The emotions and associations connected to a word depending on our experiences is known as it's connotative meaning. It's determined to be positive or negative.
Examples:
Positive- childlike, dove(peace), hollywood(fame), home, lean, modest, slender, youthful
Negative- chatty, miserly, mutt, pushy, skinny, uppity, babe(woman), chick (woman)

Answer:

the pressure due to the water on the diver is 200,000 pascal

pressure = height × density × acceleration due to gravity

p = 20×1000×10

p=200,000 pascal

It is known that the kinetics of recrystallization for some alloy obeys the Avrami equation, andthat the value of n in the expon

trapecia [35]

Answer: $8.76\times 10^{-3} min^{-1}$

Explanation:

Given

n=5

0.3 fraction recrystallize after 100 min

According to Avrami equation

$y=1-e^{-kt^n}$

where y=fraction Transformed

k=constant

t=time

$0.3=1-e^{-k(100)^5}$

$e^{-k(100)^5} =0.7$

Taking log both sides

$-k\cdot (10^{10}=\ln 0.7$

$k=3.566\times 10^{-11}$

At this Point we want to compute $t_{0.5}\ i.e.\ y=0.5$

$0.5=1-e^{-kt^n}$

$0.5=e^{-kt^n}$

$0.5=e^{-3.566\times 10^{-11}\cdot (t)^5}$

taking log both sides

$\ln 0.5=-3.566\times 10^{-11}\cdot (t)^5$

$t^5=1.943\times 10^{10}$

$t=114.2 min$

Rate of Re crystallization at this temperature

$t^{-1}=8.76\times 10^{-3} min^{-1}$

Oil tends to float on water because the density of oil is _____ the density of water.

Rama09 [41]

Oil is less dense than water so it tends to float on the top of the water. Hope this Helps!

a person does 100 joules of work in pulling back the string of a bow. what will be the initial speed of a 0.5 kg arrow when it i

eduard

If all the energy she put into bending the bow is completely
transmitted to the arrow, then the arrow has the 100 joules
of kinetic energy when it leaves the bow.

   Kinetic energy = (1/2) (mass) (speed)²

   100 J = (1/2) (0.5 kg) (speed²)

Divide each side by 0.25 kg: 100 J / 0.25 kg = speed²

[ joule ] = [ newton-meter ] = kg-m²/sec²

100 kg-m²/sec² / 0.25 kg = speed²

   400 m²/sec² = speed²

Take the square root of each side: speed = √400 m/s

    20 m/s

      (about 44.7 mph)

A little help please?

Tpy6a [65]

A. Made of the marble.

the mass remains constant when you drop the marble but the rest of the variables change as the marble is dropped, therefore, the only constant variable is its mass.
