A satellite in a circular orbit of radius R has a period of 4 h. Another satellite with orbital radius 3 R round the same planet will have a period (in hours)
A satellite in a circular orbit of radius R has an orbital period of 4 hours. For another satellite orbiting the same planet with a radius of 3R, its orbital period can be determined using Kepler's law of periods. The ratio of the orbital periods is proportional to the ratio of their orbital radii rRead more
A satellite in a circular orbit of radius R has an orbital period of 4 hours. For another satellite orbiting the same planet with a radius of 3R, its orbital period can be determined using Kepler’s law of periods. The ratio of the orbital periods is proportional to the ratio of their orbital radii raised to the power of three-halves. Substituting the values, the period ratio is (3 R/R)³/² = √27. Therefore, the period of the second satellite is √27 x 4, or approximately 4√27 hours.
T₂/T₁ = (3 R/R)³/² = √27
See lessT₂ = √27T₁ = 4√27 h.

Which stretch is performed by bending the torso forward to touch the toes?
The floor touch stretch is performed by standing upright, raising the arms, and leaning forward to touch the toes without bending the knees. This stretch targets the hamstrings, calves, and lower back muscles. It enhances flexibility, relieves tightness in the posterior chain, and improves posture.Read more
The floor touch stretch is performed by standing upright, raising the arms, and leaning forward to touch the toes without bending the knees. This stretch targets the hamstrings, calves, and lower back muscles. It enhances flexibility, relieves tightness in the posterior chain, and improves posture. Regular practice helps prevent stiffness and promotes better mobility, making it an essential warm-up or cool-down exercise for physical activities.
