What is the velocity of a ball swung around on a rope with a
radius of 0.25 meters and period of 0.40 seconds?

Answer:

Noah has run 600 metres north east

Answer:

[tex]\boxed {\boxed {\sf 98 \ J}}[/tex]

Explanation:

We are asked to find the potential energy of a bowling ball.

Potential energy is the energy an object possesses due to its position. It is calculated using the following formula.

[tex]E_p= mgh[/tex]

In this formula, m is the mass, g is the acceleration due to gravity, and h is the height.

The bowling ball has a mass of 2 kilograms. The hill is 5 meters high. Assuming this situation is occurring on Earth, the acceleration due to gravity is 9.8 meters per second squared.

Substitute the values into the formula.

[tex]E_p= (2 \ kg )(9.8 \ m/s^2)(5 \ m)[/tex]

Multiply the numbers together.

[tex]E_p=19.6 \ kg*m/s^2(5 \ m)[/tex]

[tex]E_p=98 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule. Our answer of 98 kg*m²/s² is equal to 98 Joules.

[tex]E_p= 98 \ J[/tex]

The bowling ball has 98 Joules of potential energy.

Explanation:

Exoplanets are very hard to see directly with telescopes. They are hidden by the bright glare of the stars they orbit. So, astronomers use other ways to detect and study these distant planets.

Exoplanets are difficult to detect because they are a star 'wobbles' as it orbits the center of mass, changing the wavelength of light it emits.

Answer:

When the leftovers are left in the autumn, they have two purposes:

- Preventing erosion; the roots remain in the ground, so they hold it tightly till the next planting of the crops.

- Fertilizing the soil with natural material; the roots will not rot quickly in the colder period of the year, but will start rotting much faster in the spring, thus they will enrich the soil.

Answer:

Explanation:

Answer:

I think 32.00

Explanation:

Because the equation is mass times velocity so is you mutiply 32 by 25 and 28 times 25 sample A would be greater.

The sample with the greatest average kinetic energy is sample A

The average kinetic energy of a sample can be estimated by the formula one-half of the mass sample multiplied by the speed (RMS) squared.

Mathematically, we have:

[tex]\mathbf{K.E_{avg} = \dfrac{1}{2}mv_{rms}^2}[/tex]

Provided that the speed (RMS) is constant, the average kinetic energy of sample A will be greater than the average kinetic energy of sample B because sample A has a greater mass than sample B.

Hi there!

We know that:

The given statement is false, change in state is considered as a physical chance because the state can be regained by using physical methods ~

for example boiling causes water to evaporate (converted into gaseous state) , but it can gain the liquid form again by Condensation ~

Answer:

False

Explanation:

This is False because boiling is not included in the chemical category.

We have that for the Question, it can be said that the maximum velocity is

From the question we are told

A 2.00kg block is attached to a horizontal ideal spring with a spring constant k=100Nm.

The block-spring system is set on a horizontal surface with negligible friction.

Generally the equation for the Potential energy  is mathematically given as

[tex]P.E=\frac{1}{2}Rx_m^2\\\\2=\frax{1}{2}*100x_m^2\\\\x_m^2 = 0.04m\\\\x_m = 0.2m[/tex]

The PE is converted to KE, Therefore

[tex]KE = 2\\\\\frac{1}{2}MV_m^2 = 2\\\\V_m^2 = \frac{4}{M}\\\\V_m^2 = \frac{4}{2}\\\\V_m = \sqrt{2}\\\\V_m = 1.414m/s[/tex]

Complete Question

A 2.00 kg block is attached to a horizontal ideal spring with a spring constant k = 100 N The block-spring system is set on a horizontal surface with negligible friction. A graph of the potential energy U as a function of time t for this system is shown. The maximum displacement IMAX of the block from its equilibrium position and the maximum speed Umat of the block during the motion represented by the graph are most nearly A IMAX = 2.0 m and UMAX 1.4" B UMAX = 1.4 and UMAX=0.20" с MAX 0.20 m and UMAX = 1.4" D IMAX 0.40 m and UMAX 1.4 E IMAX 0.04 m and UMAX 2.0"

Answer:

a) Gradient = rise/run = mass/volume

since the graph is mass against volume we know mass is on the y-axis and volume is on the x-axis

in physics it’s best to use a larger part of the graph to find the gradient, so imma use the biggest values.

90/4.5 = 20

(additional note: sometimes you may get a different gradient. For example, when using 30 and 1.4 you get ≈21 this is an anomalous result since ita gradient differs; a mass against volume graph is supposed to be linear)

b) gradient represents density (p) since gradient is = mass/volume. And density also = mass/volume

For c and d just plot the points and you’ll be able to read from the graph to get the values.

I got this graph (the image)

but you’ll be able to interpret better when ‘you’ draw it (so try plotting it)

Ruler. A steel ruler aids the measurement and layout of straight lines. The ruler, also called "straightedge" or "straight-edged ruler," is a long, thin strip of wood, metal or plastic marked with increments of measurement.

Measuring Tape. The modern measuring tape's roughly palm-sized casing contains a coiled strip of metal marked with increments of measurement. The metal strip, called "tape," attaches to a spring which automatically retracts the tape into the casing following use.

Walking Tape Measure. The walking tape measure, also called "surveyor's measure," records the distance traveled by a wheel. An operator pushes the measure's wheel, similar to a bicycle wheel, by a handle as an attached ticker box displays feet or meters in the same format as a car's odometer.

The three things that occur naturally everyday and how science has had an impact on what we think or do about them is

Photosynthesis is a process in which green plants manufacture there own food in the presence of sunlight through the equation below

6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂

From the equation above, it can be seen that aside from the food (C₆H₁₂O₆) produced by green plants during photosynthesis, science has assisted us in knowing that these green plants take-up the carbon dioxide (CO₂) that is exhaled by humans and release the oxygen (O₂) that is inhaled by humans thereby purifying the air of the surrounding they are found. This concept has made man understand the importance of planting in residential areas.

Depletion of the Ozone layer; the ozone layer is a layer in the earth stratosphere which shields the earth from direct sunlight/rays. Over the years, the burning of hydrocarbon on earth has caused the depletion of this layer thereby exposing the earth to more direct sunlight from the sun. Science has had an impact in the thinking of man in this regard by making us more conscious of the risk of burning these hydrocarbons which has led to the collective efforts by governments across the world to minimize the burning of these substances.

Rain; rain are droplets of water that fall from the atmosphere. Rain formation occurs when water (in the form of ocean, river and/or seas) are evaporated into the atmosphere as a result of heat from the sun. These evaporated water molecule rises and cools down to form and form a cloud It is then returned to earth in the form of rain. This explanation changes the mythical understanding of rain in different culture
