Answer:

34.292 m/s

Explanation:

When plane dives the gravitational acceleration becomes 10 times extra i-e

acceleration a = g= 10g's=10 ×9.8= 98 m/sec2

radius of dive circle = 12 m

v= speed= ?

Using

a= \frac{v^{2} }{r}

==> v^{2} = a × r = 98 × 12 = 1176 (\frac{m}{s}) ^{2}

==> v= \sqrt{1176(\frac{m}{s} )^{2} }

==> v= 34.292 m/s

a stone is thrown vertically upwards with a velocity of 20 m per second what will be its velocity when it reaches a height of 10
TEA [102]

Answer:

Explanation:

Here's the info we have:

initial velocity is 20 m/s;

final velocity is our unknown;

displacement is -10.2 m; and

acceleration due to gravity is -9.8 m/s/s. Using the one-dimensional equation

v² = v₀² + 2aΔx and filling in accordingly to solve for v:

v=\sqrt{(20)^2+2(-9.8)(-10.2)}  Rounding to the correct number of sig fig's to simplify:

v=\sqrt{400+2.0*10^2} to get

v = \sqrt{600}=20\frac{m}{s} If you don't round like that, the velocity could be 24, or it could also be 24.5 depending on how your class is paying attention to sig figs or if you are at all.

So either 20 m/s or 24 m/s

How did the temperature structure of the solar nebula determine planetary composition?
STALIN [3.7K]

Explanation:

The temperature of the solar nebula was decreasing as it moved away from its center. Therefore, only heavy elements could condense in the inner solar system and terrestrial planets could not form with light elements, such as gases. In the outer solar system, the Jovian planets formed mostly with gases, since temperatures were too low to allow rocky compositions.
