Because water is a polar molecule, it has a slightly positive side and a slightly negative side

Answer:  TRUE , water is a polar molecule, it has a slightly positive side and a slightly negative side.

Explanation: Water is polar molecule , term polar means it has positive and negative sides. Polarity of water is because of its bent shape. H2O has 10 protons and 10 electrons. In water unequal sharing of electrons takes place because oxygen attracts electrons more strongly in compare to the two hydrogen atoms. Because of this unequal sharing of electrons water has slightly positive charge at hydrogen atoms and slightly negative charge at oxygen atom.

It is TRUE that water is a polar molecule because it has a slightly positive side and a slightly negative side.

 

To add, when a covalently bonded molecule has more electrons in one area than another, it is called a polar molecule, and water has a covalently bonded molecule.

A series RCL circuit consists of a 50 Ω resistor, 500 Ω capacitor, and a 500 Ω inductor. What is the angle of impedance?
lbvjy [14]

Answer:

Zero

Explanation:

here, the inductive reactance and the capacitive reactance is same, so this is the condition for resonance.

In the condition for resonance,

the circuit and the voltage in the circuit is in the same phase and the impedance of the circuit is minimum which is equal to the resistance of the circuit.

The phase angle is given by

tan\phi =\frac{X_{L}-X_{C}}{R}

Ф = 0

When developing an experiment design, which could a scientist take to improve the quality of the results?
Bad White [126]

The options missing are;

A. Make only a few changes to the manipulated variable.

B. Identify any biases about the answer to the scientific question.

C. Include as many details as possible when writing the conclusion.

D. Share her ideas through peer review.

Answer:

B. Identify any biases about the answer to the scientific question.

Explanation:

Since the question is asking what can be done to improve the quality of the results, it means what can the scientist do to make sure that the result answers the question properly and has little or no biases.

Thus, looking at the options, the only one that comes close to actually improving on the quality of the results before finalizing is option B where the scientist is to identify any biases.

kakasveta [241]

Answer:

Microwave: Radiation

Water: Conduction, convection & radiation.

Explanation:

  • When we heat a food using microwave then the water content of the food is only heated by the microwave.
  • Microwaves make the molecules of water vibrate frequently with a frequency closer to the frequency of microwaves and this increases the kinetic energy of the molecules which produces heat in the water molecules this heat then propagates to the whole food by conduction and convection, but the heat enters the food only via radiation.

Now when the food item is kept into warm water then the molecules closer to the food heat the food by conduction through direct energy transfer by lattice vibrations and when they become cooler than the mass of water all around then due to density difference they settle down and their place is occupied by warmer molecules around in the fluid leading to convection.

Radiation of energy from a mass occurs continuously irrespective of the medium present there. So the heat of water also enters the food by radiation of energy from the water molecules.
