Answer:

c. higher than other liquids

Explanation:

As many other anomaly in water, heat capacity is consequence of relatively strong hydrogen bonds. Because of these bond, molecules of water need more energy (than many others liquids) to increase their movement (vibration) and, finaly, to increase temperature of water.

Calculate the wavelength of a football (425g) thrown by an NFL quarterback traveling at 50mph

AnnyKZ [126]

Wavelength is 6.976 x 10^ -35 m

Explanation:

In this, we can use De Broglie’s equation. This equation is the relationship between De Broglie’s wavelength, velocity and the mass of a moving object. In this equation, we are using plank's constant which is 6.626 x 10^-34 m^2 kg/s.

We know that one mile per hour is equivalent to 0.447 M/S.

And One gram is equivalent to 10^-3 kg.

De Broglie’s wavelength = λ ( wave length) = Plank’s constant/ Mass x velocity

λ ( wave length) = 6.626 x 10^ -34/ (425 x10^-3) x ( 50 x 0.447)

= 6.626 x 10^ -34/ 0. 425 x 22.35

= 6.626 x 10^ -34/ 9.498

= 6.976 x10^ -35 m

So, the wavelength of the football will be 6.976 x 10^ -35 m

please help!!!!!! What is the mass of 1 mole of magnesium (Mg)? Express your answer to four significant figures. The mass of 1 m

Semmy [17]

I believe you just look at your periodic table for this value. I don't think there is any math involved.
Therefore one mole of Mg = 24.305g.

Whats a particle of electormagnetic radiation

Tpy6a [65]

Answer:

Scientists have observed that electromagnetic radiation has a dual "personality." Besides acting like waves, it acts like a stream of particles (called "photons") that have no mass. The photons with the highest energy correspond to the shortest wavelengths.
