Answer:
Rp = 10 Ohms; I = 0.9 Amps
Explanation:
Since, there are two resistors each with 20Ω connected in parallel, the total resistance of the combination (Rp) of the circuit is as follows:
i.e 1/Rp = (1/R1 + 1/R2)
1/Rp = (1/20Ω + 1/20Ω)
1/Rp = (1 + 1)/20Ω
1/Rp = 2/20Ω
1/Rp = 1/10Ω
To get the value of Rp, cross multiply
Rp x 1 = 10Ω x 1
Rp = 10Ω
Apply the formula
Voltage V = Current I x Total resistance Rp
I = V/Rp
I = 9V/10Ω
I = 0.9 Amps
Thus, the total resistance is 10 Ohms, the current through the ammeter is 0.9 Amps
Answer:by messing with the different organs and systems and causing damage them.
Explanation:
An excited atom can return to its ground state by absorbing electromagnetic radiation is false about the electromagnetic radiation.
Option B
<u>Explanation</u>:
In the scope of modern quantum theory, the term Electromagnetic radiation is identified as the movement of photons through space. Almost all the sources of energy that we utilize today such as coal, oil, etc are a product of electromagnetic radiation which was absorbed from the sun millions of years ago.
Various properties of electromagnetic radiations are a directly proportional relationship between the energy and the frequency, Inverse proportionality between frequency and the wavelength, etc. Hence, we can conclude that an "excited atom" can never return to its ground state by assimilating electromagnetic radiation and the 2nd statement is false.

Answer:
An applied force is a force that is applied to an object by a person or another object. If a person is pushing a desk across the room, then there is an applied force acting upon the object. The applied force is the force exerted on the desk by the person.
It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
