Answer:
True
Explanations
Temperature is the degree of coldness or hotness of a body, usually organism rarely adapt to extreme temperature value of below 0°C or above 43°C,organisms usually respond to cold weather by hibernation or estivation for hot weather also extreme temperature causes migration of birds if they can't survive such place like the artic tern that travel thousands of miles,
My guess would be choice D
Answer:
It's constant everywhere in its trajectory.
Explanation:
the projectile was launched with an initial velocity, the only acceleration that is affecting the projectile's velocity is gravity.
The acceleration of gravity is practically equal everywhere on earth, so during its trajectory, we have to take into consideration only the acceleration because of gravity.
This is only correct because the projectile was launched with an initial velocity and it's not accelerating from rest and then falls.
Answer:
T = 2 T₀
Explanation:
To answer this question let's write the expression for electrical conductivity
σ = n e2 τ / m*
The relationship with resistivity is
ρ = 1 /σ
Whereby the resistance
R = ρ L / A = 1 /σ L / A
We see that there is no explicit relationship between time and resistance, there is only a dependence on the life time (τ) that depends on the properties of the material, not on its diameter or length.
As also the average velocity or electron velocity of electrons is constant, the time to cross 2 mm in length is twice as long as the time to cross a mm in length
T = 2 T₀
Answer:
Sun
Explanation:
The sun is Bigger than everything else.
