HOPE IT HELPS LET ME KNOW IF U NEED EXPLANATION
Answer:
The first answer is correct. All of the other options include sound, which travels by material force, and can not be transmitted in a vacuum. Infra-red, radio, and microwaves are all different frequencies of light, and can thus travel through a vacuum.
The boat’s resultant velocity with respect to North is determined as 17 m/s.
<h3>Resultant velocity of the boat</h3>
The boat’s resultant velocity with respect to North is calculated as follows;
R² = Va² + Vb²
R = √(Va² + Vb²)
R = √(15² + 8²)
R = 17 m/s
Thus, the boat’s resultant velocity with respect to North is determined as 17 m/s.
