To solve this problem we will apply the second law of kinematics that describes the position as a function of speed, time and its acceleration, as
Here,
= Initial velocity
t = Time
a = Acceleration
Our values are,
Replacing we have that
From this expression we could determine the position traveled, without considering that the given speed is the same assumed in the term of acceleration. Under this consideration we would have to v = 4m / s
We are given with a force in the middle of a rope measuring 10 m and an angle of sagging of 10 degrees from the horizontal. The tension of the rope is equal to the hypotenuse of the right triangle.
sin 10 = 50 kg * 9.8 m/s2 / T
Tension = 2821. 80 N
An atom in normal conditions refers when electrons are in the fundamental state. When you leave the atom, an electron absorbs energy from an external source and moves to a higher energy state.
Energy states or energy levels are called orbitals. The difference between the energy states in an atom is responsible for the emission of photons when an electron transition occurs between these two energy states.
Because the energy levels are discrete, the emitted photons also possess different energies.
Answer: my ecosystem
Explanation:the ecosystem I want to live in is one with nature that you can eat witch tastes good and with animals that you can talk to. I would love to live in an ecosystem like that.
Hello.
h=150 m
u(initial speed)=0
t=5.5 s
<span>v(final speed) =?
</span>
2gh=v^2-u^2
Have a nice day
