Answer:
the gravitational pull is stronger the closer the object is to the magnet but gets weaker as you move the object away from the magnet
Explanation:
if you hold a magnet right over a nail it immediately shoot up onto the magnet
were as if you hold it at a distance it will move but not as fast
Answer:
Explanation:
Given that:
- mass of 1 skier,
- inclination of hill,
- length of inclined slope,
- time taken to reach the top of hill,
- coefficient of friction,
<em>Now, force normal to the inclined plane:</em>
<em>Frictional force:</em>
<em>The component of weight along the inclined plane:</em>
<em>Now the total force required along the inclination to move at the top of hill:</em>
<em>Hence the work done:</em>
<em>Now power:</em>
<u>So, power required for 30 such bodies:</u>
B because coyotes eat rabbits
So the coyote Is the predator while the rabbit is its prey
Answer:
1) Eo and Bo. They are maximum amplitudes. Answer 1 and 2
2) .w is angular frequency. Answer 2
3) k is wave number. Answer 1
Explanation:
The electromagnetic wave is given by
= E₀ sin (kx –wt)
This is the equation of a traveling wave on the x axis with the elective field oscillating on the y axis
The terms represent E₀ the maximum amplitude of the electric field,
The wave vector
k = 2π /λ
Angular velocity
w = 2π f
To answer the questions let's use the previous definitions
1) Eo and Bo. They are maximum amplitudes. Answer 1 and 2
2) .w is angular frequency. Answer 2
3) k is wave number. Answer 1
