A flare is dropped from an airplane flying horizontally at uniform velocity (constant speed in a straight line). Neglecting air
jolli1 [7]

Answer:

Option B (remain vertically under the plane) is the correct option.

Explanation:

  • A flare would follow a particle trajectory with horizontal direction somewhat like airplane velocity as well as initial maximum motion as null but instead, gravity will induce acceleration. It would be lowered vertically underneath the plane before flare had already sunk to something like the surface.
  • There is no different movement in the airplane nor even the flash. And none of them can change its horizontal level.  

Some other alternatives are given really aren't linked to the specified scenario. So choice B is the perfect solution to that.

The sound emitted by bats has a wavelength of 4.13 mm.
blagie [28]

Answer:

the frequency of a wave is equal to the linear speed divided the wavelength. so in equation form.

f = v / l

where f is the frequency

v iss the linear speed

l is the wavelength

f = ( 345 m/s ) / ( 4.38 mm ) ( 1 m / 1000 mm )

f = 78767 per second

Explanation:

hope it helps

A car of mass 1000.0 kg is traveling along a level road at 100.0 km/h when its brakes are applied. Calculate the stopping distan
OleMash [197]

Explanation:

It is given that,

Mass of the car, m = 1000 kg

Speed of the car, v = 100 km/h = 27.77 m/s

The coefficient of kinetic friction of the tires, \mu_k=0.5

Let f is the net force acting on the body due to frictional force, such that,

-f=ma

a=\dfrac{-f}{m}

a=\dfrac{-\mu _k mg}{m}

a=\mu_k g

a=-0.5\times 9.8

a=-4.9\ m/s^2

We know that the acceleration of the car in calculus is given by :

v.dv=a.dx, x is the stopping distance

\int\limits^0_v {v.dv}=\int\limits^x_0 {a.dx}

\dfrac{v^2}{2}|_v^0=ax

0-(27.77)^2=-2\times 4.9x

On solving the above equation, we get, x = 78.69 meters

So, the stopping distance for the car is 78.69 meters. Hence, this is the required solution.
