A forest ecosystem describes the community of plants, animals, microbes and all other organisms in interaction with the chemical and physical features of their environment: Specifically, a terrestrial environment dominated by trees growing in a closed canopy — a forest, in other words.

Hope this helps you buddy! :)

vovikov84 [41]

Answer:

Secondary current is  8A

Explanation:

Data :

Primary supply = Vp = 240 V

Secondary supply = Vs = 60V

Primary current = Ip = 2A

Secondary current = Is = ?

Formula  :     Vp × Ip = Vs × Is

So for secondary current formula becomes

          Is = (Vp/Vs)×Ip =  (240/60) × 2

     Is = 4 × 2 = 8A

A 1200 kg car traveling at 60 mph quickly brakes to a halt. The kinetic energy of the car is converted to thermal energy of the
ololo11 [35]

Answer:

 ΔT = 59.9 ° C

Explanation:

For this exercise the brake energy is totally converted into heat

Let's calculate the vehicle energy

       K = ½ m v²

Let's reduce the units to the SI system

       v = 30 mph (1609.34 m / mile) (1h / 3600s) = 13.41 m / s

      Em = K = ½ 1200 13.41²

      K = 1.079 105 J

All this energy is transformed into heat

     Em = Q

The expression for heat is

     Q = m  c_{e} ΔT

     ΔT = Q / m c_{e}

The specific heat of iron is c_{e} = 450 J / Kg ºC

     ΔT = 1,079 105 / (4.0 450)

     ΔT = 59.9 ° C

How does the speed of light in glass depends on the frequency
Naddik [55]

Answer:

Frequency is of light depends upon the body that emits it. While wavelength depends on the medium through which it travels in vacuum the product of wavelength and frequency is the same while in other mediums the light of higher wavelength travels faster besed on refractive index. So light velocity depends on both frequency and wavelength.

A hockey puck has a coefficient of kinetic friction of μk = .35. If the puck feels a normal force (FN) of 5 N, what is the frict
alina1380 [7]

Answer:

The frictional force is  F_f =  1.75 \  N

Explanation:

From the question we are told that

     The coefficient of kinetic force is  μk = 0.35

     The normal force felt by the puck is  F_N  =  5 \  N

Generally the frictional force that acts on the puck is mathematically represented as

          F_f =  \mu_k  *  F_N

=>       F_f =  0.35  *  5

=>       F_f =  1.75 \  N
