The angle of bank needed, measured from the vertical is 86.6⁰.
<h3>
Banking angle of the circular path</h3>
The angle of bank needed, measured from the vertical is calculated as follows;
v = √(rg tanθ)
where;
- v is the speed = 1440 km/h = 400 m/s
- r is radius of the curve = 960 m
- g is acceleration due to gravity
- θ is the banking angle
400² = (960 x 9.8 x tanθ)
tanθ = 400²(960 x 9.8)
tanθ = 17
θ = arc tan(17)
θ = 86.6⁰
Thus, the angle of bank needed, measured from the vertical is 86.6⁰.

Answer:
The length of the sling is increased and the linear velocity of the stone stays the same.
Explanation:
Centripetal acceleration is given by
where <em>v</em> is the linear velocity and <em>r</em> is the radius of motion.
In terms of the angular velocity, <em>ω</em>
<em />, since
From the relation, is directly proportional to the square of the velocity and inversely proportional to the radius.
Hence, an increase in linear velocity results in an increase in the centripetal acceleration if the radius is kept constant. A decrease in the radius also causes an increase of the centripetal acceleration.

Answer:
The potential difference between the ends of a wire is 60 volts.
Explanation:
It is given that,
Resistance, R = 5 ohms
Charge, q = 720 C
Time, t = 1 min = 60 s
We know that the charge flowing per unit charge is called current in the circuit. It is given by :
I = 12 A
Let V is the potential difference between the ends of a wire. It can be calculated using Ohm's law as :
V = IR
V = 60 Volts
So, the potential difference between the ends of a wire is 60 volts. Hence, this is the required solution.
