A giant treasure chest is sitting in the sand, when two rival groups of pirates (the sharks and the squids) come upon it at the same time from opposite directions. Both groups run forward and each pirate grabs a side. On the shark’s side, they have one pirate pulling with 20N, one with 30N, one with 50N, and one with 10N. On the squid’s side, they have one pirate pulling with 10N, one with 25N, one with 30N, and one with 40N.

A marble rolls off a table from a height of 1.5 meters. Approximately how much time was the marble in the air?
O 1.1 seconds
O 0.78 seconds
O 0.55 seconds
O 0.2 seconds

Answers

Answer:

t = 0.55 s

Explanation:

Given that,

Height of the marble, h = 1.5 m

We need to find the time for which the marble is in air. Let the time is t. Using second equation of motion to find it as follows :

[tex]h=ut+\dfrac{1}{2}at^2[/tex]

Here, u = 0 and a = g

[tex]h=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2h}{g}} \\\\t=\sqrt{\dfrac{2\cdot1.5}{9.8}}\\\\t=0.55\ s[/tex]

So, the marble is in air for 0.55 s. Hence, the correct option is (c).

A ball is thrown up into the air with an initial velocity of 18 m/s. A) How high does the ball go? B) Calculate the time needed for the ball to reach its max height.

Answers

Answer:

B) t = 1.83 [s]

A) y = 16.51 [m]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f} =v_{o} -g*t[/tex]

where:

Vf = final velocity = 0

Vo = initial velocity = 18 [m/s]

g = gravity acceleration = 9.81 [m/s²]

t = time [s]

Note: the negative sign in the above equation means that the acceleration of gravity is acting in the opposite direction to the motion.

A) The maximum height is reached when the final velocity of the ball is zero.

0 = 18 - (9.81*t)

9.81*t = 18

t = 18/9.81

t = 1.83 [s], we found the answer for B.

Now using the following equation.

[tex]y = y_{o} + v_{o}*t - 0.5*g*t^{2}\\[/tex]

where:

y = elevation [m]

Yo = initial elevation = 0

y = 18*(1.83) - 0.5*9.81*(1.83)²

y = 16.51 [m]

Which temperature is the hottest? 98 F or 39 C or 303K?
F= 1.8C + 32
C= (F-32)/1.8

Answers

Answer:

The hottest temperature is  [tex]T_2 = 39^o C[/tex]

Explanation:

From the question we are given

    [tex]T_1 = 98 F[/tex]

  [tex]T_2 = 39^oC[/tex]

  [tex]T_3 = 303 \ K[/tex]

Generally converting [tex]T_3[/tex] to  Fahrenheit

    [tex]T_3' = (T_3 -273 ) * \frac{9}{5} + 32[/tex]

=> [tex]T_3' = (303 -273 ) * \frac{9}{5} + 32[/tex]

=> [tex]T_3' = 86 F[/tex]

Converting  [tex]T_2[/tex] to  Fahrenheit

      [tex]T_2' = T_2 * \frac{9}{5} + 32[/tex]

=> [tex]T_2' = 39 * \frac{9}{5} + 32[/tex]

=> [tex]T_2' =102.2 F[/tex]

Adhira loves to ride her bike around the neighborhood. She starts riding 1.2 miles at 30° S of E. Then, she rides another 2.0 miles at 20° W of S. Next, she rides 1.6 miles at 30° S of W. And finally, she rides 2.6 miles at 15° W of N. What is her final displacement from her starting point?

Answers

Answer:

D = 1.8677 miles , θ = 24.28º at South of West

Explanation:

This is an exercise in adding vectors, the easiest way to solve them is to decompose the vectors and add each component algebraically. Let's use trigonometry

first displacement. d = 1.2 miles to 30º south of East

     cos ( 360-30) = cos (-30) = x₁ / d

     sin (-30) = y₁ / d

     x₁ = d cos (-30)

     y₁ = d sin (-30)

     x₁ = 1.2 cos (-30) = 1,039 miles

     y₁ = 1.2 sin (-30) = -0.6 miles

second shift. d = 2.0 miles to 20º West of South

       cos (270-20) = x₂ / d

       cos (250) = y₂ / d

       x₂ = 2.0 cos 250 = -0.684 miles

       y₂ = 2.0 sin250 = -1.879 miles

Third displacement. d = 1.6 miles to 30º South of West

       cos (180 + 30) = x₃ / d

       sin (210) = y₃ / d

       x₃ = 1.6 cos 210 = -1.3856 miles

       y₃ = 1.6 sin 210 = -0.8 miles

Fourth displacement. d = 2.6 miles to 15º West of North

       cos (90 + 15) = x₄ / d

       sin (105) = y₄ / d

       x₄ = 2.6 cos 105 = -0.6729 miles

       y₄ = 2.6 sin 105 = 2,511 miles

having all the components we add

x-axis  (West-East direction)

       X = x₁ + x₂ + x₃ + x₄

       X = 1.039 -0.684 - 1.3846 - 0.6729

       X = -1.7025 miles

   

       Y = y₁ + y₂ + y₃ + y₄

       Y = -0.6 -1.879 -0.8 +2.511

       Y = -0.768

The modulus of this displacement is we use the Pythagorean theorem

      D = √ (X² + Y²)

      D = √ (1.7025² + 0.768²)

      D = 1.8677 miles

let's use trigonometry to find the direction

       tan θ = Y / X

       θ = tan⁻¹ Y / x

       θ = tan⁻¹ (0.768 / 1.7025)

       θ = 24.28º

as the two components are negative this angle is in the third quadrant

therefore in cardinal direction form is

         θ = 24.28º at South of West

Hey buddy, here is your answer. Hope it helps you.

Explanation:

Solids.Sound travels fastest through solids. This is because molecules in a solid are packed against each other. When a vibration begins, the molecules of a solid immediately collide and the compression wave travels rapidly.Sound moves slowest through a gas. That’s because the molecules in a gas are spaced very far apart. In order for sound to travel through air, the floating molecules of matter must vibrate and collide to form compression waves. Because the molecules of matter in a gas are spaced far apart, sound moves slowest through a gas.

Sound travels faster in liquids than in gases because molecules are packed more closely together. This means that when the water molecules begin to vibrate, they quickly begin to collide with each other forming a rapidly moving compression wave.

A person travels by car from one city to another. He drives for 30.0 min at 80.0 km/h, 12.0 min at 105 km/h, and 45.0 min at 40.0 km/h, and he spends 15.0 min eating lunch and buying gas. What is the average speed for the trip?

Answers

Answer:

53.53 km/h

Explanation:

Given that the person drives for 30.0 min at 80.0 km/h, 12.0 min at 105 km/h, and 45.0 min at 40.0 km/h, and he spends 15.0 min eating lunch and buying gas.

So, the total time to complete the journey is

t=30+12+45+15=102 min

[tex]=\frac{102}{60}=1.7[/tex] hours

As distance=(speed)x(time), so

the distance covered in 30 minutes with a speed of 80 km/h

[tex]d_1=80 \times \frac{30}{60}=40[/tex] km.

The distance covered in 12 minutes with a speed of 105 km/h

[tex]d_2=105 \times \frac{12}{60}=21 km[/tex].

The distance covered in 45 minutes with a speed of 40 km/h

[tex]d_3=40 \times \frac{45}{60}=30 km[/tex].

So, to the total distance covered is

[tex]d=d_1+d_2+d_3[/tex]

[tex]=40+21+30=91 km[/tex]

As the average speed = (Total distance covered)/(Total time taken)

So, the average speed for the whole journey

[tex]=\frac{d}{t}[/tex]

[tex]=\frac{91}{1.7}= 53.53 km/h[/tex].

Hence, the average speed for the trip is 53.53 km/h.
