Based on the time that the solar system takes to circle the center of the milky way, the length of time that the Tyrannosaurus rex dinosaurs lived is  0.291 galactic years ago.

<h3>How long ago did the Tyrannosaurus rex live?</h3>

The Tyrannosaurus rex lived 67 million years ago.

If a single galactic year is 230 million years then the Tyrannosaurus rex lived:

= Number of years ago  Tyrannosaurus rex lived / Number of years in galactic years

Solving gives:

= 67 / 230

= 0.291 galactic years ago

Full question is:

Galactic years. The time the Solar System takes to circle around the center of the Milky Way galaxy, a galactic year, is about 230My. In galactic years, how long ago did the Tyrannosaurus rex dinosaurs live?

Suppose the ring rotates once every 4.30 ss . If a rider's mass is 58.0 kgkg , with how much force does the ring push on her at
Stells [14]

Answer:

422.36 N

Explanation:

given,

time of rotation = 4.30 s

T = 4.30 s

Assuming the diameter of the ring equal to 16 m

radius, R = 8 m

v = \dfrac{2\pi R}{T}

v = \dfrac{2\pi\times 8}{4.30}

  v = 11.69 m/s

now, Force does the ring push on her at the top

- N - m g = \dfrac{-mv^2}{R}

N + m g = \dfrac{mv^2}{R}

N = \dfrac{mv^2}{R}- m g

N = m(\dfrac{v^2}{R}- g)

N = 58\times (\dfrac{11.69^2}{8}- 9.8)

N = 422.36 N

The force exerted by the ring to push her is equal to 422.36 N.

A 1.5kg cart moves along a track at 0.20m/s until it hits a fixed bumper at the end of the track. Find the average force exerted
DochEvi [55]

Answer:

Net force will be 4.875 N

Explanation:

We have given mass of the cart m = 1.5 kg

Initial velocity of the cart  = 0.2 m/sec

And final velocity of the car = - 0.125 m/sec ( Negative direction is due to opposite direction )

Instant of time \Delta t=0.1sec

Change in momentum is given by

\Delta P=1.5\times (0.2-(-0.125))=1.5\times 0.325=0.4875kgm/sec

Now force is given by

F=\frac{\Delta P}{\Delta t}=\frac{0.4875}{0.1}=4.875N

Net force will be 4.875 N
