Answer:

A. Objects 1 and 2 will not move, and objects 3 and 4 will accelerate

upward.

Explanation:

A is correct as the weight in Objects 1, and 2 is greater than the person's push force; however it is on the ground meaning it is at it's stable state meaning the box couldn't be moved downwards anymore. And The newtons in 3 and 4 are the same

B is incorrect as Object 3 and 4 has a less Newton weight than newton force

C is incorrect as Object 1 and 2 has a greater Newton weight than newton force

D is incorrect as Object 1 and 2 wouldn't move downwards

Hope this helps!

Answer: A. Objects 1 and 2 will not move, and objects 3 and 4 will accelerate upward.

Explanation:

Because objects 1 and 2 require more force in order to move, they will stay motionless.

Correct me if I am incorrect.

Answer:

a) Θ = ω₀*t + ½αt² To complete first revolution 2π rads = 0*t + ½αt² and to complete the first and second combined 4π rads = 0*t + ½α(t+0.810s)² Divide second by first: 2 = (t + 0.810s)² / t² This is quadratic in t and has roots at t = -0.336 s ← ignore and t = 1.96 s ◄ b) Use either equation from above: 2π rads = 0*t + ½α(1.96s)² α = 3.27 rad/s² ◄ Hope this helps!

An object of mass 100kg is raised 2m above the ground using an Inclined Plane of length 10m calculate the effort parallel to inc
MArishka [77]

Answer:

Slope = 2 m / 10 m = 1/5

For every  5 m of effort the object will be raised 1 m

W = work done on object = M g h      increase in PE of object

E S = W      where E is effort and S the distance thru which the effort acts

E S = M g H

E = 100 kg * 9.8 m/s^2 * 2 m / 10 m = 196 kg m / s^2 = 196 N

Check: total work = 2 * 9.8 * 100 = 1960 J

Force Needed = 1960 J / 2 m = 980 Newtons

Mechanical advantage = 980 / 196 = 5   as one would expect since the object is raised 1 m for every 5 m of force input

diamong [38]

Answer

speed of the molecules

s₁ = v t

when velocity is doubled

s₂ = (2 v)t

   = 2 s₁

they will hit the wall of container two times as often.

the momentum of molecule

p₁ = mvr

p₂ = m(2v)r = 2(mvr)

    = 2 p₁

the momentum change is two times as great.

force is change in momentum

Δp = F(Δt)

mv-(-mv) = 2 mv

F = \dfrac{2 mv}{\Delta t}

F α v

therefore average force impart to the wall on each collision is two times

p = \dfrac{F_{total}}{A}

p = \dfrac{Nmv^2}{3LA}

p α v²

here the velocity is doubled it means pressure becomes four times.
