She say give tow points and write the equation of the line with the two give points (1,5) and (-3,-5 )
Answer:
Explanation:
Total resistance of 2 bulb in series
= 100 +100 = 200 ohm
current in each bulb
= 9/200 = .045 A
In case of parallel combination of bulb
total resistance
= 100 x 100 / (100+100)
50 ohm
current in the main circuit
= 9 / 50 A
current in each bulb
= 9 / (2 x 50)
.09
So in the second case current is more , hence heat generated too will be more . So brightness too will be more.
First set ( in series ) will be dimmer.
Answer:
C. Resist change in motion.
Explanation:
Inertia: the tendency of an object to resist a change in motion unless an outside force acts on the object.
The distance of the sound from the tuba is 4.82 m.
<h3>
Area of the tube</h3>
The area of the tuba is calculated as follows;
I = P/A
where;
- I is intensity of sound
- P is power
- A is area
A = P/I
A = 0.35 / (1.2 x 10⁻³)
A = 291.67 m²
<h3>Distance of the sound</h3>
Area = 4πr²
Thus, the distance of the sound from the tuba is 4.82 m.
