the more chicken soup you add to the water the lower the pH scale goes to being acidic. chicken soup has the pH of 5.8 and water is neutral meaning it has a pH scale of 7.

A cosmic ray electron moves at 7.45 â 106 m/s perpendicular to the earth's magnetic field at an altitude where field strength is
kupik [55]
The magnetic force on the electron is:
F=qvB \sin \theta
where q is the electron charge, v the electron speed, B the magnetic field intensity and \theta is the angle between v and B. Since the electron is traveling perpendicular to the magnetic field, \sin \theta = \sin 90^{\circ}=1, so we can write 
F=qvB

This force acts as centripetal force of the motion, F_c = m \frac{v^2}{r}, where m is the electron mass and r the radius of the circular orbit. So we can write:
qvB=m \frac{v^2}{r}
and by re-arranging this equation, we find the radius of the circular orbit, r:
r= \frac{mv}{qB}= \frac{(9.1 \cdot 10^{-31}kg)(7.45 \cdot 10^6 m/s)}{(1.6 \cdot 10^{-19}C)(1.10 \cdot 10^{-5}T)}=  3.85 m

How does a sound wave transfer energy to your ears ?
horrorfan [7]

Answer:

A. Particles in air move in circles as the wave moves forward.

B. Particles in air move forward but not backward as the wave moves

forward.

C. Particles in air move up and down as the wave moves forward.

✔ D. Particles in air move forward and backward as the wave moves

forward.

Explanation:

The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.

Which situation is the best example of translational motion? Question 1 options: a coin spinning on a desk a leaf blowing across
lukranit [14]

Translational motion is a type of motion in which objects move with a change in position. The situation that best shows the translational motion is leaf blowing in the field.

Translational Motion:

It is a type of motion in which objects move with a change in position.

For example- leaf blowing in the field.

  • Coin spinning on the desk does not change its position.
  • A car in the parking lot with running engine does not change its position.
  • Standing in feet is not any kind of movement.

Therefore, the situation that best shows the translational motion is leaf blowing in the field.

A 10-ohm resistor has a constant current. If 1200 C of charge flow through it in 4 minutes what
Amanda [17]

Answer:

B 5.0 A .

Explanation:

Hello.

In this case, since we know the charge (1200 C), time (4 min =240 s) and resistance (10Ω) which is actually not needed here, we compute the current as follows:

I=\frac{Q}{t}

Then, for the given data, we obtain:

I=\frac{1200C}{4min}*\frac{1min}{60s}\\\\I=5A

Therefore, answer is B 5.0 A .

Best regards!
