Explain how it is possible for the smallest white dwarfs to be the most massive.

1 answer:

8 0

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.. The most massive stars, with eight times the mass of the sun or more, will never become white dwarfs. Instead, at the end of their lives, they will explode in a violent supernova, leaving behind a neutron star or black hole.

What are the directions of movement for the Sagittarius, frontal, transverse planes ?

Dima020 [189]

Answer:

Squats involve flexion (forward motion) and extension (backward on the way up), so would fit into the sagittal plane. Frontal plane motion would include leaning from left to right as in sidebends and lateral raises, or perhaps you might picture jumping jacks for a good image of movement along the frontal plane.

Answer:

average speed = 1.73m/s

average velocity = 3.33m/s

Explanation:

we'll find the average speed first

average speed = total distance / total time

his total distance is 300m + 100m

= 400m

and total time should be taken in seconds as you know

((2×60)+50) + 60s

= 230s

so let's divide,

400m/230s

1.73 m/s

next, mean velocity

that is,

mean velocity = final- initial displacement/time

we have to note displacement ( this is the distance between the initial point to final point) here

the displacement is 300-100

so, 200m

we already calculated total time

but that cant be taken here

230 - 170

is the original time to travel 200m

that is, 60s

so we divide

200/60

3.33m/s

What distance does a car travel as its speed changes from 0 to 20 m/s in 17 s at constant acceleration?

love history [14]

Since acceleration is constant

So the distance moved in constant acceleration will be given as

$d = \frac{v_f + v_i}{2} t$

as we know that

$v_f = 20 m/s$

$v_i = 0$

t = 17 s

so distance moved is given by

$d = \frac{0 + 20}{2}(17)$

$d = 170 m$

so distance moved will be 170 m
