Answer:
The speed is maximum and the acceleration is zero
Explanation:
- The speed of the mass in simple harmonic motion can be found by using the law of conservation of energy. In fact, the total mechanical energy of the mass-spring system is sum of kinetic energy and elastic potential energy:
where
m is the mass
v is the speed
k is the spring constant
x is the displacement
As we can see, when the displacement is zero (x=0), the term representing the kinetic energy is maximum, so v (the speed) is also maximum.
- The acceleration of the mass in simple harmonic motion is proportional to the restoring force acting on the mass, which is given by Hook's law
where
k is the spring constant
x is the displacement
When x = 0, F = 0, so the net force acting on the mass is zero. Therefore, this also means that the acceleration of the mass is also zero: a = 0.
Valence electrons are outer shell electrons with an atom and can participate in the formation of chemical bonds. In single covalent bonds, typically both atoms in the bond contribute one valence electron in order to form a shared pair. The ground state of an atom is the lowest energy state of the atom
Answer:
The correct answer is in the x-axis direction, where the distance travelled is 1.0 cm and the surface is 8 .
Explanation:
The electrical resistance is lower when the contact surface is larger and the length is shorter.
An electrical resistance is an opposition to the flow of electric current through a conductor. For a given conductor, the resistance is given by the following formula:
R = ρ *
Where:
R: Electrical resistance.
ρ: Resistivity of the material.
l: Length.
S: Surface of the conductor.
Thus, the direction in which the electrical resistance is lower is when the distance is minimum and the area is greater.
Have a nice day!
<span>The answer would be Vestibular Senses.
Consciousness of body equilibrium and movement are checked by the vestibular
system. The vestibular senses (the feelings of
body rotation and of attraction and gravity) ascend in the inner ear; the sense
organs are the hair cells that give off signals done in the auditory nerve.</span>
A moment is not measured by the breaths we take, but by the moments that take our breath away
Also with time increments. (seconds minutes hours etc.)
