1) Centripetal acceleration:
2) Centripetal force: 6942 N
Explanation:
1)
For an object moving in uniform circular motion (=circular motion with constant speed), the net acceleration is the centripetal acceleration, directed towards the centre of the trajectory and whose magnitude is given by
where
v is the speed
r is the radius of the circle
For the car in this problem, we have
v = 14 m/s is the speed
r = 50.0 m is the radius
Substituting, we find the acceleration:
2)
The net force acting upon the car is the centripetal force, also acting towards the centre of the circular path, and whose magnitude is given by
where
m is the mass
a is the centripetal acceleration
For the car in this problem, we have:
m = 1780 kg is the mass
is the acceleration
Substituting, we find the centripetal force:

<u>Answer</u>:
Mathew, a farmer, cultivates monocultures of wheat. The negative effect that the monoculture farming have on Mathew’s land will be C. nutrients will not be recycled into the soil.
<u>Explanation</u>:
Monoculture farming is the practice of cultivating a single species of crop or plant at a time on farm. Growing the same crop again on the same land yearly destroys the nutrient of soil. It destroy the quality of soil and made farmers use more fertilizers.
The quality of the crop is degraded as it will not get the essential nutrients. But this practice is very popular as it increases the productivity of a particular species of crops. So by using this method, mathew will get these disadvantages.
Other options are incorrect as this practice will not cause water pollution. Neither it would produce greenhouse gases, nor it would decrease crop productivity.

Explanation:
(a) Formula to calculate the density is as follows.
=
=
Now, calculate the charge as follows.
=
= C
or, = 101.06 nC
(b) For r = 6.50 cm, the value of charge will be calculated as follows.
=
= 7.454
