If the sun were to vanish instantly would earth immediately fly out of its orbit explain why or why not

1 answer:

7 0

<span>Answer: No, because Einstein demonstrated that nothing can exceed the speed of light in a vacuum and for something to happen instantly over that distance would require that speed to be exceeded. If somehow the sun were to vanish, without explosive effects, an enormous gravity wave would begin travelling outward affecting the planets at the speed of light - thus taking about 8 minutes to reach earth. But that is irrelevant because the only way to remove all that matter would be total conversion of the mass to energy and that energy would totally destroy everything - after the same 8 minutes.

What are igneous intrusions and extrusions

spayn [35]

Igneous intrusions form when magma cools and solidifies before it can reach the surface. An extrusion consists of extrusive rock; which forms above the surface of the crust.

A 2.3 kg cart is rolling across a frictionless, horizontal track toward a 1.5 kg cart that is held initially at rest. The carts

4vir4ik [10]

Answer:

Part a)

$P = 7.5 kg m/s$

Part b)

$v = 3.26 m/s$

Explanation:

As we know that two carts are moving in opposite directions

so here total momentum of two carts must be given by vector subtraction

It is given as

$P = m_1\vec v_1 + m_2\vec v_2$

$P = (2.3)(4.5) + (1.5)(-1.9)$

$P = 7.5 kg m/s$

Now we know that total momentum of the system is conserved here as there is no external force on this system

so the speed of the first cart when second cart was at rest is given as

$P = m_1 v_1 + 0$

$7.5 = 2.3 v$

$v = 3.26 m/s$

PLEASE HELPPP!!! Where do you think our modern ideas about government came from?

Vadim26 [7]

Answer:

Our modern ideas about government were influenced by many different ideas and traditions. The biggest influence came from their British heritage. (Remember the colonists WERE British until the American Revolution!)
