Answer:
- The image will be located at -13 cm
- The height of image is 5.2 cm
Explanation:
First you should remember that the images produced by convex mirror is virtual.
In this question, you should find the focal length using the radius of curvature, then apply the focal length relationship to find the image distance which is a virtual distance and finally use the magnification relationship to find the image height.
Let;
- height of object=h
- distance of object from mirror=o
- radius of curvature=r
- image distance=i
- height of image=h'
- focal length=f
<u>Find the focal length</u>
f=focal length is half the radius of curvature
f=r/2=34/2 =17cm =0.17m (This distance is virtual thus include a -ve sign)
f= -0.17m
<u>Apply the focal length relationship</u>
Solve for the reciprocal
This is a virtual distance for the virtual image formed
<u>Apply the magnification relationship</u>
Magnification = height of image÷height of object
or
Magnification= - image distance÷object distance
This would be called the law of action-reaction. This states that every action will have an equal and opposite reaction. The action in the example is pulling down on the rope. The opposite and equal reaction is the climers body moving upward. The same law can be applied to a rocket. The action is the engines pushing down and the reaction is the rocket going up. :D
To throw an object into the space you need to throw it with the escape velocity of the earth which is 11.2 km/sec. therefore if you can throw an object with the speed of 11.2 km/sec it will leave the earth atmosphere and will reach to the space.
Answer:
bias refers to effects that a conclusion that may be incorrect, as for example when a researcher patient knows what treatment is being given, to avoid bias a blinded study may be done
