Answer: D. Energy released from atoms.
Answer: D
Rs = 10.0 m/s
The speed of the boat relative to an observer standing on the shore as it crosses the river is 10.0m/s
Explanation:
Since the boat is moving perpendicular to the current of the river, the speed of the boat has two components.
i. 8.0m/s in the direction perpendicular to the current
ii. 6.0m/s in the direction of the current.
So, the resultant speed can be derived by using the equation;
Rs = √(Rx^2 + Ry^2)
Taking
Ry = 8.0m/s
Rx = 6.0m/s
Substituting into the equation, we have;
Rs = √(6.0^2 + 8.0^2)
Rs = √(36+64) = √100
Rs = 10.0 m/s
The speed of the boat relative to an observer standing on the shore as it crosses the river is 10.0m/s
Heat transfer by means of fluid flow is called "convection".
The magnitude of the electric field inside the picture tube is 998.476 kN/C.
<h3>What is an electric field?</h3>
It is an area in the space where a charged particle experiences a force. It can be calculated by the formula,
Where,
= electric field produced
= charge = 
= distance = 
= Coulomb's constant = 
Put the values in the formula,
Therefore, the magnitude of the electric field inside the picture tube is 998.476 kN/C.
