i think the answer is b kk good luck
Explanation:
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.

Answer: Velocity = v = 35 m/s
Explanation:
Kinetic energy of an object is defined as the energy possess by an object due to its motion. Kinetic energy K.E of an object is equal to the half of the mass of that object multiplied by square of the object's velocity.
Mathematically,
v = 35 m/s
<h2>Answer: A lever
</h2>
The catapult is basically a type of simple lever or first class lever, which is a device used to transmit force and displacement to an object, by means of the amplification of the applied mechanical force, thus increasing its speed or distance traveled.
These simple levers are composed of a rigid bar that can rotate freely around a <u>point of support</u> (the fulcrum). However what differentiates them from the other levers is that the <u>fulcrum</u> is between the point where the <u>effort</u> must be applied and the point where the <u>resistance</u> is.
With this configuration it is posssible to make several arrangements, depending on the purpose to be achieved, either control and decrease the speed and distance traveled by the object or increase it.
Answer:
c. The normal force exerted on the skier by the hill is less than the weight of the skier.
Explanation:
Hi there!
Please see the attached figure for a better understanding of this explanation:
The vertical forces that act on the skier are the normal force (N) and the vertical component of the weight (wy) (see figure). Since the skier is not being accelerated in the vertical direction (perpendicular to the surface), the resulting net force acting in the vertical direction is zero:
∑Fy = 0
N - wy = 0
<u>N = wy</u>
The vertical component of the weight is calculated using trigonometry of right triangles:
cos θ = adjacent / hypotenuse
cos θ = wy / W
W · cos θ = wy
Since:
cos θ < 1
Then:
W · cos θ < W
Then:
wy < W
and then:
<u>N < W</u>
The correct answer is "c": the normal force exerted on the skier by the hill is less than the weight of the skier.
