The answer is the vehicle. At the precise moment of the impact in a collision, there is the release of energy when a vehicle strikes another vehicle or another object. Earlier to an impact, a vehicle and everything inside the vehicle is traveling at whatever speed the vehicle had been going. As the collision continues, the vehicle slowly loses energy. However, the vehicle occupants and any others items in the vehicle continue to move forward at the same speed as the vehicle had been traveling prior to impact.

7) Se calcula dividiendo distancia entre tiempo
sveta [45]

Answer:

A) Rapidez

Explanation:

Speed is a scalar quantity and it is found by dividing the distance traveled by the time taken.

 Speed  = \frac{distance}{time}  

Distance is the length of path covered whereas time is the duration of the travel.

Unlike velocity which is a vector, speed is a scalar quantity with only magnitude but no direction.

A chamber 5.0 cm long with flat, parallel windows at the ends is placed in one arm of a Michelson interferometer (see below). Th
Ivahew [28]

Answer:

1.00029

Explanation:

A wave is a disturbance which travels through a medium and transfers energy without displacing the medium itself.

interference is one of the characteristics of a wave motion

The Michelson interferometer produces interference fringes by splitting a beam of monochromatic light so that one beam strikes a fixed mirror and the other a movable mirror. When the reflected beams are reflected, an interference pattern results.

∝Δm=Δud

∝=wavelength  500nm

Δm=number of fringes

d=length 9f the  Michelson interferometer chamber

Δu= change in refractive index

500*10^-9*29=0.05*Δu

Δu=0.00029

REFRACTIVE INDEX=1+0.00029

A spacecraft travels at 1.5 X 108 m/s relative to Earth. A process onboard the
kvasek [131]

Answer:

73.6 minutes

Explanation:

relative time = time interval / √(1 - observer velocity² / speed of light²)

we have relative time. we want time interval.

rearrange

time interval = relative time x √(1 - observer velocity² / speed of light²)

convert 85 mins into seconds

85 x 60 = 5100

1.5 x 10⁸ as a number is 150000000

for c = 299 792 458

time interval = 5100 x √(1 - 150 000 000² / 299 792 458²)

for c = 3 x 10⁸

time interval = 5100 x √(1 - 150 000 000² / 300 000 000²)

time interval = 5100 x 0.866

time interval = 4415.71

divide by 60 for back into minutes

time = 73.6 minutes

A ball, with a mass of 5.9kg, is thrown directly upwards. It reaches a maximum height of 10m from the point at which it was rele
katrin2010 [14]

Answer:

14 m/s

Explanation:

We can solve the problem by using the law of conservation of energy.

At the beginning, when the ball is thrown from the ground, it has only kinetic energy, which is given by

K=\frac{1}{2}mv^2

where m = 5.9 kg is the mass of the ball and v is its initial speed.

As the ball goes up, its speed decreases, so its kinetic energy decreases and converts into gravitational potential energy. When the ball reaches its maximum height, the speed has become zero, and all the kinetic energy has been converted into gravitational potential energy, given by:

U=mgh

where g = 9.8 m/s^2 is the gravitational acceleration and h = 10 m is the maximum height reached by the ball.

Since we can ignore air resistance, energy must be conserved, so the initial kinetic energy must be equal to the final potential energy of the ball, so we can write:

K=U\\\frac{1}{2}mv^2=mgh

And we can solve the equation to find v, the initial speed of the ball:

v=\sqrt{2gh}=\sqrt{2(9.8 m/s^2)(10 m)}=14 m/s

igor_vitrenko [27]

Answer:

Both technicians are correct

Explanation:

In automobiles, governors are being used. Governors are also known for speed limiters as they can regulate and measure the speed of the automobile.

Hydraulic Transmission: Shifting is controlled by mechanical sensors according to vehicle speed and throttle position/manifold vacuum through valving operated by hydraulic 'pilot' signals.

Electronic Transmission: Shifting is controlled by an on-board computer that receives signals from electronic sensors.
