Answer: 38.25 m
Explanation:
In this situation we need to find the distance
between the rabbit and the carrot, and we can use the following equation, since the rabbit's acceleration is constant:
(1)
Where:
is the rabbit's maximum velocity (final velocity)
is the rabbit's initial velocity
is the rabbit's acceleration
is the distance between the rabbit and the carrot
Isolating
:
(2)
(3)
Finally:
You said T = 2 · π · √(L / g)
(I think that's the formula for the full-swing period of a simple pendulum.)
Divide each side by 2π : T/2π = √(L / g)
Square each side: (T/2π)² = L / g
Multiply each side by ' g ' : L = g · (T/2π)²
Answer:
They both describe atoms as being made up of positive and negative matter.
Explanation:
In both Bohr's model and Thomson model, the atom consists of positively-charged matter and negatively-charged matter. However, the structure of the atom in the two models is totally different:
- in Thomson's model, the atom consists of a large sphere of uniform positive charge, and electrons (which are negatively charged) are scattered all around inside this sphere
- In Bohr's model, the atom consists of a small, positively charged nucleus, while the electrons (negatively charged) orbit around the nucleus in precise orbits.
Answer:
The angle with the positive x axis 61.31°
Explanation:
It is given that, a vector in the x-y plane has a magnitude of 25 m and x component of 12 m.
x component of the vector, base = 12 m
Magnitude of hypotenuse, H = 25 m
We need to find the angle with the positive x axis. Let it is given by θ such that :


θ = 61.31°
So, the angle with the positive x axis 61.31°. Hence, this is the required solution.
