Answer:
1.7 J
Explanation:
The energy carried by a single photon is given by
E=hf
where h is the Planck's constant and f is the frequency of the photon.
The photon of our exercise has a frequency of f=1.7 \cdot 10^{17} Hz, therefore its energy is
E=hf=(6.63 \cdot 10^{-34}Js)(1.7 \cdot 10^{17} Hz)=1.1 \cdot 10^{-16} J
No becuase a round room has no corners so no
<span>It is possible to determine which cart to which ch is connected if the graph would show electrical charge, ie, amps or voltage. If the graph showed a series circuit diagram this would also allow determination. Bottom line is that a correct graph data will show the requested information.</span>
Answer:
(a): The car's relative position to the base of the cliff is x= 32.52m.
(b): The lenght of the car in the ir is tfall= 1.78 sec.
Explanation:
Vo= 0
V= ?
d= 50m
h= 30m
a= 4 m/s²
t= √(2*d/a)
t= 5 sec
V= a*t
V= 20 m/s
Vx= V * cos(24º)
Vx= 18.27 m/s
Vy= V* sin(24º)
Vy= 8.13 m/s
h= Vy*t + g*t²/2
clearing t:
tfall= 1.78 sec (b)
x= Vx * tfall
x= 32.52 m (a)
Answer:
These are a part of lab procedures:
1. Write a hypothesis to answer a question.
2. Write a title at the top of a completed lab report.
3. Record the time to complete a chemical reaction.
These are NOT a part of lab procedures:
1. Create a question on the cause of a chemical reaction.
