You are on an airplane that is landing. The plane in front of your plane blows a tire. The pilot of your plane is advised to abo

rt the landing, so he pulls up, moving in a semicircular upward-bending path. The path has a radius of 450m with a radial acceleration of 17m/s2. What is the plane’s speed?

Answer:

v=87.46m/s

Explanation:

Objects moving in circular path would be have either centripetal or centrifugal  force.The force is either to center or away from center. When the object is moving along the circular path the centripetal force is

F=\frac{mv^{2}}{r}

Here m is mass, v is velocity and r is radius of circular path

The acceleration is given by:

a_{r}=\frac{v^{2}}{r}

The point of interest is lowest point on circle.The acceleration of plane at  this position point up.The speed of plane from radial acceleration equation is:

v=\sqrt{a.r}\\

Substitute 17 m/s² for a and 450m for r

So

v=\sqrt{17m/s^{2}*450m }\\ v=87.46m/s

Which statement best describes how the period and frequency of electromagnetic waves change between gamma rays and microwaves?
Dimas [21]
On an electromagnetic spectrum, one of its noticeable trends is that the wavelength increases with decreasing energy and the wavelength decrease with increasing energy. Furthermore, gamma rays have high energy and short wavelengths while microwaves have low energy and long wavelengths.

The force of Earth's gravity pulls down on a stone after someone tosses it off a cliff. What is the "equal and opposite force" d
Lapatulllka [165]

The equal and opposite force is the force of the stone's gravity pulling up on thy Earth.

<u>Explanation</u>:

                                      F_{AB} = - F_{BA}

  • When someone tosses a stone off a cliff, the force of gravity of Earth pulls down and the force of the stone's gravity pulls up on the Earth due to the equal and opposite reaction exerted between the Earth and the stone.
  • In Newton's third law, two important features are present. One is the force exerted on two bodies will have the same magnitude but opposite direction. The other feature is force is acting on two different objects.
  • This exerted force is equal in magnitude but opposite in direction whereas the gravity exerts a downward force on a stone and upward force on an Earth which is opposite in direction.
