Answer with Explanation:
We are given that a transverse travelling wave on a cord is represented by

Where D and x in meters
t(in seconds)
a.General equation of transverse wave

By comparing we get
A=0.51


Wavelength,
b.
Frequency,
c.Velocity,
Direction:Towards negative x- axis
d.Amplitude,A=0.51 m
e.Maximum speed,
Minimum speed,
Completing the square gives the answer right away.


which indicates a maximum height of 87 when
.
<h2>Answer: polar covalent bonding</h2>
In polar covalent bonding, electrons are shared <u>unequally </u>between atoms, due to the unequal distribution of electrons between atoms of different elements, slightly positive and slightly negative charges appear in different parts of the molecule.
In this context, water molecule is an exellent example of this type of bonding:
Water (
) can stick to itself through hydrogen bonds, because a water molecule consists of 2 hydrogen atoms attached to 1 oxygen atom.
The oxygen atom tends to monopolize more electrons and keeps them away from hydrogen. Then, it can be said that a water molecule will have a negative side (oxygen) and a positive side (hydrogen).
Thanks to this polarity, water molecules can stick together with the formation of hydrogen bonds to attract a partial positive charge of hydrogen and a more electronegative atom, such as oxygen.
Answer:
I believe it's called rolling friction
Answer:Speed can be defined as
Explanation: B because if you think about it, 50 milers per hour means they are dividing the time it takes to drive a certain distance going that speed. So id has to be answer B! your welcome. Please upvote only if its correct!
