Answer:

The resulting net force is 650N

Explanation:

The force caused by air resistance against the plane's motion is called the Drag force. It acts against the motion of the plane. However, tailwinds push the plane from its tail and they apply a force is the direction of the moving plane.

The resulting force is the sum of the two forces; 450N +200N = 650N

A stone takes 5.4 seconds to fall from the top of a cliff. The cliff is
Allushta [10]

Answer:

143

Explanation:

Using one of the 3 fundamental equations in physics, y=vo*t+1/2gt^2, we can use this equation to find the total distance that was traveled.

Acceleration due to gravity is always 9.8m/s^2 and time is 5.4s, we also have no initial velocity.

Given this, we can plug in the known variables.

y=0t+1/2*9.8*5^2

simplify,

y=4.9*5.4^2

y=4.9*29.16

y=142.884m which we can round up to 143 meters

Final Answer: 143 meters

The part of a longitudinal wave where the particles are spread apart is called a______?
Zielflug [23.3K]
The answer is Rarefactions.

These are the parts of a wave that are further apart and the ones that are close together are called compressions.

I don’t think it is any of the choices stated above!

How much time is required for 48.96 C of charge to move through an electric juicer if the current through the juicer is 1.39 A?
OleMash [197]
The relationship between the charge flowing through a conductor, the current flowing through the conductor and the time is:
Q = It
Where Q is the charge, I is the current and t is the time of application of the current. Substituting the values:
48.96 = 1.39 x t
t = 35.2 seconds

I need some help w/ this:

Answer:

The velocity of the police car is, v = 17.798 m/s

Explanation:

Given data,

The actual frequency of the siren, f = 2010 Hz

The observed frequency of siren is, f' = 2120 Hz

The velocity of the observer, v' = 0 m/s

The velocity of the source, v = ?

The formula for Doppler effect,

                            f'=\frac{(V+v')}{(V-v)}f

Where,

                         V - velocity of sound waves in air.

                          v=V-(V+v')\frac{f}{f'}

Substituting the given values,

                         v=343-(343+0)\frac{2010}{2120}

                                 v = 17.798 m/s

Hence, the velocity of the police car is, v = 17.798 m/s
