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?

Answers

Current 1: 8.4 * 240 = 2,016 A delivered.

Current 2: 10.5 * t = 2,016
Divide each side by 10.5
t = 192

Current 2 needs to run 192 seconds 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.

Current

The 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

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?

Answers

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].

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.?

Answers

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.

Answers

Answer:

a

 [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]

What is one of the principles of charges in a conductor?

Answers

Answer:

A conductor allows free charges to move about within it. The electrical forces around a conductor will cause free charges to move around inside the conductor until static equilibrium is reached. Any excess charge will collect along the surface of a conductor. Conductors with sharp corners or points will collect more charge at those points.

Explanation:

Which of the following statement(s) about electrical charges are correct?
A. Point charges of the same charge only attract.
B. Charged and neutral extended objects can attract.
C. Charged and neutral extended objects do not interact.
D. Point charges of the same charge only repel.
E. Extended objects of opposite charge can only attract.
F. Point charges of opposite charge only attract.
G. Point charges of opposite charge only repel.
H. Extended objects of the same charge can both repel and attract.
I. Extended objects of the same charge can only attract.
J. Extended objects of the same charge can only repel.
K. Extended objects of opposite charge can both repel and attract.

Answers

Answer:

The true statements are;

F, D, E, J

Explanation:

F and D are true because they agree with our knowledge of electrostatic interaction. Like charges repel while unlike charges attract. Statements B and C are not in line with the principles of electrostatics because neutral objects do not interact with charged bodies in an electric field.

E and J are true for the same reasons outlined above. Remember that like charges always repel each other and unlike charges always attract each other.

Explanation:

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​

Answers

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

b) This includes solids with a compositions that can be identified but not expressed by an exact chemical formula; an example is glass must be inorganic.
c) This excludes the vast number of organic compounds produced by living matter. must be naturally formed or formed from naturally occuring compounds.
d) This includes the vast numbers of substances that can be produced in a laboratory but are not found in nature. must be a solid or a liquid.
e) This excludes all gases.

Answers

Answer:

The correct options are A, B, C and E

Explanation:

The above speaks to the characteristics of Minerals.

Option D is excluded because minerals cannot be liquid or gaseous. Even if it is possible, those replicated in the laboratory are not considered as minerals neither are minerals liquid. They must be solid. The molecules for most minerals are very tightly or densely arranged because of the nature of their formation. Most of them are formed under consistent and intense pressure.
