Answer: 30 N (in the direction of the 45 N force)
Explanation:
You have to choose a positive and negative direction since the question says the forces are in opposite directions.
Lets assume:
- <----------> +
<------ 15 N
45 ------->
45-15=30
Answer:
is a double displacement reaction
- is a redox reaction
- is a combination reaction
- is a decomposition reaction
Explanation:
It is of the form
Both oxidation and reduction occur in this reaction. Fe gets oxidized and H gets reduced.
It is an exothermic combination reaction. Calcium reacts with water to produce calcium hydroxide and heat is released in this process.
It is a decomposition reaction where nickel chloride decomposes to nickel and chlorine.
The mass because u can look at this formula
F = G(m1 - m2/ d squared) - Do u see volume in this equation?
Answer:
40 km/h
Explanation:
First...
Look at the formula speed is equal to the distance over time or s = d/t.
Next...
Use the formula: 240/6.0
Finally...
Solve: 40
So the answer: 40 km/h
Explanation:
The atmosphere is heated in several ways - heat from the core of the Earth, by radiation from the Sun, conduction from contact with warm land and water, convection to even out the temperature and by absorption of infrared radiation from the warm land and water. The core of the Earth is very hot.
