Answer:
The boat's velocity relative to Earth is 3.91 m/s.
Explanation:
Given;
speed of ferry due north, = 2.5 m/s
speed of the river to the east, = 3.0 m/s
The boat's velocity relative to Earth is given by;
Therefore, the boat's velocity relative to Earth is 3.91 m/s.
Answer:
deflected toward bottom of the screen
Explanation:
When entering the region with magnetic field, a magnetic force is exerted on the proton. This force is perpendicular to both the direction of the magnetic field and the direction of the velocity of the proton.
The direction of the force can be determined by using the right-hand rule. We have:
- Index finger: direction of the velocity of the proton --> to the right
- Middle finger: direction of the magnetic field --> into the screen
- Thumb: direction of the magnetic force --> toward bottom of the screen
So, the correct answer is
deflected toward bottom of the screen
Answer:
The value is
Explanation:
From the question we are told that
The amount of force a square meter of an aircraft wing should produce is
The air speed relative to the bottom of the wing is
The air level density of air is
Gnerally this force per square meter of an aircraft wing is mathematically represented as
Here u is the speed air need to go over the top surface to create the ideal lift
A is the area of a square meter i.e
So
=>
