3. A chemical symbol designates an element that belongs to the periodic table. A chemical formula combines two or more symbols and it represents a chemical compound.
4.A mixture is made of two or more substances—elements, compounds, or both—that are together in the same place but are not chemically combined. Example: vegetable soup!Mixtures differ from compounds intwo ways: Each substance in a mixturekeeps its individual properties.
5.filtration, evaporation, distillation, chromatography

Answer:
a 10 kg elephant moving at 1 m/s
Explanation:
because kinetic energy depend on how fast an object moves and also depend on the gravitational force which include the weight.
Answer:
B= 55.6×10^(-7) Tesla
Explanation:
B= μoI/(2πr)
B: magnetic field strength
μo: permeability of free space and is equal to 4π×10^(-7) T.m/A
r: distance from the wire
I : current in the wire
B= (4π×10^(-7)×125)/(2π×4.5)
B= 55.6×10^(-7) Tesla
Answer:

Explanation:
First of all, we need to calculate the total energy supplied to the calorimeter.
We know that:
V = 3.6 V is the voltage applied
I = 2.6 A is the current
So, the power delivered is

Then, this power is delivered for a time of
t = 350 s
Therefore, the energy supplied is

Finally, the change in temperature of an object is related to the energy supplied by

where in this problem:
E = 3276 J is the energy supplied
C is the heat capacity of the object
is the change in temperature
Solving for C, we find:
