Answer:
Option (1) f = 1
Explanation:
Formula for Frequency (F) = 1/t where t = Time in seconds.
F = 1/1
F = 1 hz ( hz or hertz is the unit for Frequency ).
Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.
Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.
Directive Property – A freely suspended magnet always points in a north-south direction.
Have a good day!
Atoms of elements hook up to form molecules of compounds.
In this picture, you have 2 atoms of the element 'Hydrogen'
and one atom of the element 'Oxygen', hooked up to form
one molecule of the compound 'Water'.
Answer:
Explanation:
Step one:
Given data
work-done in dragging the trash= 236J
applied force= 18.9N
distance moved= 24.4m
Required
The angle of the applied force
Step two:
We know that work done is
WD= F * distance
<em>The work is the product of the horizontal component of the force and the distance.
</em>
Horizontal force = 236 ÷ 24.4
= 9.67 N
Cos θ = Horizontal force ÷ Actual force
Cos θ = (236 ÷ 24.4) ÷ 18.9 = 236 ÷ 461.16
The angle is approximately 59˚
Hello there!
For this:
1). Convert 10km to meters!
2). Convert the 30 minutes into seconds!
3). Use the following formula to solve for speed!
speed= distance/time
Note: The units should automatically work out to m/s. :)
My goal is to make sure you understand the problem, which is why I won't be giving you the answer. It'll be more work now, but less work in the future! :)
Hope this helped!
