He found that elements could not be broken into simpler substances but compounds could.
Where the air has low humidity
idk ;-; you can do it!
<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: 340 m/s
explanation: in this instance, the sound wave travels 340 meters in 1 second, so the speed of the wave is 340 m/s. remember, when there is a reflection, the wave doubles its distance. in other words, the distance traveled by the sound wave in 1 second is equivalent to the 170 meters down to the canyon wall plus the 170 meters back from the canyon wall.
Answer:
the thermal energy transferred is 183,226.68 J
Explanation:
Given;
mass of iron skillet, m = 5.1 kg
initial temperature, t₁ = 295 K
final temperature, t₂ = 373 K
The thermal energy transferred is calculated as;
Q = mcΔt
where;
Δt is change in temperature, = t₂ - t₁
c is specific heat capacity of iron = 460.6 J/kg.K
Q = 5.1 x 460.6 x (373 - 295)
Q = 183,226.68 J
Therefore, the thermal energy transferred is 183,226.68 J
