Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter. Magnets are attracted to and repel other magnets.

Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter. Magnets are attracted to and repel other magnets.

One of the four fundamental forces of nature, the electromagnetic force, results in the magnetic force, which is brought about by the motion of charges.

When two charge-containing objects move in the same direction, a magnetic attraction pulls them together. Similar to this, there is a repulsive force between charged objects travelling in opposing directions.

We discovered how moving charge envelops itself with a magnetic field in our essay on magnetic fields. The magnetic force in this sense is a force that results from interacting magnetic fields.

Therefore, Magnetic forces are non contact forces; they pull or push on objects without touching them. Magnets are only attracted to a few 'magnetic' metals and not all matter. Magnets are attracted to and repel other magnets.

The correct electromagnetic waves for the given applications are Diagnosing illnesses: Infrared waves, Warming and cooking food: Microwaves and Transmitting data from remote controls to televisions: Infrared waves

Let's elaborate on each application:

 1. Diagnosing illnesses: Infrared thermography, also known as thermal imaging, uses infrared waves to create an image of the body's heat distribution. This can reveal areas of increased heat, which may be indicative of inflammation, infection, or other conditions. Infrared waves are a part of the electromagnetic spectrum with wavelengths longer than visible light and can penetrate the skin to some extent, making them suitable for this application.

 2. Warming and cooking food: Microwaves are a form of non-ionizing electromagnetic radiation with wavelengths longer than those of infrared waves but shorter than radio waves. Microwave ovens use these waves to agitate water molecules in food, causing them to vibrate and generate heat, which cooks or warms the food. The frequency used in microwave ovens is specifically chosen to resonate with water molecules, making it efficient for heating.

 3. Transmitting data from remote controls to televisions: Infrared waves are used for short-range communication between devices like remote controls and televisions. The remote emits a beam of infrared light that is modulated to carry information, such as the command to change the channel or adjust the volume. The television's infrared receiver detects these signals and processes them accordingly. Infrared is chosen for this application because it is simple, reliable, and does not interfere with other electronic devices.

If all of Earth's polar ice melts, the global sea level and average global temperature would increase, while the area covered by ice in the polar regions would decrease.

If all of Earth's polar ice melts, several parts of the graph would increase. One part that would increase is the global sea level. As the ice melts, the water would contribute to higher sea levels. Another part that would increase is the average global temperature. The melting ice would release more greenhouse gases, which would further contribute to global warming. Hurricanes and extreme weather events would also increase in frequency and intensity.

On the other hand, the part of the graph that would decrease is the area covered by ice in the polar regions. With the melting of the polar ice, the ice extent would significantly shrink, leading to decreased ice coverage over the Arctic and Antarctic regions.

Final answer:

To calculate Brandon's mass with a weight of 600 newtons, we use the weight formula W = mg, where g is the gravitational acceleration (9.8 m/s²). Dividing the weight by g gives a mass of 61.2 kilograms.

Explanation:

The question asks to find Brandon's mass given that he weighs 600 newtons. To find the mass, we use the formula of weight which is the product of mass (m) and the acceleration due to gravity (g), stated as W = mg. Since the acceleration due to gravity is approximately 9.8 m/s² on Earth, we can rearrange the formula to solve for mass: m = W/g. Plugging in the known values we get m = 600 N / 9.8 m/s², which gives us approximately 61.2 kg.

Therefore, the correct answer is C. 61.2 kg.

Answer: 4

Explanation:

Given that:

Mass of car M = 2200 kg

Initial speed Vi = 50 km/hr

Final speed Vf = 100 km/hr

Kinetic energy is the energy possessed by a moving object. It is measured in joules, and depends on the mass (m) of the object and the speed (v) by which it moves

i.e K.E = 1/2MV^2

So, when traveling at 50 km/h

KE = 1/2x 2200kg x (50km/h)^2

KE = 0.5 x 2200 x 2500

KE1 = 2750000J

So, when traveling at 100 km/h

KE = 1/2x 2200 x (100 km/h)^2

KE = 0.5 x 2200 x 10000

KE2 = 11000000J

Thus, the number of times kinetic energy increases is obtained by dividing KE2 by KE1

i.e 11000000J / 2750000J

= 4

Thus, the kinetic energy from the car’s forward motion increase 4 times

Answer:4

Explanation:m=2200,u=50,v=100

The unit for speed is in m/s we have to conver to m/s

For ke1=50km/h to m/s 50×1000/3600=13.89

So keep=1/2mv^2

1/2(2200)13.89^2= 212225.31

Ke2=1/2mv^2=100×1000/3600=27.78

1/2mv^2= 1/2(2200)27.78^2

=848901.24 .....soke2/ke1 = 848901.24/212225.31=4

The force of about 5.47 kN will be exerted on the acrobat by the cannon.

Explanation:

If work is done on the system which is acrobat for the present case, then the ratio of work done to the distance of the contact force medium can give us the force exerted on the acrobat or system.

As here the cannon is the source of force and it has a barrel of 3.05 m that means the cannon ball should travel the distance of 3.05 m to reach the acrobat and it has done a work of about 16700 J to accelerate the cannon ball. So as per Newton's third law of motion, the force gained by the cannon ball due to the work done on it will be equal to the force exerted on the acrobat by the cannon.

Thus, as work done is the product of force with displacement. Here the force experienced by the cannon ball will be the ratio of work done to the distance covered by the cannon ball.

[tex]Force = \frac{Work done }{Distance} = \frac{16700}{3.05} = 5,475 N.[/tex]

So, the force experienced by the cannon ball is 5.47 kN and the same force will be exerted on the acrobat.

Thus, the force of about 5.47 kN will be exerted on the acrobat by the cannon.

Final answer:

To find the force exerted by the cannon on the acrobat, use the formula Work = Force × Distance. Substitute the given values and calculate the force to be 5475.41 Newtons.

Explanation:

Force exerted by the cannon on the acrobat:

To calculate the force exerted by the cannon on the acrobat, we use the formula Work = Force × Distance. Given that 16700 J of work is done to accelerate the acrobat over a distance of 3.05 m, we can find the force by dividing the work by the distance: Force = Work / Distance.

Substitute the values:

Calculate the force:

Force = 16700 J / 3.05 m = 5475.41 N

Therefore, the force exerted by the cannon on the acrobat is 5475.41 Newtons.

Answer: KE = 62.5J

Explanation:

Given that

Mass of object = 5kg

kinetic energy KE = ?

velocity of object = 5m/s

Since kinetic energy is the energy possessed by a moving object, and it depends on the mass (m) of the object and the velocity (v) by which it moves. Therefore, the object has kinetic energy.

i.e K.E = 1/2mv^2

KE = 1/2 x 5kg x (5m/s)^2

KE = 0.5 x 5 x 25

KE = 62.5J

Thus, the object has 62.5 joules of kinetic energy.

Answer:

0.833 J

Explanation:

The initial kinetic energy of the spike is:

KE = ½ mv²

KE = ½ (0.52 kg) (3.7 m/s)²

KE = 3.56 J

23.4% of this energy is converted to internal energy.

U = 0.234 (3.56 J)

U = 0.833 J

Answer: 0.01 m/s2

Explanation:

Given that:

Velocity of supertanker = 7.2 m/s (about 12 mph)

Time taken = 12 min

(Since the SI unit of time is seconds, convert 12 minutes to seconds

1 minute = 60 seconds

12 minutes = 12 x 60 = 720 seconds)

Average deceleration = ?

Recall that deceleration is obtained by dividing velocity by time taken.

i.e Deceleration = velocity / time

Deceleration = 7.2 m/s / 720 seconds

= 0.01 m/s2

Thus, the magnitude of its average deceleration is 0.01 meters per second squared.

Final answer:

Saturn, being one of the outer planets far from the Sun, has much colder surface temperatures compared to the inner planets like Venus, Mars, and Mercury, making it the most likely to have the coldest surface temperature among the options provided.

Explanation:

The planet most likely to have the coldest surface temperature among the options provided (Venus, Mars, Saturn, Mercury) is Saturn. Surface temperatures on planets decrease with increasing distance from the Sun because the planets are heated by the Sun's radiant energy, which diminishes with the square of the distance. Saturn, being far from the Sun, has much colder temperatures compared to the inner planets.

Furthermore, planets like Jupiter, Saturn, Uranus, and Neptune are giant gas planets with substantial distances from the Sun, leading to much lower surface temperatures. Given Saturn's greater distance from the Sun compared to Venus, Mars, and Mercury, it is the planet most likely to have the coldest surface temperature among the options.

Based on the given options, Mars is the planet most likely to have the coldest surface temperature.

To determine which planet most likely has the coldest surface temperature based on the given diagram and options provided, we can consider the distance of each planet from the Sun and its effect on surface temperature:

1. **Mercury**: Being closest to the Sun does not necessarily mean it has the hottest surface temperature. Despite its proximity, Mercury has extreme temperature variations due to its lack of atmosphere to retain heat.

2. **Venus**: While Venus is closer to the Sun than Earth, it has a thick atmosphere that traps heat, resulting in a very high surface temperature making it one of the hottest planets in our solar system.

3. **Mars**: Mars is farther from the Sun than Earth and has a thin atmosphere, which leads to colder surface temperatures compared to Venus and Earth. It experiences colder conditions due to its distance and atmospheric composition.

4. **Saturn**: Saturn is a gas giant planet, and its distance from the Sun results in very cold temperatures in its upper atmosphere. However, the question specifically asks about the surface temperature, and gas giants like Saturn do not have a solid surface to measure a surface temperature.

Based on the given options, **Mars** is the planet most likely to have the coldest surface temperature. It is farther from the Sun than Venus and has conditions more conducive to lower temperatures compared to the other listed planets.
