Answer:
Explanation:
An acid has H as the metal as in HCl
A base has OH as the nonmetal. (so Ca(OH)^2 is a base)
A salt has neither.
Answer:
The associated SI unit of force and weight is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth's surface. However, in the US common units, the pound is the unit of force (and therefore weight). The pound is the widely used unit for commerce.
Force = mass x acceleration
25N = 0.40kg x acceleration
25N/0.40kg = acceleration
acceleration = 62.5 N/kg
N/kg is the equivalent of m/s²
So your acceleration is 62.5 meters per second squared
The second law of motion states that: the acceleration of an object is dependent upon two variables: - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object
<h3>Meaning of Motion</h3>
Motion can be defined as the process of changing position willingly or due to a force applied.
Motion can be seen in different forms and types depending on the object.
In conclusion, The second law of motion is used to deduce the formula for acceleration.
