Answer:
A,
Explanation:
im going to choose a because they should probably still water it so it doesn’t die at least until it grows or gets a little bigger.
I believe the answer should be C!
Only Condition for Resonance is-
It occurs when the first object is vibrating at the natural frequency of the second object. It always result into a big vibration/loud sound.
Resonance is process by which a vibrating system or an external force drives another system to oscillate with greater frequencies at specific frequencies called resonant frequencies. At resonance frequencies, small periodic driving forces have capacity to produce large amplitude oscillation.
∴ In given scenarios, the case which accurately describes a condition in which resonance can occur is-
C. A pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends.
Answer:
Angular speed will reach 6.833rad/s before the coin starts slipping
Explanation:
There is no question but I'll asume the common one: Calculate the speed of the turntable before the coin starts slipping.
With a sum of forces:
At this point, friction force is maximum, so:
Solving for V:
V=1.025 m/s
The angular speed of the turntable will be:
ω = V/R = 6.833 rad/s This is the maximum speed it can reach before the coin starts slipping.
Given :
Cindy's house is 600 meters away. Jim runs as hard as he can with a speed of 5.3 m/s and Harry jogs with a speed of 8.2 m/s.
To Find :
How long will Harry have to wait for Jim when he gets to Cindy's house.
Solution :
Time taken by Harry to reach Cindy's house :
Time taken by Jim to reach Cindy's house :
Time taken by Harry to wait for Jim is :
T = = 113.21 - 73.17 s = 40.04 s
Hence, this is the required solution.
