If we start taking into account the free body diagram, we then start damping motion of a body by means of this equation:
<span>m * d^2 x/dt^2 + c* dx/dt + k* x = 0 </span>
<span>free undamped motion is when (c =0) </span>
<span>therefore </span>
<span>50* d^2 x/dt^2 + 200* x = 0 </span>
<span>w = omega = sqrt(k/m) = sqrt(200/50) = 2 </span>
<span>Then </span>
<span>A*cos(w*t) + B*sin(w*t) = x </span>
<span>find A and B using intial conditions and you will get the rest that you need. Hope this helps</span>
Answer:
The chemical reactions are depends up on the temperature. Temperature is a measure of motion of the particles, which increases by supplying thermal heat energy. According to the Kinetic molecular theory, if the reaction happens between two compounds, they collide with enough energy to overcome the activation of energy barrier.
The kinetic energy of the particles increases with increase in temperature. This results in collision being more energetic and therefore more likely to be able to overcome the activation barrier. The rate of chemical reactions increases with more collision of molecules.
<em>So, the temperature is the important parameter to increase the rate of reactions. </em>
Most events in track and field are individual except relay races. Therefore, it would probably be true.
Answer: The air entering on top of the wing speeds up. The air entering high pressure area on bottom slows down. That is why air on top moves faster.
Explanation:
Answer:
10.01 cm
Explanation:
Given that,
The time delay between transmission and the arrival of the reflected wave of a signal using ultrasound traveling through a piece of fat tissue was 0.13 ms.
The average propagation speed for sound in body tissue is 1540 m/s.
We need to find the depth when the reflection occur. We know that, the distance is double when transmitting and arriving. So,
or
d = 10.01 cm
So, the reflection will occur at 10.01 cm.
