Answer:
a. distance = s x t
Explanation:
The equation we know for speed is speed = distance/time, shortened to s = d/t
If you want to find the distance, you'd rearrange the formula to make d the subject. To isolate d, multiply by t on both sides (since it's being divided on the right. This leads to
s x t = d, with d isolated on the right side.
Therefore, to find the distance an object travelled you'd use a. distance = s x t
Can you give us the options…?
The energy stored in an object when you lift it,
Should be just 2 km. - 2 km would mean it is moving in the opposite direction which come to think of it may be fine. You really can't tell.
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]](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2Ar%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%283.175%29%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20134.06%5Bcm%5E3%5D%5C%5C%5C%5C%20V_%7Bgolf%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%282.135%29%5E%7B3%7D%5C%5CV_%7Bgolf%7D%3D%2040.76%20%5Bcm%5E3%5D)
