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

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.

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 Seconds

Now, Speed = 1200 / 300 — Formula x

= 4 m/s

Hence, 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 Seconds

Hence, 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 Seconds

Finally, Velocity = 120 / 180

= 2/3 m/s

= 0.66 m/s

Hence, the Velocity of the object is 0.66 m/s.
