Answers

Depends on the graph, but the answer is likely the slope. The greater the slope, the greater the change in whatever is being graphed. In this case velocity vs time.

The radius of the sphere is (4.3+-0.1)cm. the % error in the vol is???

Answers

The maximum error in its radius is (0.1) / (4.3) .

We know that volume is proportional to (radius)³, so the error in
volume is proportional to (error in radius)³ .

[ 1 + 0.1/4.3 ]³ = 1.0714

The max volume error is 7.14 % 

A bowling ball rolls off the edge of a flat roof at a velocity of 16 m/s. What is the actual speed of the ball one second later?

Answers

Answer:

The horizontal velocity is constant at 16 m/s.

After 1 sec since v = a t then 9.8 m/s^2 * 1 sec = 9.8 m/s for the vertical velocity

V = (Vx^2 + Vy^2)^1/2 = (16^2 + 9.8^2)^1/2 = 18.8 m/s

What is kinetic theory of gases?

A huge number of submicroscopic particles, including atoms and molecules, are used in the kinetic theory of gases, a theoretical model, to characterize the molecular makeup of the gas.

The idea also states that gas pressure results from particles slamming into one another and the container walls. In addition to defining physical characteristics like temperature, volume, and pressure, kinetic theory of gases also defines transport characteristics like viscosity, thermal conductivity, and mass diffusivity.

It essentially explains every characteristic connected to the tiny phenomenon. The idea is significant because it aids in creating a relationship between macroscopic properties and tiny phenomena.

this question is a critical question. as we all know, when energy is added to any state of water, the particles move faster. and when energy is taken away from any state of water, the particles reduce speed. same with the particles of air. when energy is added; they move faster. when energy is removed; they move slower. so the answer is they move faster
