Answer:

Explanation:

The formula for power :

P = VI

The formula for potential difference :

V = IR

Calculating P by inputting the formula of V :

P = (IR)(I)
P = I²R

Solving using the given values :

18 = I² x 6
I² = 3
I = √3
<u>I = 1.73A</u>

We need voltage first

P=V²/R
V²=PR
V²=18(6)
V²=108
V=√108
V=10.4V

Apply oHMS law

V/I=R
I=V/R
I=10.4/6
I=1.73A

Hurricane sandy produced some of the greatest destruction along the new jersey coast in communities situated along narrow strips

FrozenT [24]

The correct answer to fill in the blank would be:

“a barrier island”

Barrier islands are coastal landforms and a category of dune system that are remarkably even or lumpy areas of sand that was formed by wave and tidal actions that are parallel to the mainland coast. Due to this feature, there are no enough sand blockades to minimize the destruction by Hurricane Sandy.

When an object threw to the free space to make an angle of 25 degree at an initial speed of 15 m/sec, the ball takes time to rea

alekssr [168]

Answer:

The horizontal distance traveled by the projectile is 15.23 m.

Explanation:

Given;

angle of projection, θ = 25⁰

initial velocity of the projectile, u = 15 m/s

time of flight, t = 1.12 s

The the travelling path of the object is calculated as the range of the projectile

$R = u_x t\\\\R = (15\ Cos \ 25^0) \times 1.12\\\\R = 13.595 \times 1.12\\\\R = 15.23 \ m$

Therefore, the horizontal distance traveled by the projectile is 15.23 m.
