Banking angle is the angle between the normal horizontal path (N) and the curved banked path. The angle of banking of a curved path is defined as the angle through which the outer edge of the road is raised over the inner edge.

It is calculated as:

tan\theta = \frac{v^2}{rg}

Here,

v = Linear velocity of object

r = Radius of the curved path

a_c = Acceleration due to gravity

Rewriting the equation to solve for the radius we have that

r=\frac{v^2}{gtan\theta}

r = \frac{30}{(9.8)(tan 75\°)}

r = 24.6m

Therefore the radius of a bobsled turn banked at 75° taken at 30m/s is 24.6m

Which statement correctly distinguishes between all mechanical and all electromagnetic waves?
lutik1710 [3]

Answer: Mechanical waves carry energy through a medium; electromagnetic waves carry energy through media and space.

Explanation:

<u>The waves which require medium to travel are known as mechanical waves. </u>The waves carry energy forward by compression and rarefaction that is by changing density /pressure of medium particles.

<u>Electromagnetic waves can transfer energy through space as well as medium. </u>In an electromagnetic wave, electric field generates magnetic field and magnetic field generates electric field. Electric field and magnetic field are perpendicular to each other and to the direction of motion.

kondor19780726 [428]
The kinetic energy of the tomato is : 

K.E =  1/2 mv^2

K.E = 1/2 x 0.18 kg x 11 m/S^2

K.E = 0.99

Hope this helps
