How can humans increase the rate of endangered of extinct species
labwork [276]

I would think A. Reduce Environmental Impacts.

If you build and populate more zoos, some of the endangered species might not be able to survive in captivity

If you introduce new predators they are going to kill all the endangered species and if you pass new laws about land use some people may kill the species

A lawn roller is rolled across a lawn by a force of 107 N along the direction of the handle, which is 13.5 ◦ above the horizonta
-BARSIC- [3]

Answer:

22.02 m

Explanation:

given,

Force, F = 107 N

angle made with horizontal = 13.5◦

Power develop by the lawn roller = 69.4 W

time = 33 s

distance = ?

Force along horizontal= F cos θ

          = 107 cos 13.5°= 104 N

Power = \dfrac{work\ done}{time}

69.4 = \dfrac{W}{33}

W = 2290.2 J

Work done= Force x displacement

displacement= \dfrac{2290.2}{104}

                      = 22.02 m

What are the methods of avoiding demagnetization​
lbvjy [14]

\\

The best method to use in prevention of self-demagnetization of a permanent magnet is by use of a keeper. Keepers were also commonly known as amateurs. They help in storing magnets safely, especially those that have low coercivity ( magnets that are extremely susceptible to stray fields).

A single conducting loop of wire has an area of 7.26E-2 m2 and a resistance of 117 Ω. Perpendicular to the plane of the loop is
cricket20 [7]

Answer:

\frac{dB}{dt} = 591.45 T/s

Explanation:

i = induced current in the loop = 0.367 A

R = Resistance of the loop = 117 Ω

E = Induced voltage

Induced voltage is given as

E = i R

E = (0.367) (117)

E = 42.939 volts

\frac{dB}{dt} = rate of change of magnetic field

A = area of loop = 7.26 x 10⁻² m²

Induced emf is given as

E = A\frac{dB}{dt}

42.939 = (7.26\times 10^{-2})\frac{dB}{dt}

\frac{dB}{dt} = 591.45 T/s
