An object with mass m is attached to the end of a string and is raised vertically at a constant acceleration of g 6. If it has been raised a distance l from rest, how much work has been done by the tension in the string?.

Answers

Answer 1

11/10 MgL work has been done by the tension in the string. If the object has been raised a distance l from rest.

Define work done?

The definition of work is expanded so that it encompasses both the forces applied to the body and the overall displacement of the body. A constant force F is present before this block. The objective of this force is to move the body d meters in a straight line in the force's direction.

Given,

Mass of object, M

Acceleration of object, a = g/10

Distance covered vertically, L

Tension of string, T

Work done by tension in string, W

W = T × L

By applying equilibrium force on string,

T - Mg = Ma

g = gravitational acceleration

T - Mg = M (g/10)

T = M(g/10) + Mg

T = 11/10 Mg

By substituting the value in, W = T × L

W = 11/10 Mg × L

W = 11/10 MgL

∴ Work done by tension is 11/10 MgL.

To find the order of a reaction with respect to one reactant, you will monitor the choose. As the choose. Of choose. Is changed.

Answers

You must keep track of the change in reaction rate as the reactant's concentration is altered in order to determine the order of a reaction with regard to a single reactant.

How can the order of reaction be determined with regard to each reactant?

Adding together the individual orders yields the reaction's overall order. The total order is 2, for instance, if the reaction is first order with regard to both A and B (a = 1 and b = 1).

According to the rate law, the exponent raised by the concentration term for each reactant determines the order of a chemical reaction with regard to that reactant. The sum of the exponents raised for the rate law's concentration terms determines the reaction's overall order.

Most of earths volcanoes are formed by a the interaction of continental plates b the melting of ice on continental plates c meteorites that strike continental plates d water evaporating this is earth science

Answers

Most of Earth's volcanoes are formed by the interaction of continental plates.

What is earth sciences?

It is the study of the Earth's structure, properties, processes, and four and a half billion years of biotic evolution.

The movement of faults at plate boundaries can provide a convenient pathway for magma to reach surface. It helps to explain this by looking at three main types of plate boundary:

constructive boundaries (divergent): where plates are moving away from each other as new crust is created between two platesdestructive boundaries (convergent): where plates are moving towards each other and old crust is either dragged down into mantle at a subduction zone or pushed upwards to form mountain rangestransform boundaries (conservative): where plates are moving past each other and crust is neither created nor destroyed

Constructive boundaries:

At constructive plate boundaries also known as divergent boundaries, the tectonic plates move away from one another to produce volcanoes. Hot magma rises from mantle at mid-ocean ridges, pushing the plates apart

Destructive boundaries:

Volcanoes can form at subduction zones where the tectonic plates are moving towards each other and one plate descends beneath the other

Thus option a is correct answer

A 0.9295 g Sample of Cobalt Chloride Hydrate is heated until it reaches a constant mass of 0.5976 g. Assume that only water is removed. Calculate the Percent of water.

Answers

The percent of water in the cobalt chloride hydrate would be 35.71%

Percent composition

The percent composition of a component in a compound is the mass of that component relative to the mass of the entire compound. This can be mathematically expressed as:

Percent composition = mass of component/mass of compound x 100%

In order to find the percent water composition in the hydrated salt, the mass of water needs to be obtained.

Mass of the hydrated cobalt chloride sample = 0.9295 g

Mass of the cobalt chloride after removing water = 0.5976 g

Mass of water = mass of hydrated salt - mass of anhydrous salt

= 0.9295 - 0.5976

= 0.3319 g

Thus, percent water composition = 0.3319/0.9295 x 100%

= 35.71%

In other words, the percent of water in the cobalt chloride hydrate is 35.71%.

How are the transmission, prevention, and treatment of infectious diseases similar to and different from these processes in other diseases?

Answers

Answer:

Many types of medicine aim to treat a disease or injury rather than prevent it. However, preventive medicine stops the disease before it starts. Infectious diseases are transmitted from person to person by the transmission of pathogens such as bacteria, viruses, fungi or parasites. Non-communicable diseases are not transmitted by pathogens and are caused by several other indirect factors.
