Answer:
that there would be more clouds.
Explanation:
one of the cycles is precipitation. without water there would be no rain and clouds are what causes the rain to come down
Answer:
the anwser is The healthy adult golden eagle, due to its impressive size and hunting prowess, has no natural predators. Eggs, chicks, immature eagles, and injured birds are susceptible to a range of predators, such as other birds of prey, including other kinds of eagles and hawks, bears, wolves and cougars.
Explanation:
Answer:
The correct answer is B
Explanation:
To calculate the acceleration we must use Newton's second law
F = m a
a = F / m
To calculate the force we use the defined pressure and the radiation pressure for an absorbent surface
P = I / c absorbent surface
P = F / A
F / A = I / c
F = I A / c
The area of area of a circle is
A = π r²
We replace
F = I π r² / c
Let's calculate
F = 8.0 10⁻³ π (1.0 10⁻⁶)²/3 10⁸
F = 8.375 10⁻²³ N
Density is
ρ = m / V
m = ρ V
m = ρ (4/3 π r³)
m = 4500 (4/3 π (1 10⁻⁶)³)
m = 1,885 10⁻¹⁴ kg
Let's calculate the acceleration
a = 8.375 10⁻²³ / 1.885 10⁻¹⁴
a = 4.44 10⁻⁹ m/s² absorbent surface
The correct answer is B
Answer:
k = 0.292 N / m
Explanation:
The glider with the spring forms a system with a simple harmonic movement, in this type of movement the angular velocity is given by
w = √ k / m
The angular velocity is related to the frequency and is related to the period
w = 2π f
f = 1 / T
We replace
2π / T = ra (k / m
T = 2π √ (m / k)
The period is the time of a complete oscillation, in this case the glider starts from the equilibrium point and returns for the first time, this corresponds to the middle of the period
½ T = 2.60 s
T = 2 2.60
T= 5.20 s
We clear the equation
T² = 4π² m / k
k = 4π² m / T²
Let's calculate
k = 4π² 0.200 / 5.20²
k = 0.292 N / m
Answer:
n=2,3
Explanation:
We have to take into account the expression for the fundmentals modes in a vibrating cord
in this case we have resonant at 880Hz and 1320Hz
Hope this helps!!
