Answer:

85.14 rad/s

Explanation:

Since we know that 1 revolution is equal to 2pi rad:

813(rev)/1(min) x 2pi/1 x 1(min)/60(seconds) = 85.14 rad/s

Answer:

The amount of time that is required for the microwave to heat the coffee is 34.4 seconds.

Given the following data:

In order to determine the amount of time that is required for the microwave to heat the coffee, we would use this formula:

[tex]Energy = power \times time\\\\[/tex]

Making time the subject of formula, we have:

[tex]Time = \frac{Energy}{Power}[/tex]

Substituting the given parameters into the formula, we have;

[tex]Time = \frac{30962}{900}[/tex]

Time = 34.4 seconds.

The number of hours that the computers will be infected by a computer virus is one hour.

Viruses are known to be some forms of computer worms or trojans that can be spread through a system in a lot of ways.

Its spread can be through networks, discs, email attachments etc. It is one that gives others access to your computer.

The number v of computers infected by a computer virus is given by V(t) = 100e^(4.666t)

So therefore,  t is the time in hours.

After 1 hour the number of computer infected v(t=1) = 100*e^(4.666*1)

=100*e^4.666

Late answer, but the answer is: A the countries occupied by Germany.

Explanation:

For future people I guess

The United States, Great Britain, the Soviet Union, and France participated in a joint occupation of the German state following Germany's defeat in the Second World War. Thus, option A is correct.

In Germany's defeat in World War II, the country was jointly occupied by the continent's four major allies: the United States, Great Britain, the Soviet Union, and France.

The military overthrow of the Soviet Union; the abolition of the alleged Communist menace to Germany; and the seizing of valuable Soviet-controlled land as Lebensraum (German for “Living space”) for long-term German settlement.

During World War II, Germany's air raids posed the toughest challenges to halting its incursions into Europe. For the neighboring European nations, Adolf Hitler's military prowess and fast-moving ground forces made life extremely tough.

Explanation:

2 sheets of plywood will be needed.

Step-by-step explanation:

See the attached diagram.

Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square.  {Since each unit on the coordinate plane represents four feet}

Now, the two triangular plywood has area half of a unit square area.

So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.

Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.

Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need such sheets of plywood. (Answer)

The chemical reaction that will occur spontaneously is given by this chemical equation: Mg²⁺ + V²⁺ ----> Mg + V.

Reduction can be defined as a half-reaction through which the number of electrons (oxidation states) that is associated with the atoms of a chemical element are changed i.e reduced or decreased.

Based on the chemical reactions with the standard electrode reduction potentials, the half cell (Cu²⁺) with the higher reduction potential (+0.15) will be reduced while the half cell (V²⁺) with a lower oxidation potential (-1.18) will be oxidized and as such the chemical equation is given by:

The elements on the leading diagonals are: 4, -5 and -2

The elements under the leading diagonals are 0, 0 and 0

When the elements under the leading diagonals are 0, then the augmented matrix is row echelon form

Answer:

Explanation:

The type of reaction present in the equation(2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄)  is a double displacement reaction.

2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄

The reactant of the reaction is on the left side while the product of the reaction is on the right side.

Double displacement is a kind of reaction in which the two reacting compounds exchange their radicals or ions to form two new compounds. The anions and cations of the two different molecules switch places to form a new compound.

The reaction type is a double displacement reaction because the cations (mg and mn) and anions(so₃²⁻ and l⁻) switch positions.
