Answer:
Causes. Wasting can be caused by an extremely low energy intake (e.g., caused by famine), nutrient losses due to infection, or a combination of low intake and high loss. Infections and conditions associated with wasting include tuberculosis, chronic diarrhea, AIDS, and superior mesenteric artery syndrome
A machine has mechanical advantage,what does it mean?
Answer:
In machines that transmit only mechanical energy, the ratio of the force exerted by the machine to the force applied to the machine is known as mechanical advantage. Under mechanical advantage the distance the load will be moved will be only be a fraction of the distance through which the effort is applied.

kinematics is just the focus on motion of an object rather than other factors such as what caused it. Seeing and studying how a apple moves without studying what force pushed the aple in the first place.
A constant force acts on a body causing the momentum of the body
to increase. Which expression relates the force to the momentum and the time taken?
The expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].
Let the constant force causing change in momentum, = FLet the time of force action = t
The impulse experienced by the body at the given constant force and time is calculated as follows;
[tex]J = \Delta P = mv[/tex]
where;
ΔP is change in momentum
The force acting on a body is given by Newton's second law of motion;
[tex]F = ma\\\\F = \frac{mv}{t} \\\\Ft = mv\\\\Ft = \Delta P\\\\F = \frac{\Delta P}{t}[/tex]
Thus, the expression that relates the force to the momentum and the time taken is [tex]F =\frac{\Delta P}{t}[/tex].

Calculate the molecular weight of Aluminium hydroxide
Al(OH)3 = 26.98 + [(16×3) + (1.01×3)] = 26.98 + 51.03 = 78.01 and the unit will be g/mol
Al(OH)3 = 78.01 g/mol1. Define friction, and explain why it occurs.
Answer:
The simplest way to put it is that friction is a force in which there is a resistance between material elements when they slide against each other. There is no completely accurate answer as to why friction occurs, but scientists believe that it is because of tiny bumps on the surface of a material.

A student doing an experiment spilled some salt and sugar into the sink. How should these substances be cleaned up?
Answer:
I guess rinse it out and wipe it up. It's not a hazardous substance so there's nothing to worry about.
These substances should be cleaned up rinsing the area or removing the compounds with a cloth and dispose of it in the trash.
Sugar is a chemical compound also called sucrose. Its chemical formula is C12H22O11. This compound is normally used to sweeten foods.
On the other hand, common salt is a chemical compound. Its chemical formula is NaCl. This compound is normally used to give food a salty taste.
According to the above, in which a student spilled some salt and sugar in the sink and does not know how to clean it, it can be concluded that the proper way to clean these chemical compounds is by rinsing the area or removing the compounds with a cloth and dispose of it in the trash because neither of them represents biological, chemical or physical risks and a specialized treatment is not required for them.

A car start from rest and reached with a speed of 20m/s in 9seconds calculate the acceleration of the car and calculate the displacement covered in this time
Hi there!
Acceleration:
a = Δv / Δt, so:
a = 20/9 ≈ 2.22 m/s²
Displacement:
We can use the equation Δd = v₀t + 1/2at² to solve. (Initial velocity is 0).
Δd = 1/2at²
Plug in the acceleration and time:
Δd = 1/2(2.22)(9)² ≈ 89.91 m

how energy from food can be used to make a flashlight shine?
Answer:
a toaster
Explanation:
Energy from food can be used to make a flashlight shine by converting it into electrical energy.
When we eat food, our bodies break down the food into glucose. Glucose is a type of sugar that our bodies can use for energy. When glucose is broken down, it releases energy. This energy is used to power our cells and to do work.
One of the things that our bodies can do with energy is to convert it into electrical energy. This electrical energy can be used to power devices, such as flashlights. In a flashlight, the electrical energy from food is converted into light by a process called incandescent lighting. Incandescent lighting works by heating a filament until it glows. The filament is made of a material that gives off light when it is heated.
The electrical energy that powers the filament comes from a battery. The battery is charged by the energy from food. When we turn on the flashlight, the battery sends electrical energy to the filament. The filament heats up and glows, creating light.
