It is simply a question of the amount of water contained, a lake is much bigger than a pool. The energy ratio is just the ratio of the masses of water concerned. Thermal energy is the total kinetic energy of the particles in a substance .The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.

Humans require organ systems to carry out life processes. Single-celled organisms do not have organ systems and yet they are abl

k0ka [10]

Answer: is Organelles present in single-celled organisms act in a manner similar to organ systems

Explanation:

Multicellular organisms organ system play a critical role for the smooth functioning of whole body. Millions of cells combined to make an organism. The role of organ system in whole body is to provides oxygen and nutrients to the cells and eliminates the toxic material such as carbon dioxide. Organ systems like, respiratory system, digestion system, and cardiovascular play an important role in the human body to perform various functions for its survival.

Unlike multicellular organisms the unicellular only consists of single cell e.g. prokaryotic organisms and eukaryotic organisms namely, Amoeba, Euglena, salmonella, Fungi etc. Single celled organisms are able to carry out all processes mandatory for the sustenance of life with the help of single cell only e.g. respiration and digestion.They can survive with the help of single cell. Unlike multicellular organisms unicellular do not require multiple number of cell for its survival.

A loop of wire is perpendicular to a magnetic field such that the field is coming straight at you through the loop. The field be

Umnica [9.8K]

Answer:

we will have induced magnetic field towards us

now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.

Explanation:

As per lenz law we know that the rate of change in magnetic flux linked with the closed loop will induced EMF in the loop and the direction of this induced current in the loop will always oppose the causes due to which it is induced

Here we know that magnetic field is straight towards us and it start decreasing with time

So we can say that flux linked with the coil will also decrease with time

Now as per lenz law the induced magnetic field of the loop is in such a direction that it will increase the magnetic flux in the coil.

So we will have induced magnetic field towards us

now in order to induce the magnetic field towards us we must have induced current in the loop and its direction is counterclockwise.

A 50 kg pitcher throws a baseball with a mass of 0.15 kg. If the ball is thrown with a positive velocity of 35 m/s and there is

Andreas93 [3]

The velocity of the pitcher is 0.105 m/s in a direction opposite to the velocity of the ball.

When no external force acts on a system, the total momentum of the system is conserved. The total initial momentum of the system is equal to the total final momentum of the system.

The pitcher and the ball are initially at rest, therefore, the total initial momentum of the system is zero.

Since no external forces act on the system comprising of pitcher and the ball, the total final momentum of the system is also equal to zero.

If the mass of the pitcher is mp and its speed is vp, the mass of the ball is mb and the ball's speed is vb, then the final momentum of the system of pitcher and the ball is given by,

$p=m_pv_p+m_bv_b=0$

Therefore,

$v_p=-\frac{m_b}{m_p} v_p$

Substituet 0.15 kg for mb, 50 kg for mp and 35 m/s for vb.

$v_p=-\frac{m_b}{m_p} v_p=-\frac{0.15 kg}{50 kg} (35m/s)=-0.105 m/s$

The pitcher has a velocity 0.105 m/s opposite to the direction of the velocity of the ball.
