How can people take picture fpr black hole?
Jet001 [13]

We actually cant, really. Black Holes are really very powerful and don't just happen in some random place in the cosmos. We have got shots of Black holes that you cannot even see, but all the other big black holes that look like something straight of a sci-fi movie that look real, are really just photo- shopped. good question. Hope This Helped.

Igneous rock can be changed into which type of rock through the application of heat and pressure?
marin [14]

Answer:

metamorphic rock

Explanation:

Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.

Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.

  • At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks.
  • These changed rocks have different mineral facies that are different from those of the prolith.

Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.

A spaceship ferrying workers to moon Base i takes a straight-line pat from the earth to the moon, a distance of 384,000km, Suppo
GrogVix [38]

Answer:

95.78125%

18000 m/s

22233.33 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

v=u+at\\\Rightarrow v=0+20\times 15\times 60\\\Rightarrow v=18000\ m/s

The velocity of the rocket at the end of the first 15 minutes is 18000 m/s which is the maximum speed of the rocket in the complete journey.

Distance traveled while speeding up

s=ut+\dfrac{1}{2}at^2\\\Rightarrow s=0\times t+\dfrac{1}{2}\times 20\times 900^2\\\Rightarrow s=8100000\ m

Distance traveled while slowing down

s=18000\times 900+\dfrac{1}{2}\times -20\times 900^2\\\Rightarrow s=8100000\ m

Distance traveled during constant speed

384000000-(2\times 8100000)=367800000\ m

Fraction

\dfrac{367800000}{384000000}\times 100=95.78125\ \%

Fraction of the total distance is traveled at constant speed is 95.78125%

Time taken at constant speed

t=\dfrac{367800000}{18000}=20433.33\ s

Total time taken is 900+20433.33+900=22233.33\ s

Can someone answer this.
klemol [59]

Take left to be the negative direction, and right to be positive. That means the forces on the squirrel would be -2N and 3N.

Add all the forces to find the net force on the squirrel. -2N+3N=1N

Because the positive direction is to the right, the net force of 1N is directed to the right.
