Based on Newton's principle, whenever objects A and B interact with each other, they exert forces upon each other.
When a horse pulls on a cart, t<span>he horse exerts a force only to the cart. But that force applies only to the cart, not to the horse.
The cart in turn exerts a force on the horse. But that force applies only to the horse, not the cart also.
</span>
There are two forces resulting from this interaction - a force on the horse and a force on the cart. T<span>he net force on the cart remains as it was --- a positive force in the direction of the horse's movement. Therefore, the cart begins to accelerate and move.</span><span>

That my friend is known as a chode.
The answer you are looking for would be C. "She asks her lab partner which base he thinks is hardest to study"
This is the correct option out of the other choices.
A. She uses a acid-base indicator to measure the pH of four different solutions
B. She mixes two solutions and measures their pH before and after
C. She asks her lab partner which base he thinks is the hardest to study
D. She measures the temperature of a solution before and after adding H2SO4
Heat = mass (m)*specific heat (C)* change in temperature (Δt)
In the current scenario,
mass = 200 g = 0.2 kg
C = 0.11 kCal/kg.°C
Δt = 10 °C
Therefore,
Heat = 0.2*0.11*10 = 0.22 kCal = 0.22*4186 J = 920.92 J
