Answer:
The temperature change of the copper is greater than the temperature change of the water.
Explanation:
deltaQ = mc(deltaT)
Where,
delta T = change in the temperature
m =mass
c = heat capacity
The temperature change in the copper is nearly 11 times the temperature change in the water.
So, the correct option is,
The temperature change of the copper is greater than the temperature change of the water.
Hope this helps!
Answer:
The value is
Explanation:
From the question we are told that
The initial speed of the roller coaster is
The length of the hill is
The acceleration of the roller coaster is
Generally the acceleration is mathematically represented as
Here is the initial time which is equal to zero
is the final velocity which is mathematically represented as
So
Solving this using quadratic formula we obtain
Generally time cannot be negative so
Generally the final velocity is mathematically represented as
