<span>Mendeleev observed that tellurium has chemical properties like other elements in its group, and he did not know that neutrons cause the greater atomic mass is the most likely reason.</span>
The best transition between the four options presented to represent a time when water molecules are moving closer together would be A. Frost forms on a window pane.
The closest distance that the water molecules can do is when the water is in the state of being solid. It is known that the solid state of matter has the closest distance from molecule to molecule that when a molecule tries to move, the others move as well creating a vibration and thus producing heat in the process. When they are in a liquid state, they are quite far from each other. In a gas state, they really are far from each. This explains the difference in their characteristics.
Answer:
a. 0.01 C
b. dissipated to outside environment
Explanation:
Let the specific heat of copper be 0.3846 kJ/kg-K or 384.6 J/kg-C
(a)The original kinetic energy of the block is:

As 85% of this kinetic energy is converted to block internal heat energy, with specific heat we can calculate the rise in temperature:




(b) the remaining 15% energy would probably be dissipated to outside environment as heat energy
30 N can not be a possible answer for the magnitude of the resultant of these vectors.
<h3>Resultant vector</h3>
The term resultant vector refers to the result obtained when two or more vectors are combined in magnitude and direction. It is that singular vector that has the same effect in magnitude and direction as two or more vectors acting together.
The resultant vector can not be be obtained algebraically rather it must be obtained geometrically. Hence, 30 N can not be a possible answer for the magnitude of the resultant of these vectors.

Answer:
There are 4 exresise ;endurance, strength, balance, and flexibility. Each one has different benefits.
Explanation:
Endurance activities, often referred to as aerobic, increase your breathing and heart rates.
Your muscular strength can make a big difference. Strong muscles help you stay independent and make everyday activities feel easier, like getting up from a chair, climbing stairs, and carrying groceries.
Balance exercises help prevent falls, a common problem in older adults that can have serious consequences.
Stretching can improve your flexibility. Moving more freely will make it easier for you to reach down to tie your shoes or look over your shoulder when you back your car out of the driveway.
