Marbles are exiting a container through a horizontal nozzle positioned 1.3 m above sandy ground. You notice that all the marbles land between 0.23 m and 0.41 m from the point directly below the end of the nozzle. What is the minimum initial speed of the marbles?

The minimum initial speed of the marbles are 2.6 m/s

Explanation:

Given that,

Height = 1.3 m

For vertical displacement,

We need to calculate the time

Using equation of motion

Put the value into the formula

We need to calculate the minimum initial speed of the marbles

Using formula of speed

Put the value into the formula

Hence, The minimum initial speed of the marbles are 2.6 m/s

answer; (d); skeletal muscles and sensory receptors;

wow this is going to be a long one

cats shouldn't be kept inside their whole life they should be out in nature in the fresh air but because of our technology advances it has become unsafe for our furry friend to be outside in the city's, because they could be hit by vehicles. in city's yes i agree being inside isn't the worse thing, but if you live somewhere rural you should let your cats outside, yes some animals hunt cats but i don't think cats should be kept inside confined to such a small space.

btw this is my opinion
