Answer:
v = 2.974
Explanation:
Perhaps the formula should be
v = √(2*g*d (sin(θ) - uk*cos(θ) ) This is a bit easier to read.
v = √(2* 9.80*0.725(0.707 - 0.12*0.707) ) Substitute values. Find 2*g*d
v = √14.21 * (0.707 - 0.0849) Figure out Sin(θ) - uk cos(θ)
v = √14.21 * (0.6222)
v = √8.8422 Take the square root of the value
v = 2.974
Hello,
The 4 describes the amount of calcium in that compound.
Have A Good Day.
<span>Radio waves just like light waves can be reflected refracted and diffracted and polarized. The answer is True. </span>These characteristics are the common phenomena for electromagnetic (EM) waves, and Radio Waves are electromagnetic Waves so much so that they obey reflection, refraction, and diffraction.
Given that
Force (F) = 15 N ,
mass (m) = 5 Kg ,
acceleartion = ?
We know that, From Newtons II law
F = m. a
15 = 5 × a
a = 15÷ 5
a = 3 m/s²
acceleration of the ball is 3 m/s²
