Answer:

If there is a system of magnets being held in place, there is potential energy. When you let go, the potential energy converts to kinetic energy and the magnets move. Putting the system of magnets close together which creates an opposing force.

Explanation:

Magnets cause objects to have kinetic energy by the magnetic force present in the magnet.

Magnets is a material which has a strong magnetic field which attracts ferromagnetic substances such as nickle, iron etc.

When a ferromagnetic objects put near the magnet, the magnet attracts the object and causes the movement towards its direction.

Therefore, magnets cause objects to have kinetic energy by the magnetic force present in the magnet.

Answer:

The work done on the system can be accounted for by;

Both [tex]E_g[/tex] and [tex]E_{int}[/tex]

Explanation:

The speed of the crate = Constant

Therefore, the acceleration of the crate = 0 m/s²

The net force applied to the crate, [tex]F_{NET}[/tex] = 0

Therefore, the force of with which the crate is pulled = The force resisting the upward motion of the crate

However, we have;

The force resisting the upward motion of the crate = The weight of the crate + The frictional resistance of the ramp due to the surface contact between the ramp and the crate

The work done on the system = The energy to balance the resisting force = The weight of the crate × The height the crate is raised + The heat generated as internal energy to the system

The weight of the crate × The height the crate is raised = Gravitational Potential Energy = [tex]E_g[/tex]

The heat generated as internal energy to the system = [tex]E_{int}[/tex]

Therefore;

The work done on the system = [tex]E_g[/tex] + [tex]E_{int}[/tex].

Answer:

It measure the effort it takes for an object to move

Explanation:

Work done is the force applied to move a body through a particular distance.

It can also to be said to be a measure of the effort it takes for an object to move.

The unit of work done is in Joules.

 To find work done, we use the expression below:

       Work done  = Force x distance

Answer:

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

  point A runs 150m east,

   70m west

  100m east

                                       150m

                --------------------------------------------------------→

                                                                   70m

                                                         ←---------------------

The displacement of the athlete  = 150 - 80 + 100  = 180m to the east

According to the question,

Point A runs:

Now,

The displacement will be:

Answer:

75 kg.

Explanation:

From the question given above, the following data were obtained:

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

Kinetic energy (KE), mass (m) and velocity (v) of an object are related according to the following equation:

KE = ½mv²

With the above formula, we can obtain the mass of the object as illustrated below:

Kinetic energy (KE) = 937.5 J

Velocity (v) = 5 m/s

Mass (m) =?

KE = ½mv²

937.5 = ½ × m × 5²

937.5 = ½ × m × 25

937.5 = m × 12.5

Divide both side by 12.5

m = 937.5 / 12.5

m = 75 Kg

Therefore, the mass of the object is 75 Kg.

Answer:

Weight

Explanation:

WEIGHT - downward pull to the center of earth due to gravity

ACCELERATION - the rate of change of velocity

VELOCITY - rate of change if displacement in time

The major difference between the mass and weight is that mass of an object can never be zero but weight can be zero. The downward pull on an object due to gravity is called the weight. The correct option is B.

The measure of the force of gravity acting on a body is defined as the weight. Actually weight is a force and its SI unit is Newton (N). The weight of an object depends on the mass and acceleration due to gravity.

The formula used to calculate the weight is:

w = mg

m = Mass of an object

g = Acceleration due to gravity

Weight is found to be a vector quantity. Because it has both magnitude and direction. It is directed towards the center of the earth or other gravity well.

When objects fall to the ground, it is the gravity which accelerates them. So the force of gravity which pulls the object downward is called the weight.

Thus the correct option is B.

Answer:

A. Electric force acts at a distance.

Explanation:

"Electric force," just like gravitational force is a "non-contact force." This means that even at a distance, two objects with no physical contact will create movement with the help of electric force. This leads to the concept of "force fields or field force" that explains why a charge object alters the region surrounding it. Once an object enters the region, it immediately experiences its force. An example of this is holding out one's hand near a "Van de Graaff generator." The electric force compels the hair strands to stand up.

Answer:yes

Explanation:yes

Answer:

It is not correct.

The correct conversion is:

1030 KJ = 246.18 KCal.

Explanation:

To know if 1030 KJ is equivalent to 245 KCal, we shall convert 1030 kJ to kcal. This can be obtained as follow:

4.184 KJ = 1 KCal

Therefore,

1030 KJ = 1030 KJ × 1 KCal / 4.184 KJ

1030 KJ = 246.18 KCal.

Thus, 1030 KJ is equivalent to 246.18 KCal.

From the above calculation, we can see that:

1030 KJ ≠ 245 KCal

Rather,

1030 KJ = 246.18 KCal.

Answer:

separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.

Answer:

Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate.

The NGC 3603 region of space is shown below. It is a cloud of gas and dust. Stars are forming in this cloud. The NGC 3603 be classified as a nebula. The correct option is A.

A tiny, ball-shaped nebula is known as a planetary nebula. It generates an ionized gas that is luminous. Large and typically erratic clouds are produced by diffuse nebulae.

Due to their big stars, they typically form a cluster of stars. a cloud of gas in space that can be seen in the night sky as a vaguely discernible brilliant patch, as something black, or as a shadow against other luminous objects.

Dust and gases, primarily hydrogen and helium, make up nebulae. The mass of gas and dust eventually grows so large that it is forced to collapse by gravity. The material in the cloud's core heats up as a result of the collapse, and this hot core is the start of a star.

Therefore, the correct option is A. As a nebula.
