F = net force exerted on object
m = mass of the object
a = acceleration of the object.
According to Newtons 2nd law of motion, F = ma
SI unit of mass = kg
SI unit of acceleration = m/s^2 ( meter / second^2)
And SI unit of force = N ( Newton)
hello. could someone explain this formula please or atleast explain the names of the letters being...
Hello! Could someone please help me answer these two problems? Please explain all parts of your answer in as much detail as possible. Thank you! Dacron is a polyester formed by transesterification of dimethyl terephthalate with ethylene elycol to give a long-chain polymer. Provide a partial structure of the polymer that shows at least two of the repeating units. Meo,C но dimethyl terephthalate ethylene glycol Benzyloxychloroformate (Bno.c-C, PhCH-o-c-Cil) is an important reagent used in the synthesis of peptides as a...
this is the whole question which has 17 parts. I only need question (9-17) 6. A 50.0 kg man standing on a spring scale takes a descending elevator ride (DOWNWARD). Starting from the rest, the elevator descends, attaining a maximum speed of 6.0 m/s in 2.0 seconds. Then the elevator travels with this constant speed of 6.0 m/s for 10.0 seconds. Lastly, it takes the elevator 3.0 second to make a complete stop. Based on the information above, answer the...
Please neatly show me how to solve these with all the correct steps and explain so I can understand the process. Thanks Part (a) Suppose the force exerted by a spring is F(x) = -kx and the spring has constant k = 325 N/m. Then suppose a wooden cube with mass m = 6 kg traveling with an initial velocity on a level surface with kinetic coefficient of friction 0.250 presses against the spring and it compresses from x =...
I would really appreciate it if someone can help me with the whole question. thank you. You may be familiar with Newton's Second Law of Motion, SF = mā. In English, this equation says: The sum, or net, (S) of the forces (F) acting upon an object equals (=) the mass (m) of the object multiplied by the object's acceleration (ā). Even if you are familiar with this famous equation, did you notice the arrows above F and a before?...
could someone help me understand these problems, the proper steps to solve them please. 1) A person walks first at a constant speed of 1.35 m/s along a straight line from point to point and then back along the line from B to at a constant speed of 0.75 m/s. It takes the person 100s to walk from point @to point . a) What is her average speed over the entire trip? (10 points) b) What is her average velocity...
Can someone please help EXPLAIN this to me? I don't just want answers, I need EXPLANATIONS! I will mark it thumbs down if it is not explained to me and just given the answer. Thanks! Even if you could answer a few of them. Please, you'd be saving my grade. Just explain it. Equivalnets of hydroxide 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 pH a) What is the one letter code for...
