Answer: 3 H
An acid consists of a hydrogen {positive radical} and a halogen or negative radical. When it is dissolved in water, the ionic bond is broken and ions are separated. The free H+ radical gets attracted to Hydrogen of water H2O and so it forms H3O+. The ionic bond gets weaker in water as electromagnetic forces are weak in water as water is dielectric medium.
Answer:
With all of that information, he's telling us the train's VELOCITY.
Explanation:
Velocity is a vector quantity made of two parts: speed and direction.
Answer:
Displacement method of volume measurement is no suitable
Explanation:
Displacement method of volume measurement is no suitable for the objects that do not get immersed into the water completely because of the hindrance in accuracy of the measurement.
Answer:
F = 32.2m
Explanation:
The force of gravity on an object is given by:
where
m is the mass of the object
g is the acceleration due to gravity
Here we have:
- An object of mass m
- The acceleration of gravity is expressed as
Therefore, substituting into the formula above, we find that the force of gravity on the object is
