Answer:
Volumetric flow rate = 0.024 m³/s
Explanation:
Volumetric flow rate = Discharge = Q
We have expression for discharge, Q = Area ( A) x Velocity (v)
Velocity , v = 3 m/s
Substituting
Discharge, Q =Av = 7.85 x 10⁻³ x 3 = 0.024 m³/s
Volumetric flow rate = 0.024 m³/s
Answer:
The value is
Explanation:
From the question we are told that
The power output from the sun is
The average wavelength of each photon is
Generally the energy of each photon emitted is mathematically represented as
Here h is the Plank's constant with value
c is the speed of light with value
So
=>
Generally the number of photons emitted by the Sun in a second is mathematically represented as
=>
=>
Abiogenesis is the name of life on Earth.
Answer:
0.03 T
Explanation:
The magnetic field B at the center of a solenoid is given by B = μ₀Ni/L where
μ₀ = permeability of free space = 4π × 10⁻⁷ H/m, N = number of turns of solenoid = 5000 turns, i = current in solenoid = 5 A and L= length of solenoid. Since we are not given length of solenoid, let us assume it is 1 meter. So, L = 1 m
So, B = μ₀Ni/L
= 4π × 10⁻⁷ H/m × 5000 turns × 5 A/1m
= 4π × 10⁻⁷ H/m × 25000 A-turns/m
= 314159.27 × 10⁻⁷ T
= 0.031415927 T
≅ 0.03 T
