Six automobiles are initially traveling at the indicated velocities. The automobiles have different masses and velocities. The d

rivers step on the brakes and all automobiles are brought to rest. Red Car: 1000kg, 10m/s Yellow Car: 2,000kg, 5m/s Blue Car: 500kg, 20m/s Light Blue Car: 1,000kg, 20m/s Green Car: 500kg, 10m/s Purple Car: 4,000kg, 5m/s Part A Rank these automobiles based on the magnitude of their momentum before the brakes are applied, from largest to smallest. Rank from largest to smallest. To rank items as equivalent, overlap them.

Answer:

Ranking the cars based on magnitude of momentum <em>(largest to smallest)</em>:

1. Purple, Light Blue

2. Red, Yellow, Blue

3. Green

Explanation:

Based on the given parameters ( mass and velocity), we can calculate the momentum of the various cars using the formula:

momentum = mass x velocity

1. Momentum of red car = 1000kg x 10m/s = 10,000Kgm/s

2. Momentum of Yellow car = 2000kg x 5m/s = 10,000Kgm/s

3. Momentum of blue car = 500kg x 20m/s = 10,000Kgm/s

4. Momentum of light blue car = 1000kg x 20m/s = 20,000Kgm/s

5. Momentum of green car = 500kg x 10m/s = 5,000Kgm/s

6. Momentum of purple car = 4000kg x 5m/s = 20,000Kgm/s

Hence,

Ranking the  based on magnitude of momentum <em>(largest to smallest)</em> we have:

1. Purple, Light Blue

2. Red, Yellow, Blue

3. Green

Sveta_85 [38]
<span>To answer this question, the equation that we will be using is:
 y = A cos bx + c
 where A = amplitude, b = 2 pi/Period, Period = 12 hrs, c = midline,
  x = t and y = f(t)

  A = 1/2 (Xmax - Xmin)
12 - 2 / 2 = 10/2 = 5
  b = 2 pi / 12 = pi/6
  c = 1/2 (Xmax + Xmin)
  12+2/2 = 7
  answer: f(t) = 5 cos pi/6 t + 7 </span>

A rock thrown with speed 7.50 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 18.0 m bef
Iteru [2.4K]

Answer:

height from where rock was thrown is 27.916 m

Explanation:

speed = 7.50 m/s

θ = 30°

g= 9.8 m/s²

horizontal distance = 18 m

time require for vertical displacement

time = \frac{distance}{velocity} \\t = \frac{18}{7.5\ cos30^0}

t = 2.8 sec

now for calculation of height

s = ut + 0.5 a t²

-h = v sinθ× t + 0.5 ×(-9.8)× (2.8²)

-h = 7.5 sin30°× 2.8 - 0.5 ×(9.8)× (2.8²)

-h = -27.916 m

h= 27.916 m

height from where rock was thrown is 27.916 m

A proton is accelerated from rest through a potential difference V0 and gains a speed v0. If it were accelerated instead through
Svet_ta [14]

Answer:

The speed is \sqrt{2}v_{0}.

(a) is correct option.

Explanation:

Given that,

Potential difference V= V_{0}

Speed v = v_{o}

If it were accelerated instead

Potential difference V'=2V_{0}

We need to calculate the speed

Using formula of initial work done on proton

W = q V

We know that,

\Delta W=\Delta K.E

q V=\dfrac{1}{2}mv^2

Put the value into the formula

q V_{0}=\dfrac{1}{2}mv_{0}^2

v_{0}^2=\dfrac{2qV_{0}}{m}....(I)

If it were accelerated instead through a potential difference of 2 V_{0}, then it would gain a speed will be given as :

Using an above formula,

v_{0}'^2=\dfrac{2qV_{0}}{m}

Put the value of V_{0}

v_{0}'^2=\dfrac{2q\times2V_{0}}{m}

v_{0}'=\sqrt{\dfrac{4qV_{0}}{m}}

v_{0}'=\sqrt{2}v_{0}

Hence, The speed is \sqrt{2}v_{0}.

what is the ratio of ey,final, the maximum value of the y-component of the electric field immediately following the last polariz
OleMash [197]

That ratio is 2 .

<h3>What is ratio?</h3>

A ratio is the  comparison of the  two numbers bydivision.

Taking the first two outputs, or the  -1/8 and -1/4, we can divide not the second one by the first one to find the

ratio:

-1/4-1/8

When dividing fractions, we multiply by the reciprocal:

-1/4x-8/1

To multiply fractions, multiply straight across:

(-1x-8)/(4x1) 8/4=2
