Answer:

Either Answer you Put is fine i put one as an answer and the other is the sample response and got it right.

My Answer: rather than typical sea floor rock, which had been shocked, melted, and ejected to the surface in minutes, and evidence of colossal seawater movement directly afterwards from sand deposits. Crucially the cores also showed a near complete absence of gypsum, a sulfate-containing rock, which would have been vaporized and dispersed as an aerosol into the atmosphere, confirming the presence of a probable link between the impact and global longer-term effects on the climate and food chain.

Sample Response:

Samples from the Western Hemisphere contained significantly higher amounts of shock-fractured quartz. This led Walter and Luis Alvarez to hypothesize that the asteroid impact site was in the Western Hemisphere.

zaharov [31]

Answer:

Explanation:

Given

launch velocity $u=100\ m/s$

Launch angle $\theta =30^{\circ}$

Range of Projectile $R=\frac{u^2\sin 2\theta }{g}$

$R=\frac{100^2\times \sin (2\times30)}{9.8}$

$R=883.699\approx 883.7$

Horizontal velocity remain same and only vertical velocity changes.

Initially vertical velocity is in upward direction but as soon as it reaches the ground its direction change but magnitude remain same.

$u_y=100\sin (30)=50\ m/s$

$u_x=100\cos (30)=86.60\ m/s$

$u_{net}=\sqrt{(50)^2+(86.60)^2}$

$u_{net}=99.99\approx 100\ m/s$

Which term means the distance between two bridge supports?

Ad libitum [116K]

The best answer is b - span.

A span is the distance between two bridge supports The supports may be towers, columns, or even the wall of a canyon.

There are many kinds of bridges but they all fall into three types namely beam, arch and suspension. The major difference between these three kinds of bridges is the distance that each can cross in a single span.

For example, a modern beam bridge is likely to span a distance of 200 feet, a modern arch can span 800 or 1000feet, and a modern suspension bridge can span up to 7000ft.
