Neko [114]

Frequency (f) = 500 hz (SI)
Velocity (V) = 1250 m/s (SI)
Wavelength (Lambda) = ? meters

$v = \lambda \times f$
$1250 = \lambda \times 500 \\ \lambda = 1250 \div 500 \\ \lambda = 2.5 \: meters$

the deepest point in the sea is 100m below sea level .what arr the water pressure at this depth and the total pressure due to wa

fomenos

The water pressure at this depth and the total pressure due to water and atmosphere are 10.3 x 10⁵ Pa and 11.31× 10⁵ Pa.

<h3>What is pressure?</h3>

The pressure is the amount of force applied per unit area.

Atmospheric pressure, Patm =1.01×10⁵ Pa

Density of water, ρ=1030 kg/m³

Depth, h=100 m

Pressure =ρgh

P = 1030×10×100

P = 10.3 x 10⁵ Pa.

Total pressure, P=Po +ρgh

P=1.01×10⁵ + 1030×10×100

P=11.31× 10⁵ Pa

Hence, total pressure is 11.31× 10⁵ Pa.

Raindrops are falling straight downward. When observed from a car traveling at 55.0 mi/h, the drops streak the side window at an

GREYUIT [131]

Explanation:

It is given that,

Speed of the car, $v_c= 55\ mi/h = 24.58\ m/s$

The drops makes an angle of 60 degrees with the vertical. The attached figure shows the whole description. $v_r$ is the speed with which the drops are falling.
