibrium, net force is equal to the centripetal force between vehicle and the road such that the banking angle is given by :
g is acceleration due to gravity
So, the banking angle is 23.98 degrees.
Answer:The “event horizon” of a black hole is the point of no return. That is, it comprises the last events in the spacetime around the singularity at which a light signal can still escape to the external universe. For a standard (uncharged, non-rotating) black hole, the event horizon lies at the Schwarzschild radius.
