Step-by-step explanation:
Given:

This field will have a scalar potential
if it satisfies the condition
. While the first x- and y- components of
are satisfied, the z-component doesn't.


Therefore the field is nonconservative so it has no scalar potential. We can still calculate the work done by defining the position vector
as

and its differential is

The work done then is given by



Answer:
C. 50 degrees
Step-by-step explanation:
Because 6x + 5x = 110° and x = 10
5×10 = FEG 50°
Answer:
The first table.
Step-by-step explanation:
Every single time, the x is being multiplied by 3 to get the y, and that means its proportional. Also, the second one is for sure NOT proportional
The group rent 11 river rent tubes and 4 cooler tubes.
Step-by-step explanation:
Rent for river rent tube = $20
Rent for cooler tubes = $12.50
Total spent = $270
Total tubes rented = 15
Let,
x be the number of river rent tube.
y be the number of cooler tubes.
According to given statement;
x+y=15 Eqn 1
20x+12.50y=270 Eqn 2
Multiplying Eqn 1 by 20

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 7.5

Putting y=4 in Eqn 1

The group rent 11 river rent tubes and 4 cooler tubes.

Answer:
width = 5cm
length = 10cm
Step-by-step explanation:
1. the ratio is 1:5 so 50 metres in real life is 10 centimetres on paper so length = 10 cm
2. 25 metres in real life is 5 centimetres on paper so width = 5 cm
