Answer:
=8.0 Watts
Explanation:
Power is a ratio of work done over time. The power in an electric circuit is calculated using the following formula:
P=I²R
P is power, I is current, R is resistance
Therefore, Power= 4²ₓ 0.5Ω
=8.0 Watts
Scientists refute the early atomic theory claim that atoms were indivisible as “Scientists bombarded atoms of large mass with neutrons, observed reaction products with much smaller mass, and described this result as fission”
.
Answer: Option D
<u>Explanation:
</u>
John Dalton was the first one to propose a model for atomic structure. According to him, atoms were tiny, indivisible materials which are used as building blocks of every elements. This formed the basis of atomic structure at that time.
But with the time, different experiments were performed by Rutherford, Bohr, Sommerfield and found that there is discrepancy in the fundamental postulates of atomic theory. Then the success of nuclear fission reaction completely refute the Dalton’s postulates of atomic theory. Because according to Dalton, atoms cannot be divided further.
But in nuclear fission reaction, scientists bombarded atoms of large mass with neutrons and the products are formed as elements of smaller mass compared to reactants. So, this proved that atoms can be divided further by neutrons. Thus, nuclear fission reaction made the scientists to completely refute the early atomic theory claim.
it is true. the trajectory reaches the value of zero at the top
Answer:
625 N
Explanation:
The impulse given to the nail is equal to the change in momentum of the hammer:
where
F is the force exerted by the hammer
is the time of contact
is the mass
is the change in velocity of the hammer
Substituting the data and re-arranging the equation, we can find the force:
Answer:
The correct answer is - Damage to the nerves that control the diaphragm.
Explanation:
Abdominal breathing is a condition in which inferior half of the lungs can be seen relaxing or contracting and expanding with the breath. This condition occurs due to the various conditions that lead to the respiratory.
It is cause due to the damage to nerves that control the diaphragm. The phrenic nerve is one of the nerve of diaphragm initiates in the neck and passes down.
Thus, the correct answer is - Damage to the nerves that control the diaphragm.
The phrenic nerve is a nerve that originates in the neck (C3–C5) and passes down between the lung and heart to reach the diaphragm.
