Complete Question
Alberta is going to have dinner at her grandmother's house, but she is running a bit behind schedule. As she gets onto the highway, she knows that she must exit the highway within 55 min if she is not going to arrive late. Her exit is 43 mi away. How much time would it take at the posted 60 mph speed?
Answer:
The time it would take at the given speed is
Explanation:
From the question we are told that
The time taken to exist the highway is
The distance to the exist is
Alberta speed is
The time it would take travelling at the given speed is mathematically represented as
substituting values
Converting to minutes
1 hour = 60 minutes
So 0.71667 hours = x minutes
Therefore
i would say 4 seconds because according to the graph the flat line is where the dog stopped.
Answer:
Glucose and Oxygen
Explanation:
Cellular respiration is the process whereby cells derives energy by the use of glucose and oxygen.
Organisms that use cellular respiration to produce their energy are known as heterotophs. They derive the glucose from food materials obtained from plant sources. They use the oxygen from the environment to liberate energy from the glucose obtained from feeding on plant materials.
Cellular respiration can be simply expressed as shown below:
GLUCOSE + OXYGEN → CO₂ + H₂O + ATP
The reactants are glucose and oxygen.
The products are CO₂, water and ATP
Answer: 110 cal
It is given that he specific heat of Iron is .
Mass of iron fork 20 g
Heat energy is needed to raise the temperature of this from
we can use the following formula to calculate heat energy:
where Q is the heat required to raise the temperature by of a mass m having specific heat C.
Insert the values:
Thus, heat required to raise the temperature of iron fork is 110 cal.
