Explanation:
Given
mass of first car 
speed 
radius of first turn=125 m
And Angular momentum is given by =mvr
Angular momentum of first car
similarly 
Thus angular momentum of first car is 1.54 times of second one
Hello,
The answer is A) a mixture. An element as defined as a pure substance, that cannot be broken down and most are typically naturally occurring. A compound occurs in chemical bonding. A substance is either a pure element or compound.
Here are some examples of field force:
1. <span>1) electrostatic force of attraction or repulsion on a charged particle in an electric field
2. </span><span>) magnetic force on charged particles moving at right angles with a magnetic field. Magnetic force also affects magnetic poles.
I hope this helps. </span>
