Alondra applies 24 N of force to the end of a stick (a type of lever) to open a can of paint.
The lid resists with 6 N of force. What is the mechanical advantage?

Answers

Answer:

1/4

Explanation:

Mechanical Advantage = Load/Effort

Given

Effort applied = 24N

Load = 6N

Substitute

MA = 6/24

MA = 1/4

Hence the mechanical advantage is 1/4

Answer:

4

24n/6n=4

A wire has compasses placed around it and a current is passed through the wire. What happens to the compasses

Answers

Answer:

If you hold a compass near a wire through which current is flowing, the needle on the compass will be deflected. Since compasses work by pointing along magnetic field lines, this means that there must be a magnetic field near the wire through which the current is flowing

Motion is
displacement
an object you look at to determine if something is moving
a change of position in relation to another object
speed

Answers

Answer:

a change of position in relation to another object.

Explanation:

Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.

This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.

A reference point refers to a location or physical object from which the motion (movement) of another physical object or body can be determined.

Mathematically, the motion of an object is described in terms of acceleration, time, distance, speed, velocity, displacement, position, etc.

Hence, motion is a change of position in relation to another object.

You wake up in the morning and get out of bed. Does the floor feel cold or warm on your bare feet? On the lines below, write a sentence that compares how it feels to step on a bare floor and on a rug on a cold morning

Answers

When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn

We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.

What is heat transfer?

Heat will be transfer on a temperature gradient from one substance to the other.  Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.

Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum.  At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.

A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.

Answers:

1) A process that occurs when an object or a particle moves, referred to as kinetic energy

2) A potential energy is a stored amount of energy that changes depending on the relative positions.

3) Potential Energy is the energy stored in an object due to its position. Kinetic Energy is the energy of motion in a moving object.

  a) C and B

  b) A

  c) From B to A or from C to A

  d) From A to B or from A to C

[tex]\huge\mathfrak\green{answer}[/tex]

1) Kinetic energy of an object is the measure of the work an object can do by the virtue of its motion.

For Example : A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.

2) Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

For Example : A child at the top of the slide

3) KINETIC ENERGY

Kinetic energy is the kind of energy present in a body due to the property of its motionIt can be easily transferred from one body to anotherIt is relative with respect to natureFlowing water is one of the examples of kinetic energy

POTENTIAL ENERGY

Potential Energy is the type of energy present in a body due to the property of its stateIt is not transferableIt is non-relative with respect to natureWater present at the top of a hill is an example of potential energy

Hi people; there's a question that has been so confusing for me and a friend of mine.
0°C + 0°C = 64°F
Is this correct or wrong?

Answers

Answer:

The correct answer is: 0°C + 0°C = 32°F

Explanation:

We need to remember the conversion equation from Celsius to Fahrenheit:

[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]

In our case x = 0, then y will be:

[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]

[tex]y=32^{\circ}F[/tex]

Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.

Then, knowing that 0°C = 32°F we can conclude that:

[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour

Answers

Answer:

Hello your question is incomplete below is the missing piece

What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.

answer :  25.73 m/s

Explanation:

Given

V1 = 15 miles/hour =  6.71 m/s [ 45° EN ]

V2 = 18 m/s [ 5° NE ]

Calculate  the resultant velocity

Vr = 6.71 m/s[45°] + 18m/s[5°].

Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )

Vr = ( 4.74  + 4.74 i  )+  ( 17.93 + 1.57i) = 22.67 + 12.18i.

Therefore the magnitude

= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Its total power of an independent device stays constant underneath the Mass conservation on Energy and it is, the kinetic energy plus potential energy is just like a fixed [tex](KE+PE=Standard)[/tex]. So, if KE improves, it is valid that PE declines.

If the PE is now at least then KE has been at the highest. It is also valid that KE is reduced as PE is increased as well as the maximum PE, the minimum KE.

Answers

Answer: No , a chemical change has not occured as it was easily reversed.

Explanation:

Chemical change is defined as a change in which rearrangement of atoms take place and leads to formation of new substances. It can only be reversed with the help of a chemical reaction.

Physical change is defined as a change which leads to change in shape, size or state of the substance changes. No new substance is formed.It can be easily reversed.

As the hair colour was washed out and returned to its original brown colour, it was a physical change.

Answers

Answer:

Kindly check explanation

Explanation:

Motion of an object could be explainwd as how a body changes position over time. Some of the proven facts about motion are stated by Sor Isaac Newton, named the Laws of motion :

1. A body will continue on it's state of rest or uniform motion in a straight line unless acted upon by a force to make it act otherwise.

2.) The second law explains that the force acting in an object is a product of the mass and acceleration.

Force = mass * acceleration due to gravity

3.) To every action, there is an equal and opposite reaction.

That is ; applied force in the positive direction on an object, yield an equal amount of force in the opposite direction.
