Answer:
Number of electrons, 
Explanation:
Given that,
Charge on the fly, 
Let n is the number of electrons lose to the surface it is walking across. It is case of quantization of electric charge. It is given by :



n = 387500000 electrons
or

So, there are
electrons. Hence, this is the required solution.
Make an equation for both.
Ford= 15t+200
Chevy=20t
Now you must set them equal and solve for time t. Giving you 40 seconds. Now plug that in to the chevy equation to get 800 meters.
<em>To determine the y component of velocity of a projectile </em><u><em>sine </em></u><em>operation is performed on the angle of launch.</em>
<u>Answer:</u> <em>sine</em>
<u>Explanation:</u>
Thus 
The initial velocity u can be resolved along two directions.
Along the X direction initial velocity = u cos θ
Along y direction initial velocity= u sin θ
From the equation of motion 
Thus velocity along x direction
=u cos θ
Velocity along y direction
= u sinθ -gt
Sign of g is negative.
Answer:
The magnitude of the rate of change of the child's momentum is 794.11 N.
Explanation:
Given that,
Mass of child = 27 kg
Speed of child in horizontal = 10 m/s
Length = 3.40 m
There is a rate of change of the perpendicular component of momentum.
Centripetal force acts always towards the center.
We need to calculate the magnitude of the rate of change of the child's momentum
Using formula of momentum


Put the value into the formula


Hence, The magnitude of the rate of change of the child's momentum is 794.11 N.
