Answer:

Answer:

safe speed for the larger radius track u= √2 v

Explanation:

The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.

Also given that r_1= smaller radius

r_2= larger radius curve

r_2= 2r_1..............i

let u be the speed of larger radius curve

now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v

Why do electrons transfer charge and not protons?
mel-nik [20]
<h2>Answer:Protons interact in ways that electrons do not. ... Electrons are not affected by the strong force, and so they only get trapped by the electrical attraction to the nucleus which is much weaker in ionized atoms.</h2><h2 /><h2>Explanation:Therefore it is easier for electrons to move away from one atom to another, transferring charge.</h2>

Momentum is what combination of variables?
BigorU [14]

p=mv

where p=momentum, m=mass and v=velocity.

Hence momentum is the combination of mass and velocity.

Hope this helps you!
