Answer:
while we often confuse mass with weight, 47 kg is 47 x 9.8 = 460.6 Newtons. 9.8 is acceleration of gravity in m/sec/sec
Answer:
Hey!
Your answer is "First-Class Lever"
Explanation:
Here's an example!!
The fulcrum (the triangle) is between the load and effort! (in this case called the FORCE)
Hope this helps!
You could answer this right away IF you knew the length of each wave, right ?
Well, Wavelength = (speed) / (frequency).
Speed = 3 x 10⁸ m/s (the speed of light)
and
Frequency = 90.9 x 10⁶ Hertz.
So the length of each wave is 3 x 10⁸ / 90.9 x 10⁶ meters.
To answer the question, see how many pieces you have to cut
that 1.5 km into, in order for each piece to be 1 wavelength.
It'll be
(1,500 meters) divided by (3 x 10⁸ meters/sec) / (90.9 x 10⁶ Hz)
To divide by a fraction, flip the fraction and then multiply:
(1500 meters) times (90.9 x 10⁶ Hz)/(3 x 10⁸ meters/sec)
= 454.5
It’s definitely b Yk Why um I don’t really know butttt gut instinct
The slope of the illustrated graph would give us the velocity of the object whose motion is plotted in the graph.
<h3>What is velocity?</h3>
Velocity refers to the rate of movement of objects along a particular line. In other words, the velocity of an object is the speed of the object in a specific direction relative to time.
Also, velocity = displacement/time.
In the graph, the slope is given by: Δy/Δx = displacement/time = velocity.
