A bicyclist is traveling at a speed of 20.0 m/s as he approaches the bottom of a hill. He decides to coast up the hill and stops
Rudiy27

Answer:

Vertical height of the hill, h = 20.4 meters

Explanation:

Given that,

Speed of the bicyclist, v = 20 m/s

To find,

The vertical height of the hill.

Solution,

Let h is the height of the hill. When he approaches the bottom of the hill, the loss in kinetic energy is equal to the gain in potential energy. Using the conservation of energy as,

\dfrac{1}{2}mv^2=mgh

h=\dfrac{v^2}{2g}

h=\dfrac{(20)^2}{2\times 9.8}

h = 20.4 meters

Therefore, the vertical height of the hill is 20.4 meters. Hence, this is the required solution.

Answer:

Electron shell

Nucleus

Neutrons

Explanation:

An atom is made up of three fundamental subatomic particles which are the protons, neutrons and electrons.

  • Protons are the positively charged particles. Neutrons do not carry any charges.
  • Both protons and neutrons are found in the tiny nucleus at the center of that atom.
  • The electrons are negatively charged.
  • They are found outside the nucleus in electronic shells.

Help me please, help
Alisiya [41]

Answer:

455,000 Pa

Explanation:

PV = nRT

If n is constant:

PV / T = PV / T

(101,325 Pa) (718 mL) / (273 K) = P (175 mL) / (26 + 273) K

P = 455,000 Pa

A worker pushes a 1080 N crate with a horizontal force of 345 N a distance of 14 m. Assume the coefficient of kinetic frictin be
amm1812

Answer:

The work done by the worker on the crate is 4830 J.

Explanation:

Given that,

Force = 1080 N

Horizontal force = 345 N

Distance d = 14 m

Coefficient of friction = 0.22

We need to calculate the work done

Using formula of work done

W = Fd

F = force

d = distance

Put the value into the formula

W=345\times14

W=4830\ J

Hence, The work done by the worker on the crate is 4830 J.
