Answer:

141.152 miles per hour  is the speed of the plane in miles per hour

Explanation:

Speed of plane = Total distance travelled/total time taken -

v = D/t

Substituting the given values in the above equation, we get

v = 467/3.3 miles /hour

v = 141.152 miles per hour

141.152 miles per hour  is the speed of the plane in miles per hour

What is the relationship between the speed of an object and its kinetic energy?
VladimirAG [237]

Answer:

For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four.

Which if, any, of these statements are true? (More than one may be true.) Assume the batteries are ideal. Check all that apply.
Maurinko [17]

Answer:

All are true except the last point that says that a battery is a current source and the current at the outlet is always the same.

Explanation:

  • A battery is an electro-chemical device which converts the chemical energy into usable electrical energy thus it provides electrical energy.
  • Since, the battery maintains a a constant potential difference between its terminals, once connected.
  • Since, the movement of electric current requires energy, which is supplied by the electric potential energy stored in the battery.
  • The current in the battery flows as per the Ohm's law and we can not say that the current leaving will always remain constant.
  • As the current is the flow of electric charge, and charges are not stored in batteries unlike capacitors, thus the current at the leaving end will depend on Ohm's law and will vary accordingly.

Make the curvature radius 0.6 m, the refractive index 1.5, and the diameter 0.6 m. place the lamp so that the source of light is
vodka [1.7K]
We are given
r = 0.6 m
n = 1.5
D = 0.6 m, R1 = 30 cm
R2 = 120 cm

We are asked to get the focal length and the distance of the focal plane from the lens

We use the formula
1 / f = ( n - 1) (1/R1 - 1/R2)
Substituting and solving for f
1/ f = (1.5 - 1) (1/30 - 1/120)
f = 80 cm

The focal length is 80 cm and the distance of the focal plane from the lesn is 80 cm - 30 cm = 50 cm.<span />

an air craft is travelling due north with velocity of 100m/s astrong wind blow from the west with in velocity of 25m/s the reshs
OleMash [197]

Explanation:

The aircraft is traveling north at 100 m/s.

The wind blows from the west (towards the east) at 25 m/s.

The two vectors form a right triangle.  The magnitude of the resultant velocity can be found with Pythagorean theorem:

v² = vx² + vy²

v² = (25 m/s)² + (100 m/s)²

v = 103 m/s

The direction can be found with trigonometry:

θ = atan(vy / vx)

θ = atan(100 / 25)

θ = 76.0°

The resultant velocity is 103 m/s at 76.0° north of east.
