Option 4 ( R2 and R3 ) is the correct answer.
Explanation:
- In the below given diagram, we can see a circuit diagram that has four resistors such as R1, R2, R3, and R4.
- The opening of the circuit is noted as "a" and the ending is noted as "b".
- By observing the above diagram, we can clearly see that R2 and R3 are the pair of resistors that are connected in a parallel manner.
- Where all the other resistors such as R1 and R4 are neither connected in parallel nor in series.
Hence we can conclude that Resistor R2 and R3 are the ones that are connected in parallel.
Answer:
The gravitational acceleration is same for all objects.
a = b = c = d
Explanation:
Acceleration due to gravity or gravitational acceleration is the force exerted by Earth on unit mass of an object.
Acceleration due to gravity doesn't depend on the height of the object when the height is object is near to the surface of the Earth. Only when the height is comparable to the radius of the Earth, the value of gravitational acceleration changes.
But for the objects here, the gravitational acceleration is independent of the mass or height of the objects and has a constant value of 9.8 m/s².
Therefore, the gravitational acceleration of all the objects is same.
If 'a', 'b', 'c', and 'd' represent gravitational accelerations of objects 'a', 'b', 'c', and 'd' respectively, then a = b = c = d.
Answer:
To find the value of the unknown weight, we previously placed the 3 known weights and made a graph of the force against displacement
When hanging the weight is known, we measure the displacement and from the graph we can find the value of the hanging masses
We can also use the equation and multiply the constant K by the displacement and this is the applied weight.
Explanation:
For this problem we will use the translational equilibrium relation
F –W = 0
F = W
W = mg
The spring elastic force is
F = - k x
We substitute
k x = m g
Where we see that the force of the spring is equal to the weight of the body.
To find the value of the unknown weight, we previously placed the 3 known weights and made a graph of the force against displacement
When hanging the weight is known, we measure the displacement and from the graph we can find the value of the hanging masses
We can also use the equation and multiply the constant K by the displacement and this is the applied weight.
