The time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.
<h3>How to calculate deceleration?</h3>
Deceleration is the amount by which a speed or velocity decreases (and so a scalar quantity or a vector quantity).
The deceleration of a body can be calculated using the following formula:
-a = (v - u)/t
Where;
- -a = deceleration
- v = final velocity
- u = initial velocity
- t = time in seconds
-2 = (28 - 36)/t
-2t = -8
t = 4s
Therefore, the time it will take if a car change the velocity from 36m/s to 28m/s with an acceleration of -2.0m/s² is 4s.

Answer:
R= 20 ohm
Explanation:
Given that
Current ,I = 6 A
Voltage difference ,ΔV = 120 V
Lets take resistance of the stem iron = R
We know that ,the relationship between current ,voltage difference and resistance is given as
ΔV = I R
Now by putting the values in the above equation we get
R= 20 ohm
Therefore the resistance of the steam will be 20 ohm.
C because the air will push him closer to the space station

All metals except potassium and sodium, have a property known as malleability. Malleability is the quality of something that can be shaped into something else without breaking. So when aluminium and copper are hammered they will not break. Rather they will change shape and become thin or flat at the area where its hammered.
All Non- metals except diamond are brittle in nature, so when we hammer it , they will break down into pieces. So when ice and glass will be hammered they will shatter into pieces.
