Answer:
To be honest, if you’re preparing for your IGCSEs, you should really know how to use a ruler, but I’ll explain it anyway.
A ruler is a flat object, usually rectangular, with markings along one or more of its straight edges.
These markings show us how long something is. It can only be used to measure other straight lines. If you want to measure something, hold the ruler against it, aligning the start of the edge of the object with the 0 on the ruler, and read off the ruler how long it is.
Explanation:
The volume of the cylinder can be found by putting the value of length and height in the formula πr²l. Length can be measured by using a ruler.
What is volume?
An object's volume is a measurement of the amount of space it occupies in three dimensions. This indicates that an elephant's volume is more than a mosquito's volume.
Since gases fill their containers to the brim, their volume is equal to the container's internal capacity. Liquids are routinely measured using containers with specified internal shapes or ones with predetermined volumes.
A ruler is a flat device with marks along one or more of its straight edges. It is typically rectangular.
The length of anything is indicated by these markers. Only other straight lines can be measured using it. If you want to measure something, place the ruler against it, line up the object's beginning edge with the number 0, and then read the length of the ruler.

which particle will be deflected toward the positive plate as it enters the electric field
Answer:
Electrons are negatively charged and are deflected on a curving path towards the positive plate. Neutrons have no charge, and continue on in a straight line.
The particle will be deflected toward the positive plate as it enters the electric field is an electron.
What is an Electric field?The electric field is the region of space in which the particle experiences the electrostatic force.
As the plate is positive, so to deflect any particle towards it, the particle must be negatively charged.
An electron is a particle that has a negative charge.
The particle will be deflected toward the positive plate as it enters the electric field.

500cm3 of water is to be jeated from room temperature 28oc to 100oc in order to prepare ahot cup pf coffee. What os the minimum heat required
Answer:
The minimum heat required is 171626 joules.
Explanation:
By First Law of Thermodynamics, the amount of heat ([tex]Q[/tex]), in joules, is equal to the change in internal energy of water. The minimum heat required is the sensible heat necessary to heat up the water. That is:
[tex]Q = \rho\cdot V \cdot c\cdot \Delta T[/tex] (1)
Where:
[tex]\rho[/tex] - Density of water, in kilograms per cubic meter.
[tex]V[/tex] - Volume of water, in cubic meters.
[tex]c[/tex] - Specific heat of water, in joules per kilogram-degree Celsius.
[tex]\Delta T[/tex] - Change in temperature, in degrees Celsius.
If we know that [tex]\rho = 1000\,\frac{kg}{m^{3}}[/tex], [tex]V = 5\times 10^{-4}\,m^{3}[/tex], [tex]c = 4186\,\frac{J}{kg\cdot ^{\circ}C}[/tex] and [tex]\Delta T = 82\,^{\circ}C[/tex], then the minimum heat required is:
[tex]Q = 171626\,J[/tex]
The minimum heat required is 171626 joules.

ignoring friction, what is the mass of an object accelerating at 1.8m/s2 to which an unbalanced force of 42 Newtons has been applied?
Explanation:
Newton's second law:
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.
What is force?A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given in the question the mass of an object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied is ,
Using Newton's second law force is given as
F = ma
42 N = m (1.8 m/s²)
m = 23 kg
An object accelerating at 1.8 m/s² to which an unbalanced force of 42 Newtons has been applied, mass of object is 23 kg.

Experiments have shown that a magnetic Just sitting next to a wire produced no current flow through that wire. However, If the magnet is____________ then a current is Induced the wire. The_____________ the magnet moves, the______________ the Induced current.
Answer:
Experiments have shown that a magnetic Just sitting next to a wire produced no current flow through that wire. However, If the magnet is brought close to the coil of wire or a relative motion is established between the magnet and the wire then a current is induced in the wire. The closer the magnet moves, the more the Induced current.
Explanation:
A magnet sitting next to a wire would not induce a current in the wire because the magnetic lines of force of the magnet are not in relative motion to the wire.
If you move a magnet close to a wire, the electrons will move thus generating current.

Write down three facts you about motion
Write Them in complete sentences
Answer:
Kindly check explanation
Explanation:
Motion of an object could be explainwd as how a body changes position over time. Some of the proven facts about motion are stated by Sor Isaac Newton, named the Laws of motion :
1. A body will continue on it's state of rest or uniform motion in a straight line unless acted upon by a force to make it act otherwise.
2.) The second law explains that the force acting in an object is a product of the mass and acceleration.
Force = mass * acceleration due to gravity
3.) To every action, there is an equal and opposite reaction.
That is ; applied force in the positive direction on an object, yield an equal amount of force in the opposite direction.
The crane pull up the mass with 1150 N. Find the acceleration the
mass.m = 100kg
Kren tersebut menarik naik jisim itu dengan 1150 N. Cari daya
paduan pada jisim itu
[use gravitational acceleration, g = 9.81 m s?]
Answer:
-1.69 m/s²
Explanation:
We are told the crane pulls up the mass with a force of 1150 N.
This means it is in an opposite direction to gravity and thus acceleration(a) is negative.
Now, the gravity is acting downwards, thus, total force is;
F = mg - ma
1150 = 100(9.81 - a)
Divide both sides by 100 to get;
11.5 = 9.81 - a
a = 9.81 - 11.5
a = -1.69 m/s²

⦁ A body has weight 10 N. How much force is required to move it vertically upward with an acceleration of 3 ms-2?
Answer:
Force = 3.06 Newton.
Explanation:
Given the following data;
Weight = 10N
Acceleration = 3m/s²
To find the force required;
First of all, we would determine the mass of the body.
Weight = mass * acceleration due to gravity
We know that acceleration due to gravity is equal to 9.8m/s².
10 = mass * 9.8
Mass = 10/9.8
Mass = 1.02 kg
Now, we can find the force required by using the formula below;
Force = mass * acceleration
Force = 1.02 * 3
Force = 3.06 Newton.

You swing your golf club such that it hits a ball with a force of 15 newtons. It makes contact with the ball for a distance of 0.01 m. What is the work on the ball?
Answer:
W = 0.15 J
Explanation:
Given that,
The force acting on the ball, F = 15 N
It makes contact with the ball for a distance of 0.01 m
We need to find the work done on the ball. The work done can be calculated as :
W = Fd
So,
W = (15 × 0.01) J
W = 0.15 J
So, the work done is 0.15 J.

top hat- reflect
elepahnt- i think absorb im quite sure
Explanation:
Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. Different shirts with different colors will absorb light of different wavelength. Black shirt will absorb all colors of light while white shirt will reflect all colors of light. thats why on a hot day you wouldnt want to wear a black t shirt.
