Only neutral substances (like pure water) can have a pH of 7.
Answer:
a)
b)
c)
Explanation:
From the question we are told that
Magnetic field strength
Distance traveled
Mass
Resistance
Gravitational acceleration
Because of perpendicularity
a)
Generally the direction of the current will be given as
Because it opposes increases of magnetic flux
b)
Generally the equation for induced EMF is mathematically given as
Generally the equation for induced current is mathematically given as
c)
Generally the the equation for force F at terminal speed is mathematically given as
The halogens group, this is also the group that is highly reactive. The halogens form salts with group one.
Answer:
The gravitational force does change believe it or not, but the explanation for this is that the Earth's orbit is an oval (or circle) the closer it nears itself to the Sun. The Sun's gravitational pull pulls the Earth to it, bringing it closer and as it reaches the other side, let's call this L; When it reaches L, it becomes the same gravitational pull reset as A is, and another section over the Sun, lets call this M; and when it reaches M, its the same pull as B.
