The net force needed to accelerate a 200 kg piano is 50N

According to Newton's law of motion, the formula for the net force is calculated as:

∑F = ma

Given the following parameters

Mass = 200kg

acceleration = 0.25m/s²

Substitute the given parameters into the formula

∑F = 200 * 0.25

∑F = 50N

Hence the net force needed to accelerate a 200 kg piano is 50N

Which type of stress is a uniform stress that doesn't lead to earthquakes?

ElenaW [278]

Answer:

C) Lithostatic pressure

Explanation:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.

In the Earth the pressure due to the weight of overlying rocks is a uniform stress and is referred to as confiningstress. If stress is not equal from all directions then the stress is a differential stress. Three kinds of differential stress occur. Shear stress, which result in slippage and translation.

The "Garbage Project" at the University of Arizona reports that the amount of paper discarded by households per week is normally

Lorico [155]

Answer:

54%

Explanation:

We are given that

S.D=4.2 lb

Mean= $\mu=9.4 lb$

We have to find the percentage of household throw out at least 9 lb of paper a week.

Normal distribution formula :

$P(X\geq a)=P(z\geq \frac{a-\mu}{\sigma})$

We have a=9

$P(X\geq 9)=P(z\geq \frac{9-9.4}{4.2})=P(z\geq -0.1)$

$P(X\geq 9)=1-P(z$

$P(X\geq 9)=1-0.4602=0.5398\times 100=54$ %

Hence, the percentage of household throw out at least of paper a week=54%

Identify the solute and solvent in a solution made of 15g of oxygen and 5g<br> of helium

Marrrta [24]

Taking into account the definition of solvent and solute, helium is the solute and oxygen is the solvent.

<h3>Definition of solute and solvent</h3>

The solution is a homogeneous mixture of two or more components that have the same chemical and physical properties in a single phase. A solution is made up of two main components: the solute and the solvent.

That is, the solute and the solvent are the components of a chemical solution, that is, of a homogeneous mixture that occurs when one or more substances are dissolved in another substance.

The solute is the substance that dissolves in a solution. In solution, the solute is usually found in a lower proportion than the solvent.

Solvent is the substance in which a solute dissolves, resulting in a chemical solution. Generally, the solvent is the component that is found in the highest proportion in the solution. It will always be the solvent who will determine the state of the matter that will have the solution.

<h3>Solute ans solvent in this case</h3>

In this case, you consider that the solute is the component in less quantity and the solvent is the major component.

You know that a solution made of 15 g of oxygen and 5 g of helium. Then, helium is the solute and oxygen is the solvent.

Simone created a chart to summarize the energy transformations that take place when energy from the wind is used to generate ele

sattari [20]

Wind power is produced from the wind turbines or sails that uses air flow to convert it into mechanical power. It is an alternative to fossil fuel burning, it is all around, renewable, clean, produces no greenhouse gases and uses little land. The advantages of wind power have been greatly praised by many. However, it has disadvantages. Wind power especially at farm is noisy and may spoil the view for their neighboring people. Also the amount of electricity depends on the strength of the wind. If no wind is around, no electricity is produced.
