The appropriate term for each statement is as follows;

Weight is the force on an object due to the gravitational attraction between it and the Earth (or whatever astronomical object it is primarily influenced by).

Mass, on the other hand, is a quantity of matter cohering together so as to make one body, or an aggregation of particles or things which collectively make one body or quantity.

Weight is measured in Newton's because it is a force while mass is measured in kilograms. The weight is affected by the gravity of the planet the object exists.

Answer:

14, 85 J

Explanation:

The formula of potential Energy (P.E.) is

P.E. = m * g * h, where m is the mass in kilograms, g is the acceleration due to gravity (about 10 m / \(s^{2}\) at the surface of the earth) and h is the height in meters.

Here P.E. is 0,55 kg * 10 m/s * 2,7 m = 14, 85 J

Answer:

-5.86secs

Explanation:

Using the equation of motion;

vy (final) = vy(initial) + gt

Substitute

0.0 = 57.45 + 9.81t

-57.45 = 9.81t

t = -57.45/9.81

t = -5.86secs

Hence the value of t is  -5.86secs

The value of t will be 5.86 seconds

when a body is thrown upward with an initial velocity \(v_{y}(initial)\) the equation on motion is written as:

          \(v_{y}(final)= v_{y}(initial)-gt\)

where g is the acceleration due to gravity which is 9.8 m/\(s^{2}\) acting opposite to the direction of motion and t is the time taken

          \(v_{y}(final)- v_{y}(initial)=-gt\)

         ⇒ \(0-57.45=-9.8t\)

         ⇒ t = 57.45/9.8

           t = 5.86 s

The step where light waves bounce off an object and move through the cornea, pupil, and lens corresponds to the first step in the four-step process of sensation and perception.

The four-step process of sensation and perception involves the following steps: stimulation, transduction, transmission, and interpretation. In the context of vision, the process begins with the stimulation of light waves bouncing off an object. This stimulation occurs when light waves from the object enter the eye.

The light waves first pass through the cornea, which is the transparent outer covering of the eye. Then they enter the pupil, which is the adjustable opening in the center of the iris. The iris controls the size of the pupil, regulating the amount of light that enters the eye. After passing through the pupil, the light waves reach the lens, which further focuses the light onto the retina at the back of the eye.

This initial step of the light waves moving through the cornea, pupil, and lens represents the process of stimulation in the sensation and perception cycle. It involves the physical interaction of light with the eye's structures, setting the stage for further processing and interpretation of visual information.

The minimum heat capacity is used in max possible heat transfer expression while defining the effectiveness of a heat exchanger because a fluid with a higher heat capacity rate will have a smaller temperature shift than a fluid with a lower heat capacity rate will.

According to the NTU approach, heat exchanger effectiveness is defined as the difference between the actual and maximum heat transfer rates.

The difference between the temperatures of the two entering streams would represent the highest potential temperature increase.

Now, heat capacity rate x temperature differential gives the rate of heat transfer. You should be aware that in this case, a fluid with a higher heat capacity rate will have a smaller temperature shift than a fluid with a lower heat capacity rate will.

The maximum possible heat transfer rate is then determined by multiplying the maximum temperature rise by the minimum heat capacity rate.

Radiation energy from the sun received at the earth's poles is less than that received at the equator, leading to winds that move heat towards the poles.

The Radiation energy from the sun is received to a lesser extent on the poles than it is received on the equator. This causes winds that move heat toward the poles. The equator receives the most direct amount of light as compared to the poles because of the angles between the equator and the sun.

The temperature is warmer near the equator whereas as you move toward the poles, the temperature is comparatively cooler because that area gets lesser sunlight. So, the number of sunlight decreases as we go away from the equator

Electromagnetic waves consists of alternate electrical and magnetic fields.

Light is a electromagnetic wave. Hence in light wave, electrical and magnetic fields vibrate.

In order to answer your question, we need to understand the concept of electric potential energy. When a charged object is brought closer to another charged object, the electric potential energy of the system changes. If positive work is required to bring the charged balloon toward the negatively charged sphere, it means that the electric potential energy of the system is increasing.

The electric potential energy of a charged object depends on both the charge and the distance between the objects. If the charged balloon has a negative charge, it would be attracted to the negatively charged sphere, and would not require any positive work to bring it closer. Therefore, we can conclude that the charge on the balloon must be positive.

If you must do positive work to bring a charged balloon toward a negatively charged sphere, the charge on the balloon is positive. This is because positive work indicates that you are working against an attractive force between the objects, which occurs when both objects have opposite charges (positive balloon and negative sphere).

The work done in pumping all the liquid out of the tank is 2500π lb-ft.

The potential energy of an object is given by the formula:

PE = mgh

Given:

Density of oil = 50 lb/ft^3

Diameter of the tank = 10 ft ( r = 5 ft)

To calculate the work done, we need to find the mass of the oil and the height it is lifted. Let's start by finding the mass:

Volume of oil in the tank:

The volume of a hemisphere = (2/3) * π * (r^3)

Volume = (2/3) * π * (5^3) = (2/3) * π * 125 = 250π/3 ft^3

Mass of the oil:

Mass = Volume * Density = (250π/3) * 50 lb

Now, we need to find the height of the tank. For a hemisphere, the height is equal to the radius (5 ft).

Finally, we can calculate the work done:

Work = PE = mgh = (250π/3) * 50 lb * 5 ft

Work = (250π/3) * 50 * 5 lb-ft

       = 2500π lb-ft

So, the work done in pumping all the liquid out of the tank is approximately 2500π lb-ft.

The work done on the car is the product of force and displacement. The work done by the force of 3N for a displacement of 3 m is 6 J.

Work done is the physical quantity that describes effectives of force in changing the motion of an object. When a force applied on an object results in a displacement, the force is said to be work done on the body.

Like force, work done is a vector quantity having both magnitude and direction. Thus work done can have both positive and negative values.

Work done is the dot product of force and displacement.

W = F .ds

Answer:

Because the Earth is EXTREMELY massive

Explanation:

Voltage drop across any components in series is proportional to its resistance. 60W bulb has higher resistance than 100W bulb if both the bulbs were rated for same voltage. So higher voltage drop will be across a 60W bulb.

In parallel voltage drops will be same across both the bulbs but current through it will be inversely proportional to the resistance. So 100W bulb draws more current than 60W bulbs.

60W dissipates more energy than 100W bulbs when in series and 100W bulbs dissipates more energy when in parallel.

Answer:

I think deposition of C is the oldest deposit

The cook needs to add 13,376,000 Joules of heat to raise 400 grams of water from 20 °C to its boiling point of 100 °C

To calculate the amount of heat the cook needs to add to the water, we can use the formula:

Q = m * c * ΔT

Where:

Q is the amount of heat (in Joules),

m is the mass of the water (in grams),

c is the specific heat capacity of water (in J/g °C), and

ΔT is the change in temperature (in °C).

Given:

Mass of water, m = 400 g

Specific heat capacity of water, c = 4186 J/g °C

Change in temperature, ΔT = 100 °C - 20 °C = 80 °C

Now, we can substitute these values into the formula:

Q = 400 g * 4186 J/g °C * 80 °C

Calculating the equation:

Q = 13,376,000 J

Therefore, the cook needs to add approximately 13,376,000 Joules of heat to raise 400 grams of water from 20 °C to its boiling point of 100 °C.

The specific heat capacity of water (4186 J/g °C) indicates that water requires a substantial amount of heat to raise its temperature. This is due to water's high specific heat capacity, which means it can absorb and retain a significant amount of heat energy compared to other substances.
