Materials that conduct heat and electricity well in the solid state result when metals bond with metals. <span>This type of bonding is called metallic bonding. Metallic bonding is when positive ions (metals) are in a 'sea of negative electrons'. The electrons are delocalised, which means they can move around easily and carry charge, and this enables it to conduct electricity, even in a solid state.</span>

Why do you think there are so many more autotrophs than consumers on Earth?<br> Helppp

There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

<h3>Function of Autotrophs </h3>

Autotrophs capture the energy required for every food chain or web from which sustains other organisms in the food chain form sunlight and chemicals. Also there is always more biomass present in the lower levels of the trophic system as biomass decreases as we move up the food chain.

Since autotrophs are producers, for a healthy food chain there would be more autotrophs than consumers.

Hence we can conclude that There are many Autotrophs than consumers because : Autotrophs are the bases of any food chain/web

In an inertia balance, a body supported against gravity executes simple harmonic oscillations in a horizontal plane under the ac

avanturin [10]

Answer:

2) f = 0.707 Hz

Explanation:

Given m₁ = 1.0 kg , f₁ = 1.0 Hz

So using the equation

f₁ = ( 1 / 2 π ) * √K / m₁

Solve to determine K' constant of spring

K = m * ( 4 π ² * f ² )

K = 1.0 kg * ( 4 π ² 1.0² Hz )

K = 39.4784176

So given 2.0 kg the frequency can be find using formula

f₂ = ( 1 / 2 π ) * √K / m₂

f₂ = ( 1 / 2 π ) * √39.4784176 / 2.0 kg

f₂ = 0.707 Hz

A flowerpot falls off a windowsill and falls past the window below. You may ignore air resistance It takes the pot 0.420 s to pa

eduard

Answer:

the distance of the top of the window below the windowsill from which the flowerpot fell is 0.31 m

Explanation:

given information:

time, t = 0.420 s

height, h = 1.9 m

the the vertical motion equation:

h = $v_{0}$ t + $\frac{1}{2} gt^{2}$

where

h = height (m)

$v_{0}$ = initial velocity (m/s)

t = time (s)

g = gravitational force (9.8 $m/s^{2}$ )

first we calculate the velocity of the flowers pot when it reaches top window

h = $v_{0}$ t + $\frac{1}{2} gt^{2}$

1.9 = $v_{0}$ (0.42) + ( $\frac{1}{2} 9.8 0.42^{2}$ )

$v_{0}$ = (1.9 - ( $\frac{1}{2} 9.8 0.42^{2}$ ))/0.42

= 2.47 m/s

now we can find the distance of the windowsil

$v^{2} =v_{0} ^{2}$ + 2gh

v = 0, thus

2gh = - $v_{0}^{2}$

h = - $v_{0}^{2}$ /2g

= $(- 2.47^{2} )$ / (2 x 9.8)

= 0.31 m
