B) 37 V
The potential difference between point a and point b is equal to 37 V
The potential difference across a and b can be calculated by finding the equivalent resistance of the resistors R1, R2 and R3 and then by applying Ohm's law.
Given:
R1 = 3.0 Ω
R2 = 8.0 Ω
R3 = 10.0
Current = I = 5 A
To calculate equivalent resistance of the circuit:
R2 and R3 are connected in parallel configuration. The equivalent resistance of R2 and R3 can be calculated as
Resistance R1 is in series with Rp. The equivalent series resistance is calculated as
Thus the given 3 resistor circuit can be written as an equivalent resistance Rs equal to 7.44 Ω through which current I passes.
By Ohm's law;
If V is the potential difference between a and b
Potential difference across points a and b = Current flowing through the circuit × Resistance between points a and b
37.2 V ≈ 37 V
Therefore, the potential difference between point a and point b is equal to 37 V

c.neither
d.sample 1
B) 100 kg person
C) 412 kg motorcycle
D) 2540 kg elephant
The object having higher mass will experience higher gravitational force. Among the given things 2540 kg elephant experiences larger gravitational force.
Gravitational force is the force acting down wards which pulls all objects in the earth surface into the ground. Gravitational force is comparatively weaker than nuclear force and magnetic force.
Gravitational pulling experienced by a body is depends upon the height it exists and the mass of the body. As the height from the earth's surface increases, gravity decreases.
Similarly higher the mass of a body, higher will be attractive pull by the earth. The equation for gravitational force is written below:
Force = G m /r², here r is the distance from the earth surface or theoretically for earth it is the radius.
Thus, as mass increases so does gravity. Therefore, a 2540 kg elephant experience highest gravitational force among the other options.

Answer: Streptococcus.
Explanation:
The Bacteria and Archaea domains are prokaryotes, they contain no nuclues or organelles, only a circular chromosome. They cannot form multicells organisms. Archaea can be found in extreme evironments, such as hot springs and deep sea vents.
