y rotate overhead, from east to west. B) viewing them from the surface of the rotating Earth. C) also moving on Earth in the same direction, east to west. D) orbiting on Earth around the Sun and nothing is really stationary.

The basketball coach tells his team to run sprints back and forth across the court, which is 30 m long. They start at the left e
sp2606 [1]

Distance is the total length of an object's path. Displacement is the overall change in position, ie. how far an object is from its initial position.


The court is 30 m long, so a path going back and forth once is 60 m long. Going along this path 6 times totals 360 m.


The end point is the same as the starting point, so the displacement is 0 m.

What’s the dependent variable?
Nikolay [14]

Answer: number of bacteria

Explanation:

A easier way. I like to remember it is that x axis = independent and yaxis = dependent variable, but if that doesn’t help think about this

Why would the number of bacteria effect the amount of time. It doesn’t make sense because time goes on forever and nothing can change about it but time can change the number of bacteria because if you had a timer of 30 seconds and the bacteria is for example 10 and if you had a timer of one minute then the number of bacteria change because of time, if you flip it, it doesn’t make sense

How long( in hours, will it take for 500 000 C of charge to flow through a diode if it requires
Alina [70]

Answer:

277.78 hours

Explanation:

The formula for calculating the amount of charge is expressed as;

Q = It

I is the current

t is the time

Given

I =0.05A

Q = 50,000C

Required

Time t

Recall that: Q = It

t = Q/I

t = 50,000/0.05

t = 1,000,000secs

Convert to hours

1,000,000secs  = 1,000,000/3600

1,000,000secs = 277.78 hours

Hence it will take 277.78 hours for the charge to flow through the diode

A balloon will stick to a wooden wall if the balloon is charged
grigory [225]
<h2>Answer: either way</h2>

The balloon contains neutral charge atoms, that is, it has the same number of electrons (negative charge), protons (positive charge) and neutrons (no charge).

Then, when two objects come into contact, the electrons of one of them can become part of the other.

Thus, by bringing the balloon closer to the wall, the wall, which is also made up of atoms, will reorder its charges in such a way that its electrons or protons become part of the balloon, charging it.
