<h2><u>Question</u><u>:</u><u>-</u></h2>
Ryan applied a force of 10N and moved a book 30 cm in the direction of the force. How much was the work done by Ryan?
<h2><u>Answer:</u><u>-</u></h2>
<h3>Given,</h3>
=> Force applied by Ryan = 10N
=> Distance covered by the book after applying force = 30 cm
<h3>And,</h3>
30 cm = 0.3 m (distance)
<h3>So,</h3>
=> Work done = Force × Distance
=> 10 × 0.3
=> 3 Joules
Answer:
Shape, Volume
Higher Density
Strong Force
Solids have a higher melting point
The diffusion is slow for another solid

Use the formula t = d/v
t = 15 km/ 37 km/h
t = 0.4054
t = 0.41 h (rounded)
Density equals mass over volume. density= 196/(68-45)
density=4.4 g/cm3
