Answer:
5m/s²
Explanation:
Given parameters:
Initial velocity = 10m/s due east
Final velocity = 30m/s due east
Time = 4s
Unknown:
Acceleration of the car = ?
Solution:
Acceleration is the rate of change of velocity with time.
Mathematically;
Acceleration = 
v is the final velocity
u is the initial velocity
t is the time taken
Insert the parameters and solve;
Acceleration = 
= 5m/s²
Answer:
an endothermic reaction
Explanation:
An endothermic reaction has occurred.
You can have a solution of hydrogen peroxide that might say 10% that means that 10% per mass of the hydrogen peroxide solution is the hydrogen peroxide the rest is water.
concentration is the amount of mass in the solution eg 5gdm-3
