Answer:
Force can also be described intuitively as a push or a pull. ... It is measured in the SI unit of newtons and represented by the symbol F. The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.

if the 50 kg objects slows down to a velocity of 1 m/s how much kinetic energy does it have?
Answer: 25
Explanation:
The kinetic energy of the object moving at the given mass and velocity is 25 J.
The given parameters;
mass of the object, m = 50 kgvelocity of the object, v = 1 m/sThe kinetic energy of the object moving at the given mass and velocity is calculated as follows;
K.E = ¹/₂mv²
K.E = ¹/₂ x 50 x 1²
K.E = 25 J
Thus, the kinetic energy of the object moving at the given mass and velocity is 25 J.

Answer:
The correct answer to the following question will be Option C (sublimation).
Explanation:
Sublimation seems to be the process in which a substance or a solid changes its sequence from solid to the gaseous without moving via the form of water.From either the framework or method, we have because the category of phase change seems to be sublimation since there is a material altered to something like the gaseous state throughout the solid.Other options aren't connected to the offer scenario. Therefore the answer to the above is the correct one.

Oliver builds a circuit connecting a light bulb to a battery with wires, leaving a gap in one of the wires. He places several objects across the gap to close the loop. He wants to see which objects allow electricity to flow and turn on the light bulb. Why do some materials allow electricity to flow through while others do not?
A. Electricity will flow if the atoms in the material are bound tightly to each other.
B. Electricity will flow if the atoms in the material are bound loosely to each other.
C. Electricity will flow if the electrons are bound tightly to their atoms in the material.
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Answer:
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Explanation:
The continuous flow of charges is known as electricity (current). The flow of these charges are due to free or mobile electron within the atoms of the conductors. The materials which will allow current to pass through them, must have free or mobile electrons which are loosely bound to their atoms.
Thus, the correction for this question is "D"
D. Electricity will flow if the electrons are bound loosely to their atoms in the material.
Diffraction of white light with a single slit produces bright lines of different colors.What is the color of the central image?
Answer:
white
Explanation:
This experiment causes lines of different colors because the constructive interference depends on the wavelength, so for different wavelength, the position of the maximum will be different.
Now, in diffraction fo a single slit we always have a central maximum (for all the colors)
This means that after the diffraction, we will have that all the colors have a maximum in the center, which will produce white light again, then the color of the central image is white
A force of 1000 Newtons is used to push a box on a flat floor. It accelerated at a rate of 5 m/s2. What is the mass of the wagon?
Answer:
67.56kg
Explanation:
Fapp+mg = ma
Fapp= applied force
mg = reactional force
g = acceleration due to gravity
Where g = 9.8m/s^2 a= 5 m/s2, Fapp= 1000N.
1000N = ma + mg
1000N = m( a+g )
1000N = m ( 5+9.8)
1000N = m×14.8
m = 1000÷14.8
m = 67.56kg.
Hence the mass of the wagon will be 67.56kg
Una caja de 5.0kg de masa se acelera desde el reposo a través del piso mediante una fuerza a una tasa de 2.0 /s2 durante 7.0s encuentre el trabajo realizado sobre la caja
Responder:
490 juliosExplicación:
Se dice que el trabajo se realiza cuando una fuerza aplicada a un objeto hace que el objeto se mueva a través de una distancia. El trabajo realizado por un cuerpo se expresa mediante la fórmula;
Workdone = Fuerza * Distancia
Como Fuerza = masa * aceleración,
Workdone = masa * aceleración * distancia
Masa dada = 5.0kg, aceleración = 2.0m / s² d =?
Para obtener d, usaremos una de las leyes del movimiento,
d = ut + 1 / 2at²
u = 0 (ya que el cuerpo acelera desde el reposo) yt = 7.0s
d = 0 + 1/2 (2) (7) ²
d = 49m
Workdone = 5 * 2 * 49
Workdone = 490 Julios

What is the critical angle for glass when the refractive index is 1.45
Answer:43.6°
Explanation:
Refractive index=n=1.45
Critical angle=c
n=1/sinc
1.45=1/sinc
Cross multiply
1.45sinc=1
Divide both sides by 1.45
(1.45sinc)/1.45=1/1.45
sinc=0.6897
c=sin(inverse)(0.6897)
c=43.6°
Critical angle is 43.6°

Growing up a tree is a conversion from light energy to chemical energy.
What is law of energy conservation?Energy can neither be created nor be destroyed , it gets only transferred from one form to another.
What is photosynthesis?The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.In simple words by the process of photosynthesis a tree makes food for itself.What happens when a tree grows?Tree makes food by absorbing the sunlight.The energy of the sunlight is used in making of ATPs in trees.ATP ( Adenosine triphosphate ) is used in various operations in trees.So, the sunlight is light energy which get converted into ATPs , which is chemical energy.
Thus, Growing up a tree is a conversion from light energy to chemical energy.

Which of the following items are NOT used to create an electric motor?
A. Magnets
B. Electric Current
C. Turbines
D. Copper Wire
Answer:
Option C, Turbines
Explanation:
An electric motor comprise of following components-
a) Magnets
b) Electric wire or solenoid
c) Motor shaft
Turbine is a component of power producing plant that is essential to rotate the shaft of the motor. Once the shaft is rotated, the electric coil placed between the magnets is also rotated. Rotating coil cut the magnetic fields to induce emf and hence electric current is produced from mechanical work (i.e rotation).
Hence, option C is correct

⦁ How much work is it to lift a 20 kg sack of potatoes vertically 6.5 m?
Answer:
work = 1275.3 J
Explanation:
work = (force)(distance)cosø ------- force = ma
=(mass*acceleration)(distance)cosø
=(20*9.81)(6.5)cos0
=1275.3J
nite that the angle of cosine is the difference between the angle of force and the distance. in this case, the force and the distance are in the same direction. :)

Ski lift carry people along 150 m cable up the side of a mountain. Riders are lifted a total of 75 m in elevation. What is the ideal mechanical advantage of the ski lift?
Ideal Mechanical Advantage (IMA) can be found by using the formula:
IMA = ID/OD
ID = Input Distance
OD = Output Distance
In the question, we are given:
ID = 150
OD = 75
Now, solve the expression with what we have.
IMA = 150/75
IMA = 2
Therefore, the IMA is 2.

A charged particle of 5.1 nC and another with 2.6 nC are separated by a distance of 5.5 m. What is the electric potential energy between the particles?
Answer:
The electric potential energy between the particles is 2.167 x 10⁻⁸ J
Explanation:
Given;
a charged particle, q₁ = 5.1 nC
another charged particle, q₂ = 2.6 nC
distance between the charged particle, r = 5.5 m
The electric potential energy between the charged particles is calculated as;
[tex]U_E = \frac{kq_1q_2}{r}[/tex]
where;
[tex]U_E[/tex] is the electric potential energy between the particles
k is coulomb's constant = 8.99 x 10⁹ Nm²/c²
Substitute the given values and solve for electric potential energy;
[tex]U_E = \frac{kq_1q_2}{r} = \frac{8.99*10^{9}*5.1*10^{-9}*2.6*10^{-9}}{5.5} \\\\U_E = 2.167 *10^{-8} \ J[/tex]
Therefore, the electric potential energy between the particles is 2.167 x 10⁻⁸ J
Em um centro de distribuição uma empilhadeira carrega uma caixa de 1000kg até o caminhão responsável pelo transporte desta carga. Partindo do repouso a empilhadeira precisa percorrer uma certa distância 8,4 m para atingir a sua velocidade máxima de operação 10 k/h. Determine a força média necessária para acelerar essa carga.
Answer:
F = 592238.09 N
Explanation:
To find the mean force you first calculate the acceleration by using the following kinematic equation:
[tex]v^2=v_o^2+2ax\\\\v_o=0m/s\\\\v=10km/h\\\\x=8.4m\\\\[/tex]
you do "a" the subject of the equation and replace the values of the other parameters:
[tex]a=\frac{v^2}{2x}=\frac{10000m/s}{2(8.4m)}=595.23\frac{m}{s^2}[/tex]
next, the force, by using the second Newton law is:
[tex]F=ma=(1000kg)(595.23\frac{m}{s^2})=595238.09\ N[/tex]
hence, the force is 592238.09 N
