An animal doesnt have a chloroplast
<span>We know the change of thermal energy is proportional to the specific heat of the matter, its mass and the change of temperatures, according the following formula:
Q = C*m*(Tf-Ti)
where:
Q is the heat added or removed (in joules, J)
C is the specific heat of the matter, in our case air 1,000 J/(Kg*C)
m is the mass, in our case 50 kg of air
Tf is final temperature
Ti is initial temperature
then:
Q = 1000 * 50 * (30-20) = 500,000 Joules
That means that 500,000 joules need to be added to increase temperature of the room 10 ÂşC (from 20 to 30 ÂşC)</span>
Answer:
Explained
Explanation:
Although Atom are electrically neutral. But atom atom is combination of nucleus and electrons. The nucleus of the atom is composed neutron and positively charged protons. On the outside of nucleus at some distance are the electrons which are negatively charged. So, there is difference in position of the two differently charge species. So, this way a electrically neutral atom can exert a electrostatic force on other electrically neutral atom
Because they are placed in different habitable zones
Answer:
clockwise direction
Explanation:
Direction of induced current is found with the help of Lenz's law . According to this law , the direction of induced current is such that it tries to neutralize or oppose the reason which creates this current .
In the given case , magnetic field is towards the viewer of the screen and it is increasing , so the induced current will have to create magnetic field in opposite to it . It means magnetic field will be created towards the screen into it . So the current will be induced in clockwise direction . This current will create magnetic field into the screen which will oppose increasing magnetic field out of screen .
