what happens to the brightness of the bulb when the resistor is increased?
Answers
Answer: As the variable resistance increases its resistance, the current which flow through the lamp will decrease and therefore its brightness decreases. ... If the resistors are very large, they have no impact and the lamps will be the same brightness.
Explanation:
Answer:
The intensity or brightness of the bulb increases as more dry cell is added in the circuit.

Vivian went on a bicycle trip through Germany with her family. One afternoon, she rode her bicycle along a long flat road at a constant speed for 24 kilometers (km). The ride took her 1.2 hours (h). At what speed did she ride her bicycle?
Answers
Answer:
20km/h
Explanation:
Given parameters:
Distance moved = 24km
Time = 1.2hrs
Unknown:
Speed of her ride = ?
Solution:
Speed is the distance covered per unit of time.
So;
Speed = [tex]\frac{distance}{time}[/tex]
Speed = [tex]\frac{24}{1.2}[/tex] = 20km/h

A wave in which the particles of the medium move up and down as the wave passes through is a transverse wave or a
a longitudinal wave
Answers
Answer:
transverse waves
Explanation:
this is because the definition of transverse waves is transverse waves are waves that travel perpendicular to the direction of the wave motion
however the definition of longitudinal waves is that longitudinal waves are waves that travel parallel to the direction of the wave motion.
so you can see the parallel means it forms compressions and rarefactions
but perpendicular means the particles will move up and down to the straight horizontal line, that's how lines are perpendicular right? ,
so the answer is transverse wave

A car advertisement states that a certain car can selerate from rest to 20 m/s in 7 seconds. Find the car's average acceleration
Answers
Answer:
2.86m/s²
Explanation:
[tex]\boxed{average \: acceleration = \frac{change \: in \: velocity}{time} }[/tex]
Car's average acceleration
[tex] = \frac{20 - 0}{7} \\ = 2.86 \: m/ {s}^{2} \: (3 \: s.f.)[/tex]
The reason why the change in velocity over time is average acceleration is because we are finding the total difference in velocity and dividing it against the total duration. This means that the acceleration of the car can vary throughout the 7 seconds (may not be a constant acceleration) but on average, the car's acceleration 2.86m/s², to 3 significant figures.
Change in velocity
= v -v₀
= final velocity -initial velocity
Since the car is at rest at the beginning, the initial velocity (v₀) is 0m/s.
Answer:
Given :-Acceleration = 20 m/sTime = 7 secTo Find :-Average acceleration
Solution :-As we are already knowing that
[tex] \sf Acceleration_{Avg} [/tex] = TA/T
TA = Total acceleration
T = Time
A = 20/7
A = 2.85 m/s²
If two forces are acting on an object , one is 25N west, and the other is 50N east. Calculate the net force.
Answers
Answer:
Explanation:
Since the forces are only in the x-direction, you could just add the two forces. The West is to the left, so it would be -25N with the negative sign indicating direction. The East is to the right, so that would be +50N.
50 + (-25) = 25N to the right or the positive i-hat direction
in what way is Speed related to Kinetic Energy?
Answers
Answer:
Explanation:
In order to find kinetic energy, you need information about the velocity. Speed is the magnitude of the velocity.
Kinetic energy is 1/2mv^2
m being mass
v being velocity
The kinetic energy of an object is directly proportional to the speed of the object. If we double the speed of the object then the kinetic energy of the object will increase by a factor of four or four times.
What is Kinetic energy?Kinetic energy is the energy which is present in an object which has because of its motion. If we want to accelerate an object, then we must apply the force of some magnitude. Applying a force, requires us to do some work. After the work has been done, then the energy has been transferred to the object, and the object will be moving with a new constant speed.
Kinetic energy is directly proportional to the mass of the object and to the square of its speed or velocity:
K.E. = 1/2 m × v²
If the mass has the units of kilograms and the velocity of meters per second, then the kinetic energy has units of kilograms-meters squared per second squared.

Use what you have learned in the reading to answer the following question. The point of a compass needle points to Earth’s north pole. The point in the compass needle has–
~the same polarity as Earth's north pole.
~the opposite polarity from Earth’s north pole.
~no polarity.
~unlimited polarity.
Answers
Good luck to you!
The point in the compass needle has the opposite polarity from Earth’s north pole. The correct option is B.
What is a compass needle?The compass needle A magnetized pointer within a compass that can freely align with the Earth's magnetic field.
The magnetic needle is the most important part of the compass. It swings around the compass as you move, but the red end always points north and the white (or sometimes black) end always points south.
If you mean the geographical North Pole, the needle would point south because that is the only way to get there; more specifically, it would point south along the 112.4 degrees west longitude meridian towards the magnetic north pole at 82 degrees north, where compasses point.
Thus, the correct option is B.

Within a few sentences, explain the difference between meiosis and mitosis.
Answers
Mitosis and meiosis are both processes which describe the production of new cells. Mitosis produces 2 daughter cells which are genetically identical to the parent cell. Each daughter cell is diploid (contains the normal number of chromosomes). This is the result of DNA replication and 1 cell division. Mitosis is used in growth and asexual reproduction. Meiosis produces 4 daughter cells, each of which are unidentical to the parent cell and to one another. Each daughter cell is haploid (contains half the number of normal chromosomes). This is the result of DNA replication, followed by crossing over of homologous chromosomes and separation of chromosomes. There are two cell divisions: the parent cell divides once and then each cell produced by this first division divides once. Meiosis is used to produce gametes (sperm and egg cells), the cells of sexual reproduction. Two gametes fuse to form a zygote, a diploid cell with the full number of chromosomes.

Explanation:
Centripetal force is the force which causes the change in direction of velocity towards the center of the circular motion of an object.
What is Centripetal Force?Centripetal force is any kind of force which causes a change in the direction of velocity of an object which is moving towards the center of the circular motion. The component of this force which is perpendicular to the velocity of the object is the part which results in the centripetal force.
The force of gravity which acts up on a satellite in the orbit is an example of a centripetal force. The friction of the tires of a car which makes a turn that is similarly provides centripetal force on the car.
