Dee is on a swing in the playground. the chains are 2.5 m long, and the tension in each chain is 450 n when dee is 55 cm above t
Leno4ka [110]
Refer to the diagram shown below.

From the geometry, obtain
x = 2.5 - 0.55 = 1.95 m
cos θ = 1.95/2.5 = 0.78
θ = cos⁻¹ 0.78 = 38.74°

From the free body diagram, the tension in the chain is 450 N.
F is the centripetal force,
W is Dee's weight.

The components of the tension are
Horizontal component = 450 sin(38.74°) = 281.6 N, acting left.
Vertical component = 450 cos(38.74°) = 351.0 N, acting upward.

Answers:
Horizontal: 281.6, acting left.
Vertical: 351.0 N, acting upward.

Comment on the statement "Sharper the curve, more is the bending." ​
Tatiana [17]

The direction of the angular velocity of the minute hand of a wall-clock is perpendicular to the wall and directed inwards.

The passenger slides away from the centre of the curve.

The angle θ which a cyclist should make with the vertical while taking a circular turn of radius r with velocity v given by

tan θ = v^2/rg

Sharper the curve, smaller is the radius and greater is the value of 0.

All traditional oriental medicine recognizes that an energy force called _____ flows through the body.
valentina_108 [34]

All traditional oriental medicine recognizes that an energy force called Qi flows through the body.

Traditional Chinese medicine is predicated on the idea that qi, or the body's life force, travels along meridian channels and maintains equilibrium in a person's physical, mental, emotional, and spiritual well-being. The Feldenkrais technique is a type of somatic education that combines focused attention and gentle movement to improve human function and mobility. You can broaden your range of motion, boost your comfort level, and enhance your flexibility and coordination by using this method. This could involve your food, your workout routine, psychotherapy, relationship counseling, and more. therapies that are complementary or alternative, including acupuncture, chiropractic adjustments, homeopathy, massage, naturopathy, and others.
