Answer:

Option A. 57.14 Ω

Explanation:

From the question given above, the following data were obtained:

Resistor 1 (R₁) = 100 Ω

Resistor 2 (R₂) = 400 Ω

Resistor 3 (R₃) = 200 Ω

Equivalent Resistor (Rₚ) =?

The equivalent resistor in the above circuit can be obtained as follow:

1/Rₚ = 1/R₁ + 1/R₂ + 1/R₃

1/Rₚ = 1/100 + 1/400 + 1/200

Find the least common multiple (lcm) of 100, 400 and 200. The result is 400. Divide 400 by 100, 200 and 400 respectively and multiply the result with the numerator as shown

1/Rₚ = (4 + 1 + 2)/400

1/Rₚ = 7/400

Invert

Rₚ = 400/7

Rₚ = 57.14 Ω

Answer:

Acceleration = 0.0282 m/s^2

Distance = 13.98 * 10^12 m

Explanation:

we will apply the energy theorem

work done = ΔK.E ( change in Kinetic energy )  ---- ( 1 )

where :

work done = p * t

                  = 15 * 10^6 watts * ( 1 year ) = 473040000 * 10^6 J

( note : convert 1 year to seconds )

and ΔK.E = 1/2 mVf^2   given ; m = 1200 kg  and initial V = 0

back to equation 1

473040000 * 10^6  = 1/2 mv^2

Vf^2 = 2(473040000 * 10^6 ) / 1200

∴ Vf = 887918.92 m/s

i) Determine how fast the rocket is ( acceleration of the rocket )

a = Vf / t

  = 887918.92 / ( 1 year )

  = 0.0282 m/s^2

ii) determine distance travelled by rocket

Vf^2 - Vi^2 = 2as

Vi = 0

hence ; Vf^2 = 2as

s ( distance ) =  Vf^2 / ( 2a )

                     = ( 887918.92 )^2 / ( 2 * 0.0282 )

                    = 13.98 * 10^12 m

Answer:

The boiling point temperature of this substance when its pressure is 60 psia is  480.275 R

Explanation:

Given the data in the question;

Using the Clapeyron equation

[tex](\frac{dP}{dT} )_{sat } = \frac{h_{fg}}{Tv_{fg}}[/tex]

[tex](\frac{dP}{dT} )_{sat } = \frac{\frac{H_{fg}}{m} }{T\frac{V_{fg}}{m} }[/tex]

where [tex]h_{fg[/tex] is the change in enthalpy of saturated vapor to saturated liquid ( 250 Btu

T is the temperature ( 15 + 460 )R

m is the mass of water ( 0.5 Ibm )

[tex]V_{fg[/tex] is specific volume ( 1.5 ft³ )

we substitute

[tex](\frac{dP}{dT} )_{sat } =( \frac{250Btu\frac{778Ibf-ft}{Btu} }{0.5})[/tex] / [tex]( (15+460)\frac{1.5}{0.5})[/tex]  

[tex](\frac{dP}{dT} )_{sat } =[/tex] 272.98 Ibf-ft²/R

Now,

[tex](\frac{dP}{dT} )_{sat } =[/tex] [tex](\frac{P_2 - P_1}{T_2 - T_1})_{sat[/tex]

where P₁ is the initial pressure ( 50 psia )

P₂ is the final pressure ( 60 psia )

T₁ is the initial temperature ( 15 + 460 )R

T₂ is the final temperature = ?

we substitute;

[tex]T_2[/tex] [tex]= ( 15 + 460 ) + \frac{(60-50)psia(\frac{144in^2}{ft^2}) }{272.98}[/tex]

[tex]T_2 = 475 + 5.2751\\[/tex]

[tex]T_2 =[/tex] 480.275 R

Therefore, boiling point temperature of this substance when its pressure is 60 psia is  480.275 R

Answer:

The speed of the knife after passing through the target is 9.33 m/s.

Explanation:

We can find the speed of the knife after the impact by conservation of linear momentum:

[tex] p_{i} = p_{f} [/tex]

[tex] m_{k}v_{i_{k}} + m_{t}v_{i_{t}} = m_{k}v_{f_{k}} + m_{t}v_{f_{t}} [/tex]

Where:

[tex] m_{k}[/tex]: is the mass of the knife = 22.5 g = 0.0225 kg

[tex] m_{t}[/tex]: is the mass of the target = 300 g = 0.300 kg

[tex] v_{i_{k}}[/tex]: is the initial speed of the knife = 40.0 m/s

[tex] v_{i_{t}} [/tex]: is the initial speed of the target = 2.30 m/s

[tex]v_{f_{k}}[/tex]: is the final speed of the knife =?

[tex] v_{f_{t}} [/tex]: is the final speed of the target = 0 (it is stopped)

Taking as a positive direction the direction of the knife movement, we have:

[tex] m_{k}v_{i_{k}} - m_{t}v_{i_{t}} = m_{k}v_{f_{k}} [/tex]  

[tex] v_{f_{k}} = \frac{m_{k}v_{i_{k}} - m_{t}v_{i_{t}}}{m_{k}} = \frac{0.0225 kg*40.0 m/s - 0.300 kg*2.30 m/s}{0.0225 kg} = 9.33 m/s [/tex]

Therefore, the speed of the knife after passing through the target is 9.33 m/s.

I hope it helps you!

Answer:

his type of shock is called inelastic

Explanation:

This exercise is for vehicle crashes, which corresponds to exercise is momentum conservation.

We must begin by defining a system formed by the two cars so that the forces during the crash have been intense and the moment is preserved.

Looking for the moments

initial. Before the crash

           p₀ = m₁ v₁₀

final. After the crash

           p_f = (m₁ + m₂) v

the conservation of the moment is written

           p₀ = p_f

           m₁ v₁₀ = (m₁ + m₂) v

This type of shock is called inelastic and has the characteristics that the kinetic energy is not conserved.

Answer:

B. objects remain in the same state of motion unless a force acts on them

Explanation:

Sana nakatulong

Answer: B) objects remain in the same state of motion unless a force acts on them

Explanation:

Newton's Second Law states that The resultant force acting on an object is proportional to the rate of change of momentum.

The net force on a body = mass of object × acceleration of the object

The first option "Objects remain in the same state of motion unless a force acts on them" is an implication of the first law of motion .

The second option "For every action force there is an equal and opposite reaction force" is an implication of the third law of motion.

The last option from the given list "Net force is equal to mass times acceleration" is an implication of the second law of motion.

Answer:

a) the x-component of the net momentum is 44200 kgm/s [tex](-x)[/tex]

b) the y-component of the net momentum is 31200 kgm/s [tex](y)[/tex]

c) the magnitude of the net momentum is 54102.5 kgm/s

Explanation:

Given the data in the question;

a) x-component of the net momentum of this system.

the second vehicle ( sedan ) doesn't have momentum along x-axis, the momentum along x-axis is strictly contributed by the pick up

so;

Px = 2600 kg × 17.0 m/s [tex](-x)[/tex]

Px = 44200 kgm/s [tex](-x)[/tex]

Therefore, the x-component of the net momentum is 44200 kgm/s [tex](-x)[/tex]

b) y-component of the net momentum of this system

Also, momentum along y-axis is entirely provided by the sedan

Py = 1300 kg × 24.0 m/s [tex](y)[/tex]

Py = 31200 kgm/s [tex](y)[/tex]

Therefore, the y-component of the net momentum is 31200 kgm/s [tex](y)[/tex]

c) magnitude of the net momentum?

magnitude of the net momentum P = √( Px² + Py² )

so we substitute  

P = √( (44200)² + (31200)² )

P = √( 2927080000 )

P = 54102.5 kgm/s

Therefore, the magnitude of the net momentum is 54102.5 kgm/s

Answer:962 hz

Explanation: got it right on acellus

The frequency of the siren when the cyclist is stationary will be 963 Hz.

The frequency of a wave is the number of cycles per second.

FRom the doppler effect,

f =f'[ (V+Vs/V-Vo) ]

Here, doppler shifted frequency f' = 894 Hz, Source is stationary, Vs =0. Velocity of observer Vo = 24.5m/s and velocity of sound wave V = 343m/s

Substitute the value into the expression , we get

f = 894 x [(343/343 - 24.5)}

f = 963 Hz

Thus, the frequency of the siren when the cyclist is stationary is 963 Hz.

2 possible answers:

1# 2.5 Ω (when the resistors are in parallel)

2# 10 Ω (when the resistors are in series)

Explanation:

there are two possible answers for this:

1# if the resistors are in parallel in the circuit

then:

1/R-equivalent=1/5+1/5

1/R-equivalent=2/5

R-equivalent=5/2=2.5 Ω

2# if the resistors are in series in the circuit

then:

R-equivalent=5+5

R-equivalent=10 Ω

Two resistors, 5.0 ohm's each can be combined to give an equivalent resistance of​

If connected in series :

R = R1 + R2

R = 5 + 5

R = 10 ohms

If connected in parallel :

R = 1/R1 + 1/R2

R = 1/ 5 + 1/5

Explanation: Given that an elevator moving down passes its neighbor, an elevator moving up. Their speed relative to one another is 8 m/s. What is the velocity of each elevator relative to someone standing on the first floor? Assume that the elevators are traveling at the same speed, and that the upward direction is positive.

O Both elevators are moving at 8 m/s.

y Falling Objects

O One elevator is moving at 4 m/s; the other elevator is moving at -4 m/s.

O Both elevators are moving at 4 m/s.

tive Velocity

O One elevator is moving at 8 m/s; the other elevator is moving at -8 m/s.

Solution.

Since the upward direction is positive, the downward direction will be negative.

For their speed relative to one another to be 8 m/s, the individual velocity will be:

4 - ( - 4 ) = 8

Therefore, the correct answer is:

One elevator is moving at 4 m/s; the other elevator is moving at -4 m/s

Which is option B

Because the negative sign multiply by negative sign will give positive.
