Answer:
A. It makes astronauts weightless.
Explanation:
Gravity does not make astronauts feel weightless. Astronauts are weightless because they are orbiting at the same rate as their shuttle.
Although the force of gravity weakens as one moves away from the earth surface, it does not mean that this force is absent in orbit
- Gravitational force has a constant acceleration value near the earth surface which is commonly known to be 9.8m/s².
- It is a force of attraction tending to hold and bind bodies together so far they have mass.
- This force keeps every thing from escaping space-ward from the earth surface.
No, bleach is not heterogeneous. Bleach is actually homogeneous.
Heterogeneous is if it the same throughout.
Homogeneous is if it is different (has chunks and clumps of different materials)
The correct answer is A: H3PO4
Answer:
.....different temperatures
Explanation:
heat is a form of energy that is transfered from a body of high temperature to a body of low temperature....Cannot happen if the two bodies have the same temperature(thermal equilibrium)
The two substances that are mostly likely examples of covalent bonding are Sucrose and Ethanol.
<h3 /><h3 /><h3>What is a covalent Bond?</h3>
- A covalent bond is a type of chemical bond that involves the sharing of pairs of electron between atoms.
Examples of compounds with covalent bond include the following;
- Distilled water
- Sucrose
- Ethanol
Olive oil is a mixture not a compound
Sodium Chloride & Potassium lodide are examples of ionic bond.
Thus, the two substances that are mostly likely examples of covalent bonding are Sucrose and Ethanol.
