Two blocks, of mass m and 2m, are initially at rest on a horizontal frictionless surface. A force F is exerted individually on e

ach block, as shown above. The graph shows how F varies with time t. Which block has the greatest average power provided to it between t = 0 s and t = 3 s?

The block has the greatest average power provided is bock m.

<h3>What is instantaneous power?</h3>
  • This is the product of force and velocity exerted on an object.

Mathematically instantaneous power is calculated as;

P = Fv

where;

  • F is the applied force
  • v is the velocity

Both blocks (m and 2m) will experience the same force but different velocity.

The smaller block (m) will experience greater velocity.

Thus, the block has the greatest average power provided is bock m.

U need to set up n solve the general eqn for simple harmonic motion:
x" = -(k/m)x

solution is x(t) = (x0)*cos(wt) + (v0/w)*sin(wt)
where w=sqrt(k/m), x0 is x-position at t=0 and v0 is vel at t=0
u already calculated f in Q.2 and w = 2*pi*f
x0 is 0 as it starts at eqm
v0 is given at 5.1

so u have x(t)

vel is given by x'(t) = (x0)*(-w)*sin(wt) + (v0/w)*w*cos(wt)

substitute t=0.32, x0=0, v0=5.1 n w in the above, u can solve for v at t=0.32.

A row of seats is parallel to a stage at a distance of 90 m from it. At the center and front of the stage is a diffraction horn
Serggg [28]

Answer:

distance between seats = 2*11.10 = 22.20 m

Explanation:

seats row is parallel to a stage with a distance d = 90 m

doorway width = 0.070 m

speaker frequency = 4.00 * 10^4 Hz

Speed of sound = 343 m/s

tone will be heard at

sin \theta = \frac{\lambda}{D}

we know that v =\lambda d

so

sin\theta = \frac{v}{dD}

              = \frac{343}{4.00 * 10^4*0.070}

sin\theta = 0.1225

\theta = 7.036 degree

tan\theta =\frac{x}{d}

[tex]x = d*tan\theta = 90*0.1234 = 11.10 m

distance between seats = 2*11.10 = 22.20 m

Metamorphic rock occurs when you take any other type of rock and put them under ________ and ______________, and they twist and
GrogVix [38]

Answer:

This question appear incomplete

Explanation:

This question appear incomplete because of the absence of options. However, metamorphic rocks are rocks that are formed from other pre-existing rocks under heat and pressure (both are usually high), causing them to twist and melt together. Metamorphism simply means a change in form of something and that's what happens here also.
