Answer:
Explanation:
Given that,
Mass, m = 27 grams
Volume of the substance, V = 15 cm³
We need to find the density of the substance. We know that, the density of an object is given by mass per unit volume. So,
So, the density of the substance is equal to 
.
Answer:
Final temperature of the mixture becomes
Explanation:
Here we know that heat given by the nail is equal to the heat absorbed by water
So here we know that heat to change the temperature is given as
so by equating the heat we have
now we have
Answer:
Newton's first law is often called the law of inertia.

C. Newton’s Third Law of Motion.
Because...
Newtons third law implies conversation of momentum it can also be seen as following from the second law: when one object pushes a second object at some point of contact using an applied force, there must be an equation of opposite force from the second object that cancels the applied force. Otherwise, there would be a nonzero net force on a massless point which, by the second law, would accelerate the point of contact by an infinite amount.
