Answer:
120 miles/hour
Explanation:
The average speed is the ratio of total distance covered by an object or a body to the total time taken to cover the distance.
Mathematically,
<em>Average speed = total distance covered/total time taken</em>
In the case of Connie:
total distance = 180 + 180 = 360 miles
In order to calculate the time for each trip
<em>speed = distance/time</em>
<em> time = distance/speed</em>
From Phoenix to flagstaff:
time = 180/180 = 1 hour
From flagstaff back to Phoenix:
time = 180/90 = 2 hours
total time taken = 1 + 2 = 3 hours
Average speed = 360/3 = 120 miles/hour
<em>Hence, the average speed is </em><em>120 miles per hour.</em>
Sorry, I most likely did this wrong; but hopefully I didn't!

Answer:
If the particle is an electron
If the particle is a proton,
Explanation:
Initial speed at the origin,
to +ve x-axis
The particle crosses the x-axis at , x = 1.5 cm = 0.015 m
The particle can either be an electron or a proton:
Mass of an electron,
Mass of a proton,
The electric field intensity along the positive y axis , can be given by the formula:
If the particle is an electron:
If the particle is a proton:
Answer:
The angular displacement of the blade is 576,871.2 radians
Explanation:
Given;
angular speed of the Helicopters rotor blades, ω = 510 rpm (revolution per minute)
time of motion, t = 3 hours
The angular speed of the Helicopters rotor blades in radian per second is given as;
The angular displacement in radian is given as;
θ = ωt
where;
t is time in seconds
θ = (53.414)(3 x 60 x 60)\\
θ = 576,871.2 radians
Therefore, the angular displacement of the blade is 576,871.2 radians
Answer:
The principle of superposition which is also called superposition property,states that when two or more waves of the same type cross at some point, the resultant displacement at that point is equal to the sum of the displacements due to each individual wave.
