6. What is the GPE of a 500g box of chocolates 2 m above the ground?

Answers

Answer 1
GPE = mgh
m = mass=500g = 0.5kg
h= height = 2m
g = gravitational field strength, 9.8 near surface of earth
therefore GPE = 0.5*9.8*2 ( 0.5*2=1 so they cancel out), GPE = 9.8J

A 5 kg rock is lifted 3 m above the ground. What is the rock's GPE now?
A. 15 J
B. 15,000 J
C. 1,500J
D. 150 J

Answers

gravitational potential energy (aka GPE or Ug) = mass*gravitational force*height

GPE=5*10*3= 150 J

Side-note: If you were to use a real-life scenario/accurate gravitational force, you would use 9.8 N.

So the most “accurate” equation would be 5*9.8*3=147 J, which is already roughly near 150 J.

7. A 500 g ball is about to roll off the edge of a 1. 5 m tall table. What is its current gravitational potential energy?

Answers

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.

If a 3 kg block rests on a rough horizontal table and experienced a 2 N force of static friction then what is the coefficient of static friction between the block and the table

Answers

The coefficient of static friction of the block is 0.068.

What is static friction?

This is the force between two bodies in contact and tends to oppose their motion. It is also the force that keeps two bodies at rest

To calculate the coefficient of static friction, we use the formula below.

Formula:

F = mgμ............. Equation 1

Where:

F = Horizontal forcem = mass of the blockg = acceleration due to gravityμ = coefficient of static friction.

Make μ the subject of the equation

μ = F/mg.............. Equation 2

From the question,

Given:

m = 3 kgg = 9.8 m/s²F = 2 N

Substitute these values into equation 2

μ = 2/(3×9.8)μ = 2/29.4μ = 0.068.

Hence, The coefficient of static friction of the block is 0.068.

Answers

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

Relationship between force, charges and distance

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.

rearrange the equation d=vt-1/2at^2 to find v

Answers

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.
