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
Explanation:
Given that,
Let ABC is a triangle such that AB is perpendicular distance, BC is base and AC is the hypotenuse of triangle.
Let AB = 210 ft
AC = 90 + x
BC = x
To find :
The dimensions of the cornfield.
Solution :
Pythagoras theorem is used to find the value of x. It is given by :
On solving the above equation we find the value of x, x = 200 ft
So, BC = 200 ft
AC = 90 + 200 = 290 ft
So, the length, base and the hypotenuse of the triangle is 210 ft, 200 ft and 290 ft respectively.
Answer:
K = 483575 J
Explanation:
let K be the kinetic energy of the car and m be the mass of the car and v be the velocity of the car.
the kinetic energy is given by:
K = 1/2(m)(v^2)
= 1/2(1150)(29)^2
= 483575 J
Therefore, the kinetic energy of the sports car is 483575 J.
A common dry-cell battery is the zinc-carbon battery, which uses a cell that is sometimes called the Leclanché cell. The cell is made up of an outer zinc container, which acts as the anode
