major must continuously exert 1.16 ✕ 102 N of force to insert a dry steel piston as it slides into a steel cylinder. What is the normal force (in N) between the piston and cylinder? A.) (Enter the magnitude.) B.)What force (in N) would he have to continuously

Consider the following section of pipe. The velocity of water (Pwater h₁ m S V₁ = 2.9 h₁ = 3.2 m V₂ = 6.7 h₂ = 1.9 m m S Point 1 = 1000 kg ) and height are given for two different points in the pipe. Use this information to answer the following questions. m What is the ratio of the cross-sectional area at point 1 to the cross-sectional area at point 2? A₁ A₂ What is the difference in pressure between points 1 and 2? (Find P2 - P₁. Include a negative sign if that's what you calculate.) P2 - P1 = Pa Which direction is the water flowing through the pipe? Point 2 h₂

P Some fish have a density slightly less than that of water and must exert a force, by swimming, to stay barely submerged. What magnitude of force, in newtons, must an 82-5-kg grouper exert to stay submerged in salt water (with density 1025 kg/m³) if its body density is 1015 kg/m³?

A trough is filled with a liquid of density 865 kg/m³. The ends of the trough are equilateral triangles with sides 4 m long and vertex at the bottom. Find the hydrostatic force (in N) on one end of the trough. (Use 9.8 m/s² for the acceleration due to gravity.) N

A 5.40 kg object is released from rest while fully submerged in a liquid. The liquid displaced by the submerged object has a mass of 3.50 kg. How far does the object move in 0.300 s, assuming that it moves freely and that the drag force on it from the liquid is negligible? m

When an open-faced boat has a mass of 5250 kg , including its cargo and passengers, it floats with the water just up to the top of its gunwales (sides) on a freshwater lake.

Drag Force: A spherical particle of radius 5.9 cm and a mass of 229 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) 1 The position of the particle is given by x (t) = In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 17.4 m/s, and the constant b is 0.4 m-1. (b) What is the velocity of the particle after 2.9 seconds? (c) What is the acceleration of the particle after 2.9 seconds?

A thin-walled hollow spherical ball of mass 0.4 kg and radius 0.1m is filled with alcohol of density 800 kg/m3. It is released from the bottom of a pool filled with water. a. sketch a FBD for the ball b. write out newtoon's 2nd law equation c. Find the acceleration of the ball

Some jellyfish can eject stingers with remarkable force and speed. One species does this by building up a 15 MPa gauge pressure that pushes against the base of a 2.0-μm-diameter stylet, forcing it outward.a. What force does the excess pressure exert on the stylet?b. The mass set into motion is a tiny 1.0 × 10-12 kg. What is the resulting acceleration?
