The equation of 5m+4=7m+6 is equal to m=-1
Answer:
A
Explanation:
Protons are the ones which give rise to different elements, hence different elements have different chemical properties. Therefore, the two atoms must have different proton numbers.
The relative atomic mass of an atom is determined by the mass of the neutrons and the protons. The mass of the electrons are not included due to their negligible mass (1/1840).
Hence, due to the different proton masses, the masses of the neutrons will also differ to ensure that both atoms have the same relative atomic mass.
Answer:
B. That energy can only be converted between different forms
Explanation:
The law of conservation of energy implies that energy can only be converted between different forms but can neither be created nor destroyed.
Energy is the ability to do work. It is very important physical quantity that is essential to all life forms.
Energy according to the law of conservation of energy is not produced neither is it destroyed.
Energy is simply transformed from one form to another.
That both of them are warm....at a certain temputurature causing one to fell,cozy
Scientists can measure the height in
different units but problem could arise when they compare all the measurements.
That is the reason there is standard units for measurements.
<span>There may be error arises when an
American scientist is measuring the height of an object in inches and other Australian
scientist is measuring the height of same object in meters. Their data cannot
be compared because they are using different units to measure height.</span>
