What resistance does a 25 W light bulb have if 12.6 V is applied to it?
(3 marks)
Answer:
Explanation:
W = 25 Watts
V = 12.6 Volts
I = ? I is the current in amperes.
Solution
25 = 12.6 * I
I = 25 / 12.6
I = 1.98 amperes
V = 12.6
I = 1.98
R = ??
V = I * R
12.6 = 1.98 * R
R = 12.6 / 1.98
R = 6.35 ohms

How did Lavoisier's study of combustion prove that fire was not an element?
Answer:
In June 1783, Lavoisier reacted oxygen with inflammable air, obtaining "water in a very pure state." He correctly concluded that water was not an element.
Explanation:
As the fire left behind ashes of a substance it indicated that it is not an element as element cannot be decomposed in to simpler substances.
What is an element?It is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.
Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.
The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

Be affectionate. Most girls love getting showered with affection and compliments from a guy they care about. Some girls can be insecure, and love being reassured a lot. To be affectionate, just give her a gentle touch, put your arm around her, hold her hand, or do whatever you can do to give her a little bit of physical touch. This doesn't mean you have to use everything you have on her, pick the right moments to let her know you care and it'll mean a lot more than having your arm around her for four hours.DO YOU KNOW SHE LIKE YOU?Look for open body language. When a girl likes you, she will face in your direction. If a girl has her torso turned towards you in an open manner, this means that she is confident talking with you. If she has a closed body position, namely crossed arms or legs, she may be shy or nervous to talk to you or she may simply be creating a barrier to signal that she is uninterested.[1]When she is sitting with her legs crossed, watch her feet. If they are pointed towards you, it might mean that she likes you and wants to get closer to you.[2]Generally speaking, a girl will stand closer to you and will have more relaxed body language if she feels comfortable around you — for example, she'll have relaxed shoulders and she won't cross her arms, But, everyone's personality and cultural upbringing are different, so don't take it as a sign she's not into you if this isn't the case.[3]Liam está empujando una caja pesada por una rampa a una velocidad constante.

 is Marissa's car initial velocity
 is Marissa's car constant acceleration (assuming this is the acceleration, since 1269 m/s^{2} does not make sense)

what is the average acceleration of a car that is initially at rest at a stop light and then accelerates to 24 m/s in 9.4 s?
Answer:
Below
Explanation:
To find the acceleration of the car you can use this formula :
vf = vi + at OR a = v/t
I'm going to use the first one because it explains the steps more clearly :
vf = 24 m/s
vi = 0 m/s
t = 9.4 s
a = ?
24m/s = 0 + (a)(9.4s)
24m/s = a9.4
Divide both sides by 9.4
a = 2.55319 m/s^2
Round to 3 sig figs
a = 2.6 m/s^2
Hope this helps! Best of luck <3

Answer:
Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method. Often taught in chemistry or other science classes, this method is known for its simplicity and accuracy.
Explanation:
Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.
What is displacement?Shortest distance between two point are called as displacement, or we can say that when a body moves between two points the total lengths between two points are called as distance but the shortest distance between two point is called as displacement. Displacement is measured in meter and it is a vector quantity. Displacement may became zero but distance never became zero.
In above problem we cam say that in a race car start form a point and reaches at the same point then it's displacement is zero because there is no shortest distance. Displacement is measured in meter and it is a vector quantity. Displacement may became zero but distance never became zero.
Therefore,Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.

The resultant of the four forces on the balloon is 1,212.35 N at 62⁰.
The given parameters;
Force applied to the north = 5120 NForce applied to the west = 1520 NForce applied to the east = 950 NForce applied to the south = 4050 NThe resultant vertical force is calculated as follows;
[tex]F_y = 5120 \ N - 4050 \ N\\\\F_y = 1,070 \ N[/tex]
The resultant horizontal force is calculated as follows;
[tex]F_x = 1520 \ N - \ 950 \ N\\\\F_x = 570 \ N[/tex]
The resultant of the four forces is calculated as follows;
[tex]F = \sqrt{F_y^2 + F_x^2} \\\\F = \sqrt{(1,070)^2 + (570)^2} \\\\F = 1,212.35 \ N[/tex]
The direction of the force is calculated as follows;
[tex]\theta = tan^{-1} (\frac{1070}{570} )\\\\\theta = 62^0[/tex]
Thus, the resultant of the four forces on the balloon is 1,212.35 N at 62⁰.

A raindrop was 16meters above the ground, falling straight down at a constant velocity. It took the raindrop 2seconds to fall half the distance to the ground. What was the raindrop's velocity?
what is the answer
Answer is 4 m/s
Step-by-step explanation:-Let :-
Constant velocity = v
Time (t) = 2 seconds
Height (h) = 16 metres
As the raindrop has constant velocity, we can write that :
[tex] \frac{h}{2} = vt[/tex]
Substituting the values, we get,
[tex] \frac{16}{2} = v \times 2[/tex]
[tex]8 = v \times 2[/tex]
[tex] \frac{8}{2} = v[/tex]
[tex]v = 4 \: m/s[/tex]
Therefore, the velocity of the raindrop is 4 m/s.
