Small robots that can move around on the surface of a planet are called space shuttles.
Luden [163]

No.  "Shuttle" has been pretty much used to indicate shuttling
between Earth and Earth-orbit. 

The devices that have tooled around on the surface of Mars
have been referred to as "rovers".  That was also the nickname
of the buggy on which the Apollo astronauts moved around on
the Moon in the early 1970s ... the "lunar rover".

A wrench 20 cm long lies along the positive y-axis and grips a bolt at the origin. A force is applied in the direction 0, 4, −3
Andreyy89

Answer:

1250 N

Explanation:

length of wrench = 20 cm = 0.2 m

Write the length of wrench in vector form

r = 0.2 j metre

Direction of force= \frac{0i+4j-3k}{\sqrt{0 + 16 + 9}}=\frac{0i+4j-3k}{5}

Let the magnitude of force is F

So, write the force in vector form

F = F  \frac{0i+4j-3k}{\sqrt{0 + 16 + 9}}=\frac{0i+4j-3k}{5}

torque, T = 150 Nm

Torque = T = r x F

150 i =0.2j\times F\frac{0i+4j-3k}{5}

F = 1250 N

Thus, the magnitude of force is 1250 N.

Why didn’t early Portuguese and Dutch explorers decide to create settlements in Australia
aleksandrvk [35]
I think it is because most of the settlements in Australia are under the Spanish rule. Aside from that, Australia was part of the Spanish territory because of the papal bull mandated by Pope Alexander VI. The papal bull divided the world between Spain and Portugal. Spain has full control of the west while Portugal owns the east side of the world

Portuguese explorers were forced to study Australia in secret.

Name the two types of vaporization and explain the difference between them. Give one example of each. ​
kolezko [41]
Evaporation and boiling.
Evaporation refers to only the surface level turning it into a gas and the vaporization pressure of the liquid remains low.
When a substance boils it’s pressure is high and the surface evaporated along with the rest of the liquid at an equal rate. A sign of boiling is the presence of bubbles, which occur only in the process of boiling and not in evaporation.
A example of boiling is heating water up to the point until you see steam and bubbles.
A example of evaporation is the melting of an ice cube.

PLEASE HELP! Explain how energy travels outward from the core and is emitted from the Sun. Include what happens in each layer of
xxMikexx [17]
Fusion occurs in the Sun's core, releasing energy that is transferred outward. Once in the radiative zone, gamma rays are transferred by radiation. They are converted to other types of photons, which move into the convective zone, where they are transferred by convection. Finally, energy is emitted from the photosphere.
