Substances that give ions when dissolved in water are called electrolytes. They can be divided into acids, bases, and salts because they all give ions when dissolved in water. These solutions conduct electricity due to the mobility of the positive and negative ions, which are called cations and anions respectively.
Electrolytes are composed of free-moving Charged Particles, i.e. ions. When a PD is applied across the electrolytes, the +ve ions move towards the -ve terminal and gain electrons to become neutral atoms, the opposite happens with the -ve atoms. Electrolytes lose their conductivity over time since they liberate some of the constituents of the electrolyte as gases or metals that settle at the bottom.
Answer:
I know its not Oxygen (O2) because we need that gas to breath if not more of that gas! and i know its not helium because it is not very toxic and not a crisis in the world
Your answers are going to be B. and D.
have a nice day!
Answer:
5.77 s
Explanation:
From the question,
The total time travelled by the projectile = Time of flight (T)
T = 2usinθ/g............ Equation 1
Where T = Time of Flight of the projectile, u = Initial velocity, θ = Angle of projection to the horizontal, g = acceleration due to gravity
Given: u = 40 m/s, θ = 45°
Constant: g = 9.8 m/s²
Substitute these values into equation 1
T = 2(40)sin(45°)/9.8
T = 80sin(45°)/9.8
T = 80×0.7071/9.8
T = 5.77 s
The typical temperature vs time graph for the evaporation of a liquid will show that there is a direct relation between the temperature and the time. Just as the ordinary water evaporates only when heat is applied to it, then we can conclude that an increase in time will heat up the streams.
If the object is denser then the substance it's in, it will sink. If the object is less dense than the substance, it will float.
