Answer:
2.5 Hz
Explanation:
3.0m/s / 1.2 m=2.5 1/s=2/5 Hz
The plane's heading is 4.61 degrees south of east, which is the direction the pilot needs to steer the plane in order to reach her objective and the trip takes 1.83 hours.
<h3>What is the distance?</h3><h3 />
Distance is a numerical representation of the distance between two objects or locations.
The distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Let the pilot's heading be theta south with an east direction. The resultant the velocity will be;
Hence the direction of the plane heading is 4.61 degrees south of east
b)
The resultant speed of the plane(V)is found as;
Hence, the trip takes 1.83 hours.

All the components (D) ie, wire, switch and resistor are needed for current to flow in a series or parallel circuit.
In a simple series circuit, all the components are connected end-to-end to form a single path for the electrons or electric current to flow through the circuit. A simple parallel circuit is where all the components in the circuit are connected between the same two sets of common points, creating a more than one path for the electrons or electric current to flow around the circuit.
It is how forces affect nature
Answer:
(a) 50 kJ
(b) 14.14 m/s
(c) 0 N
(d) 0 J
Solution:
As per the question:
Mass of car, m = 500 kg
Force, F = 1000 N
Distance traveled, s = 50 m
Now,
(a) The total work done can be given as:
(b) To calculate the speed of the car:
Using work-energy relation, we can say that the work done equals the change in the kinetic energy of the car:
where
v' = final velocity
v = initial velocity = 0
Now,
(c) To calculate the net force on the car when the velocity is constant:
The net force is given as the product of mass and acceleration:
F = ma
<em>Acceleration can be defined as the rate with which the velocity of the car changes and the since the velocity is constant, the car will not have any acceleration, a = 0</em>
Thus the net force is also zero.
(d) The total work done when the car moves with constant velocity:
