Answer:
0.076 kg
Explanation:
The force created by gravity can be found using mass x (9.8 m/s^2).
mg=0.750 N
m(9.8) = 0.750
Multiply both sides by 9.8: m = 0.076 kg
Los Angeles lies on the Pacific plate, San Francisco lies on the North American plate, and the meeting point of the two cities is mathematically given as
T = 120 x 105 years
<h3>What is the meeting point of the two plates?</h3>
Generally, the equation for Distance is mathematically given as
D = Rate x Time
Therefore
T = D/R
T = (600 x 105) / 5
T = 120 x 105 years
In conclusion, the meeting point of the two plates will be
T = 120 x 105 years

Answer: Troposphere
Explanation:
Fairly over the "surface" of Uranus lies the troposphere, where the atmosphere is the densest. The temperature ranges from a minus 243 degrees Fahrenheit (minus 153 degrees Celsius) to minus 370 F (minus 218 C) , with the upper regions being the coldest. This makes the atmosphere of Uranus the coldest within the solar system. Inside the troposphere are layers of clouds — water clouds at the least weights, with ammonium hydro sulfide clouds over them. Alkali and hydrogen sulfide clouds come following. At long last, lean methane clouds lay on the best. The troposphere amplifies 30 miles (50 kilometers) from the surface of the planet.
Using this information, we can determine that the Troposphere is the densest layer of Uranus's atmosphere.
Answer:
The correct answer is b, x = 9 cos (pi / 2 t)
Explanation:
The equation that describes a simple pendulum is
θ = θ₀ cos (wt + φ)
The angle is measured is radians
θ = x / L
We replace
d / L = x₀ / L cos (wt + φ)
x₀ = 9 in
We replace
d = 9 cos (wt + φ)
Angular velocity is related to frequency and period.
w = 2π f = 2π / T
The period is the time of a complete oscillation T = 4 s
w =2π / 4
w = π / 2
Let's replace
x = 9 cos (π/2 t + φ)
As the system is released from the root x = x₀ for t = 0 s
x₀ = x₀ cos φ
Cos φ = 1
φ = 0°
The final equation is
x = 9 cos (pi / 2 t)
The correct answer is b
