Before giving you the answer straight away, I’d like to make sure you understand each option.

FIRST OPTION

“He developed the three laws of motion."

This option is not only the incorrect answer, but it is an incorrect statement. Galileo did not develop the three laws of motion. Isaac Newton was the one to compiled the three laws of motion.

SECOND OPTION

“He was the first to systematically study force and motion."

This option is a statement is true, and it could also be the correct answer. Galileo Galilei used experiments to search for the cause of motion.

THIRD OPTION

“He was the first to discover gravity."

This option is not only the incorrect answer, but it is an incorrect statement. Galileo was not the person to discover gravity. Sir Isaac Newton was the first to discover gravity.

FINAL OPTION

“He improved on Newton's laws."

This option is not only the incorrect answer, but it is an incorrect statement. Galilei did not improve Sir Isaac Newton’s laws.

Now that we’ve gone through each of the options individually, we can go ahead and determine the correct answer to the question, which is…

B ) He was the first to systematically study force and motion.

Kilauea is the most active shield volcano in the world. The volcano has erupted nonstop since 1983 and it is part of the Hawaiia

WARRIOR [948]

C) a volcanic hot spot.

Explanation:

Both the volcano and the seamount chain are thought to be the result of a volcanic hot-spot.

The Hawaiian -Emperor seamount chain and the active Kilauea shield volcano all formed due to an active volcanic hot spot.

A volcanic hotspot is a magma plume that is directly fed from the mantle. As the crust riding it moves, the hotspot remains at spot.

This feeding hotspot produce series of linear or patterned volcanic body as the riding plate moves on top of it.

This what is in play in the Hawaiian region.

Dashun Mack: Attempt

Montano1993 [528]

The time elapsed when the ball reaches the window is 1.55s

As per the question:

Final velocity, v = 11 m/s

Height, h = 29m

Acceleration, a = g = -9.8 m/s

From the third equation of motion:

v² = u² +2as

u² = v² - 2as

u² = (11)² - 2 × (-9.8) × (29)

u² = 689.4

u = √689.4

u = 26.25 m/s

Now, from the first equation of motion:

v = u + at

$t=\frac{v-u}{-g}$

$t = \frac{11 -26.25}{-9.8}$

t = 1.55 s

Therefore, the time elapsed when the ball reaches the window is 1.55s.

What is the approximate size of the smallest object on the Earth that astronauts can resolve by eye when they are orbiting 250 k

sesenic [268]

Answer:

the approximate size of the smallest object on the Earth that astronauts can resolve by eye when they are orbiting 250 km above the Earth is y = 31.495 m

Explanation:

Using Rayleigh criterion for the limiting angle of resolution of an eye

$\theta = \frac{1.22\lambda }{D } \\ \\ \theta = \frac{1.22*506 *10^{-9} }{4.90*10^{-3}m}$

$\theta = 1.2598*10^{-4}$ rad

$\theta = 125.98*10^{-6} \ rad$

Thus; the separation between the two sources is expressed as:

$\theta = \frac{y}{L} \\ \\ y = L \theta \\ \\ y = (250*10^3 )(125.98*10^{-6} \ rad) \\ \\ y = 31.495 \ m$

Thus; the approximate size of the smallest object on the Earth that astronauts can resolve by eye when they are orbiting 250 km above the Earth is y = 31.495 m
