Answer:
Two stars (a and b) can have the same luminosity, but different surface area and temperature if the following condition is met:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
Explanation:
The luminosity of a star is the total energy that produces in one second. It depends on the size of the star and its surface temperature.
L = σ(T^4)(4πR^2)
L is the luminosity f the star, T is the temperature of the surface of the star and R is its radius.
Two stars can have the same luminosity if the relation between the radius and the surface temperature is maintained.
To see this lets suposed you have 2 stars, a and b, and the luminosities of each one of them:
L_a = σ(T_a^4)(4πR_a^2)
L_b = σ(T_b^4)(4πR_b^2)
you can assume that L_a and L_b are equal:
σ(T_a^4)(4πR_a^2) = σ(T_b^4)(4πR_b^2)
Now, you can cancel the constants:
(T_a^4)(R_a^2) = (T_b^4)(R_b^2)
as long as this relation between a and b is true, then the luminosity can be the same.
Answer:
IPM is an environment-based approach that emphasizes long-term pest reduction or harm through a blend of strategies such as biological control, habitat alteration, cultural practices adjustment, and the use of resistant varieties.
Explanation:
IPM is an environment-based approach that emphasizes long-term pest reduction or harm through a blend of strategies such as biological control, habitat alteration, cultural practices adjustment, and the use of resistant varieties.
6 major components which are common to every IPM programs:
1 ) Pest identification
2) Monitoring and assessment of the number of plagues and damage.
3) Guidelines for when management practice or action is required
4) Prevent pest problems
5) Use of a blend of tools for biological, cultural, physical/mechanical and chemical management
6) Assessment of the impact of pest control after action
Explanation:
Except in the crust, the interior of the Earth cannot be studied by drilling holes to take samples. Instead, scientists map the interior by watching how seismic waves from earthquakes are bent, reflected, sped up, or delayed by the various layers.
because they're different ways
Climate change is going to happen, because even without humans Earth's climate changes over time. Global warming is where green house gasses are caught in our atmosphere and the earth gradually warms up. Global warming can be stopped, or a least slowed, but climate change will happen no matter what.
