It would be 0-20/4 so it’d be -5 meters per second
Answer:
Independent variable: Force applied to the car
Dependent variable: The acceleration of the car
Explanation:
A scientific experiment involves three variables which are classified mainly as independent, dependent and constant variables.
The independent variable is the variable which can be changed or changes itself like weather, natural conditions and in a given question, the applied force on the car is considered.
The dependent variable is the variable which depends on the independent variable that is the force applied on the car. Therefore, the acceleration of the car can be considered as a dependent variable as it changes according to the applied force.

Lithium Chloride releases 37 kJ of energy per mole when dissolved in water.
Energy released = 0.25 x 37
= 9.25 kJ
= 9,250 J
Temperature change of water may be calculated using
ΔH = mCpΔT
Cp = 4.18 J/g
ΔT = 9,250 / (200 x 4.18)
ΔT = 11.1 °C
Is their a picture or something?
