2. The convex mirror shown below has an object placed 15cm in front of it. An image is formed 35 cm from the mirror. What is the nature of the image? Calculate the magnification of the image and the focal
length of the mirror.

Mass (kg) force (n) 5 25 10 50 15 75 20 100 a student was trying to find the relationship between mass and force. he placed four different masses on a table and pulled them using a spring scale. the table shows the different masses used in the experiment and the force required to pull each mass. the student concluded that more force was required to pull heavier objects. what comment would you make regarding his conclusion? a) no clear relation can be observed between mass and force from the data. b) there is a direct proportion between the mass and force listed in the table. c) gravity should have been taken into account while performing the experiment. d) there is an inverse proportion between the mass and force listed in the table.

What is the speed of an object at a given moment?

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?
