There are 60 seconds in a minute.

This means that 5 minutes would be 60 times 5.
60×5 = 300

There are 300 seconds in 5 minutes.

There are 60 seconds in 1 minute, and we're trying to find how long 5 minutes are.

Therefore, multiply 60 x 5, which equals 300.

There are 300 seconds in 5 minutes.

This is how manganese appears in the periodic table. The arrow is pointing to the atomic of manganese.
Liula [17]
The way an element is shown in the periodic table is called the element's symbol. In the case of manganese, it is Mn. Other information shown alongside the element's symbol is the atomic mass, which for manganese is 55, and the atomic number of the element, which for manganese is 25.

Please answer ASAP, and please don't joke around and actually do answer my question. I will give you brainliest if you answer it
hammer [34]

Answer:

30 feet

Explanation:

First off, if they are throwing at 12.0 m/s and it takes 2.5 seconds. It will be the act of multiplication.

12 times 2.5 is 30, because 12 times 2 is 24 plus 12 divided by 2 which is 6 so 24 plus 6 is 30.

A plane designed for vertical takeoff has a mass of 8.0 × 10³ kg. Find the net work done by all forces on the plane as it accele
artcher [175]

Answer:

<em>the net work done after starting from rest is =  2.4 × 10⁵ J</em>

Explanation:

Work: Work can be defined as the product of force and distance. The fundamental unit of work is Joules (J),  The unit of Energy is Joules (J), as such Energy and work are interchangeable during calculation, This is illustrated below

E = W = 1/2mv².......................... Equation 1

Where m = mass of the plane, v = velocity of the plane, E = Energy, W = work done.

v² = u² + 2as ................................. Equation 2.

Where v = final velocity of the plane, u = initial velocity of the plane, a = acceleration of the plane, distance of the plane.

<em>Given: a = 1.0 m/s², s = 30 m, u = 0 m/s (at rest)</em>

<em>Substituting these values into equation 2</em>

<em>v² = 0² +2×1×30</em>

<em>v² = 60</em>

<em>v = √60</em>

<em>v = 7.75 m/s</em>

Also given: m = 8.0 × 10³ kg, and v = 7.75 m/s

<em>Substituting these values into equation 1,</em>

<em>W = 1/2(8.0×10³)(7.75)²</em>

<em>W = (4.0×10³)(60)</em>

W = 240 × 10³ J

<em>W = 2.4 × 10⁵ J</em>

<em>Therefore the net work done after starting from rest is =  2.4 × 10⁵ J</em>

(1) <span>Electric current is defined as the rate of </span>charge<span> flow past a given point in an electric circuit. It is measured in Coulombs/second, also called Amperes. In </span>DC electric circuits<span>, it can be assumed that the </span>resistance<span> to current flow is a constant so that the current in the circuit is related to </span>voltage<span> and resistance by </span>Ohm's law, which is:
<span>
V = I*R
Where V = Voltage
I = Current
R = Resistance

(2) The answer is attached in image form down below(please find attachment)
(3) </span>The answer is attached in image form down below(please find attachment)

(4) <span>Renewable energy is the energy which is generated from the natural sources i.e. sun, tides, wind etc. Examples are: Solar Energy, Wind energy( windmill) etc. for electricity generation.
Advantages of Renewable Energy:
1) It is available in abundant quantity.
2) It is free to use.
3) It has </span><span>low carbon emissions, therefore it is considered as green and environment friendly.
Disadvantages of Renewable Energy:
1) It is not easy to setup plants and machinery for renewable energy.
2) Initial costs for setting up those plants and machinery is quite high.
3) The energy from the natural sources is not available 24/7. In Solar energy case, energy </span><span>can be used during the day time and not during night or rainy season etc.
</span>
Non-Renewable energy is energy which is taken from the sources that are available on the earth in limited quantity. Sources may be <span>fossil fuels, natural gas, oil and coal etc.
</span><span>Advantages of Non-Renewable Energy Sources:
1) They are easy to use.
2) They are cheap.

Disadvantages:
</span>1) They will expire some day (as they are limited).
2) The speed at which such resources are being used can have serious environmental changes.
3) They release toxic gases in the air when burnt which are the major cause for global warming.
<span>4) Since these sources are going to expire soon, prices of these sources are proliferating day by day.
</span><span>
Now you should judge all by yourself which is the better energy source.
