Answer:
circuit breakers work in a similar way to fuses, and also protect the circuit from damage if too much current flows but work in a different way. when circuit breakers detect a surge in current in a circuit, they break the circuit by opening a switch. one type of circuit breaker used instead of a fuse and an earth wire is a Residual Current Circuit Breaker (RCCB)

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.

True or false your vocal cords act like a guitar string when it comes to sound
Answer:
True
Explanation:
Centripetal acceleration depends directly on the square of the object's speed and inversely on
the radius of the circle.
A-True
B-False
Answer:
True.
Explanation:
The formula for the centripetal acceleration of an object can be calculated by the formula as follows :
[tex]a_c=\dfrac{v^2}{r}[/tex]
Where
v is the speed of an object
r is the radius of the circle
It means, the centripetal acceleration depends directly on the square of the object's speed and inversely on the radius of the circle. Hence, the given statement is true.

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.

The attractive force between two objects that depends on their masses and the distance between them is _______?
Answer:
gravitational force
Explanation:
an object with mass attractive another object with mass
ANSWER:
GRAVITATIONAL FORCE
EXPLANATION :
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
Which best represents the reaction of calcium and zinc carbonate (ZnCO3) to form calcium carbonate (CaCO3) and zinc? Ca → ZnCO3 + CaCO3 → Zn Ca + ZnCO3 → CaCO3 + Zn CaCO3 + Zn → Ca + ZnCO3 CaCO3 + Zn + Ca → ZnCO3
Answer:
Ca + ZnCO3 → CaCO3 + Zn

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.
Two by four about a three the espn by the Xbox 360 by the one two three and the logical by the fire the iso cohedron uh the Isosceles and the diameter by the three by four?
Answer:
divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4
Explanation:
So the first few words in this statement talks about two and four being equal to around three therefore giving you "divided by 2" as you need to divide the four by 2 and add one to get 3. The next statement "the espn by the Xbox 360", espn can be deemed as a secured entity that paces around a nun therefore giving you entity_secured_pace_nun and since this is being multiplied by a box and by 360, you apply the "Improve Rule of Baseless Base". This rule allows you to get entity_secured_pace_nun_box_9. Box comes from multiplying what we have with box and the 9 comes from adding 3+6+0. Since a logical fire is present in this equation, you burn the letters in "two three" that have no protection, these letters are t,w,t,h, and r. Next, you can take cohedron that sounds like couldron and brew yourself an akward potion with the tri sided isosceles. The diameter can be seen as a round up rule that allows you to regroup the answer you have so far. The "by the three by four" can easily be translate from the "Baseless Base Rule Compilation" giving you divided by 3 and divided by 4. That is why the answer is divided by 2 plus one entity_secured_pace_nun_box 9 divided by oee burned akward potion tri tour all around divided by 3 divided by 4. No need to thank me.
