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.
