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 gravitational pull of the Moon is responsible for visible changes on the surface of Earth. Which of the following is caused by the pull of the Moon's
gravity?
1: Change of seasons
2: Movement of clouds
3: High and low tides
4: Building of mountains
Answer:
3: High and low tides
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Additionally, they are caused by the cycle of rising and falling ocean water that are repeated approximately every 12.5 hours.
In conclusion, the gravitational pull of the Moon is responsible for visible changes on the surface of Earth. Thus, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.

Velocity is a time-dependent property of an object, while acceleration is not.
A vibrating object with a high frequency would be
described as having a low period.
True or false
Answer:
False
Explanation:
It would be described as having a long period
A vibrating object with a high frequency would be
described as having a low period is a false statement.
The individual air molecules do not "travel" with the wave. They just vibrate back and forth. When the vibrations are fast (high frequency), you hear a high note. When vibrations are slower, you hear a lower note.
What is frequency ?"Frequency is the number of occurrences of a repeating event per unit of time. "It is also occasionally referred to as temporal frequency to emphasise the contrast to spatial frequency, and ordinary frequency to emphasise the contrast to angular frequency.
Other units: cycles per second (cps); revolutions
SI unit: hertz (Hz)
In SI base units: s−1
Derivations from other quantities: f = 1 / T
What is period ?"A period T is the time required for one complete cycle of vibration to pass a given point. "As the frequency of a wave increases, the period of the wave decreases. Frequency and Period are in reciprocal relationships and can be expressed mathematically as: Period equals the Total time divided by the Number of cycles.

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

tangential velocity of 0.8 m/s. If the force that maintains the child's circular
motion is 25 N, what is the mass of the child?
what is the definition of the word amplitude
Explanation:
Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
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]
From which it can be shown that the following relation holds with the limits of error in the experiment
m₁·l₁² = m₂·l₂² = m₃·l₃² = m₄·l₄² = m₅·l₅²

A ball has 17 J of kinetic energy and its mechanical is 25 J
If the ball has a mass of 3.2 KG what is it’s height above ground?
Answer:
0.255m
Explanation:
The total mechanical energy of the ball is given 25 J. The potential energy of the ball is 8 J. Then, the height of the ball above the ground is 0.25 m.
What is kinetic energy ?Kinetic energy of an object is the energy generated by virtue of its motion whereas potential energy is generated by virtue of its position at a height from the ground.
The sum of kinetic and potential energy of the object is called its mechanical energy.
given Ke of the ball = 17 J
mechanical energy = 25 J
then potential energy = 25 J - 17 J = 8 J.
We have the relation between potential energy, mass and height h as :
p = mgh .
given the mass m = 3.2 kg
g = 9.8 m/s²
then, h = p / (mg)
h = 8 J / (3.2 kg× 9.8 m/s² )
= 0.25 m.
Therefore, the height of the ball above the ground is 0.25 m.
