Answer:

A 2-column table with 4 rows. The first column has entries glass, baby oil, maple syrup, wax. The second column has entries 2.40 grams per centimeter cubed, 0.83 grams per centimeter cubed, 1.37 grams per centimeter cubed, 0.93 grams per centimeter cubed.

Use the information in the table to predict whether each substance will sink or float in water. Note that the density of water is 1.0 g/cm3.

Glass:

✔ sinks

Baby oil:

✔ floats

Maple syrup:

✔ sinks

Wax:

✔ floats

notka56 [123]

Answer:

2.73 K

Explanation:

The Cosmic Microwave Background (CMB) radiation are a type of electromagnetic radiations that are released after the  explosion of the big bang. It propagates in all direction in space and is moving further with the expansion of the universe. They are not visible but they are helpful in estimating the age of the universe.

These radiations have a wavelength of about 970 μm (approximately 1 mm).

The temperature of the corresponding blackbody of this radiation is approximately <u>2.73 K(-270.42°C)</u> and its extremely cold.

A pitcher can throw a baseball at about 90 miles/hour (about 39.6 m/s). What is the ratio of the kinetic energy to the rest ener
tester [92]

Answer:

8.71*10^{-15}

Explanation:

The rest energy is the energy associated with the base ball at zero velocity which is expressed as

Rest energy=mc^{2}\\

Note: the speed C is the speed of light which is expressed as 3*10^8

while the kinetic energy is the energy associated with the ball during its motion and is expressed as

Kinetic energy=1/2mv^{2}

the ratio can be expressed as

\frac{Kinetic Energy}{Rest Energy}=\frac{\frac{1}{2}mv^{2} }{mc^{2}}\\since V=39.6m/s\\C=3*10^{8}m/s\\\frac{Kinetic Energy}{Rest Energy}=\frac{\frac{1}{2}39.6^{2} }{(3*10^8)^{2}} \\\frac{Kinetic Energy}{Rest Energy}=\frac{784.08}{9*10^{16}} \\\frac{Kinetic Energy}{Rest Energy}=8.71*10^{-15}

How does one get 8.0 A? The answer is D
ra1l [238]

I don't know why the answer is D , because I can't see the list of choices.


The only way to get 8.0 Amps is by making a serious mistake.

The current in the second picture is 4.0 Amps.


If the resistors are identical, then the effective resistance of

two resistors in parallel is 1/2 the resistance of each one.


The resistance in the second picture is 1/2 the resistance

in the first picture.


Current = (voltage) / (resistance)


Cutting the resistance in half causes the current to double.


If the current was 2.0 Amps in the first picture, it's 4.0 Amps

in the second picture.

Sphinxa [80]

Answer:

a

The speed is   s =  5.857 m/s

b

The distance is  D = 22.4  \  m

Explanation:

From the question we are told that

     The speed of the banana is  v =  16 \ m/s

   The distance from my  location is  d =  8.2  \ m  

     The time taken is  t = 1.4 \ s

The speed of the ice cream is

          s =  \frac{d}{t}

substituting values

        s =  \frac{8.4}{1.4}

        s =  5.857 m/s

The distance of separation between i and Valdimir is the same as the distance covered by the banana

   So  

          D =  v * t

substituting values

        D = 16 *  1.4

        D = 22.4  \  m
