If the mass of earth is 80 times of that of moon and its diameter is double that of moon and g on earth is 9.8 m / sec², then the value of g on moon is
The acceleration due to gravity is denoted by g , which on Earth comes out to be about 9.8 m/s². It indicates the strength of the pulling force that the Earth exerted upon the objects resting on it due to mass and radius. It pulls all these objects towards the center due to gravitational force, wherRead more
The acceleration due to gravity is denoted by g , which on Earth comes out to be about 9.8 m/s². It indicates the strength of the pulling force that the Earth exerted upon the objects resting on it due to mass and radius. It pulls all these objects towards the center due to gravitational force, where this gravitational force is said to provide weight to them.
When we think of the Moon, the gravitational acceleration is much lower than that of Earth. This is what is called g’ . The Moon’s mass is approximately 1/80th that of Earth, and its radius is about half that of Earth. Thus, the gravitational force felt on the Moon is much weaker.
From calculations of gravitational acceleration on the Moon, it was determined that this acceleration is around 0.49 m/s². This smaller gravitational pull impacts the behavior of objects on the Moon’s surface greatly. For instance, if a person weighed 100 kg on Earth, then he or she would weigh about 6.1 kg on the Moon. This is because the movements are easier, and it is possible to jump higher because the gravitational force is less. This difference in gravity serves to play a crucial role in many scientific and engineering applications pertinent to lunar exploration and habitation.
For earth,
g = GM/R² = 9.8 ms⁻²
For moon,
See lessg’ = (G(M/80))/(R/2)² = 1 GM/20 R²
= 1/20 x 9.8 = 0.49 ms⁻²
Explain why the reactance offered by a capacitor decreases with increasing frequency of an alternating voltage.
The reactance offered by a capacitor decreases with increasing frequency because reactance (XC) is inversely proportional to the frequency of the alternating voltage, as given by the formula XC = 1/2πfC, where f is the frequency and C is the capacitance. As the frequency increases, the rate of changRead more
The reactance offered by a capacitor decreases with increasing frequency because reactance (XC) is inversely proportional to the frequency of the alternating voltage, as given by the formula XC = 1/2πfC, where f is the frequency and C is the capacitance. As the frequency increases, the rate of change of voltage across the capacitor becomes faster, allowing it to charge and discharge more rapidly, reducing the opposition to current flow.

What are the key techniques for maintaining balance while performing a pole dive?
Maintaining balance during a pole dive requires planting the lead foot firmly near the pole and keeping the body low to the ground. The free arm should be used for stability and control, while the torso generates momentum for the dive. Controlled movements and focused attention on the target help prRead more
Maintaining balance during a pole dive requires planting the lead foot firmly near the pole and keeping the body low to the ground. The free arm should be used for stability and control, while the torso generates momentum for the dive. Controlled movements and focused attention on the target help prevent slips or loss of balance. Practicing these techniques consistently refines the skill, making players more confident and effective during pole dives in matches.

Proper breathing is crucial for sustaining stamina during kho-kho matches. Deep, controlled breaths ensure efficient oxygen delivery to muscles, reducing fatigue and maintaining energy levels. During intense chases or defensive moves, focusing on rhythmic breathing prevents shortness of breath and helps players stay calm under pressure. Regular practice incorporating breathing exercises enhances lung capacity, enabling players to perform consistently and recover quickly during the physically demanding phases of the game.

A chaser’s speed is critical in kho-kho as it allows them to close gaps with defenders efficiently. Quick bursts of speed enable rapid changes in direction, giving the chaser an advantage during high-pressure situations. By practicing drills like shuttle runs and acceleration exercises, players canRead more
A chaser’s speed is critical in kho-kho as it allows them to close gaps with defenders efficiently. Quick bursts of speed enable rapid changes in direction, giving the chaser an advantage during high-pressure situations. By practicing drills like shuttle runs and acceleration exercises, players can improve their speed and timing. Enhanced speed not only improves tagging efficiency but also adds to the team’s overall agility, increasing the chances of outmaneuvering opponents during matches.
