The tension in the string supporting the rod and the attached weights is 7.11 N.
<h3>Tension in the string supporting the rod</h3>
The tension in the string supporting the rod and the attached weights is the sum of the weights supported by the strings.
T = (m1 + m2)g
where;
- m1 and m2 are the two masses supported
0.4lb + 1.2lb = 1.6lb = 0.725 kg
T = 0.725 x 9.8
T = 7.11 N

Answer:
<em>| Fn | = 258 N</em>
Explanation:
<u>Net Force</u>
The net force vector is the sum of all the force vectors applied to a body.
There are four forces applied to a car:
325N to the north
175N to the south
465N to the east
255N to the west
To simplify the calculations, we find the net force by each axis separately, considering forces to the right and upward as positive.
Fx = 465 N - 255 N = 210 N
Fy = 325 N - 175 N = 150 N
The magnitude of the net force is:
| Fn | = 258 N
fish have proteins known as walleye Pollock, this white fish is packed with protein. Three ounces (85 grams) contain 20 grams of protein and about 100 calories (21). Alaskan Pollock is an excellent source of omega-3 fatty acids. It also contains large amounts of choline and vitamin B12, as well as many other nutrients.

A ripple tank is a shallow glass tank of water used to demonstrate the basic properties of waves. It is a specialized form of a wave tank. The ripple tank is usually illuminated from above, so that the light shines through the water.
