Answer:

a=500/50=10 m/s^2

Explanation:

f=m•a a=f/m

a=500/50= 10 m/s^2

Suppose that the separation between two speakers A and B is 4.80 m and the speakers are vibrating in-phase. They are playing ide

Hatshy [7]

Answer:

$X=8.44m$

Explanation:

From the question we are told that

Distance b/w A&B $x=4.80m$

Frequency $f=134Hz$

Sound speed $v=343m/s$

Generally the equation for wavelength is mathematically given as

$\lambda=v/f$

$\lambda/2=1/2*v/f$

$\lambda/2=1/2*\frac{343}{135}$

$\lambda/2=1.27037037$

Generally the destructive interference X is mathematically given by

$\sqrt{4.8^2 +X^2} -X=1.27037037\\$

$23.04+BC^2=X^2+1.613+2.54*X$

Therefore the destructive interference is

$X=8.44m$

Two pans of a balance are 46.3 cm apart. The fulcrum of the balance has been shifted 0.633 away from the center by a dishonest s

soldier1979 [14.2K]

distance of each pan from the center or fulcrum is given as

$r = 23.15 cm$

now if dishonest shopkeeper shifted it by 0.633 cm from center

so distance on each side is given as

$d_1 = 23.15 - 0.633 = 22.52 cm$

$d_2 = 23.15 + 0.633 = 23.78 cm$

now the weight is balance as

$W_1d_1 = W_2d_2$

$W(22.52) = W_2(23.78)$

now we will have

$W_2 = 0.95W$

now we can find the percentage change as

$percentage = \frac{W - W_2}{W} \times 100$

$percentage = 5%$

What quantity is multiplied by the hydraulic lift system of a dump truck?

kogti [31]

funny, actually, i'm a hydraulic, and pneumatic cylinder, pump, and line system mechanic, and the answer is pressure.... pressure builds up from the hydraulic pump, and then transfers through hoses to extend, and contract the cylinders by filling them with hydraulic fluid, and vice versa for contracting them.

hope this helps!

Blababa [14]

You have two windlasses named X and Y. Windlass X drum diameter is 50cm and windlass Y drum diameter is 75cm. Both are hoisting a 50kg weight, Hence, X will lift faster and easier than Y

<h3>What is windlasses (winches) will lift faster?</h3>

Generally, the equation for the Torque is mathematically given as

Torque(X)=weight x radius of drum

T=50x9.81x0.25

T=122.625 Nm

For, Torque (Y)

T=50x9.81x0.375

T=183.93 Nm

Generally, the equation for the Equation of Power is mathematically given as

P= Torque * Angular velocity

Angular velocity (w)= 2 x pi x N/60

As a consequence, torque has an inverse relationship to speed. Because of this, the torque will decrease as the speed rises.

According to the previous statement, windlass X has a speed of lift that is at its maximum, but windlass Y has a speed that is very low.

Additionally, power is exactly proportional to torque, which means that the highest possible torque required the highest possible amount of energy and vice versa.

Therefore, X should raise at the highest possible speed while using the least amount of energy.

In conclusion, X will lift faster and easier than Y
