Answer:
when sun shines through rain
Explanation:
Rainbow is an arc of different colours that appears in the sky when sun shines through rain
Answer:
assertion is true but the reason is not true
Explanation:
Answer: For the angles below 40, The air time and range are directly proportional meaning that if air time increases, the range increases. Like said earlier, the total traveled distance in the x-direction depends on the initial velocity and time.
Answer:
30
Explanation:
well I got it right but I'm not sure if it's the same thing
Answer:
Explanation:
Given that,
A portable music player is operating with 4 cell batteries connected in series, and each cell has a P.D of 1.5V.
Then,
Total potential difference is
P.D_total = V1 + V2 + V3 + V4
P.D_total = 1.5 + 1.5 + 1.5 + 1.4
P.D_total = 6V.
The music player provides a resistance of 15,000Ω
R = 15,000Ω
We want to find the current (I) flowing through the music player?
Using ohms law
V = IR
Where
V is the potential difference
I is the current
R is the resistance
Therefore,
I = V/R
I = 6 / 15,000
I = 4 × 10^-4 A
I = 0.4 × 10^-3 A
I = 0.4 mA.
So, 0.4mA is passing through the music player
