Why do the kites and eagles fly without flapping their wings?

Answers

Answer 1
Answer:

Answer:

because they both have large area to capture air
Answer 2
Answer:

Answer:

Because they have a large surface area to capture moving air when going at a certain speed.

Explanation:

When your trying to fly a kite and the wind isn't that much, you have to run so that the kite can come in contact with the fast moving air which pushes the kite to go up. Just like a eagle because when a eagle is trying to fly, it has to first flap its wings to push air downwards so that it can create lift and at a certain altitude, the eagle doesn't have to flap it's wings though it tilts its body downwards a little so that gravity can do the work, so the eagle is basically gliding downward.

An object-spring system undergoes simple harmonic motion. if the mass of the object is doubled, what will happen to the period of the motion?

Answers

The period of simple harmonic motion remains unchanged when the mass of the object is doubled.

What is simple harmonic motion?

Simple harmonic motion (SHM) is a type of periodic motion where an object oscillates back and forth around a fixed point in a regular and repeated manner. It is a special case of periodic motion, characterized by a restoring force that is proportional to the displacement from the equilibrium position. The classic example of SHM is a mass-spring system, where a mass is attached to a spring and is subjected to a restoring force proportional to the displacement from its rest position.

In SHM, the motion is always sinusoidal and the period of the motion is constant, which means that the time for one complete cycle of the motion remains the same. This type of motion is important in a variety of physical systems, including the vibration of mechanical systems, the oscillations of electrical circuits, and the motion of particles in a gravitational field.

A piston above a liquid in a closed container has an area of 1m2. The piston carries a load of 350 kg. What will be the external pressure on the upper surface of the liquid?

Answers

Pressure is defined as the force exerted per unit of area. From the information given, the force exerted can be attributed to the mass of the load carried by the piston. This means that its weight is equivalent to the force it exerts.

Weight = mass(9.81) = 3433.5 Newtons
Area of piston = 1 m^2
Pressure = Force/Area = 3433.5/1 = 3433.5 N/m^2 or Pascals.
