Answer:

14.5 joules

50.5 %

Explanation:

Energy initial +work= energy final

28.7 + work = 14.2

friction did - 14.5 joules of work so percantage of work lost is just 14.5/28.7 *100 or 50.5 %

A star’s light is alternately shifted from the blue part of the light spectrum to the red part.
g100num [7]
The answer is A because it is an example of red shift which if basically the Doppler effect , but for light. The wavelength gets longer because it has visible light has shifted into the red end of the spectrum, showing that it has a shorter frequency with a longer wavelength; meaning it is moving away from us

Dos coches, uno de 1.000 kg que circula a 100 km/h, y otro de 1.200 kg que circula a 90

The collision of car 2 is more violent (because more impulse is exerted)

Explanation:

The collision which is more violent is the one in which more impulse is exchanged.

The impulse exerted by each car on the wall is equal to the change in momentum of the car:

I=m\Delta v

where

m is the mass of the car

\Delta v is the change in velocity

For the car 1,

m = 1000 kg

\Delta v = -100 km/h \cdot \frac{1000 m/km}{3600 s/h}=-27.8 m/s (the sign is negative because the velocity of the car has changed from 100 km/h to 0 km/h)

So the magnitude of the impulse of car 1 is

I_1 = (1000)(27.8)=27,800 kg m/s

For the car 2,

m = 1200 kg

\Delta v = -90 km/h \cdot \frac{1000 m/km}{3600 s/h}=-25 m/s

So the magnitude of the impulse of car 2 is

I_2 = (1200)(25)=30,000 kg m/s

So, car 2 exerts a larger impulse, therefore its impact is more violent.

A grapefruit falls from a tree and hits the ground 0.72 s later. How far did the grapefruit drop?
ycow [4]

Answer: 2.541884 meters

Explain:

Formula: s = 0.5 * g * t^2

Time of fall (t) is 0.72 while the gravitational acceleration rate is (9.80665m/s^2).
