Answer: 0.73 g/cm3 and YES the questionable ball in this range of acceptable density
Explanation:
A cyclist can increase the speed of their bike in various ways such as, changing gears, positioning themselves properly, increase the pedalling rate
<h3>
Ways in which a cyclist can increase the speed of a bicycle</h3>
Bicycle riders could accelerate/ increase their speed in various ways
- By Changing the gears and by doing so increasing the speed
- By Positioning themselves in a streamlined manner, this is so that they become aerodynamic hence they cut across airflow.
- By increase the rate at which they are pedalling the bicycle.

Answer:
- the Thevenin equivalent circuit for the battery is uploaded below
- the battery delivered 117 watts of power to the starter motor
Explanation:
Given the data in the equation
diagram of the Thevenin equivalent circuit for the battery is uploaded below.
Current I = 10 A
Voltage 1 = 12 V
voltage 2 = 11.7 v
R = (V1 - V2) / I
R = (12-11.7)/10
R = 0.3 / 10
R = 0.03Ω
Thevenin equivalent circuit
= V2 / I = 11.7 / 10
= 1.17Ω
so, power delivered to the starter motor will be;
p = (V2)² /
P = ( 11.7 V )² / 1.17Ω
p = 136.89 / 1.17
p = 117 watts
Therefore, the battery delivered 117 watts of power to the starter motor
Wavelength = (speed) / (frequency)
Wavelength = (340 m/s) / (600 /s)
Wavelength = 0.567 meter
You could change your velocity by altering both your speed and direction.
For example, if you are running north at 10 miles per hour, and turn into a street going east, then slow down to 5 miles per hour, you would have changed your velocity.
