Answer:

Reduce the friction at the surface

Explanation:

If you can reduce the friction between the load and the plane less effort will be required as you are not having to apply effort to overcome friction.

A U-tube is open to the atmosphere at both ends. Water is poured into the tube until the water column on the vertical sides of t

zmey [24]

Answer:

The value is $\Delta h = 0.003 \ m$

Explanation:

From the question we are told that

The height of the water is $h_1 = 10 \ cm = 0.10 \ m$

The density of oil is $\rho_o = 950 \ kg/m^3$

The height of oil is $h_2 = 6 \ cm = 0.06 \ m$

Given that both arms of the tube are open then the pressure on both side is the same

$P_a = P_b$

=> Here

$P_a = P_z + \rho_w * g * h$

where $\rho_w$ is the density of water with value $\rho_w = 1000 \ kg/m^3$

and $P_z$ is the atmospheric pressure

and

$P_b = P_z + \rho_o * g * h_2$

=> $P_z + \rho_w * g * h = P_z + \rho_o * g * h_2$

=> $\rho_w * h = \rho_o * h_2$

=> $h = \frac{950 * 0.06 }{1000}$

=> $h = 0.057 \ m$

The difference in height is evaluated as

$\Delta h = 0.06 - 0.057$

$\Delta h = 0.003 \ m$

When you're 10 or 20 miles away from the origin of an earthquake, the P-waves get to you a little bit before the S-waves. Which

zvonat [6]

Explanation:

P, Primary, or Compressional waves travel the fastest (~6 km/sec in the upper crust). They cause the matter to oscillate forward and backward, parallel to the motion of the seismic wavefront. P waves push (compress) and pull (dilate) the rock that they pass through.

an object with a mass of 5kg is moving with an initial velocity of 20m/s.the object accelerates at a rate of 15m/s/s for 8s.what

Alinara [238K]

It doesn't matter what the object's initial velocity is, or how long
the acceleration lasts. All that matters is the object's mass and
acceleration.

Force = (mass) x (acceleration) =

(5kg) x (15 m/s²) =

75 kg-m/s² = <em>75 newtons .</em>
