meters away?
Answer:
60m/s
Explanation:
v=s÷t
75m÷1.25s=60m/s
Answer
60
Explanation:
This is because if the question gives you the distance and the time, you have to find the speed.
B In meteorites
C In the Big Bang
D In the Earth itself
E In the Sun
1. A teacher challenges.students to study moon phases to determine if what they have learned from the textbook is accurate. How might a student investigate claims made in a textbook that moo. phases occur in a 28-day cycle?
A. observe the phase of the moon each night until a full moon can be seen.
B. Compare the textbook phases to the actual moon phases seen in the night sky each night in 28 days periods over a three month time frame.
C. Compare diagrams of moon phases from the textbook to diagrams of moon phases on-line
D. Observe the moon phases seen in the night sky as often as possible over a six month period.

Explanation:
Energy from an outside source is continuously being added
B.
The reaction container always feels cold.
C.
The reactants have more heat energy than the products.
D.
More heat is given off than is put into the reaction.
The statement which is true about exothermic reactions is as follows:
Thus, the correct option for this question is C.
An exothermic reaction may be defined as a type of reaction in which energy is significantly liberated in the form of heat or light. In such types of reactions, energy is generally transferred into the surroundings rather than utilized from the surroundings.
The option "energy from an outside source is continuously being added" represents an endothermic reaction in which heat or light energy is externally been provided. The option "more heat is given off than is put into the reaction" is not absolutely true because exothermic reactions liberate energy but it does not matter if it is higher or lower than that of being put into the reaction.
Therefore, the reactants have more heat energy than the products is a statement that is true about exothermic reactions. Thus, the correct option for this question is C.
