Reverberation is the persistence of sound due to repeated reflection, where an echo may be heard. We can reduce the reverberation by covering the roof and the wall of the hall with sound absorbing materials like <span>Acoustical panels, Noise and sound isolation foams, MLV ( Mass Loaded Vinyl) Soundproofing foam, etc.</span>
Answer:
Always do it on my own
So I gotta get through it
And the only thing I know
Is to love what I'm doing
Never give up, never slow
Till I finally prove it
Never listen to the no's
I just wanna keep moving
Keep my head up when I act
Head up, that's a fact
Never looking back
I'ma keep myself on track
We Know, Power rating (P) = Voltage (V) × Current (I)
Here, P = 180 w
V = 110 v
Substitute their values into the expression:
180 = 110 × I
I = 180 / 110
I = 1.64 A
So, Your Final answer would be 1.64 Ampere
Hope this helps!
Answer: 299,427.84 J, 99,809.28 W
Explanation: we will assume the acceleration of the body to be constant, hence newton's laws of motion is applicable.
From the question
Force (f) = 75 N
Mass of object (m) = 6kg
Initial velocity (u) = 20 m/s
Final velocity (v) = 58 m/s
Time taken (t) = 3s
Recall that
F = ma
75 = 6a
a = 75/6 = 12. 5 m/s²
We need to get the distance before we can get the work done.
Recall that v² = u² + 2as, where s = distance covered
56² = 20² + 2(12.5)s
56² - 20² = 25s
2736 = 25s
s = 2736/ 25 = 109.44m
Work done = force × distance
Work done = 75 × 109.44 = 299,427.84 j
Power = work done / time
Power = 299,427.84 / 3
Power = 99,809.28 W
