Answer:
Solid matter is composed of tightly packed particles. A solid will retain its shape; the particles are not free to move around. Liquid matter is made of more loosely packed particles. ... Gaseous matter is composed of particles packed so loosely that it has neither a defined shape nor a defined volume.\
Answer:
E = 15×10⁻²⁹ J
Explanation:
Given data:
Frequency of photon = 2.2× 10⁷ Hz
Energy of photon = ?
Solution:
Formula:
E = h.f
h = 6.63×10⁻³⁴ Js
by putting values,
E = 6.63×10⁻³⁴ Js × 2.2× 10⁷ s⁻¹
E = 14.586 ×10⁻²⁹ J
E = 15×10⁻²⁹ J
The energy of photon is 15×10⁻²⁹ J.
Answer:
no le entiendo pero si me se la respuesta ya tu sabe ✨✨✨✨
Answer: 26.25 miles per gallon
Explanation: first odometer reading = 65290
Second odometer reading = 65500
Difference in odometer reading = second reading - first reading
= 65500 - 65290 = 210 miles.
If it took 8 gallons to fill his tank, it means
8 gallons will get him 210 miles, therefore 1 gallon will get 210 miles/8gallons = 26.25miles/gallon. Hence he is getting 26.25miles/gallon.
