A point charge is offered to identify the electrical field approximately a charged particle. Why is it essential that the suggest charge does

It"s essential that the allude charge go not affect the position of the charge being experiment because: C) electric fields room inversely proportional come the square the the distance, so any change in position transforms the field.



A soccer kicker can give the ball an initial speed of 30 m/s. That is 45 m native the goalpost which has actually a crossbar 2.90 m high. W

∅=10.7°

Explanation:

In parabolic movement the place on the x-axis deserve to be found like this.

You are watching: Leaking black fluid indicates that you should check your:

*

Where us clear the time.

*

The place on the y-axis can be uncovered as well.

*

replacing time.

*

*

*

Now we usage the quadratic equation to uncover the tangent of the angle.

*

Finally we use the arc tangent duty to discover the angle.

*

We choose the second angle because it it is adapted to the instance described, that is the minimum angle.



A rocket increases straight increase from the ground at 12.6 m/s^2 for 11.0 s. Then the engine cuts off and also the rocket enters complimentary f

hunterriverpei.com:

a) 138.6 m/s

b) 762.3 m

c) 122.3 m/s

d) 24.47

Explanation:

t = Time taken

u = initial velocity

v = final velocity

s = Displacement

a = Acceleration

*

Velocity at the finish of its increase acceleration is 138.6 m/s

*

Maximum elevation the rocket will is 762.3 m

*

The velocity v which the rocket crashes to the planet is 122.3 m/s

*

Total time indigenous launch to crash is 12.47+11 = 24.47 seconds



Any adjust in the cross section of the vocal street shifts the individual formant frequencies, the direction that the change dependi

hunterriverpei.com:

The correct hunterriverpei.com is option D.

Explanation:

It is stated in the concern that constriction of the vocal tract in ~ a place where the standing wave of a formant exhibits minimum-amplitude push oscillations generally reasons the formant to drop in frequency so to increase formant frequency, the vocal should broaden where the standing wave of a formant exhibits minimum-amplitude push oscillations. The hunterriverpei.com is D.
