A uniform electric field, with a magnitude of 370 N/C, is directed parallel to the positive x-axis. If the electric potential at

dem82 [27]

Answer:

$\Delta U = 0.2072 J$

Explanation:

Potential difference between two points in constant electric field is given by the formula

$\Delta V = E.\Delta x$

here we know that

$E = 370 N/C$

also we know that

$\Delta x = 2.1 - 1.9 = 0.2 m$

now we have

$\Delta V = 370 (0.2) = 74 V$

now change in potential energy is given as

$\Delta U = Q\Delta V$

$\Delta U = (2.80 \times 10^{-3})(74)$

$\Delta U = 0.2072 J$

How do streams change as they flow from mountains down to plains? Plz help URGENT I need it today

lisov135 [29]

They start as one stream, then get curvier, then empy into a delta. A delta is a ton of streams of water. It is one, then empties out into a ton of streams.

Almonds cost $3.49 per pound. A bag of almonds costs $6.95. to the nearest whole pound, about how many pounds of almonds are in

abruzzese [7]

The hint in this problem is in the word "about" or approximately how many pounds.

So we could find the solution by estimation through rounding off.

We know that almonds cost about 3.50 per pound and a bag costs about $7.00.

Dividing 7 by 3.50 per pound, will give us $7 ÷ $3.50 = 2 pounds.

The answer is 2 pounds.

You go rock climbing with a pack that ways 79 N and you reach a height of 30 m. How much work did you do to lift your pack? If y

Vanyuwa [196]

When you climb, earth exerts gravitational force on pack in downward direction(pointing towards the center of earth).
In order to climb, you need to work against work done by gravity on the pack.
Hence work done by you = work done by gravity on pack
= Force x displacement = 70 x 30 = 2100 J.
