Answer: 7.35 Joules (7.35J)

Explanation:

Gravitational potential energy is defined to be the "stored" energy in the gravitational field. Since the force of gravity is conservative, the reference point for our zero potential does not matter. For simplicity, the zero reference point will be the floor which the table is sitting on. Gravitational potential energy is denoted as a capital 'U' and is defined to be:

[tex]U=mgh[/tex]

The 'm' is the mass, the 'g' is the acceleration due to the gravitational field, and the 'h' is the vertical height from the reference point. Plugging in the given values, you get:

[tex]U=(0.5kg)(9.8m/s^2)(1.5m)[/tex]

[tex]U=7.35J[/tex]

The SI units for mass is always the kilogram. So, you need to convert the grams into kilograms using the conversion factor of 1000g = 1kg.

Explanation:

This is the formula for the change in distance (δx) of an object moving with constant acceleration (a) and initial velocity (v), one of the standard Equations of motion. To solve for t first rearrange

12at2+vt−δx=0

then apply the formula for solving a Quadratic equation if our equation is At2+Bt+C=0 then the solution is

t=−B±B2−4AC√2A,

here A=12a, B=v, C=−δx so plugging these in the formula gives

t=−v±✓v2−4(12a)(−δx)√2(12a) (Apply quandriatic equation)

simplifying

t=−v±v2+2aδx√a.

Note how there are two possible solutions one corresponding to the + and one to the -. Sometimes one of these will give a negative time, so you may want to eliminate that. Indeed if δx>0, v>0 and a>0 we only want the positive solution. In other cases you may want to consider both solutions, for instance if we thow a ball up in the air the initial velocity is positive and the acceleration is negative, it will pass a fixed height above your head twice, once on the way up and once on the way down.

Relationship between force and strength of electrical charge directly proportional whereas the relationship between force and distance is inversely proportional

The relationship between force and strength of electrical charge directly proportional to each other which means if one increases the other will automatically increases whereas the relationship between force and distance is inversely proportional which means that if one increases the other will decrease.

Doubling the strength of both charges at the same time affects the force between them because both charges are directly proportional to its force so we can conclude that relationship between force and strength of electrical charge directly proportional whereas the relationship between force and distance is inversely proportional.

Ohm's Law

Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I=V/R, where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
