Answer:
The difference of power is
ΔP = 172.767 kPa
Explanation:
ρ = 1390 kg / m³
v = 9.63 m/s
d₁ = 10.1 cm , d₂ = 15.3 cm
Δz = 8.85 m
To find the difference ΔP between the fluid pressure at locations 2 and the fluid pressure at location 1
ΔP = ρ * g * Z + ¹/₂ * ρ * v² * ( 1 - (d₁ / d₂)⁴ )
ΔP = 1390 kg / m³ * 9.8 m/s² * 8.85 m + 0.5 * 1390 kg / m³ *(9.63 m /s)² * (1 - (0.101 m / 0.153 m )⁴ )
ΔP = 172.767 x 10 ³ Pa
ΔP = 172.767 kPa
Answer:
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
Explanation:
Given;
wavelength = 6.33 x 10^-7 m
Speed of light v = 3.0 x 10^8 m/s.
Frequency of the laser light f
= speed of light/wavelength
Substituting the given values;
f = 3.0 x 10^8 m/s ÷ 6.33 x 10^-7 m
f = 4.76 × 10^14 Hz
Frequency of the laser light f = 4.76 × 10^14 Hz
The answer is C. Electrical;mechanical
1 Newton is equal to the amount of force required to accelerate an object at a rate of 1 metre per second, every second. One newton is the force needed to accelerate one kilogram of mass at the rate of one metre per second squared in direction of the applied force.
It affects basketball in a way called traction.
The friction between the players' basketball shoes and the hard wooden floor is traction, or friction. Without it, players would slide everywhere and wouldn't be able to play the game.
