Answer:
Acceleration = 3.5 m.s⁻²
Explanation:
Definition:
The acceleration is rate of change of velocity of an object with respect to time.
Formula:
a = Δv/Δt
a = acceleration
Δv = change in velocity
Δt = change in time
Units:
The unit of acceleration is m.s⁻².
Acceleration can also be determine through following formula,
F = m × a
a = F/m
Given data:
Force = 35 N (N = Kg. m.s⁻²)
Mass = 10.0 Kg
a = ?
Formula:
a = F/m
a = 35 Kg. m.s⁻²/ 10.0 Kg
a = 3.5 m.s⁻²
Answer:
A. The kinetic molecular theory relates the properties of a state of matter to the motion of its molecules.
Explanation:
The higher the kinetic energy of the molecules, the faster its movement will be. The state of a matter will depend on how fast the molecules move. When the molecules barely move, it will be packed tightly and its state will be solid. If the molecules kinetic energy rises, eventually they start moving around and the state will be liquid. If the kinetic energy rises further, the molecule will expand and changed into gas form.
Answer:
The answer to your question is: Arrhenius base
Explanation:
Arrhenius base ; an Arrhenius base is able to produce (OH-) in water, so Ca(OH)2 is an Arrhenius base.
Brønsted-Lowry base
. An Bronsted and Lowry base is able to accept a proton, Ca(OH)2 can do it.
Lewis base
this base is able to donate a pair of electrons, Ca(OH)2 does not have a pair of electrons to donate.
All of the above. This option is wrong only the first option is correct.
The mass would be 2 hydrogen electroydtyetes
