Answer:

Spaceship speed is 36000 km/h

So, in 1 hour spaceship travel 36000 km

Or we can say that in 60×60 second spaceship travel 36000 km

Therefore in 1 sec spaceship travel

=

= 10 km/s

Answer:

Explanation:

360 km/hr(1000 m/km) / 3600 s/hr) = 100 m/s

jok3333 [9.3K]

Answer

hawk maintains a consistent internal temperature in both the heat of the day and the cool of night this is called as endothermy.

Endothermy also known as warm-bloodedness is defined as the ability of an animal, bird or organism to produce heat and conserve it to maintain a consistent internal temperature.

If the temperature of a gas is increased by 10x, what will happen to the volume?
xxMikexx [17]

The volume of a gas will increase by ten times if the temperature is increased by ten times.

<h3>Relationship between the volume of a gas and temperature</h3>

The relationship between the volume of a gas and its temperature is explained in Charles' law of gases which states that:

  • The volume of a fixed mass of gas is directly proportional to its temperature provided the pressure of the gas is kept constant.

This means that if the temperature of a gas is increased by any given factor, the volume increases by the same factor proportionally.

Therefore, if the volume of a gas will increase by ten times if the temperature is increased by ten times.

Astronaut Mark Kelly and his crew traveled to the International Space Station in the space shuttle. The shuttle burned off all r
Nitella [24]

A couple of things, if the shuttle burned all of it's fuel before entering Earth's atmosphere then that means that the shuttle was accelerating towards Earth until it ran out of fuel.  At that point, there is little to no air resistance (friction) by the lack of an atmosphere so it keeps accelerating  due to Earth's gravitational force.  The closer the shuttle gets to Earth the stronger the gravitational pull the shuttle experiences.  Note that, once the shuttle reaches Earth's atmosphere it will cause significant amount of friction and thus will cause the shuttle to slow down.

Exoplanets (planets outside our solar system) are an active area of modern research. Suppose astronomers find such a planet that
Leno4ka [110]

Answer:

8.829 m/s²

Explanation:

M = Mass of Earth

m = Mass of Exoplanet

g_e = Acceleration due to gravity on Earth = 9.81 m/s²

g = Acceleration due to gravity on Exoplanet

m=M-0.1M\\\Rightarrow m=0.9M

g_e=G\frac{M}{r^2}

g=G\frac{0.9M}{r^2}

Dividing the equations we get

\frac{g}{g_e}=\frac{G\frac{0.9M}{r^2}}{G\frac{M}{r^2}}\\\Rightarrow \frac{g}{g_e}=0.9\\\Rightarrow g=0.9g_e\\\Rightarrow g=0.9\times 9.81\\\Rightarrow g=8.829\ m/s^2

Acceleration due to gravity on the surface of the Exoplanet is 8.829 m/s²
