Answer:

Answer below!!

Explanation:

In short,the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time,roughly 13.8 billion years ago.At this time,all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.

Do animals fart and do all animals blink and do animals have the same trait of humans
pantera1 [17]
Uh yes they do fart and blink. Like very living person, and animal. They do have the same traits, as that to humans, but their biology is set up differently. They are stronger and quicker.
I'm not going to state that humans are animals, because I don't agree. Humans are NOT animals!!! But that's my belief, oppose as you like.
I think the best way to answer this question, is to imagine being an animal. Possibly a wild animal. What do you do? How do you find food? Where do you sleep? See, usually humans know how to be disgusted about living in unsanitary and unsafe environments. I mean looking at the traits, they're biology is just set up differently from humans.

I hope this helps.<span />

A projectile fired from a gun has initial horizontal and vertical components of velocity equal to 60 m/s and 80 m/s, respectivel
DerKrebs [107]

This question involves the concepts of projectile motion and launch speed.

(a) The initial launch speed of the projectile is "100 m/s".

(b) The launch angle of the projectile is "53.13°".

<h3>(a) LAUNCH SPEED</h3>

A projectile motion is a motion that takes place on both x and y axes, simultaneously. In this motion the initial launch speed is given by the following formula:

v_o=\sqrt{v_{ox}^2+v_{oy}^2}

where,

  • v_o = initial launch speed = ?
  • v_{ox} = horizontal component of initial launch speed = 60 m/s
  • v_{oy} = vertical component of initial launch speed = 80 m/s

Therefore,

v_o = \sqrt{(60\ m/s)^2+(80\ m/s)^2}\\\\v_o = 100 m/s

<h3>(b) LAUNCH ANGLE</h3>

Launch angle is given by th following formula:

\theta = tan^{-1}(\frac{v_{oy}}{v_{ox}})=tan^{-1}(\frac{80\ m/s}{60\ m/s})\\\\\theta=53.13^o

If you shout into the grand canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back, and
Nostrana [21]
Given:
The speed of sound is  340 m/s
Time for the echo is 5.2 s.

Let h = the depth of the canyon.

Because the sound of your voice travels to the bottom of the canyon and back to your ear, the total distance traveled is 2h.

By definition,
distance = velocity * time.
Therefore
2h = (340 m/s)*(5.2 s) = 1768 m
h = 884 m

Answer: The depth is 884 m.
