Answer:
so he can know where to put the heating things so he will know which place will trap the most heat. He will also need to know that depending on where he puts the cooling system, where it will make the most use.
Explanation:
The answer is energy , I hope that helped
Answer:
D
Explanation:
the total speed and the total mass of the entire system remain the same weather one object is moving or stationary.
When two or more objects collide, the collision does not change the
total momentum of the two objects.
Whatever momentum is lost by one object in the collision is gained
by the other. The total momentum of the system is conserved.
In order to keep the object moving in the same direction and with same speed, its initial and final momentum should be zero.
∴ Net force on the object should be zero.
The decay function is of the form
where
N₀ = initial amount
k = decay constant
t = hours
The material decays by 10% in 95 hours. Therefore
The time for the half life is given by
Answer: The half life is 625 hours
