Answer:

1. El objetivo principal del test es medir la fuerza abdominal y las cantidad de grasa abdominal acumulada. Además, nos ayuda a saber cuanto rinde el cuerpo con esta actividad física.

2. Es importante saber la capacidad física abdominal para prevenir dolores, desgarros, enfermedades, además, este ejercicio es perfecto para aumentar la energía y la masa muscular abdominal.

3. Al saber como mejorar nuestro rendimiento, nuestra fuerza y masa muscular abdominal tu cuerpo ya no sentirá lo mismo con el tiempo por lo tanto, añadiendo rutinas nuevas mejoraras tu capacidad física.

Explanation:

The purpose of the abdominal test is to measure the physical condition and measure the strength of the person's abdominal muscles, it also determines the abdominal resistance taking as a measure the number of abdominals you can do in 30 or 60 seconds.

A sample of gas with an initial volume of 28.4 Liters at a pressure of 725 mmHg and a temperature of 305 K is compressed to a vo
Lerok [7]

Answer:

The final pressure is 2.25 atm or 1710 mm Hg

Explanation:

Step 1: Data given

The initial volume = 28.4 L

The initial pressure = 725 mm Hg ( = 725/760 atm) = 0.953947 atm

The initial temperature = 305 K

The new volume is 14.8 L

The new temperature = 375 K

Step 2: Calculate the new pressure

(P1*V1)/T1 = (P2*V2)/T2

⇒ with P1 = the initial pressure = 725 mmHg = 0.953947 atm

⇒ with V1 = the initial volume = 28.4 L

⇒ with T1  = The initial temperature = 305 K

⇒ with P2 = the new pressure = TO BE DETERMINED

⇒ with V2 = the new volume = 14.8 L

⇒ with T2 = the new temperature = 375 K

(0.953947 * 28.4)/305 = (P2 * 14.8)/375

P2 = 2.25 atm = 1710 mm Hg

The final pressure is 2.25 atm or 1710 mm Hg

Describe the charges of the particles in the atom and how charge is distributed within an atom.
trapecia [35]
There are MANY subatomic particles in an atom.
But the three most important ones are
The electron which has a negative charge.
The proton having a positive charge.
And the neutron which is neutral or which has no charge at all.
The protons and neutrons club together and form the inner, heavy part of the atom which is positively charges because of the protons known as the nucleus.
And electrons remain farther away in all reality and revolve around the inner positive nucleus.
Trying its best to make the whole atom neutral!

Which equation represents the combined gas law?
stealth61 [152]

Answer:

P1V1/T1= P2V2/T2

Explanation:

Combined gas law involves Boyle's law and Charles law altogether with the formula of Boyle's law as P1V1=P2V2

formula for charles law as V1/T1=V2/T2

so when combined form P1V1/T1=P2V2/T2
