This is the new year with new goals, new experiences and lots of exams to be scheduled soon. SSC CGL has recently released the exam dates so now it is time to gear up your preparations and try hard to get the success. ADDA247 never fails to deliver something new and fruitful for you all. This time also we are providing you the best study plan as well as a study material. We are here going to prepare your General Science section for the SSC CGL. In this article, we are providing you the details that how we are going to help you to clear the examination this year. We ADDA247 is going to provide you daily tests for all the subjects. The topic-wise quiz will be done from January till April. This will help you to get a deeper knowledge of all the topics and will prepare you thoroughly.

Sol.The shape of a velocity versus time graph reveals pertinent information about an object’s acceleration.
Sol.An MRI (magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures.
Sol.Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons by the photovoltaic effect. Solar cells produce direct current electricity from sunlight which can be used to power equipment or to recharge a battery.
Sol.Motor convert electrical energy into mechanical energy.
Sol. Dynamo convert mechanical rotation into electric power.
Sol.A satellite derives energy from gravitational field in vaccum.
Sol. The force of attraction is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Sol.Newton defines law of graviatation.
Sol.The hair of shaving brush clings together when removed from water due to surface tension.
Sol.A drop of liquid assumes spherical shape because of least surface area for a given volume.
In the last month i.e. in May daily we will provide you with a test of the previous years’ question papers, this will increase your confidence of solving the real exam and will make you familiar with the real-time exam.
