5 0

Answer:

50N

Explanation:

Impulse = Force × Time

25 = Force × 0.5

Force = 25/0.5

= 50N

inysia [295]

Answer:

PRO'S OF SOLAR ENERGY: reduced electricity bills, low maintenance cost, renewable energy source.

CONS OF SOLAR ENERGY: Cost, relies on weather, takes up a lot of space.

PROS OF WIND ENERGY: Clean environment, cost effective, Free

CON'S OF WIND ENERGY: Wind turbines are noisy, strength of wind is not always reliable

PROS OF GEOTHERMAL ENERGY: Save about 30% - 60% on heating and cooling, not weather dependent.

CONS OF GEOTHERMAL ENERGY: Greenhouse emission, high investment cost, requires a lot of land.

PROS OF BIOMASS ENERGY: Reduced dependence on fossil fuels, carbon neutral, waste reduction.

CONS OF BIOMASS ENERGY: Emissions, deforestation. cost.

PROS OF HYDROELECTRIC ENERGY: Good for the environment, reliable, efficient.

CONS OF HYDROELECTRIC ENERGY: Expensive, not always safe, you can't place hydroelectric energy anywhere you want.

Calculate the ratio of the drag force on a passenger jet flying with a speed of 950 km/h at an altitude of 10 km to the drag for
gulaghasi [49]

Answer:

14.18

Explanation:

given,

Speed of passenger jet,v₁ = 950 Km/h

Altitude of flight, h₁ = 10 km

Prop-driven speed,v₂ = 950/5 = 190 Km/h

altitude,h₂ = 5 Km

density of air at 10 Km = 0.38 Kg/m³

density of air at 5 Km = 0.67 Kg/m³

Drag force formula

F = \dfrac{1}{2}C\rho Av^2

now, ratio of drag Force

\dfrac{F_{jet}}{F_{prop}}=\dfrac{\dfrac{1}{2}C\rho_{10} Av_{1}^2}{\dfrac{1}{2}C\rho_{5} Av_2^2}

\dfrac{F_{jet}}{F_{prop}}=\dfrac{\rho_{10} v_{1}^2}{\rho_{5}v_2^2}

\dfrac{F_{jet}}{F_{prop}}=\dfrac{0.38\times 950^2}{0.67\times 190^2}

\dfrac{F_{jet}}{F_{prop}}=14.18

Hence, the ration of the drag force is equal to 14.18.
