The pressure experienced by the wheel of the tricycle is 1.85×10¹⁰ N/m²

<h3>What is pressure?</h3>

Pressure can be defined as the force acting perpendicular per unit area on the surface of a body. The S.I unit of pressure is N/m²

To calculate the pressure of the wheel of the tricycle, we use the formula below

Formula:

  • P = 4mg/πd².............. Equation 1

Where:

  • P = Pressure of the tricycle wheel
  • m = mass of the wheel
  • d = diameter of the wheel
  • g = acceleration due to gravity
  • π = pie.

From the question,

Given:

  • m = 150 kg
  • d = 0.001 m
  • g = 9.8 m/s²
  • π = 3.14

Substitute these values into equation 1

  • P = 4(150)(9.8)/(0.001²×3.14)
  • P = 5880/0.00000314
  • P = 1.85×10¹⁰ N/m²

Hence, The pressure experienced by the wheel of the tricycle is 1.85×10¹⁰ N/m².

An amusement park ride consists of a rotating circular platform 11.1 m in diameter from which 10 kg seats are suspended at the e
frozen [14]

To solve this problem we will use the relationship given between the centripetal Force and the Force caused by the weight, with respect to the horizontal and vertical components of the total tension given.

The tension in the vertical plane will be equivalent to the centripetal force therefore

Tsin\theta= \frac{mv^2}{r}

Here,

m = mass

v = Velocity

r = Radius

The tension in the horizontal plane will be subject to the action of the weight, therefore

Tcos\theta = mg

Matching both expressions with respect to the tension we will have to

T = \frac{\frac{mv^2}{r}}{sin\theta}

T = \frac{mg}{cos\theta}

Then we have that,

\frac{\frac{mv^2}{r}}{sin\theta} =  \frac{mg}{cos\theta}

\frac{mv^2}{r} = mg tan\theta

Rearranging to find the velocity we have that

v = \sqrt{grTan\theta}

The value of the angle is 14.5°, the acceleration  (g) is 9.8m/s^2 and the radius is

r = \frac{\text{diameter of rotational circular platform}}{2} + \text{length of chains}

r = \frac{11.1}{2}+2.41

r = 7.96m

Replacing we have that

v = \sqrt{(9.8)(7.96)tan(14.5\°)}

v = 4.492m/s

Therefore the speed of each seat is 4.492m/s

denis-greek [22]

Answer:

1050 possible selections

Explanation:

<em>Number of red balls = 7</em>

<em>Number of blue balls = 10</em>

<em>Let blue balls be B and red balls be R</em>

<em>four balls are to be selected. At least three must be blue.</em>

the first combination is 4blue 0red

second combination is 3blue 1red

(10C4*7C0 + 10C3*7C1)

210 *1 +120 *7

210+840

An inclined plane is 30 meters long and 2 meters high what is the mechanical advantage of the inclined plane
Vladimir79 [104]

Answer:MA = 15

Explanation:The mechanical advantage for an inclined plane is MA=l/h or length divided by height. So, plugging these variables into the equation would have it set up like this: MA = 30/2. When 30 is divided by 2 you get your answer for mechanical advantage, which would be 15

If a ski lift raises 150 passengers averaging 590 N in weight to a height of 244 m in 96.3 s, at constant speed, what average po
SVEN [57.7K]

Answer:

224236.76 W

Explanation:

Power: This can be defined as the rate of change of energy. The S.I unit of power is Watt(W).

From the question,

P = E/t ......................... Equation 1

Where P = power, E = Energy or work, t = time.

But,

E = Wt×d.................. Equation 2

Where Wt = Total weight of the passengers, d = distance.

Substitute equation 2 into equation 1

P = (Wt×d)/t.............. Equation 3

Given: Wt = 590×150 =88500 N, d = 244 m, t = 96.3 s.

Substitute into equation 3

P = (88500×244)/96.3

P = 224236.76 W
