An eagle is flying horizontally at a speed of 3.1 m/s when the fish in her talons wiggles loose and falls into the lake 5.8 m below. a. calculate the magnitude of the velocity of the fish relative to the water when it hits the water in m/s.
b. calculate the angle, in degrees, by which the fish's velocity is directed below the horizontal when the fish hits the water.

11.101 m/s

Explanation:

Given

Velocity of eagle=3.1 m/s

Eagle is at height of 5.8 m

Fish is dropped with a horizontal velocity of 3.1 m/s

time taken by fish to reach lake is

here u=0 (vertical velocity)

t=1.087 s

Vertical velocity acquired by fish is v=u+at

Horizontal velocity=3.1 m/s

Therefore net velocity

below horizontal

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
