The deceleration of the car is observed as 2 m/s^2.
<h3>What is deceleration?</h3>
The term deceleration has to do with the decrease of velocity with time.
Given that;
v = 65 km/h or 18 m/s
u = 126 km/h to or 35 m/s
t = 8.5 s
a = ?
v = u - at
18 - 35 = -8.5a
a = 18 - 35/-8.5
a = 2 m/s^2

A = delta v over delta t delta v is calculated with final velocity less initial velocity so delta v is 14 - 6 that is 8m/s and delta t is calculated with final time less initial time as initial always is 0 then is 1 - 0 that is 1 then a = 8m/s over 1 that is 8 then the acceleration is 8m/s^2 (remember that is squared.)
Answer: primary ecological succession
Explanation:
Primary ecological succession: This occurs when a certain or some organisms dominate an area that was uninhabited of life. This may happen after a natural disaster that leaves the land barren. The presence of these organisms on the barren land will help the soil occupied to gain nutrients which will eventually allow some other plants to grow on it. The growth of plants will later invite insects and insects may invite animals.
Answer:
0 Kelvin
Explanation:
Atoms in absolute temperature get approximatelly motionless since 0 Kelvin is -273 degrees Celcius. The kinetic energy of atoms/particles in matter has the possible lowest value ( almost zero), so that there is nothing colder than 0 Kelvin.
Answer:
Hope this helps you find the answer
Explanation:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
