Answer:
two objects must have accelerations of equal magnitude.
Explanation:
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
Where,
a is acceleration measured in 
v and u is final and initial velocity respectively, measured in 
t is time measured in seconds.
Acceleration constraint refers to a precise relationship between the acceleration of two physical objects.
An acceleration constraint says that in some circumstances two objects must have accelerations of equal magnitude.
The key difference between a bomb calorimeter and a coffee cup calorimeter is high temperature.
<h3>
What is bomb calorimeter?</h3>
A bomb calorimeter is an apparatus that can measure heats of combustion, used in various applications such as calculating the calorific value of foods and fuels.
<h3>What is coffee cup calorimeter?</h3>
A coffee cup calorimeter is a cup used to provide insulation when materials are mixed inside of it.
<h3>Difference between the two calorimeter</h3>
- The coffee cup calorimeter can't be used for high-temperature reactions, either, because they would melt the cup.
- A bomb calorimeter is used to measure heat flows for gases and high-temperature reactions

Answer:
B.
Explanation:
I'm not sure if it's the right answer but I think it is. I hope I helped out in some way.
A. speeding up 10 m/s every second.
an acceleration with a negative number simply implies direction.
positive being north (for example) and negative being south
Answer:
The correct answer is C) Always true
Explanation:
The law of conservation of energy states that energy cannot be created or destroyed. That implies that the total energy of a isolated system is constant. The energy can change from one form to another with not net loss or gain. For example, in a washing machine, the electrical energy supplied is transformed to mechanical energy which moves the tub. This law constitutes a fundamental principle of thermodynamics and physics, so<u> it is always true.</u>
