Answer:
Give up.
Explanation:
Physics is horrible.
And that's the cold hard truth. :(
In order to get the magnitude of the electric field at the location of the test charge, you have to use the formula: E=Fe/q.
Given E as electric field strength; Fe as electric force = 0.751 N and q as charge = 5*10-5 C. Therefore,
E= 0.751 N / 5 * 10-5 CE=15020 N C-1 or V m-1 Electric field at the location.
The weight of the object is 679.1 N
Explanation:
The weight of an object is given by:
where
W is the weight
m is the mass of the object
g is the acceleration of gravity
For an object near the Earth's surface, the acceleration of gravity is
The mass of the object in this problem is
m = 69.3 kg
Therefore, its weight is

Answer:
5 m
Explanation:
30 m/s / 6.0 cycles/s = 5 m/cycle
Answer:
Jari
Explanation:
The question requires to know who is traveling faster. This is done by comparing the gradients. The steeper the slope (high gradient), the faster the speed and vice versa.
From Jari's line, the starting point is (0, 0) and another point is (6, 7)
The gradient being change in y to change in x
Change in y=7-0=7
Change in x=6-0=6
Slope is 7/6
For Jade, first point is (0, 10) then another point is (6, 16)
Change in y=16-10=6
Change in x=6-0=6
Slope is 6/6=1
Clearly, 7/6 is greater than 6/6 or 1 hence Jari is faster than Jade
