5 0

Explanation:

From the experiment:

      Number of protons  = 74

      Number of neutrons  = 110

Number of protons in an element is the atomic number of the element. It is used to locate and position and element on the periodic table.

For a neutral or uncharged atom, the number of protons is the same as the number of electrons.

The element whose number of protons or atomic number if 74 is Tungsten

  Mass number  = 74 + 110  = 184g/mol

A skateboarder is moving at 2.00m/s and increases his velcity at a rate of 1.6m/s/s for 6.0 seconds. What is the displacement of
MrRissso [65]

Answer:

S = 40.8m

Explanation:

<u>Given the following data;</u>

Initial velocity, u = 2m/s

Acceleration, a = 1.6m/s²

Time, t = 6secs

Required to find the displacement

Displacement, S = ?

The displacement of an object is given by the second equation of motion;

S = ut + \frac {1}{2}at^{2}

Where;

  • S represents the displacement measured in meters.
  • u represents the initial velocity measured in meters per seconds.
  • t represents the time measured in seconds.
  • a represents acceleration measured in meters per seconds square.

<em>Substituting into the equation, we have;</em>

S = 2*6  + \frac {1}{2}*(1.6)*6^{2}

S = 12 + 0.8*36

S = 12 + 28.8

S = 40.8m

<em>Therefore, the displacement of the skateboarder during this game is 40.8 meters. </em>

What is the potential energy of a 30 kg object that is 10 meters up on a ladder?
scZoUnD [109]

Answer:

<h2>3000 J</h2>

Explanation:

The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 30 × 10 × 10

We have the final answer as

<h3>3000 J</h3>

Hope this helps you
