explain the forces of that affect the soccer balls path.​

The collections of properties which contain only features that can be changed by a resultant force is: speed, shape and direction.

A resultant force refers to a total effective force that has both magnitude and direction, which is mainly obtained through the addition of two (2) or more forces.

Hence, a resultant force is a single force acting on an object or physical body and it is obtained by combining two (2) or more forces.

Generally, there are some properties that changes when a resultant force is applied on them and these include:

Answer:

See explanation

Explanation:

Given that;

q1 and q2 are the magnitudes of the two charges while r1 is the distance between the charges.

F1 =kq1q2/r1^2

Then,

F2 = kq1q2/(2r1)^2

F2 = kq1q2/4r1^2

So,

F2 = 1/4 F1

The force between the charges changes by a factor of 1/4.

Answer:

Explanation:

The increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

Thermal expansion is the property of the matter to change its shape, size, length, volume, density etc with change in the temperature.

The thermal expansion can be calculate as,

[tex]\Delta L=aL\Delta T[/tex]

Here, [tex]L[/tex] is the original length, [tex]\Delta T[/tex] is the change in the temperature and [tex]a[/tex] is the coefficient of the expansion.

Given information-

The change in the length of the aluminum mater-stick is 1.00 mm.

Let the initial size of the aluminium mater-stick is 1.00 m or 1000 mm . The thermal expansion coefficient of aluminium is [tex](2.4\times10^{-5})[/tex] per unit Kelvin.

Put the values in the above formula as,

[tex]1=(2.4\times10^{-5})\times 1000\times\Delta T[/tex]

Solve for temperature as,

[tex]\Delta T=\dfrac{1}{(2.4\times10^{-5})\times 1000} \\\Delta T=42K[/tex]

Hence the increase in temperature is needed to increase the length of an aluminum meter-stick by 1.0 mm is 42 K. The option 1 is the correct option.

Answer:

The wave velocity and the wavelength are related to the wave's frequency and period by vw=λT or vw=fλ. The time for one complete wave cycle is the period T. The number of waves per unit time is the frequency ƒ. The wave frequency and the period are inversely related to one another.

Explanation:

T = 1 / f is the formula to calculate the period of a wave.

The time it takes for two successive crests (one wavelength) to pass a specified point. The wave period is often referenced in seconds.

The calculation of period of wave is:

The formula for period is T = 1 / f ,

where "T" is period – the time it takes for one cycle to complete, and "f" is frequency.

To get period from frequency, first convert frequency from Hertz to 1/s.

Period refers to the time for something to happen and is measured in seconds/cycle.

In this case, there are 11 seconds per 33 vibrational cycles.

Thus the period is (11 s) / (33 cycles) = 0.33 seconds.

Therefore,

T = 1 / f is the formula to calculate the period of a wave.

Answer:The average Velocity of the atoms =582.73m/s

Explanation:

Given

Mole of neon gas = 1.00 mol

Temperature = 2°C changing to Kelvin becomes

2°C + 273.15 = 275.15K

Mass = 0.0202 kg

Using the equation that connects the Average kinetic energy with ideal gas equation we have that

Kinetic energy=3/2 nRt

1/2(mv^2) = 3/2 nRt

Where

M = mass,

V = volume.

R = gas constant(8.31 jK-1 mol-1,

t = temperature in Kelvin,

n = number of moles

Putting our known values, we have that

1/2(0.0202 × v^2) = 3/2 (1 × 8.31 × 275.15)

0.0101 v^2 = 3,429.745

v^2 = 3429.745 / 0.0101

v^2 = 339,578.713

v = √339578.713

v = 582.73m/s

Quantity is most closely related to the speed of gas particles is the temperature of the gas.

Specifically, the speed of the molecules in a gas is dependent on its temperature (the higher the temperature the faster the gas molecules move). Another way to think of it is that the temperature of a gas is a measure of the average kinetic energy of that gas.

"Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature)."

Remark

This is a conservation problem.

The momentum before impact = momentum after impact

momentum before

m = 0.04 kg

v = 300 m/s

momentum after

m = 0.5 kg + 0.04kg    That's the mass of the block and bullet

v = ?

Solution

0.04 * 300 = 0.54 * x

12 kg m/s   = 0.54 kg * x

12 / 0.54 = x

x = 22.22 m/s

Answer:

a = 3 m/s^2

Explanation:

Vi = 10 m/s

Vf = 40 m/s

t = 10 s

Plug those values into the following equation:

Vf = Vi + at

40 = 10 + 10a

---> a = 3 m/s^2

The car is traveling with an initial velocity of 10 m/s, a final velocity of 40 m/s in the time period of 10 seconds, then the acceleration of the car is 3 m/s².

Acceleration describes a change in an object's velocity. By accelerating, decelerating, or changing direction of motion, an object's velocity may change.

An apple falling to the ground, the moon orbiting the earth, and a car stopping at a set of traffic lights are a few examples of acceleration. With the aid of these illustrations, we may better see that acceleration occurs whenever a moving object modifies its direction, speed, or both.

The given values according to the question are,

Initial velocity, u = 10 m/s

Final velocity, v = 40 m/s and,

Time, t = 10 seconds.

Use the equation of motion to find the acceleration,

v = u + at

40 = 10 + (a)10

a = 30/10

a = 3 m/s².

Hence, the acceleration of the car is 3 m/s².

18kW

Explanation:

very LED bulb has a power rating in terms of Watt-hour. It gives the power consumption per hour. For e.g. a 100W light bulb consumes 100W of electricity per hour. If left 'on' for 10 hours, a 100W light bulb costs 1kW and 1 unit of electricity is burned. Because 1 unit = 1 Kw of electricity.

I calculated my electricity consumption in 1 hour with LED Bulb as follows-

LED Bulbs power rating- 15 watt

quantity- 1

No. of hours a day – 12

Wattage in 1 hour – 12(time) x 15(load) x 1(quantity) = 180W = .18kW

So consumption units of power with a LED Bulb consume in 1 hour= .18 Units (because 1 KW = 1 unit)

100W translates to 100 watts consumed in 1 hour. Assuming the printer consumes electrical energy at a steady rate, then: 100 ÷ 60 = 1.6667 watts per minute. 1.6667 ÷ 2 = 0.8333 watts consumed in 30 seconds.

A printer has power of 100 W, and it takes time of 30 seconds to print out the document, then the power consumed in 30 seconds will be 0.8333 W.

The quantity of energy moved or changed per unit of time is termed as power in physics. The watt, or one joule per second, is the unit of power in the International System of Units. Power is also referred to as activity in historical texts. A scalar quantity is power.

Power is connected to other factors; for instance, the power required to move a land vehicle is equivalent to the sum of the vehicle's velocity, traction force on its wheels, and aerodynamic drag.

Assuming the printer consumes electrical energy at a steady rate, then:

100 ÷ 60 = 1.6667 watts per minute.

Now, calculate the power consumed in 30 seconds,

1.6667 ÷ 2 = 0.8333 watts.

Therefore, the power consumed in 30 seconds will be 0.8333 watts.

Answer: At the antinodes of a standing wave, the wave is shaking very rapidly, causing those parts of the pizza to get hot. At the nodes, the wave is not shaking much at all, causing those parts of the pizza to stay cold."

Explanation:

antinodes vibrate and are the opposite of nodes which are stationary.

Some parts of the pizza are hot while others are still cold. Because the antinodes of a standing wave shake very quickly, causing the hot spots on the pizza to appear.

The fact that there are locations along the medium that appear to be standing still is a feature of every standing wave pattern.

The term "node" refers to these sites, which are also known as "points of no displacement." Other sites along the medium are subjected to vibrations with substantial positive and negative displacements.

During each vibrational cycle of the standing wave, these are the locations that experience the most displacement. These points are termed "antinodes" because they are the polar opposites of nodes.

The antinodes of a standing wave shake very quickly, causing the hot spots on the pizza to appear. The wave isn't moving very much at the nodes, therefore those areas of the pizza stay cold."

Hence some parts of the pizza are hot while others are still cold.
