A very light ideal spring having a spring constant (force constant) of 8.2 N/cm is used to lift a 2.2-kg tool with an upward acc

vampirchik [111]

Answer:

x = 3.5 cm

Explanation:

When spring is used as a lift tool

so the mass suspended on it will have spring force on it

So as per the force equation of mass we can say

$F_{net} = ma$

now net force on the mass is

$F_{net} = kx - mg$

$F_{net} = kx - mg = ma$

here we have

$kx = mg + ma$

now we have

$x = \frac{mg + ma}{k}$

$x = \frac{2.2(9.8) + 2.2(3.25)}{8.2}$

$x = 3.5 cm$

The surface of the paper is phosphorescent. When light shines on it, some of the energy is absorbed and re-emitted slowly over t

Ad libitum [116K]

Answer:

Explanation:

Recall that the hierarchy of wavelength color from minimum wavelength to maximum wavelength is:

$V < I < B < G < Y < O < R;$ and

$E \ \alpha \ \dfrac{1}{\lambda}$

As a result, blue light has a higher energy level than green and red light.

As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.

If there is a net force on an object in the direction it is already moving, what has to happen to the speed of the object?

baherus [9]

Net force is an unbalanced force, so the object will change speed or direction.
Either the object may speed up or slow down.
