Answer:
tension
Explanation:
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration.
Answer:
Acceleration is rate of change of velocity.
The equation of turtle's position as a function of time is given by:
Differentiate the above equation to find the velocity as a function of time:
Differentiating further, we would get the equation for acceleration:
Therefore, initial acceleration is

4) The lost value is $4500.
5) The values in a $ are Dependent variable in the graph.
6) Time(year) is inversely proportional to the values in $.
<u>
Explanation:

4) To calculate a loss between 2005 and 2006 we will find the value on the y-axis for 2005(which is on the x-axis) from the graph and subtract it by the value on the y-axis for 2006(which is on the x-axis) from the graph.
loss between 2005 and 2006 = $14500-$10000
= $4500
Percentage of loss is 31.03%
5) A dependent variable is a variable being tried and estimated in a logical test. The dependent variable in the graph is the value of the car that is given in the Dollar($). We can see that by the increase of the time there is an effect on the value of the car and the dependent variables are taken on the y-axis.
6) From the graph, It is shown that with an increase in time(year) the value of Sarah's car decreases and with the decrease in time its value increases. So it is clear that time is inversely proportional to the value of the car. By every passing year, the value of the car decreases.
Answer:
Work is the energy required to move an object from one point to another. while power is the energy transferred per unit time.
Energy can also be defined as the ability to do work.
Answer:
The gravitational acceleration is 5.03 m/s² on the surface of the planet.
Explanation:
Frequency:
The number of complete oscillation per unit second is called frequency.
Angular frequency:
Angular frequency is the product of the oscillation frequency and the angle thought which the object moves.
Angular velocity
Given that,
Number of oscillation= 247, time= 793 s, length of the pendulum=1.31 m
Hz.
Angular velocity
=1.96 rad/s
We know that,
g= gravitational force of the planet
= length of the pendulum
= angular velocity
m/s²
= 5.03 m/s²
The gravitational acceleration on the surface of the planet is 5.03 m/s².
