Answer: Yes, Because kinetic energy is proportional to the velocity squared, increases in velocity will have an exponentially greater effect on translational kinetic energy. Doubling the mass of an object will only double its kinetic energy, but doubling the velocity of the object will quadruple its velocity.
Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field.

Answer:
False
Explanation:
This equal distribution of electrons means that the molecule has no separate positive and negative areas (nonpolar). It has polar and nonpolar properties; has an ionic end that will dissolve in water and a long hydrocarbon portion that will dissolve in oily dirt.
Answer:
option B= Al, Ga and In
Explanation:
Properties of Boron group:
- These elements are belongs to boron group which is thirteen group of periodic table. There are six elements are in this group boron, aluminium, gallium, indium, thallium and nihonium.
- They are also called p-block elements because their valance electrons are present in p subshell.
- All these elements have three valance electrons.
- Boron is metalloid while other elements are metals.
- Their oxidation state is +3 because of tendency to lose three valance electrons and create positive charge.
- Their atomic sizes increases down the group with increase of atomic number.
- Their ionization energies decreases down the group because of increase of atomic radius and ease of removing of electrons.
Answer:
volume of the container will decreases if pressure increases.
Explanation:
According to Boyle's law:
Pressure is inversely proportional to volume which means if pressure of a gas increases the volume of the gas will decreases as gas molecules will collide and come closer forcefully so volume will decreases. And its formula for determining volume and pressure is:
<em>PV=nRT</em>
where "R" is a ideal gas constant
"T" is temperature and
"n" is number of particles given in moles while "V" is volume and "P" is pressure.
