PLZ HELP ON TIMER WILL GIVE BRAINLIEST

Chemistry
1 answer:
sergeinik [125]3 years ago
3 0

Answer:

I would put the final answer choice: "Scientists must first develop certain technologies before missions can be completed"

Explanation:

The first option is partially true, but we have ways around it.

The second option is straight-up false.

The third option doesn't make much sense, how can one work with technology that will be developed in the future and doesn't yet exist?

Therefore, the fourth option is the best.

Hope this helps

What happened to a balloon when it is put in freezer
e-lub [12.9K]

The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

Why are phase changes horizontal on a heating curve
Marta_Voda [28]

Answer:

A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes.The second change of phase is boiling, as the temperature stays the same during the transition to gas.

Water is a polar molecule, meaning the electrons that are shared between the atoms aren't shared equally so oxygen attracts more
amm1812

Answer:

Magnet with a positive and a negative pole

Explanation:

A great analogy to demonstrate what a polar molecule looks like is to imagine a magnet. A magnet has one positively charged end and one negatively charged end, two poles, that is.

Imagine that we have a magnet of a shape of a prism (water molecule has a bent shape). The two base vertices of the face of the triangle are positively charged, that's because hydrogen is less electronegative than oxygen and, hence, the two hydrogen atoms are partially positively charged in a water molecule.

Oxygen is more electronegative than hydrogen meaning it has a greater electron-withdrawing force, so electrons are closer to oxygen within the O-H bonds. Oxygen, as a result, becomes partially negatively charged, so it's our negative pole of the magnet.

Suppose an object is moving through space in a straight line. What could cause the object to start moving in a circle?
MAVERICK [17]
It could pass by a large enough object that has enough gravity to pull the object into its orbit and the object would stay in orbit because it has centripetal force.
