Answer:
Newton's First Law of Motion
Explanation:
Without external forces acting on an object, the object tends to move at constant speed in a straight line. This property is referred to as inertia. Newton's first law states this natural observation.
Answer:
<h3>The answer is 8.5 kg</h3>
Explanation:
The mass of the object can be found by using the formula
where
f is the force
a is the acceleration
So we have
We have the final answer as
<h3>8.5 kg</h3>
Hope this helps you
I believe it’s B; Theories may be proven to be true and become laws.
A would make sense if we were talking about hypotheses however, we’re not.
Hello There!
Well, technically no. It has to be one or the other, it can't be both.
Hope This Helps You!
Good Luck :)

When you bring two objects of different temperature together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object. Heat is energy on the move.
Units of heat are units of energy. The SI unit of energy is Joule. Other often encountered units of energy are 1 Cal = 1 kcal = 4186 J, 1 cal = 4.186 J, 1 Btu = 1054 J.
Without an external agent doing work, heat will always flow from a hotter to a cooler object. Two objects of different temperature always interact. There are three different ways for heat to flow from one object to another. They are conduction, convection, and radiation.
