Friction can be reduced by making the surface smoother, lubricating the surface, or reducing the contact between the forces.
Hope this helps!
Answer:
The order of steps for writing a chemical formula is 3, 2, 1, 5, 4
Explanation:
Balance the charges. Identify the negative ion and charge. Identify the positive ion and charge. Use the information in the ratio to write the chemical formula. Write the ratio of ions that balances the charges.

I think its the sun not 100% sure...
Answer:
Explanation:
Newton's 2nd law is given as 
.
To find the acceleration in the horizontal direction, you need the horizontal component of the force being applied.
Using trigonometry to find the horizontal component of the force:
Use this horizontal component of the force to solve for for the acceleration of the object:
C. A hypothesis :) hope this helped
