Answer:
Whats The Question Exactly (Ill Edit This To Fit It)
Explanation:
Answer:
<h2>
Answer⤵</h2><h3><u>i</u><u>)</u><u>The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane. </u></h3><h3><u>i</u><u>i</u><u>)</u><u>The second law of reflection states that the angle of reflection is equal to the angle of incidence. Both angles are measured with respect to the normal to the mirror.</u></h3>
Answer:
Velocity is 3.02 m/s at an angle of 53.13° below X-axis.
Explanation:
Let unknown velocity be v.
Here momentum is conserved.
Initial momentum = Final momentum
Initial momentum = m x 6i + m x 0i = 6m i
Final momentum = m x (4.8cos 30 i + 4.8sin 30 j) + m x v = 4.16 m i + 2.4 m j + m v
Comparing
4.16 m i + 2.4 m j + m v = 6m i
v = 1.84 i - 2.4 j
Magnitude of velocity
Direction,
Velocity is 3.02 m/s at an angle of 53.13° below X-axis.
Answer:
So the minimum force is
32.2Newton
Explanation:
To solve for the minimum force, let us assume it to be F (N)
So
F=mgsinA
But
=>>>> coefficient of static friction x (F + mgcosA
=>3 x 9.8 x sin35 = 0.3 x (F + 3 x 9.8 x cos35)
So making F subject of formula
F + 24.0 = 56.2
F = 32.2N
Answer:
Your answer doesn't provide that much evidence that much. But, I try to help you find the answer. I think your answer is the number of cycles per second perceived by the human ear. Well, Pitch is basically our sound of our voice. Sometimes, Our voice can even go 'higher' or 'lower'. Let me give you a example. If we screen our voice go higher than before and sometime it can even pitch. And, Sometime when we talk lower our voice give us a lower tune.
Good Luck!!~
