A 4.03 x 10-5 F capacitor stores 5.15 x 10-3 J of energy. What is the voltage across the capacitor?
Answers
Answer:
V = 0.06255 Volts
Explanation:
Given the following data;
Capacitance = 4.03 * 10^{-5} F
Energy = 5.15 * 10^{-3} J
To find the voltage across the capacitor;
Mathematically, the energy stored in a capacitor is given by the formula;
E = ½cv²
Where;
C is the capacitor
E is the energy stored
v is the voltage.
Substituting into the formula, we have;
5.15 * 10^{-3} = ½ * 4.03 * 10^{-5} * v²
0.00515 = 0.00002015 * v²
V² = 0.00002015/0.00515
V² = 0.003912
Taking the square root of both sides, we have;
V = √0.003912
V = 0.06255 Volts

Mr Mann cut a cucumber. Mr Mann said, you have performed a chemical change. Is he right?
Answers
Answer:
No.
Explanation:
The cut cucumber is still a cucumber.
Answer:
Nope.
Explanation:
Chemical change is transforming the cucumber into a pickle. However, you need vinegar, so it isn't a full change.
Therefore, Mr. Mann would not be right either way, because all he did was cut a cucumber, and he should probably get some help with all this "chemical change".

A wire carries a current of 6.52 A in a direction that makes an angle of 44.8 degrees with the direction of a magnetic field of strength 0.258 T. What is the magnetic force on a 3.61 m length of wire
Answers
Answer:
[tex]F=4.27N[/tex]
Explanation:
From the question we are told that:
Current [tex]I = 6.52 A[/tex]
Angle [tex]\theta= 44.8 \textdegree[/tex]
Magnetic field [tex]B= 0.258 T.[/tex]
Length [tex]l=3.61m[/tex]
Generally the equation for Magnetic force F is mathematically given by
[tex]F=BIlsin\theta[/tex]
Therefore
[tex]F=0.258*6.52*3.61*sin 44.8[/tex]
[tex]F=4.27N[/tex]
The light intensity incident on a metallic surface with a work function of 1.88 eV produces photoelectrons with a maximum kinetic energy of 1.2 eV.
if the frequency of the light is doubled, what is the maximum kinetic energy of the photoelectrons?
Answer in units of eV.
Answers
Answer:
KE = KE (incidental) - KE of emitted photons
or KE = h * f - Wf
So h * f = KE + Wf = 1.2 + 1.88 = 3.08 incident energy
If you double the frequency then h * f = 6.16
KE = 6.16 - 1.2 = 4.96 eV

these 3 questions please. its due in 20 minutes thank you buddy if you answered
Answers
Answer:
convert five min into sec
=5*60
=300 sec
speed=distance/time taken
=1200m/300s
=4m/s
speed=distance/time taken
5m/s=2000m/time taken
5*time taken=2000m
time taken =2000m/5m/s
time taken =400 sec
convert 3 min to second
=3*60
=120 sec
velocity=120/120
=1m/s
Explanation:
The formula that'll be used for all these questions–
Speed = Distance / Time — x
Or, Distance/ Speed = Time — y
________________________________
Well, here–Distance = 1200 Meter
Time = 5 minutes
= 5 × 60= 300 SecondsNow, Speed = 1200 / 300 — Formula x
= 4 m/sHence, the speed of the car is 4 m/s.
________________________________
2– Now, here–Speed = 5 m/s
Distance = 2000 Meter
Time Taken = 2000 / 5 – Formula y
= 400 SecondsHence, the time taken by the car for the journey is 400 seconds.
________________________________
3– Then here,We know that Velocity = Displacement / Time
By the way, the distance traveled in a straight line is called displacement.
And, speed is a definite direction is called velocity.
Now Here, Displacement = 120 meters
Time = 3 Min= 3 × 60= 180 SecondsFinally, Velocity = 120 / 180
= 2/3 m/s= 0.66 m/sHence, the Velocity of the object is 0.66 m/s.

the total resistance of the circuit
Answers
The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.
If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω
Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather than add to make the total.
Answer: 3
Explanation: If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.
