Answer:

the bearing of the angle AC will be equal to 154°51' 48"

Explanation:

given,

bearing of  line AB = 234° 51' 48"

C is  anti clockwise angle from 80° from AB      

bearing of line AC = ?                  

To calculate the bearing of line AB  80° anticlockwise movement

bearing of the AC =  234° 51' 48"  - 80°                

                              = 154°51' 48"                

The bearing can be represented as 154.5148

hence, the bearing of the angle AC will be equal to 154°51' 48"

A 24 volt battery is connected to a 3Ω resistor and a 5Ω resistor in series. What is the current in the circuit?
Vladimir [108]

Answer: 3 Amperes

Explanation:

Voltage of battery = 24 volts

R1 = 3Ω

R2 = 5Ω

Total resistance = ?

Current, I = ?

Since the resistors are connected in series, the total resistance (Rtotal) of the circuit is the sum of each resistance.

i.e Rtotal = R1 + R2

Rtotal = 3Ω + 5Ω = 8Ω

Now recall that voltage = current x resistance

i.e V = I x Rtotal

24volts = I x 8Ω

I = 24 volts / 8Ω

I = 3 amperes

Thus, there is 3 Amperes of current in the circuit

Three forces act on an object. Two of the forces are at an angle of to each other and have magnitudes N and N. The third is perp
grin007 [14]

Explanation:

Assuming that all forces extend from the origin point, with F_1 and F_2 lying in the xy plane, so F_3 is along the z axis. So, we have:

\vec{F_1}=F_1\hat{i}+0\hat{j}+0\hat{k}\\\vec{F_2}=F_2cos\theta\hat{i}+F_2sin\theta\hat{j}+0\hat{k}\\\vec{F_3}=0\hat{i}+0\hat{j}+F_3\hat{k}

The net force is:

\vec{F}=\vec{F_1}+\vec{F_2}+\vec{F_3}\\\vec{F}=(F_1+F_2cos\theta)\hat{i}+F_2sin\theta\hat{j}+F_3\hat{k}

The force (F_4) that would exactly counterbalance these three forces will be opposite in direction and equal in magnitude to the net force:

\vec{F_4}=-(F_1+F_2cos\theta)\hat{i}-F_2sin\theta\hat{j}-F_3\hat{k}\\F_4=\sqrt{(-(F_1+F_2cos\theta))^2+(-F_2sin\theta)^2+(-F_3)^2}

Neporo4naja [7]

Answer:

A.) 355 m/s

B.) 0.71 m

C.) 500Hz

Explanation:

Given that a police car is traveling due east at a speed of 15.0 m/s relative to the earth. You are in a convertible following behind the police car. Your car is also moving due east at 15.0 m/s relative to the earth, so the speed of the police car relative to you is zero. The siren of the police car is emitting sound of frequency 500 Hz. The speed of sound in the still air is 340 m/s

a.) What is the speed of the sound waves relative to you?

Since the car is moving away from the observer, the relative velocity will be:

Relative velocity = 340 + 15

Relative velocity = 355 m/s

b.) What is the wavelength of the sound waves at your location?

Using the wave speed formula

V = frequency × wavelength

Make wavelength the subject of formula.

Wavelength = Velocity / frequency

Wavelength = 355/500

Wavelength = 0.71 m

c.) What frequency do you detect?

Fo = Fs ( C + V ) / ( C + v )

Fo = Fs

That is, the frequency of the observer will be equal to the frequency of the source.

Therefore, Fo = 500Hz
