<h2>
Velocity of the boat with respect to Earth is 5 m/s 56.31° north of east</h2>
Explanation:
A boat heads north in still water at 4.5 m/s directly across a river that is running east at 3.0 m/s.
Let north be positive y axis and east be positive x axis.
We have
Velocity of boat = 4.5 j m/s
Velocity of river = 3 i m/s
Velocity of the boat with respect to Earth = 3 i + 4.5 j
That is 56.31° north of east.
Velocity of the boat with respect to Earth is 5 m/s 56.31° north of east
Answer:
True
Explanation:
Scientists and professionals in health sciences are invited to participate in congresses, conferences and events. Communications to conferences can be of different types, but it is always necessary to draw a table with the contents that you want to present.
Due to the rise and importance of conferences in recent years, scientists and scientific societies that provoke conferences have gained greater knowledge of the importance of defining their publications, so that the problems related to these issues are becoming smaller .
It is important to know how to write the communication and if the conference proceedings or reports will be considered as primary publication, then it is recommended to prepare the manuscript in the same style as the journal articles. For this it is recommended to use the same method.
Answer:
The density is 62/17.
Explanation:
The formula for density is mass/volume, and we can calculate the volume of the toy car is 17. so if the mass of the car is 62, and the volume is 17, then we can turn this into an equation: 62/17.
