A gardener uses a water hose to fill a 30.0 L bucket. The gardener notes that it takes 1.00 min to fill the bucket. A nozzle wit

GalinKa [24]

Answer:

The distance can the water be projected is 4.51 m

Explanation:

The speed of the water in the hose is equal to:

v1 = R/A1

If we solve the continuity for v2:

v2 = R/A2 (eq. 1)

The equation for the vertical position is:

yf = yi + vy*t - (1/2)gt²

yi = 0

vy = 0

Clearing t:

$t=\sqrt{\frac{-2y_{f} }{g} }$ (eq. 2)

The equation for position is:

xf = xi + vxt = 0 + v2t = v2t (eq. 3)

Replacing equation 1 and 2 in equation 3:

$x_{f} =\frac{R}{A_{2} } \sqrt{\frac{-2y_{f} }{g} } =\frac{30}{0.5} \sqrt{\frac{(-2)*(-1)}{9.8} }*\frac{1000}{60} =451.75cm=4.51m$

Elan Coil [88]

Answer:

Explanation:

The magnetic field due to straight wire is into the square coil.

As the current in straight wire decreases the magnetic flux in the coil decreases . The induced magnetic field is into the coil.The induced current is along +y direction

Why does reflected light from the sun or moon appear as a column in the body of water as shown? how would the reflected light ap

kotykmax [81]

This column actually appears due to the body parts reflecting the light of the sun or moon to the observer.
If the body is not perfectly smooth, only parts of this body would be at the correct position to reflect the light of the sun or moon to the observer.
If the body was perfectly smooth, it would act like a mirror where you can see the full image of the sun or the moon reflected on it.

A rifle is aimed horizontally at a target 47 m away. The bullet hits the target 2.3 cm below the aim point.

inna [77]

Answer:

Is your question asking for the muzzle velocity of the bullet?

Explanation:

I will assume it does

The bullet travels horizontally to the target in the same amount of time it falls 2.3 cm from vertical rest

s = ½at²

t = √(2s/g) = √(2(0.023) / 9.8) = 0.0685118...s

v = d/t = 47/0.0685118 = 686.01242...

v = 690 m/s
