Acannon shoots an artillery shell with a initial velocity of 400 meters/second at an indirect fire angle of 60 on level ground where does it land if friction effects are neglected

14139.19 m

Explanation:

This situation is related to parabolic motion and can be solved using the following equations:

(1)

(2)

Where:

is the horizontal distance (where the artillery shell lands)

is the initial velocity

is the angle

is the time

is the final height

is the initial height

is the acceleration due gravity, always directed downwards

So, let's begin by isolating from (2):

(3)

(4)

Substituting (4) in (1):

(5)

Rewriting (5) and taking into account :

(6)

(7)

Finally:

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

explanation:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
