Answer:
The answer is louder sounds. Resonance is the process, in which a system vibrates with increasing amplitudes, at specific frequencies of excitation. Resonance results in louder sounds. ... This is because of the surrounding environment, resonates with the cavity of the shell .
Explanation:
Final speed after collision with the wall
before collision the speed of ball initially
time taken for the collision
now as per the formula of acceleration we know that
now plug in all values in it
so acceleration is - 5 m/s/s for above situation
Answer: Option A; 9.8 m/s^2
Explanation:
When an object is in the air, and there is no air resistance acting on the object, the only force that will act on the object is the gravitational force (on the vertical axis).
Then, if the only force acting on the object is the gravitational force, the acceleration of the object will be equal to the gravitational acceleration.
We know that the gravitational acceleration is equal to:
g = 9.8m/s^2
Then the acceleration on the vertical axis will be equal to:
a(t) = 9.8m/s^2
The correct option is the first one:
A. 9.8 m/s^2
Answer:
sorry- but what........?!
Explanation:
The temperature must be hot enough to allow the ions of deuterium and tritium to have enough kinetic energy to overcome the Coulomb barrier and fuse together. The ions must be confined with a high ion density to achieve a suitable fusion reaction rate.
