Answer:

Usage of Infrasound are discussed below.

Explanation:

Infrasound waves are sound waves so low in frequency that even a human ear can not able to hear or detect them.

Usage of Infrasound

The uses of Infrasound waves are for Medical purposes.
The Infrasound waves are used in monitoring atmospheric activities.
The Infra sound waves are used in Forecasting natural disasters.

A particle moves along the x axis. It is initially at the position 0.180 m, moving with velocity 0.060 m/s and acceleration -0.3

shusha [124]

Answer:

$x_2 = -2.3356$

$v = -1.384 \ m/s$

Explanation:

From the question we are told that

The initial position of the particle is $x_1 = 0.180 \ m$

The initial velocity of the particle is $u = 0.060 \ m/s$

The acceleration is $a = -0.380 \ m/s^2$

The time duration is $t = 3.80 \ s$

Generally from kinematic equation

$v = u + at$

=> $v = 0.060 + (-0.380 * 3.80)$

=> $v = -1.384 \ m/s$

Generally from kinematic equation

$v^2 = u^2 + 2as$

Here s is the distance covered by the particle, so

$(-1.384)^2 = (0.060)^2 + 2(-0.380)* s$

=> $s = -2.5156 \ m$

Generally the final position of the particle is

$x_2 = x_1 + s$

=> $x_2 = 0.180 + (-2.5156)$

=> $x_2 = -2.3356$

One of the largest helicopters in the world weighs 1 x 10^6 N. If you were to place this helicopter on a large piston of a hydra

zhuklara [117]

This question involves the concepts of Pascal's Law and Pressure.

The required to be applied to the small piston is "5000 N".

According to Pascal's Law, the pressure applied to an incompressible fluid medium is equally transmitted in all directions. Hence, the pressure on each piston must be equal to each other:

$P_1=P_2\\\\\frac{F_1}{A_1}=\frac{F_2}{A_2}$

where,

F₁ = Force on small piston = ?

A₁ = Area of smaller piston = 0.7 m²

F₂ = Force on larger piston = weight of helicopter = 1 x 10⁶ N

A₂ = Area of larger piston = 140 m²

Therefore,

$F_1=\frac{10^6\ N}{140\ m^2}(0.7\ m^2)$

a car of mass 800 kg is travelling at 12m/s the car accelerates over a distance of 240 m there force causing this acceleration i

alisha [4.7K]

Answer:

See below

Explanation:

Force X distance = work

200 N * 240 m = 48 000 N-m = 48 000 j

F = ma

200 = 800 a

a = 1/4 m/s^2

d = v t + 1/2 a t^2

12 m/s t + 1/2 1/4 m/s^2 t^2 = 240

shows t = 17 sec (via Quadratic Formula)

final velocity = 12 + at = 12 + 1/4(17) = 16.26 m/s
