Answer:
The force you need to apply would be 15 N.
Explanation:
To find the Force you need to apply, you have to use Newton´s second law (F = m x a).
F = m x a ⇒ F = 5 kg x 3 m/s²⇒ F = 15 N.
The force would be 15 N.
Answer:
<u>d) 1.8 atm</u>
Explanation:
<u>According to Boyle's Law,</u>
Here, we are given :
- <u>P₁ = 1.5 atm</u>
- <u>T₁ = 25°C = 298 K</u>
- <u>T₂ = 75°C = 348 K</u>
<u />
<u>Solving</u>
- P₂ = P₁T₂/T₁
- P₂ = 1.5 x 348 / 298
- P₂ = 522/298
- P₂ = <u>1.8 atm</u> (approximately)

Silicon is a popular semi-conductor. The process of doping either creates an excess or lack of electrons. In the case of silicon, the dopant is arsenic which has greater valence electron than silicon. Arsenic then donates an electron resulting to an excess of electrons. A new type or better type of semi-conductor is created. Silicon conduct greater electricity.
The best answer is the last option.
