Answer:
You would hear a loud trumpet sound that can be heard from a large distance.
Explanation:
Answer:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
Explanation:
The general kinematic equation for horizontal displacement is gives as:
Δx = v₀t + (1/2)at²
Where
Δx = change in the x direction
v₀ = initial velocity
t = time
a = acceleration
If the body is vertically instead of horizontally, Δx is changed to Δy
Δy = v₀t + (1/2)at²
For a vertical moving body, the acceleration it experiences is the gravitational accerelation of the earth 'g'
So the equation becomes:
Δy = v₀t + (1/2)gt²
where g = 9.81 m/s if the body is moving downwards and g = -9.81 m/s if the body is moving upwards
I dunno, I guess to see if you could get a different answer
1.It gives less load on the shaft.
2.It transmits more power than belts.
3.It may be used for both long as well as short distance.
By the half-life of radioactive, the remaining mass of radioactive elements is 2.47 pounds.
We need to know about the half-life of the radioactive elements to solve this problem. The radioactive element will decay over time and follow the equation
N = No(1/2)^(t/t'')
where N is the final quantity, No is the initial quantity, λ is the decaying constant, t is time and t'' is the half-life of a radioactive element.
From the question above, we know that
t'' = 9 years
No = 6 pounds
t = 11.5 years
Calculate the remaining mass
N = No(1/2)^(t/t'')
N = 6(1/2)^(11.5/9)
N = 2.47 pounds
