A tugboat is pulling a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat.
Available options are:
A. –4500 N
B. –2500 N
C. 2500 N
D. 4500 N
Answer:
-4500 N
Explanation:
Given that we have F₁ = 3000N? (force of the barge)
the force of the tugboat is F '
To pull the barge, the force of the tugboat must be greater than or equal to the force of the barge.
Hence, according to Newton's third law which states that for every action or force in nature, there is an opposite reaction.
Therefore considering the available option the correct answer is "- 4500N, " this is because it is greater than the force of the barge and it's in opposition to the force exerted.
Answer:
The answer is -4500 N

Speed = Distance Time Velocity = 1. Find the velocity of a truck that travels 75miles north in 2.5 hours? List: Equation: Substitution: Answer with units:
Answer:
187.5 m/s (i think)
Explanation:
If you use the formula V= T times displacement you can find this out by doing the following-
Displacement equals 75 m
T equals 2.5 hrs
75x2.5= 187.5
and since velocity is measured in m/s, it becomes
187.5 m/s

The law of conservation of energy states:
Energy increases exponentially with time
Total energy decreases due to energy output.
Energy cannot be created or destroyed.
Energy always remains in the same form.
Answer:
Energy cannot be created or destroyed.
Explanation:
its in the name, law of "conservation" of energy. energy can only change forms not be destroyed
Answer: Energy cannot be created or destroyed.
Explanation: The law of conservation of energy states that energy can neither be created nor be destroyed due to energy loss. It can only change its states from one energy state to another.
The efficiency is defined as the ratio of output work to the input work. The efficiency of the fan is not 100%. Because some of the energy is lost in the form of heat and sound. No machine is 100% efficient. There is always some loss of energy takes place.

What will happen when two neutral objects are rubbed together?
Answer:
I hope this will help you
Explanation:
When two neutral objects come into contact--especially in a dry environment--electrons can be knocked loose from one object and picked up by the other. The object that gains electrons becomes negatively charged, while the object that loses electrons becomes positively charged. Objects with like charges repel each other, while those with opposite charges attract each other. This phenomenon--in which objects acquire an electric charge and exert a force on one another--is what we call static electricity.

Explanation:
Dietary fiber contains an indigestible material known as cellulite. This is false statement.
What is Dietary fiber?Plant substances that are not broken down by human digestive enzymes are referred to as dietary fiber.
Only lignin and a few polysaccharides were recognized as meeting this criterion in the late 20th century, but resistant starch and oligosaccharides were listed as dietary fiber components in the early 21st century.
The phrase "all polysaccharides and lignin, which are not digested by the endogenous secretion of the human digestive tract" is commonly used to define dietary fiber.
At the moment, the majority of animal nutritionists either use a physiological definition, which states that "dietary components resistant to breakdown by mammalian enzymes," or a chemical definition, which states that "the sum of non-starch polysaccharides (NSP) and lignin."

The current in the wires of a circuit is 60.0 milliAmps. If the
voltage impressed across the ends of the circuit were
doubled and the resistance were tripled, then its new current
would be ___ milliAmps.
Answer:
I' = 40 mA
Explanation:
Given that,
The current in the wires of a circuit is 60.0 mA.
If the voltage impressed across the ends of the circuit were doubled and the resistance were tripled such that,
V' = 2V and R'=3R
The relation between current, voltage and resistance is given by :
V = IR
Let I' be the new current. So,
V'=I'R'
⇒ [tex]I'=\dfrac{V'}{R'}\\\\I'=\dfrac{2V}{3R}\\\\I'=\dfrac{2}{3}\times \dfrac{V}{R}\\\\I'=\dfrac{2}{3}\times I\\\\I'=\dfrac{2}{3}\times 60\\\\I'=40\ mA[/tex]
So, the new current would be 40 mA.

Answer:
Option C. 83.8 J
Explanation:
From the question given above, the following data were obtained:
Mass (m) of object = 2 Kg
Velocity (v) of the object = 5 m/s
Height (h) = 3 m
Mechanical energy =.?
Next, we shall determine the kinetic energy of the object. This can be obtained as shown below:
Mass (m) of object = 2 Kg
Velocity (v) of the object = 5 m/s
Kinetic energy (KE) =?
KE = ½mv²
KE = ½ × 2 × 5²
KE = 1 × 25
KE = 25 J
Next, we shall determine the potential energy of the object. This can be obtained as shown below:
Mass (m) of object = 2 Kg
Height (h) = 3 m
Acceleration due to gravity (g) = 9.8 m/s²
Potential energy (PE) =.?
PE = mgh
PE = 2 × 9.8 × 3
PE = 58.8 J
Finally, we shall determine the mechanical energy of the object. This can be obtained as shown below:
Kinetic energy (KE) = 25 J
Potential energy (PE) = 58.8 J
Mechanical energy =?
Mechanical energy = KE + PE
Mechanical energy = 25 + 58.8
Mechanical energy = 83.8 J
