The acceleration of gravity on Mars is about 3.7 m/s². (b)
So anything located on the surface of Mars weighs about 38% of what it would weigh if it were on Earth.
Answer: What is the force acting down the plane?
• Opp= hyp (sinq)= 450(sin30)= 225 N
• What is the force acting perpendicular to the plane?
• adj= hyp (cosq)= 450(cos30)= 390 N
Explanation:
If the heat change of the surroundings (such as the solution the reaction is occurring in) is determined to be 2.7 kJ, what is the heat change of the reaction (qrxn)?
Answer: First of all we can conclude that this is an exothermic reaction. The reason being that an exothermic reaction is one that produces a temperature increase in a isolated system giving off heat to the surroundings. Therefore the heat of the reaction is a negative quantity (qrxn < 0).
I hope it helps, Regards.
