If the velocity of a moving object is doubled, its kinetic energy quadruples. This relationship is governed by the kinetic energy formula, which is proportional to the square of the velocity. Therefore, the correct answer is [C] Kinetic energy quadruples.
When a boy sits on a rotating round table, the angular velocity will decrease. This decrease occurs due to the conservation of angular momentum. The addition of mass increases the moment of inertia, causing a reduction in angular velocity to ...
When the girl stands up from swinging in a sitting position, the time period of the oscillations will increase. This change occurs because her center of mass rises, altering the swing’s dynamics. As a result, the swing takes longer to ...
The part of the eye used in eye donation is the Cornea. During eye donation, the cornea, the transparent outermost layer of the eye, is typically harvested for transplantation to restore vision in individuals with corneal disorders or injuries.
Cornea is a part of the Eye. It is the transparent, outermost layer covering the front of the eye. The cornea plays a crucial role in focusing light onto the retina and protecting the eye from dust, germs, and other ...
Due to the accumulation of Lactic acid in the muscles, a person feels tired. Lactic acid buildup occurs during intense physical activity when oxygen supply to the muscles is insufficient, leading to fatigue and muscle soreness.
The property of self-vibration is found in the Heart muscle. The heart has its inherent electrical conduction system, allowing it to generate rhythmic contractions without external stimulation. This property facilitates the heart’s vital function of pumping blood throughout the body.
The most powerful muscle of the human body is the Jaw. The jaw muscles, specifically the masseter and temporalis muscles, exert significant force during activities like chewing and biting, making them exceptionally strong compared to other muscles in the body.
The total number of muscles in the human body is 639. These muscles vary in size, shape, and function, enabling movement, supporting the body’s structure, and facilitating essential bodily functions such as digestion, respiration, and circulation.
