Class 11

When there is no normal force acting on a body, weightlessness is experienced, and the body free fall under gravity. The concept of gravity is still acting on the body, however, there is no weight sensation of any reaction force from any surface or ground. The weightlessness felt by the astronauts in an orbiting spacecraft is not because gravity is not present but because while they are moving forward, both, they and the spacecraft are in continuous free fall towards the Earth. The role of the normal force in defining weight can be understood from this phenomenon also how it is different from the actual gravitational force.

The gravitational pull of the Moon is the main reason behind the tides of Earth and it is less dependent on the sun. The gravitational pull of the moon on Earth is stronger than the sun's gravitational pull due to Earth's proximity to the moon. The Earth's oceans get pulled by the moon's gravity, which creates a bulge of water on the side of the Earth facing the moon. Also, another bulge gets created on the opposite side due to the water's inertia. When the earth rotates, its areas pass through these bulges which form the high and low tides. Each day, two high and two low tides are created by the gravitational interaction.

Several scholarship exams are available for Class 11 students, offering financial aid and recognition. Some notable examples include the National Scholarship Exam (NICE Foundation), KVPY, and various merit-based scholarships offered by institutions like Aakash. These scholarships can help reduce the burden of academic expenses and add value to academic and professional profiles. 

The educational institutions in Kalyan Nagar, Bangalore provide 11th Science stream education through Teachers Academy Group of Institutions Vision PU College and CMR National PU College. 

Here's a more detailed look:

Teachers Academy Group of Institutions stands out for both complete student growth alongside excellent academic programs.

The college attracts numerous students who aim to establish a solid scientific base.

The educational facility CMR National PU College works from Hennur Road through its well-designed Science programme while providing learners with optimal study conditions.

The specific "Science tungal entrance exam" for 11th grade in Pulwama is not a standard, widely recognised examination. Entrance exams for 11th grade typically vary by school and may include exams for specific Science programs or scholarships.
