Question 3
GREYUIT [131]

Based on scientific data, the stone is accelerated at approximately 10 m/s^2.

<u>Given the following data:</u>

  • Weight = 5 Newton
  • Height = 44 meters.

<h3>What is gravity?</h3>

Gravity can be defined as a force of attraction that controls the movement of the planets such as Earth around the Sun.

This ultimately implies that, gravity is a universal force of attraction that acts between all objects or matter that are having both mass and energy, and can occupy space.

<h3>Gravity on planet Earth</h3>

Furthermore, the gravity near the Earth's surface generally makes it possible for all physical objects such as stones to possess weight and experience a free fall.

According to astronomical records, the acceleration due to gravity for an object experiencing a free fall near the Earth's surface is 9.8 m/s^2.

In this scenario, the stone is accelerated at approximately 10 m/s^2.

Calculate the average value of an AC signal with a peak amplitude of 10V and a frequency of 10 kHz.
Solnce55 [7]

Answer:

V(average)=6.37 V

Explanation:

Given Data

Peak Voltage=10V

Frequency=10 kHZ

To Find

Average Voltage

Solution

For this first we need to find Voltage peak to peak

So

Voltage (peak to peak)= 2× voltage peak

Voltage (peak to peak)= 2×10

Voltage (peak to peak)= 20 V

Now from Voltage (peak to peak) formula we can find the Average Voltage

So

Voltage (peak to peak)=π×V(average)

V(average)=Voltage (peak to peak)/π

V(average)=20/3.14

V(average)=6.37 V

Jack rolled a marble down a ramp and recorded the potential energy and kinetic energy of the marble at different positions on th
mote1985 [20]

Answer: D

Height of marble from ground

Explanation:

From the formula of kinetic energy and potential energy,

K.E = 1/2mv^2

While

P.E = mgh

From all the parameters given from the question. You can see that mass is constant, acceleration due to gravity is also constant.

Independent variable must be a value that can varies.

Since Jack rolled a marble down a ramp and recorded the potential energy and kinetic energy of the marble at different positions on the ramp to see the effects on both energies.

This different position must be the height which will produce an effect on the potential and kinetic energy of the marble.

Independent variable always provides an effect for dependent variable. Which are kinetic energy and potential energy in this case.

Height of marble from ground is the right answer.
