amm18123 years ago
5 0

When a light wave strikes an object, it can be absorbed, reflected, or refracted by the object. All objects have a degree of reflection and absorption. ... In the natural world, light can also be transmitted by an object. That is, light can pass through an object with no effect (an x-ray, for example).

Match each prefix to the correct multiple of 10. 1. centi- 10 2. kilo- 100 3. deka- 1000 4. milli- 1/100 5. hecto- 1/10 6. deci-
Mice21 [21]

Explanation :

There are some basic metric conversions.

Prefix                   Multiple of 10

centi                            \frac{1}{100}

Kilo                              1000

deka                              10

milli                              \frac{1}{1000}

hecto                            100

deci                              \frac{1}{10}

For example :

1cm=\frac{1}{100}m\\\\1Km=1000m\\\\1mm=\frac{1}{1000}m\\\\1Km=10\text{ hecto meter}\\\\1Km=100\text{ deka meter}

A square coil of wire of side 3.95 cm is placed in a uniform magnetic field of magnitude 2.25 T directed into the page as in the
Len [333]

Answer:

Explanation:

In this case we shall calculate rate of change of flux in the coli to calculate induced emf .

Flux through the coil  = no of turns x area x magnetic field perpendicular to it

=34 x  2.25 x (3.95 )²x 10⁻⁴ Weber

= 1193.4  x 10⁻⁴Weber

Final flux through the coil after turn by 90°

= 1193.4 x 10⁻⁴ cos 90 ° =0

Change of flux

= 1193.4 x 10⁻⁴ weber.

Time taken = 0.335 s .

Average emf= Rate of change of flux

= change in flux / time

=1193.4 x 10⁻⁴ / .335

= 3562.4 x 10⁻⁴

356.24 x 10⁻³

=356.24 mV.

Current induced = emf induced / resistance

= 356.24/.780

= 456.71 mA.

Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound. It is represented by
quester [9]

A study assessing the effect of anxiety Sound intensity, I, from a spherical source is a function of the distance, r, from the source of the sound.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have negative effects on our physical spherical. Anxiety speeds up our heartbeat and breathing, concentrating blood flow to the parts of our brains that need it. You are spherical ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, spherical with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.

What is the difference between an electrolyte and a nonelectrolyte
Pepsi [2]

Answer:

The difference between the Electrolyte and Non-Electrolyte are given in the explanation part.    

Explanation:

  • ELECTROLYTES are salts or molecules which ionize in solution fully.
  • Electrolyte solutions thus conduct electricity readily.    

 whereas

  • NON ELECTROLYTES in water do not dissociate from ions,
  • non-electrolyte solutions do not conduct electricity.
