<h3><u>Answer;</u></h3>

Velocity

<h3><u>Explanation;</u></h3>

Instantaneous acceleration is how fast a<u> velocity</u> is changing at a specific instant.

  • <u><em>Acceleration is the change in an object's velocity divided by time.</em></u>
  • <u><em>Instantaneous acceleration is the acceleration of an object at a specific moment of time or instant. </em></u>
  • instantaneous acceleration is the instantaneous change of velocity over an instance of time.
  • It is given by the formula;<em><u> a = dv/dt; where dv is the derivative of v , and dt is the derivative of t.</u></em>

T/F if you were conducting this study, what other questions would you want to ask to ensure both the external and internal valid
ryzh [129]

whether or whether the conclusions apply to people whose location and circumstances differ from those of the study's participants need to asked to ensure both the external and internal validity of your results

<h3>How can external validity be guaranteed?</h3>

Broad inclusion criteria that produce a study group that more closely mimics real-life patients and, in the case of clinical trials, selecting interventions that are practical to implement can both boost external validity.

<h3>What steps would you take to make sure your study is reliable and valid?</h3>

The development of a solid study design, the selection of suitable methodologies and samples, and the meticulous and consistent execution of the research are all necessary for the reliability and validity of your findings.

Satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an
Volgvan

Answer:

0.63

Explanation:

We are given that

Radius of earth,R_E=6370 km

Radius of orbit A,R_A=7590+6370=13960 km

Radius of orbit B,R_B=6370+15800=22170 km

We have to find the ratio of the potential energy of satellite B to that of satellite A in orbit.

Potential energy of orbit A=U_A=-\frac{GM}{R_A}=-\frac{GM}{13960}

Potential energy of orbit  B=U_B=-\frac{GM}{R_B}=-\frac{GM}{22170}

\frac{U_B}{U_A}=\frac{13960}{22170}=0.63

Hence,the ratio of the potential energy of satellite B to that of satellite A in orbit=0.63

Which two statements describe a situation that would result in a change to landforms on Earth’s surface.
Lilit [14]

Answer:

A. A volcano erupts on a small island.

C. Flooding loosens dirt and rocks along a hillside.

Explanation:

Tectonic activities and mass wasting will greatly lead to a change in land forms on earth's surface.

When a volcano erupts on a small island, a change in landform often results. Also, flooding can lead to changes in land form.

  • Volcanic eruptions generally adds new materials to the earth surface.
  • Magma that reaches the surface called lava deposits rock materials unto the surface.
  • During an extensive period of flooding, materials are carried from one place to another and this greatly sculpts the surface of the earth.

A 1.25 kg block is attached to a spring with spring constant 17.0 N/m . While the block is sitting at rest, a student hits it wi
Free_Kalibri [48]

Answer:

The amplitude of the subsequent oscillations is 13.3 cm

Explanation:

Given;

mass of the block, m = 1.25 kg

spring constant, k = 17 N/m

speed of the block, v = 49 cm/s = 0.49 m/s

To determine the amplitude of the oscillation.

Apply the principle of conservation of energy;

maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced

K.E_{max} = U_{max}\\\\\frac{1}{2} mv^2 = \frac{1}{2} kA^2\\\\where;\\\\A \ is \ the \ maximum \ displacement = amplitude \\\\mv^2 = kA^2\\\\A^2 = \frac{mv^2}{k} \\\\A = \sqrt{\frac{mv^2}{k}} \\\\A =  \sqrt{\frac{1.25\  \times \ 0.49^2}{17}} \\\\A = 0.133 \ m\\\\A = 13.3 \ cm

Therefore, the amplitude of the subsequent oscillations is 13.3 cm
