PLEASE HELP... 100 POINTS....

Physics
1 answer:
kirill [66]3 years ago

Answer: 20 m/s in 2 significant figures.

Explanation:

Initial velocity (u) = 0 m/s

Acceleration by gravity (a) = 9.81 m/s^2

Displacement (s) = 20m

Final velocity (v) = ?

Now, use formula

v^2 = u^2 + 2 * a * s

or, v^2 = 0^2 + 2 * 9.81 * 20

or, v = square root of( 2 * 9.81 * 20 )

So, v = 20 m/s in 2 significant figures.

If i were a professional working in Geology, i would’ve question alfreds theory considerably. His proof was pretty reasonable though so I would’ve read through it and checked myself befor I believed anything.. with that being said I think I wouldn’t have believed him at first but eventually I would’ve.

In many ways the Sun is an average star. What is something unique about the Sun?
Fudgin [204]
 The Sun keeps the planets in orbit, using it's own gravitational pull. IT also powers every planet, allowing plants to thrive and people to live.

Fantom [35]

Answer:

V₀ₓ = 10.94 m/s

V₀y = 18.87 m/s

Explanation:

To find the launch velocity, we use 1st equation of motion.

Vf = Vi + at

where,

Vf = Final Velocity of Ball = Launch Speed = V₀ = ?

Vi = Initial Velocity = 0 m/s (Since ball was initially at rest)

a = acceleration = 376 m/s²

t = time = 0.058 s

Therefore,

V₀ = 0 m/s + (376 m/s²)(0.058 s)

V₀ = 21.81 m/s

Now, for x-component:

V₀ₓ = V₀ Cos θ

where,

V₀ₓ = x-component of launch velocity = ?

θ = Angle with horizontal = 59.9⁰

V₀ₓ = (21.81 m/s)(Cos 59.9°)

<u>V₀ₓ = 10.94 m/s</u>

<u></u>

for y-component:

V₀ₓ = V₀ Sin θ

where,

V₀y = y-component of launch velocity = ?

θ = Angle with horizontal = 59.9⁰

V₀y = (21.81 m/s)(Sin 59.9°)

<u>V₀y = 18.87 m/s</u>

<u></u>

How do the nonliving parts of earth's systems provide the basic materials to support life?
MatroZZZ [7]
The abiotic community of the ecosystem or the nonliving objects in the earth's biosphere influences the survival, growth and development of the organism. They provide basic mmaterials to support life by the biogeochemical processes which is composed of many biological and environmental cycles which profoundly has factored the intiation and continuation of life on earth. They also provide the basic materials to support life by the undergoing process which is also initiated by the living creatures or the biotic society of the ecosystem.
