Answer False
Explanation: Friction makes it stop at some point. For it to have an unlimited speed goes against beset is first law that states an object in motion with stay in motion unless acted upon by an external force, your force will be the friction of the wheels on the roller coaster

Answer:
The illustration represents the mitochondria of the cells.
Explanation:
The image shows the structure of a mitochondrion, whose shape is "ovoid", which contains two membranes, a folded inner and a smooth outer, observing invaginations (mitochondrial ridges). This article contains the enzymes for the Krebs cycle, oxidative phosphorylation being responsible for the energy generator for the maintenance of cellular activity.

Explanation:
Part A
Boiling point of HF is much higher as compared to the boiling point of HCl.
Reason:
The strongest inter molecular hydrogen bonding exist between HF molecules This is due to highly electronegative Fluorine atom.
Part B
The type of bonding present in the given compounds are:
1. Ice
The water molecules in ice are linked to each other through intermolecular hydrogen bonding due to the presence of electronegative oxygen atom that is attached to hydrogen atom.
2. Copper dioxide
In Copper dioxide, Copper and oxide ions are linked to each other via electrostatic force of attraction due to the presence of electronegative Oxygen atom and electropositive Cu atom.
Therefore, ionic bond is present in it.
3. Steel
In steel, metal and negatively charged electrons are linked to each other, thus giving rise to metallic bond between steel molecules.
4. Silicon elastomer
In silicon elastomer, Silicon atom is linked to other atom via covalent bonds due to sharing of electrons.
5. Tungsten
In the case of tungsten also, atoms are bonded to each other via metallic bond.
