Given:
heat generated by John's cooling system, = 45 W (1)
If ρ, A, and v corresponds to John's cooling system then let be the variables for Mike's system then:
Formula use:
Heat generated,
where,
= density
A = area
v = velocity
Solution:
for Mike's cooling system:
=
⇒ = × A ×
= 4.513 A
Using eqn (1) in the above eqn, we get:
= 4.513 × 45 = 203.09 W
Answer:
PEgrav = m *• g • h
Explanation:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
Hope this helps
Answer:
The wavelength will be 4 cm, frequency will be 4.66 Hz and wave speed is 18.6 cm/sec
Explanation:
Given:
No. of crest = 13
No. of trough = 15
Time = 3 seconds
Hence, 1 crest or 1 trough =
therefore,
13 C + 15 T =
=
Time given 3 seconds
=
2 cm distance is travelled is time period
Again wave will travel in 1 T = 4 cm
wave speed v =
=
= 18.6 cm/s
