Answer

Correct Answer is C (10% of the plant's energy is transferred

Explanation:

Ecosystem

ecosystem is a community where large number of living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.

Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.

producer like plants produce their food on their own. And primary consumers takes their food from producers.

According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred

A sample of chloroform is found to contain 12.0 g of carbon, 106.4 g of chlorine, and 1.01 g of hydrogen. If a second sample of

GREYUIT [131]

Given:

Sample 1:

Chloroform is $CHCl_{3}$

12 g Carbon

1.01 g Hydrogen

106.4 g Cl

Sample 2:

30.0 g of Carbon

Solution:

mass of chloroform from sample 1:

12 + 1.01 +106.4 =119.41 g

Now, for the total mass of chloroform in sample 2:

mass of chloroform $\times$ $\frac{given mass of carbon}{mass of carbon atom}$

mass of chloroform = 119.41 $\times$ $\frac{30}{12}$ = 298.53 g

How much force is required to hold an empty carton of volume 1.5 L beneath the surface in a sink of water? Assume the carton is

Gwar [14]

Answer:

It will require 14.715 N of force to hold the cartoon beneath the water.

Explanation:

Given the the volume of cartoon is 1.5 liters.

We need to find the force required to hold this cartoon beneath the water.

As we know from the Archimedes principle that the net force is equal to the volume of liquid displaced.

Given volume of the cartoon is 1.5 liters. So, 1.5 liters of water will be displaced.

And we know the density of the water is $1000\ kg/m^3$ . That is $1\ kg/L$

And $g=9.81\ m/s^2$

$F_N=\rho Vg\\F_N=1\times 1.5\times 9.81\\F_N=14.715\ N$

So, it will require 14.715 N of force to hold 1.5 liter volume of cartoon beneath the water.

When solar flares increase solar wind from the corona what do they cause in earth's upper atmosphere?

Strike441 [17]

They cause magnetic storms. A magnetic storm is a fleeting disturbance of the Earth's magnetosphere. A magnetic storm is caused by a solar wind shock wave associated with solar coronal mass ejections, coronal holes, or solar flares. It typically strikes the Earth's magnetic field 24 to 36 hours after the event.

on a Powerline birds can enjoy sitting from one live wire to the other. However,if a person touches it,then the person will die

Alika [10]

Answer:

Due to potential difference (elaborated in explanation)

Explanation:

When a bird sits on a power line, its whole body is in contact with the power line. It does not have any contact with the ground or anything at a lower potential. Hence, the current does not flow through the bird's body, because there is no potential difference available as a driving force.

Now, when a person touches the power line his hand is at a higher potential provided by the power line, while the rest of his body is connected to the ground, usually through legs. The current always looks for a path from high potential to low potential. Therefore, the body of the person serves as the path for the current. Heavy current flows through the body and the person dies within split seconds.

What role do currents play in transporting heat? How does water temperature affect land nearby?

yarga [219]

When warm currents move over cool land surface, they dissipate heat due to the temperature gradient . They hence warm up the land they blow over. If a cold current blows over warm land, the land loses heat to the current. This is how currents distribute heat across the earth.

When the current blow from water to land, the current will be warm or cold depending on the water temperatures. Therefore, they will warm up or cool the adjacent land mass.
