C.NaCl as ionic compounds are made of a metal and a non-metal and they form oppositely charged ions hence the name ionic bonding which forms ionic compounds.The other are molecules with covalent bonding.
Answer:
(C) Independent variable
Explanation:
Independent is the variable used by the experimenter to vary a condition of interest in the experiment (temperature in this case). This measure is varied over a sensible range to induce changes in other aspects (dependent variables; level of aggression in this case) which are measured during the experiment.
1. Yes it is most likely that aliens exist because we have a whole universe yet to discover and us humans can’t be the only species alive
2. Blue light travels faster than any other color in the color prism and is scattered throughout more in the sky than other colors
3.
A denser liquid will sink to the bottom while a less denser liquid will float. Also, liquids composed of polar molecules such a water will not form chemical <span>bonds with nonpolar molecules.
Density.

Answer:
Tension in the cable is T = 16653.32 N
Explanation:
Give data:
Cross section Area A = 1.3 m^2
Drag coefficient CD = 1.2
Velocity V = 4.3 m/s
Angle made by cable with horizontal =30 degree
Density 
Drag force FD is given as
Drag force = 14422.2 N acting opposite to the motion
As cable made angle of 30 degree with horizontal thus horizontal component is take into action to calculate drag force
TCos30 = F_D
T = 16653.32 N
