In this problem, you’re given a mass (m) and a force (F) applied to an object and you’re asked to calculate the acceleration (a). If we plug this into the provided equation:
F = ma
(7.3 N) = (3.2 kg)a
a = 2.3 m/s/s
The acceleration of the object is 2.3 m/s/s.
Hope this helps!
A solute dissolves in excess solvent to form a solution:
solute + solvent → solution
<h3>What is the Enthalpy and their relation ? </h3>
A thermodynamic system's enthalpy, which is one of its properties, is calculated by adding the system's internal energy to the product of its pressure and volume. It is a state function that is frequently employed in measurements of chemical, biological, and physical systems at constant pressure, which the sizable surrounding environment conveniently provides.
A solution is a uniform mixture of two or more components that can exist in the solid, liquid, or gas phases. The amount of heat that is released or absorbed during the dissolving process is known as the enthalpy change of solution (at constant pressure).
There are two possible values for this enthalpy of solution ( H solution ) : positive (endothermic) and negative (exothermic). It is most straightforward to visualize a hypothetical three-step process occurring between two substances while trying to grasp the enthalpy of solution. The solute is one substance; let's call it A. The solvent is the second component; let's call it B.
The initial procedure exclusively affects the solute A and calls for disabling all intramolecular forces holding it together. This indicates that the molecules of the solute separate. This process' enthalpy is known as H1. Since breaking interactions requires energy, this is always an endothermic process, hence H1>0.
Their sign will be opposite.

A nuclear reaction must always conserve mass. Since natural transmutation includes the conversation of mass, it is a type of nuclear reaction.
Final answer:- <span>(4) natural transmutation</span>
In the titration of acetic acid with a strong base NaOH, the concentration of acetic acid is determined using the volume and molar concentration of NaOH used for titrating the vinegar solution. NaOH and acetic acid react in 1:1 mole ratio.
When a drop of the strong base, dispensed from the buret sticks to the walls of the Erlenmeyer flask but is not washed into the flask containing vinegar, it means that the recorded value of NaOH dispensed will be higher than the actual value required for the titration. So, the reported moles of acetic acid calculated from the moles of NaOH used for the titration will be higher. So, the mass percent reported will be higher than the actual value.
Surface tension, property of a liquid surface displayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. Because of this property, certain insects can stand on the surface of water.
