The net force acting on the center O is 4.495 X 10⁹ N
<u>Explanation:</u>
Given:
Charge-
q₁ = 4C
q₂ = 3C
q₃ = -5C
q₄ = 2C
q₅ = 1C
Side of the square = 4cm
Net force acting on the center, F = ?
Length of the side of the square is 4cm
The length of the diagonal will be 4√2
The length of half diagonal = 4√2 / 2 = 2√2
Force acting on the center of the square is:
Here, k is coulomb's constant and the value is
k = 8.99 x 10⁹ N m2 / C2
On substituting the value, we get:
Therefore, the net force acting on the center O is 4.495 X 10⁹ N
Answer:
interference is between destructive and constructive
Explanation:
The interference of two sound waves periodicity in phase by the speakers is
Δr =
in this case they indicate that the frequency is f = 700 Hz, the wave speed is
v =λ f
λ = v / f
λ = 341/700
λ = 0.487 m
Let's use the Pythagorean theorem to find the distance that each wave travels
r₁ =
let's measure the distance from speaker 1
r₁ =
r₁ = 5,099 m
the distance from the second speaker
r₂ = \sqrt{x^2 + y^2}
r₂ =
r₂= 5.831 m
the difference in the way is
Δr = r₂ -r₁
Δr = 5,831 - 5,099
Δr = 0.732 m
= Δr /λ
\frac{ \phi }{2\pi } = 0.732 / 0.487
\frac{ \phi }{2\pi } = 1.50
this is the phase difference this phase difference is approximately
Ф= =1.57,
so the interference is between destructive ( Ф = π) and constructive (Ф=2π)
Answer:
Melting, its like an ice cube(solid) melting in the sun into water(liquid)
Answer:
16 m / s
Explanation:
Average kinetic energy of one mole of a gas is given by the expression
K.E = 3 / 2 R T { T is absolute temperature of the gas }
Putting the values , we get
4070 = 3 / 2 X 8.312 X T
T = 326.35 K
Under similar condition temperature of oxygen will also be same . So temperature of oxygen gas will be 326.35 K.
Now ,RMS value of a gas =
T is absolute temperature of gas and M is molecular mass.
Molecular mass of oxygen is 32 gm . T is 326.35
RMS speed =
= 16 m / s . approx.
Power is the rate of work or energy. It has units of Watts. For an electrical circuit, it can be calculated by multiplying the voltage and the current flowing. Ampere represents the amount of electricity while voltage represents the force of the electricity flowing. We calculate as follows:
P = IV
P = 1 A (5x10^2 V)
P = 5x10^2 W
