Answer:
0.31429 Amps
Explanation:
Using the "Ohm's Law" we can look for the current (amps) with a formula of I = V/R
Given:
Resistance (Ohm) = 350
Volts = 110
Solution:
I = 110v/350r
I = 0.31429 amps
a) x = 
at t = 5s

b) v = 
= 
at t = 5 s
v = 
c) a = 
= 28 - 12t
at t = 5 s
a = 28 -12*5= 28-60= -32 m/
d) At maximum positive coordinate velocity = 0
So, 

At t = 4.66 s

e) At t = 4.66 s
f) At maximum positive velocity a = 0


At t = 2.33 s
V = 
g) t = 2.33 s
h) When particle is not moving v = 0
So 

At t = 4.66 s
a = 
i) At t = 0s, X =0m
t = 5s, X = 100m
So, Displacement = 100m
Velocity = 
Answer:
Force, F = 2356.19 N
Explanation:
Given that,
Diameter of the circular tip, d = 1 mm = 0.001 m
Its radius, r = 0.0005 m
Pressure created, 
To find,
Force exerted on the nail.
Solution,
The pressure exerted by an object is equal to the force acting per unit area. Its formula is given by :



F = 2356.19 N
Therefore, the force exerted on the nail is 2356.19 N.
Gravity is an attractive force that works to pull objects together. If 2 objects are close the gravitational pull will be stronger
Mass and distance determine gravity. The farther two things are away from each other, the weaker the gravitational forces are, the less mass an object has the less gravitational force it exerts
