The answer for this equation is A
It is a scaler because it’s only fully describes by a magnitude and a numerical alone
Answer:J equals 4.65 hope I helped(:
Explanation:
2j+j+j−3=17
Simplify both sides of the equation.2j+j+j−3=17
Simplify: 2j+j+j+−3=17(2j+j+j)+(−3)=174j+−3=174j−3=17
Add 3 to both sides.4j−3+3=17+34j=20
Divide both sides by 4.4j/4 = 20/4 j = 5
<h2>It takes 1.3 sec for the object to reach the ground.</h2>
Explanation:
Potential energy :
Potential Energy is the energy stored in a body or system by virtue of its position in a field of force or by its configuration
KINETIC ENERGY :
The energy possessed by a body by virtue of its motion is called its kinetic energy.
Given : v = 12 m/s
height = 32 m
just before hitting the ground,
Potential Energy = kinetic energy
mgh = 1/2 mv²
gh = 1/2 v²
9.8 x 32 = 1/2 v²
627.2 = v²
v = 25.04 m/s
we know that v = displacement /time
= 25.04 = 32 /t
t = 1.3 sec
It takes 1.3 sec for the object to reach the ground.
An orange looks orange because it reflects most of the orange light
that hits it, and absorbs most of the light of other colors that hits it.
If there's no orange light hitting it, then even if there's light of other
colors, the orange will appear very dark, almost black.
