Answer:

radius = 3 units

Step-by-step explanation:

diameter is the length of a straight line reaching from one end of the circle to the other. radius is the length of a straight line reaching from one end of the circle to the circle's midpoint. radius IS ALWAYS 1/2 of the diameter!

Please mark as brainliest :)

Answer:

BC ≈ 19.4 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos71° = $\frac{adjacent}{hypotenuse}$ = $\frac{AB}{BC}$ = $\frac{6.3}{BC}$ ( multiply both sides by BC )

BC × cos71° = 6.3 ( divide both sides by cos71° )

BC = $\frac{6.3}{cos71}$ ≈ 19.4 cm ( to 3 significant figures )

Answer:

4.77, approximately 5 cycles per minute

Step-by-step explanation:

For a loaded spring, the frequency of oscillation is given by

$f=\dfrac{1}{2\pi}\sqrt{\dfrac{m}{k}}$

where $m$ Vis the mass of the load and $k$ is spring constant.

Substituting values in the question,

$f=\dfrac{1}{2\pi}\sqrt{\dfrac{1000}{4000}}$

$f=\dfrac{1}{2\pi}\sqrt{\dfrac{1}{4}}$

$f=\dfrac{1}{2\pi}\times\dfrac{1}{2}$

$f=\dfrac{1}{4\pi}$

This value is in units of oscillations per second. To convert to oscillations per minute, we divide by $\frac{1}{60}$ or, in essence, multiply $f$ by 60.
