5. One of the attractions at Typhoon Lagoon, a water park in Florida, is a surf
pool. 303,200.0 liters of water are used for each wave in the surf pool and
waves are generated every 90 seconds. How many gallons of water are used
every 30 minutes in the surf pool.?
Answer:
1595790 gallons
Explanation:
Given that;
3.8 L = 1 US gallon
303,200.0 liters = 303,200.0 * 1/ 3.8 = 79789.5 gallons
If a wave is made every 90 seconds which is 1.5 mins
Then;
Number of waves made in 30 minutes = 30/1.5 = 20 waves
if each uses 79789.5 gallons, then 20 waves will use 20 * 79789.5 gallons = 1595790 gallons
To illustrate the use of a multistage rocket consider the following:
(a) A certain rocket carries 60% of its initial mass as fuel. (That is, the mass of fuel is 0.6mo) What is the rocket's final speed, accelerating from rest in free space, if it burns all its fuel in a single stage? Express your answer as a multiple of v ex .
(b) Suppose instead it burns the fuel in two stages as follows: In the first stage it burns a mass 0.3m o of fuel. It then jettisons the first-stage fuel tank, which has a mass of 0.1m o , and thenburns the remaining 0.3m 0 of fuel. Find the final speed in this case, assuming the same value of vex throughout and compare.
Answer:

[tex]v_f = 0.916 v_{ex}[/tex]
b
[tex]v_f = 1.05 v_{ex}[/tex]
Explanation:
Considering question a
From the question we are told that
The mass of the rocket is [tex]m_o[/tex]
The mass of the fuel which is in the rocket is m = 0.6 M
Generally given that the rocket burns all it fuel in a single stage , the final velocity of the rocket is mathematically represented as
[tex]v_f = v_{ex} ln [\frac{m_o}{m_k} ][/tex]
Here [tex]m_k[/tex] is the mass of the rocket without fuel which is mathematically evaluated as
[tex]m_k = m_o- m[/tex]
=> [tex]m_k = m_o -0.6m_o[/tex]
=> [tex]m_k = [1- 0.6] m_o[/tex]
=> [tex]v_f = v_{ex} ln [\frac{m_o}{[1 - 0.6]m_o} ][/tex]
=> [tex]v_f = 0.916 v_{ex}[/tex]
Considering question b
From the question we are told that
The mass of the fuel it burn at the first stage is [tex]m = 0.3 m_o[/tex]
The mass of the first stage fuel tank [tex]m_1 = 0.1 m_o[/tex]
The mass of the fuel at the second stage is [tex]m_f = 0.3m_o[/tex]
Generally the velocity of the rocket at the first stage is mathematically represented as
[tex]v_i = v_{ex} * ln [ \frac{m_o }{[1- m]m_o } ][/tex]
=> [tex]v_i = v_{ex} * ln [ \frac{m_o }{[1- 0.3]m_o } ][/tex]
=> [tex]v_i = v_{ex} * ln [ \frac{1 }{0.7 } ][/tex]
=> [tex]v_i =0.357 v_{ex}[/tex]
Generally the mass of the rocket after first stage is
[tex]m_r = m_o - 0.3m_o -0.1m_o[/tex]
=> [tex]m_r = 0.6m_o[/tex]
Generally the final velocity of the rocket at the second stage is
[tex]v_f = v_i + v_{ex} * ln [\frac{m_r}{ m_f } ][/tex]
=> [tex]v_f = v_i + v_{ex} * ln [\frac{0.6 m_o }{0.3mo } ][/tex]
=> [tex]v_f = 0.357 v_{ex} + 0.693 v_{ex}[/tex]
=> [tex]v_f = 1.05 v_{ex}[/tex]

Current 1 of 8.4 A runs for 240 seconds and then stops. Current 2 is 10.5 A. How long does current 2 have to run to deliver the same amount of charge as current 1?
This question involves the concepts of current and charge.
Current 2 has to run for "192 s" to deliver the same amount of charge as current 1.
CurrentThe current is defined as the amount of charge passing per unit time. Mathematically,
[tex]I=\frac{q}{t}\\\\q = It[/tex]
Since, the charge for both the currents is same:
q₁ = q₂
I₁t₁ = I₂t₂
[tex]t_2=\frac{I_1t_1}{I_2}[/tex]
where,
I₁ = current 1 = 8.4 A
I₂ = current 2 = 10.5 A
t₁ = time for current 1 = 240 s
t₂ = time for current 2 = ?
Therefore,
[tex]t_2=\frac{(8.4\ A)(240\ s)}{10.5\ A}[/tex]
t₂ = 192 s

In a lacrosse game a ball is thrown with a force of 2000 N. The throwing force acted for 0.8
seconds. If the ball had a change in velocity, Av, of 50 m/s, what is the mass of the ball?
Answer:
Mass, m = 32 kg
Explanation:
Given that,
Force, F = 2000 N
The change in velocity, (v-u) = 50 m/s
Time, t = 0.8 s
We need to find the mass of the ball. The net force acting on an object is given by :
F = ma
Where a is acceleration
[tex]F=\dfrac{m(v-u)}{t}\\\\m=\dfrac{Ft}{(v-u)}\\\\m=\dfrac{2000\times 0.8}{50}\\\\m=32\ kg[/tex]
So, the mass of the ball is 32 kg.

We do not use water instead of mercury in a barometer.. why.
Answer:
Required Answer:-We don't use water as Water don't expand when it came in connection of temperature.observe the figure given carefully volume of water in each vessel is shown arrange them in order of decreasing pressure at the base of each vessel explain the reason
Answer:
See the explanation below
Explanation:
The pressure is defined as the product of the density of the liquid by the gravitational acceleration by the height, and can be easily calculated by means of the following equation.
[tex]P=Ro*g*h[/tex]
where:
Ro = density of the fluid [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = elevation [m]
In this way we can understand that the greater pressure is achieved by means of the height of the liquid, that is, as long as the fluid has more height, greater pressure will be achieved at the bottom.
Therefore in order of decreasing will be
The largest pressure with the largest height of the liquid, container B. The next is obtained with container D, the next with container A and the lowest pressure with container C.
The pressure decreases as we go from the container B - D - A - C
A motorcyclist drives around a bend with a 20 m radius, with a constant velocity of 3 m/s. The motorcyclist and the motorcycle have a combined mass of 50 kg. What is the motorcyclist’s centripetal acceleration?
Answer:
[tex]a=0.45\ m/s^2[/tex]
Explanation:
Given that,
The radius of a bend, r = 20 m
Velocity of motorcyclist, v = 3 m/s
The combined mass of motorcyclist and the motorcycle is 50 kg
We need to find the motorcyclist’s centripetal acceleration. The formula used to find the centripetal acceleration is given by :
[tex]a=\dfrac{v^2}{r}\\\\a=\dfrac{(3)^2}{20}\\\\a=0.45\ m/s^2[/tex]
So, the acceleration of the motorcyclist is [tex]0.45\ m/s^2[/tex].
A stone is thrown straight up. While the stone is rising:
A. its acceleration is upward and decreasing
B. its acceleration is upward and constant
C. its acceleration is upward and increasing
D. its acceleration is zero
E. None of the above.
Answer:
D. its acceleration is zero
Explanation:
Acceleration can be defined as the rate of change of the velocity of an object with respect to time.
This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.
Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
In this scenario, a stone is thrown straight up. While the stone is rising its acceleration is zero because it's initial velocity is zero and it's until the stone reaches its highest point before the acceleration becomes constant and acting downward.
