At rest, initial speed zero

x=v(initial) t+ 1/2 at^2
-1000m=0(10) + 1/2 a 10^2
-1000m=50a
a = -20 m/s^2

What type of reproduction does slime mold have?<br> (I need the answer right now)<br> thanks:)

notka56 [123]

The slime mold will create a stalk with new spores in it, called a "fruiting body". These spores will make new patches of slime mold. This is a form of asexual reproduction.

a slender rod of mass m and length l is released from rest in a horizontal position. what is the rod's angular velocity when it

Makovka662 [10]

Answer:

M g H / 2 = M g L / 2 initial potential energy of rod

I ω^2 / 2 = 1/3 M L^2 * ω^2 / 2 kinetic energy attained by rod

M g L / 2 = 1/3 M L^2 * ω^2 / 2

g = 3 L ω^2

ω = (g / (3 L))^1/2

Where else could Snell’s law be useful in determining the path of a light ray in your everyday life?

Musya8 [376]

Answer:

Contact glasses.

Explanation:

-Anytime you put on a pair of glasses, or see light bend through a glass of water or a prism, this rule is in action.

-In short, Snell's law governs the angle by which electromagnetic radiation such as light refracts, or changes direction, as it passes from one material to another and slows down.

How to keep my family safe during a hurricane?

alexdok [17]

If you are not advised to evacuate or are unable to do so safely, stay indoors, away from windows, skylights and doors. Continue to monitor weather reports and do not go outside until the storm has passed. And, to protect your children from seeing too many sights and images of the hurricane, limit media exposure.

A lightning flash releases about 1010J of electrical energy. Part A If all this energy is added to 50 kg of water (the amount of

zavuch27 [327]

Answer:

water is in the vapor state,

Explanation:

We must use calorimetry equations to find the final water temperatures. We assume that all energy is transformed into heat

E = Q₁ + $Q_{L}$

Where Q1 is the heat required to bring water from the current temperature to the boiling point

Q₁ = m $c_{e}$ ( $T_{f}$ -T₀)

Q₁ = 50 4180 (100 - 37)

Q₁ = 1.317 10⁷ J

Let's calculate the energy so that all the water changes state

$Q_{L}$ = m L

$Q_{L}$ = 50 2,256 106

$Q_{L}$ = 1,128 10⁸ J

Let's look for the energy needed to convert all the water into steam is

Qt = Q₁ + $Q_{L}$

Qt = 1.317 107 + 11.28 107

Qt = 12,597 10⁷ J

Let's calculate how much energy is left to heat the water vapor

ΔE = E - Qt

ΔE = 10¹⁰ - 12,597 10⁷

ΔE = 1000 107 - 12,597 107

ΔE = 987.4 10⁷ J

With this energy we heat the steam, clear the final temperature

Q = ΔE = m $c_{e}$ ( $T_{f}$ -To)

( $T_{f}$ -T₀) = ΔE / m $c_{e}$

$T_{f}$ = T₀ + ΔE / m $c_{e}$

$T_{f}$ = 100 + 987.4 10⁷ / (50 1970)

$T_{f}$ = 100 + 1,002 10⁵

$T_{f}$ = 1,003 10⁵ ° C

This result indicates that the water is in the vapor state, in realizing at this temperature the water will be dissociated into its hydrogen and oxygen components
