Explanation:
The difference in frequency can be calculated using the formula
f= source frequency from the ship
v'= speed of the wave reflected from the whale = 4.95 m/s
v= speed of the ship.
since, the source frequency and speed of the ship data is missing, calculation of difference in frequency not possible.
Answer: 0.55m
1. First find Vf
• 4 Sin(10)=0.7
•Vf= 0.7
2. Find time
•9.8=0.7/t
•9.8t=0.7
•t=0.07
3. Find distance
• 4 Cos(10)=d/0.14 < ————- double time
• d=0.55m
Glass is the material that would provide the most electrical resistance.
Elements which are good conductors of electricity are referred to as
Metals. They usually have low resistance.
<h3> Examples of Metals</h3>
Non metals are are low conductors of electricity and have high resistance.
Electrolytes such as salt water are also good conductors of electricity.
Glass are generally regarded as Insulators and are poor conductors of
electricity which makes it the material with the most electrical resistance.
