a flashlight bulb with a 6.00 resistor uses 18.0W of power. What is the current through the bulb
a. I= 2.00A
b. I=3.00A
c. I=1.73A
d. I =0.333A
We need voltage first
P=V²/RV²=PRV²=18(6)V²=108V=√108V=10.4VApply oHMS law
V/I=RI=V/RI=10.4/6I=1.73AAnswer:
c. I = 1.73A
Explanation:
The formula for power :
P = VIThe formula for potential difference :
V = IRCalculating P by inputting the formula of V :
P = (IR)(I)P = I²RSolving using the given values :
18 = I² x 6I² = 3I = √3I = 1.73A1. An athlete runs 18 Kilometers in 2.5 hours, bicycles 150 Km in 4 hours, swims 10 Km in 3 hours.
Calculate:
a) the average speed for each leg of the triathlon
b) the average speed for the entire competition
The average speed is 18.73 km/hour.It is found as the ratio of the total distance and the total time taken.
What is the average speed?The total distance traveled by an object divided by the total time taken is the average speed.
The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.
The given data in the problem is;
Distance (d₁) = 18 Kilometers
Time (t₁) = 2.5 hours
Distance (d₂) = 150 Km
Time (t₂)= 4 hours
Distance (d₃) =10 Km
Time (t₃)=3 hours.
The average speed is found as;
[tex]\rm v_{avg}= \frac{Total \ distance }{Total \ time } \\\\ V_{avg}=\frac{18+150+10}{2.5+4+3} \\\\ v_{avg}= 18.73 \ km/hours[/tex]
Hence, the average speed is 18.73 km/hour.

An object is placed 15.0 cm to the left of a double-convex lens of focal length 20.0 cm. The image of this object is located.
The image of this object is located at -60 cm. The formula for the mirror equation is used in the given problem.
What is a mirror equation?A mirror equation is an equation that relates object distance and image distance to focal length.
The given data in the problem is;
Image distance (u) = 15 cm
Object distance (v) = ?
f is the mirror's focal length=20 cm
The mirror equation is given as;
[tex]\rm \frac{1}{v} +\frac{1}{u} =\frac{1}{f} \\\\ \rm \frac{1}{v} =\frac{1}{20} -\frac{1}{15} \\\\ \frac{1}{v} = 0.01666 \\\\\ v=-60 \ cm[/tex]
Hence, the image of this object is located at -60 cm.

An object with a mass of 10 kg is
dropped at the same time as an object with a mass of 100 kg. Assuming both objects are in free fall, explain how they will fall in comparison to one another.
Answer:
See below
Explanation:
They will fall at the same speed .....they will stay together if we ignore air friction
When astronomers look at stars outside of our galaxy, they have noticed that the color of the stars appears to be shifted slightly to the red end of the visible spectrum; this means that the wavelength of the light coming from those distant stars is longer than expected. If this red shift is assumed to be caused by the relative motion of the stars, what does that tell us about their movement?
They are moving toward the Earth.
They are moving away from the Earth.
They are not moving relative to the Earth.
Both the Earth and the star are stationary.
Answer:
moving away
Explanation:
They are moving AWAY from earth making the wavelengths longer than what was emitted....this is called 'Red Shift'.... longer waves is a shift toward the RED end of the spectrum .. (ROY G BIV)
