Answer:
The visible light frequency is 400 THz to 700 THz, approximately. A THz is a Terahertz, which is a unit of frequency equal to one trillion Hertz.
The ideal mechanical advantage of a compound pulley is
the number of strands of rope supporting the load.
<h2>Olivia is on a Swing at Playground - Option 2 </h2>
Olivia is on a swing at the playground. Her kinetic energy increasing at x and her potential energy decreasing at x. At mean position velocity is maximum so kinetic energy ( K.E ) is also maximum and at mean position potential energy is minimum. Therefore, kinetic energy is increasing and potential energy decreasing at x.
It's a group wave, or something that happens simultaneously. Unless the meaning you need is a fun little body wave! (: There's no rules but to jump out of your seat with your arms up!
I hope all is well, and this is what you were looking for! Good luck, rockstar! (:
Answer:
<em>529.2N </em>
Explanation:
Given parameters:
Mass of the object = 54kg
Unknown:
Gravitational force acting on the mass = ?
Solution:
To solve this problem, the gravitational force acting on this body is tantamount to the weight of the object.
So;
Weight = mg
m is the mass
g is the acceleration due to gravity
Now;
Weight = 54 x 9.8 = <em>529.2N </em>
The gravitational force acting on the object is <em>529.2N </em>
