Answer:
1010713.18851 Pa
387999.259089 N
Explanation:
= Atmospheric pressure =
r = Radius = 2 m
h = Depth = 10 m
= Density of liquid methane =
g = Acceleration due to gravity = 7.44 m/s²
A = Area
Force is given by
The force exerted is 1010713.18851 Pa
The weight of the column of methane is 387999.259089 N
The pressure at a depth is given by
The pressure at the depth is
Answer:
The correct answer is B.
Explanation:
Step 1:
The available regression equation is: Predict height= 0.29 + 0.48 (age).
Here, the predict height is dependent variable and the age is in-dependent variable.
Intercept = 0.29
Slope = 0.48
The given regression equation indicates the y on x model and the intercept coefficients of the regression equation is 0.29 and the slope is 0.48.
Step 2:
The height increases, an average, by 0.48 m per year.
Because co-efficient of slope variable indicate the positive sign and we increase 1 year in age then automatically height increased is 0.48 m.

The height increases, on average, by 0.48 meter each year.</h3>
Answer:
#_time = 7.5 10⁴ s
Explanation:
In order for the astronaut to be younger than the people on earth, it follows that the speed of light has a constant speed in vacuum (c = 3 108 m / s), therefore with the expressions of special relativity we have.
t =
where t_p is the person's own time in an immobile reference frame,
let's calculate
we assume that the speed of the space station is constant
t_ = 0.99998666657 s
therefore the time change is
Δt = t - t_p
Δt = 1 - 0.9998666657
Δt = 1.3333 10⁻⁵ s
this is the delay in each second, therefore we can use a direct rule of proportions. If Δt was delayed every second, how much second (#_time) is needed for a total delay of Δt = 1 s
#_time = 1 / Δt
#_time =
#_time = 7.5 10⁴ s
Answer:
1000 Kilograms
Explanation:
Force is equal to mass times acceleration so if the force is 3000 and the acceleration is 3 m/s^2 then all you need to do to find the mass is divide 3000 by 3 which gives you 1000
Answer:
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
Example: Radio waves, microwaves, visible light, and x rays
