If the it took the object travelling at 25m/s 1 second to travel a quarter of the circle, it means a quarter of the circle is 25m (it travels 25m in one second).
If the quarter of the circle is 25m than the circumference of the circle is 100m.
We want to calculate the radius of the circle.
Remember that the equation for finding the circumference contains the radius. We can use that equation to solve for the radius.
Circumference = 2πr
π = pi or 3.1415...... ( a number )
r = radius
Since we know the circumference, plug it in.
100m = 2πr
solve for the radius by isolating r.
100m/2π = r
r = radius = 100m/2π = 50m/π = 50/π meters
<h2>
Answer: Radius = 50/π meters</h2>
Answer:
Explanation:The average human adult has more than 5 liters (6 quarts) of blood in his or her body. Blood carries oxygen and nutrients to living cells and takes away their waste products. It also delivers immune cells to fight infections and contains platelets that can form a plug in a damaged blood vessel to prevent blood loss
Salt, in chemistry, substance produced by the reaction of an acid with a base. A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. Hope this helps!!!
In the absence of an external force, a moving object will move with a constant velocity in a straight line.
This is according to Newton's first law of motion that states: An object continues to be in its state of rest or uniform motion and in the same direction not unless acted upon by an external force to change that state.
For this case we have:
A surface of water is hit with a ruler every 0.2 seconds. If the wavelength of the wave that occurs is 3.5 cm, calculate:
a. The frequency of the wave.
b. The velocity of wave propagation.
By definition, we have that the velocity of propagation of the wave is given by:
Where:
w: is the wavelength
f: It is the frequency
On the other hand, we can find the frequency:
Thus, the velocity of propagation of the wave is:
Answer:
