Answer:
All knowledge is learned through the senses, perceptions.
Some knowledge is learned by personal experience, personal perception, some knowledge can be learned by reading about the experiences of others.
There is no knowledge that is not learned by either (a) personal experience, perception, or (b) by learning from the experiences and perceptions of others.
The acceleration of a different speck of dust is 40 m/s.
Since the radius is been given as double and angular velocity will be constant, we can calculate the centripetal acceleration as
a = (2r)ω²
If we substitute the given values of r= 2r , and ω²= 20m/s.
Then we have
Therefore, acceleration of a different speck of dust is 40 m/s.
<h3>What is centripetal acceleration?</h3>
centripetal acceleration can be regarded as acceleration of a body that is traversing a circular path.

Answer:
(15/17 = sin ∠ JLK)
(first option listed)
Explanation:
the "sin ∠ JLK" is what we can simply think of as the inside measurement of angle/corner L. (L is the letter in the middle of ∠ JLK , and if you imagine drawing a line from J to L to K, you would see that the only angle you formed both sides of is corner L)
so, we are looking for the sin of L.
(SOH CAH TOA)
we know that
sin = opposite / hypotenuse
However, we do not have the opposite value of this triangle <em>yet. </em>
-----
we can solve the length of the opposite side with the Pythagorean theorem:
a² + b² = c²
8² + b² = 17²
64 + b² = 289
- 64 - 64
b² = 225
√b² = √225
b = 15
----
so, to solve for sin L,
(sin = opposite / hypotenuse)
we should divide the opposite (15) over the hypotenuse (17)
so, 15 / 17 = sin L
(15/17 = sin ∠ JLK)
Answer:
0, or 1
Explanation:
Depends on if you asked for your blood type, which they will HAVE to draw your blood. Otherwise, any regular visit to the doctor will not require to draw your blood if it's a checkup. Though for certain visits/testing blood may be required to get drawn once- unless there is a problem during the drawing process. Hope this helped!
