A basketball weighs 20. ounces and has a volume of 456 in3. what is the average density of the basketball in g/cm3?

The chemical formula of diiodine pentoxide is I2O5.

The chemical compound with the formula I2O5 is known as iodine pentoxide. The only stable iodine oxide is this one, which is the anhydride of iodic acid. It is made by dehydrating iodic acid in a stream of dry air at 200 °C.

2HIO3 = I2O5 + H2O.

At ambient temperature, iodine oxide (I2O5), which is created by dehydrating iodic acid (HIO3), is a white, crystalline solid that is stable up to 300°C (573K). I2O5 is a potent oxidizer. Its structure is described below. Iodine pentoxide is an oxidizing agent that transfers oxygen atoms to substrate. It functions as an oxidizing agent and speeds up the oxidation process by transferring oxygen atoms.

If John is 20.0 meters away from me and he is running away from me at 5.0 m/s. I sprint at 7.0 m/s to catch up. Then, I will take 10 seconds to reach him.

We know that,

Speed = Distance / Time

Time = Distance / Speed

Given that,

My speed = 7 m/s

John's speed = 5 m/s

Distance I need to cover to catch up John = ( 20 + x ) m

Distance John will cover before I catch up to him = ( x ) m

Since the time taken by both of us to reach that point is same,

( 20 + x ) / 7 = x / 5

100 + 5x = 7x

2x = 100

x = 50 m

Time required = Distance / Speed = 50 / 5

A fan blows the air and gives it kinetic energy, an hour after the fan has been turned off, the kinetic energy turns into thermal energy.

The fact that all energy is conserved causes a heat flow, which raises internal (or thermal) energy, as the air molecules slow and lose kinetic energy.

Kinetic energy, which may be seen in the movement of an object, particle, or group of particles, is the energy of motion. Any moving item uses kinetic energy, such as a person walking, a baseball being thrown, a piece of food falling from a table, or a charged particle in an electric field.

The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.

For a 166-lb person, a dose of 452 milligrams is prescribed to treat asthma.

Lung damage is a side effect of asthma. Repeated episodes of coughing, dyspnea, chest tightness, and wheezing are also brought on by it. By taking medication and avoiding the triggers that can set off an attack, asthma can be managed. Outdoor allergens, such as pollen from grass, trees, and weeds, are common asthma triggers. Different allergens and irritants might function as triggers for different people. Dust mites, cockroaches, mold, and pet dander are examples of indoor allergies. Air irritants like smoke, chemical fumes, and powerful scents.

A branch of physics called kinematics, which was evolved from classical mechanics, defines how points, bodies, and systems of bodies (groups of objects) move without taking into account the forces that propel them. The discipline of kinematics is sometimes thought of as a subfield of mathematics and is frequently referred to as the "geometry of motion." Any known values of the location, velocity, and/or acceleration of points inside the system are declared as initial conditions for a kinematics issue, together with the geometry of the system. The position, velocity, and acceleration of any unidentified system components can then be calculated using geometrical considerations.
