Answer:
Resistance of the circuit is 820 Ω
Explanation:
Given:
Two galvanometer resistance are given along with its voltages.
Let the resistance is "R" and the values of voltages be 'V' and 'V1' along with 'G' and 'G1'.
⇒
⇒
Concept to be used:
Conversion of galvanometer into voltmeter.
Let be the resistance of the galvanometer and the maximum deflection in the galvanometer.
To measure maximum voltage resistance is connected in series .
So,
⇒
We have to find the value of we know that in series circuit current are same.
For For
⇒ equation (i) ⇒ equation (ii)
Equating both the above equations:
⇒
⇒
⇒

⇒
The coil resistance of the circuit is 820 Ω .
Hi Randa, want me to help you with physics? The answer is when the object moves in a straight line.
Answer:
Explanation:
Centripetal acceleration (a) is defined as the square of an object's velocity (V^2) divided by the distance of the object from it's point/axis of revolution (r). So:
which allows us to solve for the velocity:
Answer:
1.60 g
Explanation:
From the attached file below:
we can deduce that:
The distance traveled by 2 s will be:
x = vt
x = 20 m/s × 2 s
x = 40 m
The length is quarter of the circle with radius r,
so; if 2 πr = 4 x
Then radius (r) will be:
r = 25.5 m
The centripetal acceleration can be expressed as:
so;
a = 15.7 m/s²
the magnitude of the acceleration experienced by your unfortunate passengers in terms of acceleration due to gravity is then determined by the equation:
∴ The magnitude of the acceleration experienced by your unfortunate passengers during the turn = 1.60 g
It uses C. Kinetic Energy
