N2 + 2O2 → 2NO2
The number to be placed before O2 is 2
Answer:
The balanced condition for Wheatstones bridge is
Q
P
=
S
R
as is obvious from the given values.
No, current flows through galvanometer is zero.
Now, P and R are in series, so
Resistance,R
1
=P+R
=10+15=25Ω
Similarly, Q and S are in series, so
Resistance R
2
=R+S
=20+30=50Ω
Net resistance of the network as R
1
and R
2
are in parallel
i=

Answer:
The number of turns present in the loop are 625 turns.
Explanation:
Given;
current on the rectangular loop, I = 6A
Dimension of the rectangular loop, L x B = 0.04 m × 0.08 m
Magnetic moment of the loop, Pm = 12 Am²
Area of the rectangular loop, A = L x B = 0.04 m × 0.08 m = 0.0032 m²
The magnetic moment of plane carrying coil/loop is given as;
Pm = NIA
Where;
N is the number of turns
A is the area of the loop
I is the current on the loop
Therefore, the number of turns present in the loop are 625 turns.
Hi there!
Since the ball is directed 60° above the horizontal, we must use its HORIZONTAL component to find its displacement.
We can take the cosine to do so:
vcosθ = 28.3cos(60) = 14.15 m/s
Since the ball is in the air for 5 sec, we can use the following equation:
displacement = velocity · time (d = vt)
Plug in the values:
d = 14.15 · 5 = 70.75 m
Lumbar nerves transmit signals that allow us to walk. They are a pivotal part of the human body, and without them we would be immobile. Hope this helps.
