Answer:

free fall is any motion of a body where gravity is the only force acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it

Explanation:

Why do scientists need a standard system of measurement?
djyliett [7]
The answer is so that everyone is measuring the same distance and counting that distance as the same everywhere. one example from real life why it is important to use standard units is the loss of the NASA mars orbiter. some people decided that the units were to be in metric and others thought that the units were in imperial (english) system. so the orbiter was lost.

let's eliminate some choices
A. to allow for consistientcy with measurement data:
not really, just make sure the instruments are accurate.

B. to use tools marked in customary units: this could be true because a custom is something that is accepted in a wide area and if it is standard, then it is customary so b is the answer

C. so they can keep measurement data secret: nope

D. to record with easier abbreviations: not really

the answer is B

The equation shows neutralization of an acid and a base to produce a salt and water.
Masja [62]

The answer is; 2.

To balance a chemical equation, the moles on one side of the equation has to be the same as that on the other side. This ensures that the law of conservation  is observed because matter or energy can't be created or destroyed but can only be transformed from one form to another.

In this equation, putting 2 in front of NaCl ensures that there are 2 moles of Na and CL just as there are 2 moles of Na and CL in the reactants side.

Estimate the volume of each ball. Use the formula
Elanso [62]

Answer:

Vtennis = 134 [cm^3]; Vgolf = 40.76 [cm^3]

Explanation:

To solve this problem we must have the values of the radius or diameters of each of these balls, therefore performing an internet search we can appreciate that the diameters of these balls are:

Dt = 6.35[cm]

Dg = 4.27[cm]

But we need the radius, and we know that the radius is equal to the half of the diameter.

Rt = 3.175 [cm]

Rg = 2.135 [cm]

Now replacing this values in the given equation:

V = \frac{4}{3} *\pi *r^{3}\\ V_{tennis}= \frac{4}{3} *\pi *(3.175)^{3}\\ V_{tennis}= 134.06[cm^3]\\\\ V_{golf}= \frac{4}{3} *\pi *(2.135)^{3}\\V_{golf}= 40.76 [cm^3]
