why does a heater having low resistance heating coils get heated more?
Answer:
Explanation:
That electrical energy will be dissipated in the form of heat, heating up the wire in the process. This heating is called Joule heating (James Prescott Joule) or ohmic heating or resistive heating. Which tells us that lower resistance (R) will produce higher current. Therefore lower resistance produces more heat.

The fact that all living things are composed of cells—which are regarded as the foundation of life—is what first distinguishes them from other types of organisms. The remarkable thing about cells is that, despite their small size, they can join together to build extremely vast structures.
Multicellular organisms are extraordinarily sophisticated creatures with amazing cellular organization. This organization starts deep within your DNA and reaches all the way up to you as an individual.

A high fountain of water is located at the center of a circular pool. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 15m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55°. How high is the fountain?
Answer:
The fountain is 3.43 m high.
Explanation:
Circumference of the pool = 15 m.
C = 2[tex]\pi[/tex]r
where C is the circumference and r its radius.
r = [tex]\frac{C}{2\pi }[/tex]
= [tex]\frac{15}{2(\frac{22}{7}) }[/tex]
r = 2.3864
radius of the pool = 2.40 m
So that the height of the fountain, h, can be determined by applying trigonometric function.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 55 = [tex]\frac{h}{2.4}[/tex]
h = Tan 55 x 2.4
= 1.4282 x 2.4
= 3.4277
h = 3.43 m
The height of the fountain is 3.43 m.

In a chemical reaction,sodium sulphate and barium chloride are mixed to form barium sulphate(a precipitate)and sodium chloride. (i)What are the reactants in the above reaction? (ii)What are the products?
Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
The baseball diamond is a square with sides 27.4 m long. If the positive x-axis points from home plate to first base and the positive y-axis points from home plate to third base, find the magnitude and the direction angle of the displacement vector is a base runner who has just hit A) a double, B) a triple, and C) a home run.
Answer:
What is the magnitude of the player 's displacement? A baseball "diamond" is a square, each side of length 27.4 m, with home plate and if each length of the base is 27.4 m, and the baseball player ran to third base,Then, the baseball player is 27.4 feet away from home plate (where he started)below the horizontal.
Explanation:
the sum of vectors we were able to find the displacement of the corridor for each case
a) d = 38.75 m
b) d = 27.4 m
c) d = 0 m
given parameters
the distance of each side of the square r = 27.4mto find
the distance in three casesA) a double
B) A triple
c) A home run
The displacement is a vector for which, in addition to the module, it has a direction, so it must be taken into account for the calculations. In the exercise, set a reference system with the x-axis in the direction from Home to first base and the y-axis from home to third base.
To find the displacement we use the Pythagoras theorem
d = [tex]\sqrt{d_x^2 + d_y^2}[/tex]
if the displacements are on a single axis the addition reduces to arithmetic addition
Let's analyze the different cases:
a) hit a double
runner goes from home plate to second base
d = [tex]\sqrt{r^2+r^2}[/tex]Ra r² + r²
d = r √2
d = 27.4 √2
d = 38.75 m
b) hit a triple
Runner goes from home plate to third base
the distance from home to first base x = r
the distance from second to third base x = -r
the negative sign indicates that it is going in the opposite direction
d = [tex]\sqrt{(r-r)^2 +r^2}[/tex]
d = r
c) Hit a home run
in this case, the runner returns to the starting point, because of a vector the displacement is zero
d = 0
In conclusion, applying the sum of vectors we were able to find the displacement of the corridor for each case
a) d = 38.75 m
b) d = 27.4 m
c) d = 0

Which phase of cell division is shown?
Exploring meiosis.
A. metaphase
B. prophase
C. anaphase
D. telophase
Answer:
Anaphase
Explanation:
This is because the spindle fibres have shortened and is pulling the chromatids towards the poles of the cell. The chromatids have also separated.
The cell division which is shown in the picture is anaphase. The correct option is C.
What are the phases of meiosis?Meiosis is divided into two main phases, each with its own set of subphases:
1 Meiosis I:
a. Prophase I: This is the longest and most complex phase of meiosis. During this phase, homologous chromosomes pair up and form bivalents, and crossing over occurs between the homologous chromosomes. The nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.
b. Metaphase I: During this phase, the homologous chromosomes line up along the metaphase plate, with one chromosome from each homologous pair facing each pole of the cell.
c. Anaphase I: During this phase, the spindle fibers contract and pull the homologous chromosomes towards opposite poles of the cell.
d. Telophase I: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in two daughter cells.
2. Meiosis II:
a. Prophase II: During this phase, the nuclear envelope breaks down, and spindle fibers form from the centrioles at opposite poles of the cell.
b. Metaphase II: During this phase, the chromosomes line up along the metaphase plate, with sister chromatids facing opposite poles of the cell.
c. Anaphase II: During this phase, the spindle fibers contract and pull the sister chromatids towards opposite poles of the cell.
d. Telophase II: During this phase, the chromosomes reach the poles of the cell and the nuclear envelope reforms around each set of chromosomes. The cell then undergoes cytokinesis, resulting in four haploid daughter cells.
Meiosis involves two rounds of chromosome segregation, resulting in four haploid daughter cells that are genetically distinct from the parent cell.
Therefore, The correct option is C i.e anaphase.

que 2. Why do we keep frequency constant instead of keeping vibrating length constam second law of vibrating string?
Answer:
The second law of a vibrating string states that for a transverse vibration in a stretched string, the frequency is directly proportional to the square root of the string's tension, when the vibrating string's mass per unit length and the vibrating length are kept constant
The law can be expressed mathematically as follows;
[tex]f = \dfrac{1}{2\cdot l} \cdot \sqrt{\dfrac{T}{m} }[/tex]
The second law of the vibrating string can be verified directly, however, the third law of the vibrating string states that frequency is inversely proportional to the square root of the mass per unit length cannot be directly verified due to the lack of continuous variation in both the frequency, 'f', and the mass, 'm', simultaneously
Therefore, the law is verified indirectly, by rearranging the above equation as follows;
[tex]m = \dfrac{1}{ l^2} \cdot \dfrac{T}{4\cdot f^2} }[/tex]

what happens to balloon filled with air when it goes very high attitude from surface of earth why
Answer:
The balloon will continue to expand and eventually burst.
Explanation:
Simply, the reason for this is because the density of the atmosphere decreases gradually as you increase in altitude closer to space. This means that the air on the outside of the balloon can't provide enough pressure over the surface of the balloon in order to counteract the gas on the inside of the balloon from expanding.
