Under ideal conditions some common bacteria can divide and double their numbers in less than one half hour. suppose one spring d

ay at 6am a few such bacteria fall into a can of strawberry surup in a broken garbage bag behind a snack bar. these conditions-warmth, moisture, and lots of food- are perfect growth, and the population doubles every 20 minutes. by 6pm the bacteria overcrowds and dry the food and is gone. at what time did the can of syurup become half full?

If the population doubles every 20 minutes, and the can is full at 6:00PM, then the can must have been half full 20 minutes before 6:00PM or 5:40PM 

<span>Likewise the can is: </span>
<span>Full at 6:00PM </span>
<span>Half full at 6:00-0:20 = 5:40PM </span>
<span>1/4 full at 5:40 - 0:20 = 5:20PM </span>
<span>1/8 full at 5:20 - 0:20 = 5:00PM </span>
<span>1/16 full at 5:00 - 0:20 = 4:40PM</span>

Answer: Nigeria and Liberia

Explanation:

A compact state is one where the distance from the center of the country is more or less the same to all the boundaries of the country.

Nigeria is a compact state with the center being in the capital of Abuja. Its compact nature allows for roads to be built easier. Liberia to the west of Africa is also a compact state with its shape being decided by European powers when they were scrambling for Africa in the Berlin Conference.

A 1.0 kg lump of clay is sliding to the right on a frictionless surface with speed 2 m/s . It collides head-on and sticks to a 0
Aleks [24]

Answer:

0J

Explanation:

Mass of the lump M1 = 1.0 kg, initial velocity of the lump U1 = 2m/s to the right,

mass of the metal sphere M2 = 0.5kg, initial velocity of the metal sphere M2 = -4m/s to the left. using conservation law of momentum;

M1U1 + M2U2 = V (M1 + M2)

(1.0 × 2) + (0.5 × -4) = V (1 + 0.5)

2 -2 = V (1.5)

0 = V (1.5)

divide both side by 1.5

0/1.5 = V 1.5/1.5

V = 0

since final velocity after sticking together of the two masses equals zero then their combined kinetic energy will also equal to zero

1/2 V(M1 +M2)

1/2 ×0 × 1.5 = 0J
