Instead it reverses direction and ends down on the ground below the window. Since the brick didn't break the glass, we know: О The force of the brick on the glass > the force of the glass on the brick. О The force of the brick on the glass the force of the glass on the brick. = О The force of the brick on the glass < the force of the glass on the brick. О The brick didn't slow down as it broke the glass.arrow_forwardAlexandra (wearing rubber boots for traction) is attempting to drag her 32.6-kg Golden Retriever across the smooth ice by applying a horizontal force.

Review the data from the lab and determine whether your data is within standard deviations. Report, using numerical values, whether your data for each angle is within standard deviations. An acceptable margin of error typically falls between 4% and 8% at the 95% confidence level. Review your data for each angle to determine whether the margin of error is within an acceptable range. Report with numerical values, whether your data for each angle is within an acceptable margin of error. Can you help explain what my data means in terms of the standard deviation and the ME?

The displacement of the string as a function of time is graphed in (Figure 1) for particles at x = 0 and at x = 0.0900 m. You are told that the two points x = 0 and x = 0.0900 m are within one wavelength of each other. If the wave is moving in the +x-direction, determine the wavelength. If instead the wave is moving in the -x-direction, determine the wavelength. Please show all stepsarrow_forward
