what is the power of lens having focal length 6 cm?
Yes Convex Lens Can form virtual images which are magnified, provided the object distance, measured from the optical centre must be less than focal length.
For your question,
let focal length, f = + 6 cm
let object distance be 'u'
let image distance be 'v'
magnification required, m = +3, +ve because image will be erect, according to the property of convex lens:
A circuit contains a 20-Ohm resistor and an inductor with an inductance of 0.093 H. If the circuit has a frequency of 60 Hz, what is the total impedance of the circuit?
Answer:
Explanation:
The computation of the total impedance of the circuit is shown below:
The Total impedance of the circuit is

where
X_L^2 = 2πfL
= (2π) (60Hz) (0.093 H)
= 35.06 Omega
Now put the value of X_L^2 in the above formula

Explain how that energy converts itself from POTENTIAL to KINETIC energy.
Answer:
Potential energy can transfer into other forms of energy like kinetic energy. Kinetic energy is energy an object has because of its motion.
Explanation:
The ball was released, as the ball moves faster and faster toward the ground, the force of gravity will transfer the potential energy to kinetic energy.
An 1876 N crate is being pushed across a level force at a constant speed by a force of 747 N. What is the coefficient of kinetic friction?
0.16
0.40
0.08
not enough information
The crate only moves horizontally, so its net vertical force is 0. The only forces acting in the vertical direction are the crate's weight (pointing downward) and the normal force of the surface on the crate (pointing upward). By Newton's second law, we have
∑ F (vertical) = n - mg = 0 → n = mg = 1876 N
where n is the magnitude of the normal force.
In the horizontal direction, the crate is moving at a constant speed and thus with no acceleration, so it's completely in equilibrium and the net horizontal force is also 0. The only forces acting on it in this direction are the 747 N push (pointing in the direction of the crate's motion) and the kinetic friction opposing it (pointing in the opposite direction). By Newton's second law,
∑ F (horizontal) = 747 N - f = 0 → f = 747 N
The frictional force is proportional to the normal force by a factor of the coefficient of kinetic friction, µ, such that
f = µn → µ = f / n = (747 N) / (1876 N) ≈ 0.398188 ≈ 0.40

what would happen if a paper clip that is not a permanent magnet was brought close to the south pole of a permanent magnet?
Answer:
Because this pole is different from the original pole that magnetized the paperclips, the top paperclip will become demagnetized in the opposite direction and the bottom paperclip will be repelled away
Many battery-powered devices come with cords that allow them to be
plugged into electrical outlets. What change has to take place inside
the power cord in order for the device to function properly?
Answer:
The change that has to take place inside the power cord in order for the device to function properly include;
The changing of the alternating current (AC) from the electrical outlet to the direct current having a specific voltage and current value with which the device can be powered
Explanation:
A battery powered device makes use of direct current (DC) electric power from a battery, while the power normally given out at an electrical outlet comes as an alternating current (AC) electric power source.
The power cord for battery-powered device, also known as an AC/DC adapter, that allows them to be plugged into electrical outlets converts the AC electric current it obtains from the electrical outlets to DC electrical current of the appropriate voltage and amperage that the device can make use of for electric power to function and for charging the battery which is the power source for the device
Therefore, the change that has to take place in the power cord is the conversion of the electric outlet alternating current (AC) voltage and amperage values, into direct current (DC) of the required voltage and current for the device

When a star is undergoing nuclear fusion what type of radiation will be found?
Answer:
I think the correct answer would be the third option. As the elements around the star begins to emit more and more electromagnetic radiation, the rocky materials are pulled in by the electromagnetic radiation. They are being drawn closer to the star and there would be a very high chance of a nuclear

4.00 kg glass coffee cup is 30.0°C at room temperature. It is then plunged into hot dishwater at a temperature of 90.0°C, as shown in Figure below. If the temperature of the cup reaches that of the dishwater, how much heat does the cup absorb? C glass = 837 (J/kg.C)*
Answer:
Q = 200800 Joules.
Explanation:
Given the following data;
Mass = 4kg
Initial temperature = 30.0°C
Final temperature = 90.0°C
Specific heat capacity of glass = 837 J/kg°C
To find the quantity of heat absorbed;
Heat capacity is given by the formula;
[tex] Q = mcdt[/tex]
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of water.
dt represents the change in temperature.
dt = T2 - T1
dt = 90 - 30
dt = 60°C
Substituting the values into the equation, we have;
[tex] Q = 4*837*60[/tex]
Q = 200800 Joules.
Therefore, the amount of heat absorbed is 200800 Joules.

ay wants to buy a new fireplace insert that will burn gas instead of wood. She normally uses two cords of wood in the winter. Wood costs $250/cord. She is interested in knowing how much she will save if she burns gas in the fireplace insert. Gas costs $0.91 per therm. One therm is 100,000 BTU. The fireplace insert burns 33,000 BTU per hour. Kay figures she will burn the fireplace 5 hours per day for 120 days. How much will she save in one winter if she burns gas instead of wood
Answer:
Saved Money = $ 319.82
Explanation:
First, we will calculate the cost of wood:
[tex]Wood\ Cost = (No.\ of\ Cords)(Unit\ Cost)\\Wood\ Cost = (2 cords)(\$ 250/cord)\\Wood\ Cost = \$ 500\\[/tex]
Now, we calculate the time to burn gas:
[tex]Time\ to\ burn\ gas = (5\ hours/day)(120\ days)\\Time\ to\ burn\ gas = 600\ hr\\[/tex]
Now, we calculate the energy:
[tex]Energy\ Required = (600\ hr)(33000\ BTU/hr)(\frac{1\ therm}{100000\ BTU})\\\\Energy\ Required = 198\ therm\\[/tex]
Now, we will calculate the cost of gas:
[tex]Gas\ Cost = (Energy\ Required)(Unit\ Cost)\\Gas\ Cost = (198\ therm)(\$\ 0.91/therm)\\Gas\ Cost = \$\ 180.18\\[/tex]
Now, we will calculate the amount of money saved:
[tex]Saved\ Money = Wood\ Cost - Gas\ Cost\\Saved\ Money = \$\ 500 - \$\ 180.18\\[/tex]
Saved Money = $ 319.82

What type of motion does this diagram represent? *
Answer:
object at rest
Explanation:
Stephen Strasburg throws out the opening pitch at Nationals Park. The ball starts at rest, but
accelerates to 42 m/s (approximately 95 mph) in the 0.02 seconds it takes to throw. If the ball
has a mass of 0.145 kg, how much force did Strasburg throw with?
Answer:
Force = 304.5 Newton
Explanation:
Given the following data;
Initial velocity, u = 0m/s (since it started from rest).
Final velocity, v = 42m/s
Time, t = 0.02 secs
Mass = 0.145 kg
To find the force;
First of all, we would have to determine the acceleration of the ball;
Acceleration = (v - u)/t
Acceleration = (42 - 0)/0.02
Acceleration = 42/0.02
Acceleration = 2100 m/s²
Now, we solve for the force;
Force = mass * acceleration
Force = 0.145 * 2100
Force = 304.5 Newton
What's the Genotype for these? If your answer is something off-topic I ShAlL rEpOrT iT u.U
Pick any free letter for each trait. For example, "A" for the dominant allele and "a" for the recessive allele for the number of arms. Assuming complete dominance, the genotype for the dominant trait will always have at least one "capital" allele, so a creature with 2 arms would have genotype either AA (homzygous dominant) or Aa (heterozygous), while a creature with the recessive trait of having 4 arms will always be homzygous recessive with genotype aa.
5. Relationships in a community can be cooperative or competitive.
True
False
Answer:
True
Explanation:
is the correct answer
Answer:
This is True
Explanation:
Communities cooperate by simply co-existing and working together to benefit the community and offering their goods and services. Some programs in a community offer social work, like volunteering and charities, which help people in need in a community.
They can also be competitive because there are lots of the same goods and services offered throughout the city, so businesses have to compete for sales to attract consumers in the communities.

on a distant planet a freely falling object has an acceleration of 20 m/s.^2 what speed will a body dropped from rest on his planet avquire in 1.5s
Answer:
30 m/s
Explanation:
Vf = ?
Vi = 0 m/s
a = 20 m/s^2
t = 1.5 s
Plug those values into the equation: Vf = Vi + at
Vf = 0 + (20)(1.5)
Vf = 30 m/s
