Answer:
150 million kilometres
Explanation:
The astronomical unit (symbol: au, or AU or AU) is a unit of length, roughly the distance from Earth to the Sun and equal to 150 million kilometres (93 million miles) or 8.3 light minutes.
Suspect and mounts are a solid frame. True.
Kinetic energy = 1/2mv^2
=1/2(25)(1^2)
= 12.5J
Answer:
55000 W/m²
Explanation:
Parameters given:
Surface temperature, T = 1000°C
Hear transfer coefficient, h = 55 W/m²C
Convection heat transfer coefficient is given as:
h = Heat flux/Temperature
Hence, Heat Flux, q, is given as:
q = h * T
q = 55 * 1000 = 55000 W/m²C
Answer:
L = 6 cm
Explanation:
Second overtone of the wire is same as third harmonic
so its frequency is given as
here we know that
now we have
Now fundamental frequency of sound in a pipe is given as
