1) Beth rode the Flying Saucer ride at her favorite amusement park. The ride hung from a rod and swung back and forth while simu

#1

Since Beth rode the Flying saucer ride which is spinning on its axis while axis is moving to and fro as well, so here Beth will experience two motions in this case

(i) Spinning motion

(ii) Rotational motion

#2

Jill and Scott both traveled for 30 min

So time of motion for both is 0.5 h as we know that 1 h = 60 min

Now from the formula of speed we know that

$speed = \frac{distance}{time}$

Speed of Jill

$v_1 = \frac{5}{0.5} = 10 km/h$

speed of Scott

$v_2 = \frac{10}{0.5} = 20 km/h$

so correct answer is

B) Scott had the faster speed since he rode at 20 k/h while Jill only traveled 10 km/h.

#3

Since we know that <em>acceleration is rate of change in velocity</em>

So here we can say that every motion where velocity changes with time then it is an accelerated motion.

Now change in velocity occurs when either the magnitude will change or its direction will change because here velocity is a vector quantity and it will change with magnitude and direction both.

so here due to oval path the direction of velocity will changes at many points and hence it will be an accelerated motion.

so correct answer is

<em>C) James was right since the car changed direction during the race.</em>

A pendulum that moves through its equilibrium position once every 1.000 s is sometimes called a “seconds pendulum.” what is the

horrorfan [7]

The equilibrium position for a pendulum is straight down. If it moves through that position every second then its period is actually 2 seconds. This is because the period is how long it takes to go from one extreme and back again. It will pass through the equilibrium point twice when doing this. Once on the way down and again on the way back.

In order to distinguish between wavelengths independent of light intensity, one must have at least?

kirill [66]

One must have at least two visual pigments to distinguish between wavelengths independent of light intensity.

A substance that converts light energy into electrical potentials is called a visual pigment.

The basic structure of pigment consists of the chromophore, a colored molecule, and a protein called rhodopsin.

There are three types of visual pigments: Scotopsin, rhodopsins, and photopsin.

Scotopsin pigments are associated with vision and operate in less bright light while photopsin operates in a brighter light.

However, visual pigments are very significant substances as they are associated with vision and play a vital role in detecting light.
