The following equations correctly expresses the relation between vectors A⃗ , B⃗ , C⃗ , and D⃗ shown in the figure: a. A⃗ +B⃗ −C⃗ −D⃗ =0

<h3>Further explanation </h3>

Vector is an object that has both a magnitude and a direction. The direction of the vector is from its tail to its head. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction.

A scalar is specified with a single number, whereas a vector is specified using both a magnitude and a direction.

Which of the following equations correctly expresses the relation between vectors A⃗ , B⃗ , C⃗ , and D⃗ shown in the figure?

a. A⃗ +B⃗ −C⃗ −D⃗ =0
b. A⃗ +B⃗ −C⃗ +D⃗ =0
c. A⃗ +B⃗ +C⃗ +D⃗ =0
d. A⃗ −B⃗ −C⃗ +D⃗ =0

A = D and B = C, therefore

$A + B = D + C\\A + B - C - D = 0$

Which example best illustrates the transfer of energy between two waves?

Pachacha [2.7K]

Answer:

Vibrations of electric and magnetic fields.

Vibration of air particles

Vibration of the water particles.

Explanation:

We have here two groups of waves. Electromagnetic wave and mechanical waves.

For the first one, electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
For the second group, mechanical waves as a sound, for instance, energy is transferred through vibration of air particles or particles of a solid through which the sound travels. Or In water waves, energy is transferred through the vibration of the water particles.

I hope it helps you!

A particle moves along the x-axis with velocity given by v(t)=3t2+6t for time tâ¥0. If the particle at position x=2 at time t=0,

sergey [27]

Answer:

b) 6

Explanation:

Given

v(t)=3t²+6t

X(0) = 2

X(1) = ?

Knowing that

v(t)=3t²+6t = dX/dt

⇒ ∫dX = ∫(3t²+6t)dt

⇒ X - X₀ = t³ + 3t²

⇒ X(t) = X₀ + t³ + 3t²

If X(0) = 2

⇒ X(0) = X₀ + (0)³ + 3(0)² = 2

⇒ X₀ = 2

then we have

X(t) = t³ + 3t² + 2

when

t = 1

X(1) = (1)³ + 3(1)² + 2

X(1) = 6

Compare these two waves

otez555 [7]

None of the choices in the picture is correct.

The blue wave has a higher pitch than the orange one, (because its waves are shorter so there are more of them in the same length of time).

AND the blue wave is also louder than the orange one, (because the amplitude of its waves is slightly greater).

There is a 250-m-high cliff at half dome in yosemite national park in california. suppose a boulder breaks loose from the top of

lorasvet [3.4K]

Part A. For this part, we use two equations for linear motion:

First we solve for t using equation 1: y0 = 0 (initial point at top), y = 250 m, v0 = 0 (at rest)

250 = 0.5 (9.8) t^2

t = 7.143 s

Now we solve for final velocity vf using equation 2:

vf = g t

vf = 9.8 (7.143)

vf = 70 m/s

Part B. First we solve for the time it takes for the sound to reach the tourist.

t(sound) = 250 / 335 = 0.746 s

Therefore the total time would be:

t = 0.746 s + 0.300 s

t = 1.05 s

<span>Hence there is enough time for the tourist to get out before the boulder hits him.</span>
