Water is flowing through a channel that is 12m wide with a

Alexus [3.1K]

Answer:

Velocity from second channel will be 1.6875 m/sec

Explanation:

We have given width of the channel , that is diameter of the channel 1 $d_1$ = 12 m

So radius $r_1=\frac{d_1}{2}=\frac{12}{2}=6m$

Speed through the channel 1 $v_1=0.75m/sec$

Width , that is diameter of the channel 2 $d_2=4m$

So $r_2=2m$

From continuity equation

$A_1v_1=A_2v_2$

$\pi \times 12^2\times 0.75=4\times \pi\times 4^2\times v_2$

$v_2=1.6875m/sec$

So velocity from smaller channel will be 1.6875 m /sec

Hi please answer and show your work

jek_recluse [69]

Answer:

$\huge\boxed{\sf P.E. = 240\ MJ}$

$\huge\boxed{\sf K.E. = 19.6\ MJ}$

Explanation:

<u>Given:</u>

Mass = m = 200,000 kg

Vertical Distance = h = 120 m

Speed = v = 14 m/s

Acceleration due to gravity = g = 10 m/s²

<u>Required:</u>

1) Gravitational Potential Energy = P.E = ?

2) Kinetic Energy = K.E. = ?

<u>Formula:</u>

1) P.E. = mgh

2) K.E. = $\displaystyle \frac{1}{2} mv^2$

<u>Solution:</u>

1) P.E. = (200,000)(10)(120)

P.E. = 240,000,000 Joules

P.E. = 240 Mega Joules

P.E. = 240 MJ

2) K.E. = 1/2 (200000)(14)^2

K.E. = (100000)(196)

K.E. = 19,600,000 Joules

K.E. = 19.6 MJ

$\rule[225]{225}{2}$

Hope this helped!

If you are trying to get ketchup out of the bottle, the best way to do it is to turn the bottle upside down and give the bottle

Igoryamba

Answer:

Explanation:

A body remains at rest or in motion unless or until an external force is applied. This is called Law of Inertia

Now When ketchup bottle is turned upside down and smack is applied to it, it causes the ketchup to start moving thereby disturbing its motion of rest and provide its motion.

And according to the first law state of rest is broken by applying an external force.

I notice the wheels on my bicycle spin in a circular motion as I am pedaling. I know that the

kherson [118]

Answer:

Acceleration, a = 750m/s²

Explanation:

Given the following data;

Radius, r = 0.31m

Velocity, v = 15m/s

To find the centripetal acceleration;

$Acceleration, a = \frac {v^{2}}{r}$

Substituting into the equation, we have;

$Acceleration, a = \frac {15^{2}}{0.31}$

$Acceleration, a = \frac {225}{0.31}$

Acceleration, a = 750m/s²

Therefore, the centripetal acceleration of the bike wheel is 750m/s².
