Answer:

Metamorphosis are the series of processes involved in the development of organisms, mostly insects after the egg is hatched.

Insects undergo complete or incomplete metamorphosis

Complete metamorphosis involves 4 stages which is the development from egg to larva to pups to adults in a step wise manner e.g butterfly, moth etc

Egg—> Larva—> Pupa—> Adults

In incomplete metamorphosis the stages are 3 and it involves development from egg to nymph to adults. E.g cockroach

Egg—> Nymph—> Adults

A gry is an old English measure for length, defined as 1/10 of a line, where line is another old English measure for length, def
Valentin [98]

Answer:

0.2448 point²

Explanation:

1 gry = 1/10 line

1 line = 1/12 inch

=> 1 gry in inches = 1/10 * 1/12 = 1/120 inch

=> 1 inch = 120 gry

1 point = 1/72 inch

=> 1 inch = 72 points

Therefore,

120 gry = 72 points

=> 1 gry = 3/5 point

Therefore,

1 gry² = (3/5)² point²

1 gry² = 9/25 point²

This means that 0.68 gry² will be:

0.68 gry² = 0.68 * 9/25 point²

=> 0.68 gry² = 0.2448 point²

A tiger runs one kilometer. The tiger does 15,000 J of work and has a total power output of 500 W. How many minutes does it take
defon
Power is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. <span>As is implied by the equation for </span>power<span>, a unit of </span>power <span>is equivalent to a unit of work divided by a unit of time. The formula would be as follows:

P = W/t 

We calculate as follows:

500 W = 15000 J / t
t = 30 s</span>

What is the mass of the other block?
xeze [42]

Let us consider the tension produced on both the sides of the rope is T.

We have been given that the rope is mass less and the rope is passing through a pulley which is stationary.

Let\ m_{1} and\ m_{2}\ are\ the\ masses\ of\ two\ blocks

Let\ m_{1}\ is\ moving\ in\ vertical\ upward\ direction\ while\ m_{2}\ is\ in\ downward\ \ direction

Hence\ m_{2} =4.5\ kg

The body is moving downward with an acceleration of  \frac{3}{4} g

As the rope is the same one which is passing over a mass less pulley and connected by two masses,hence, acceleration of each block will be the same in magnitude.

For\ body\ m_{1}

Here the tension is acting in vertical upward direction and the  weight is acting in vertical downward direction. Here,the body is moving in vertical upward direction. Hence, the net force acting on it is-

                           T-m_{1} g=m_{1}a       [1]

    For\ body\ m_{2}

Here the tension is acting in vertical upward direction while weight is in vertical downward direction. The body is moving in downward direction. Hence the net force acting on it will be-

                            m_{2} g-T=m_{2} a   [2]

Combing 1 and 2 we get-

                          T-m_{1}g=m_{1}a

                          m_{2} g-T=m_{2} a

                      -------------------------------------------------

                      [m_{2} -m_{1} ]g=a[m_{1}+ m_{2}]

                      [4.5-m_{1}]g =\frac{3}{4}g[4.5+ m_{1}]

                      4[4.5-m_{1}] =3[4.5+m_{1} ]

                      7m_{1} =4.5 kg

                      m_{1} = 0.64286 kg    [ans]
