Answer:
Sabemos por definición que la fuerza es lo que es capaz de producir cambios o deformaciones en un cuerpo y a esto se denomina efecto estático y cuando la alteración ejerce movimiento o reposo se denomina efecto dinámico, con esta base resolvemos que:
-estirar un muelle: efecto estatico
- devolver una volea: efecto dinámico
- aplastar la plastilina: efecto estático
- empujar el carro del supermercado: efecto dinámico
- inflar un globo: efecto estático
Answer:
Yes
Explanation:
Velocity is a vector quantity, meaning it has size and direction, as opposed to speed, a scalar quantity which only has size.
An example is speed may be 30km/h, and an example of velocity is 30km/h East.
Therefore two people can have the same speed and different velocities because they can be traveling in different directions.
For example, you and your friend could be doing shuttles together but you started at one wall and they started at the other, so even though you are running at the same speed, you always have different velocities because they are running in the opposite direction as you.
Hope this helped!

Explanation:
Because the electroscope is made from conducting material, some of its electrons move up to the top of the electroscope to be near the charged rod when the rod is held close.
The infrared<span> (</span>IR<span>) and the </span>ultraviolet(UV<span>) represent the two extremities of the visible spectrum (400-700nm). While </span>IR<span> represents electromagnetic radiation
with wavelengths longer than those of visible </span>light<span>, </span>UV<span> represents wavelengths
shorter than visible </span>light<span>.

Explanation:
<u>Motion With Constant Acceleration
</u>
It's a type of motion in which the velocity of an object changes uniformly over time.
The equation that describes the change of velocities is:
Where:
a = acceleration
vo = initial speed
vf = final speed
t = time
Solving the equation for a:
The ball starts at rest (vo=0) and rolls down an inclined plane that makes it reach a speed of vf=7.5 m/s in t=3 seconds.
The acceleration is:
