Explanation:
List Known Values-
35N
4M
Formula-
W=FJ
Substitution-
W= 3.5N (4m)
Answer & Units-
140 N
Bobby perform in pushing a 35 N crate a distance of 4 meters the work done by him is 140 joules per second.
What is work?The work is something which need energy to be done it can be any physical or chemical energy that can be calculated with the help of Newton law.
Work is calculated by multiplying the force required for the work by the amount of movement of substance or object.
W = F × d here, W = work
F = force
d = distance
Substituting the value in the formula,
W = 35 × 4
W = 140 joules
Newton-meter is the same thing as a joule so the unit is joules.
Therefore, bobby perform in pushing a 35 N crate a distance of 4 meters the work done by him is 140 joules per second.

How much energy is required to raise the temperature of 3 kg of iron from 20°
C to 25°C? Use the table below and this equation: Q = mcAT.
Answer:
The correct option is (c).
Explanation:
Given that,
Mass of iron, m = 3 kg = 3000 g
The temperature of ice increases from 20° C to 25°C.
The specific heat of iron is 0.45 J/g°C
We need to find the energy required to raise the temperature. The formula is given by :
[tex]Q=mc\Delta T\\\\Q=3000\times 0.45\times (25-20)\\\\Q=6750\ J[/tex]
So, 6750 J of energy is required to raise the temperature or iron.

Laura jala un trineo una distancia de 2000 cm usando una cuerda, con una tensión constante de 80 N. La tarea requiere de 800 J de trabajo, ¿qué ángulo forma la cuerda con el suelo?
Respuesta:
60°
Explicación:
Paso 1: Información dada
Distancia recorrida (d): 2000 cmFuerza aplicada (F): 80 NTrabajo realizado (W): 800 JPaso 2: Convertir "d" a metros
Usaremos el factor de conversión 1 m = 100 cm.
2000 cm × 1 m/100 cm = 20 m
Paso 3: Calcular el ángulo entre la cuerda y el suelo (θ)
W = F × d × cosθ
800 J = 80 N × 20 m × cosθ
θ = 60°
Ben has a snack with a combination of raisins, chocolate pieces, and nuts. As he eats the snack, Ben picks out all of the raisins.Which BESTdescribes the snack Ben is eating
Answer:
Trail Mix
Explanation:
The best description for the snack that Ben is eating would be Trail Mix. This is a very common snack for hikers, hence the name, since it is very healthy and great for taking on hikes since it does not get affected by the sun. This snack was originally called GORP which stands for "good old raisins and peanuts" because the snack originally contained only raisins and peanuts. It has since changed to include various different ingredients such as a variety of nuts, chocolate pieces, dried fruit, cereal etc.
A list of changes is shown.
Temperature decreases
Intermolecular bonds become weaker
Freezing
Intermolecular bonds become stronger
Evaporation
Temperature increases
Vibration of molecules slows down
Molecules vibrate faster
Which of the above changes would be accompanied by an increase of the kinetic energy of particles in a liquid?
A, B, C, and H
A, C, D, and G
B, E, F, and H
B, C, F, and G
Answer:
b,c,f,g
Explanation:
it makes the most sense plus i just took the test <3 good luck
With an increase in the kinetic energy of the solid molecule the intermolecular bonds become weaker, temperature increases, melting and molecules vibrating faster are changes.
What is the effect of the increased kinetic energy?Kinetic energy is the form of the energy that is present in an entity in motion. When the kinetic energy is increased then the temperature of the particles increases and leads to evaporation.
The increased kinetic energy weakens the intermolecular bonds of the liquid particles and the molecules of the particles start vibrating fast.
Therefore, option b. intermolecular bonds become weak, option e. evaporation, option f. temperature increases and option h. molecules vibrate faster are the changes.

How are the four kinds of DNA nucleotides different from each other?
Answer:
The sugar in DNA is deoxyribose. ... Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. There are two groups of bases: Pyrimidines: Cytosine and Thymine each have a single six-member ring.
Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.
What are nucleotides ?Nucleotides are organic compounds made up of a phosphate and a nucleoside. They function as monomeric units of the deoxyribonucleic acid and ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth.
Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA. The four nucleotides have different base structures, but they are all composed of a nitrogenous base, a deoxyribose sugar, and a phosphate group.
The quantity of phosphate residues that a nucleotide has determined its name. Adenosine triphosphate, for instance, is the name of a nucleotide that consists of an adenine base and three phosphate residues (ATP). Adenosine diphosphate would be the nucleotide if it has two phosphates (ADP).
Thus, Adenine, Cytosine, Thymine, and Guanine are the four nucleotides that make up DNA.
