A. supplies energy to make charge flow
Answer: Symbol A
Explanation:
The four symbols described here represent:
- Symbol A shows two dots and a line draw from one not connected to the other. --> this is an open switch. A switch is component of a circuit that is used to open/close the circuit in order to interrupt/allow the flow of current through the circuit. In this case, the switch is open, since the line does not connect the second dot.
- Symbol B shows two dots and a line draw from one connected to the other. --> this is the symbol used to represent the switch when it is closed, so it is a closed switch.
- Symbol C shows vertical lines in the pattern long, short, long, and short with a plus and minus symbol on it. --> this symbol represents a battery, which consists of two or more cells and provides the electromotive force that pushes the electrons along the circuit.
Therefore, the correct symbol representing the open switch is
Symbol A
Answer:
red light light is an electromagnetic wave thats whyy
hope it helped
Explanation:
Assume orange is going from left to right and apple is going from right to left
If mv is the momentum of apple at angle θ to the x axis,
In the x direction
0.130*v cos θ = (0.170*1.23) -(0.130*1.08)
0.130*v cos θ = 0.0687-------------------------2
In the y direction
0.130*v sin θ = (0.170*0.974) = 0.16558--------------1
From 1 and 2
tan θ = 2.41
θ = 74.96º
Substituting the value of θ in
0.130*v cos θ = 0.0687
v = 1.38 m/s

Answer:
Explanation:
The question molded an ideal gas law, which state in part
"The Volume(V) of a gas is directly proportional to the absolute temperature(T) and inversely proportional to the pressure(P)"
Mathematically, this can be expressed as
where K is a constant. varying the value of k, we arrive at
using the first two expression of the above equation, where
Note, we have to convert the volume to
since
Now
also we convert the pressure from atm to pascal(pa)
convert back to atm
Hence the value of he final pressure is
1.8atm
