Answer:

False, because A space probe is any unmanned spacecraft designed to carry out physical studies of the Moon, other planets, or outer space. Space probes take pictures, measure atmospheric conditions, and collect soil samples then bring or report the data back to Earth.A probe is a spacecraft that travels through space to collect science information. Probes do not have astronauts. Probes send data back to Earth for scientists to study. Sputnik 1 was the first probe to go into space.

Which layer of a tropical rainforest receives the least sunlight?

Nataly [62]

A topical rainforest is characterized by very tall trees which compete for light with each other. This means that the higher a layer is, the bigger chance it has for sunlight. All levels of canopy are quite high- so they still receive some sunlight.

The correct answer is the ground, which receives very little light

2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) de

Scrat [10]

Answer:

(d) increase by 100%

Explanation:

$m_{i}$ = initial mass of earth = m

$m_{f}$ = final mass of earth = (0.5) m

$R_{i}$ = initial radius of earth = R

$R_{f}$ = final radius of earth = (0.5) R

$g_{i}$ = initial acceleration due to gravity of earth = g

$g_{f}$ = final acceleration due to gravity of earth

initial acceleration due to gravity of earth is given as

$g_{i} = \frac{Gm_{i}}{R_{i}^{2}}$ Eq-1

Final acceleration due to gravity of earth is given as

$g_{f} = \frac{Gm_{f}}{R_{f}^{2}}$ Eq-2

Dividing eq-1 by eq-2

$\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}$

inserting the values

$\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}$

$g_{f}$ = 2 g

So there is 100% increase

e air pressure on Pikes Peak in Colorado is approximately 600 millibars. What is the relationship between air pressure at the to

faust18 [17]

Answer:

The pressure at the top of Pikes Peak is much lower (only about 60% that at sea level).

Explanation:

Atmospheric pressure decreases with altitude. The higher a location is in the mountains, the lower the atmospheric pressure will be. Pressure continues to decrease until the boundary with outer space where there is no air pressure at all and the atmosphere officially ends. Mountain climbers that scale the highest peaks in the world must bring oxygen tanks because of the scarcity of air at the roof of the world.
