I really hope this is right I think this is Diffuse I'm sorry if its worng
Answer:
We apply force to move the brick.
Explanation:
Let me first of define a force .
A force is something applied to an object or thing to change it's internal or external state.
Now if a brick is resting on smooth wood inclined at 30° to the horizontal for us to overcome the friction which is also a force we have to apply a force greater than the gravity force acting on the body and then depending on the direction of the applied force the angle to apply it also.
V=IR however in this case we will rearrange it into R= V/I. Which leads to R=15.0/0.30. And your answer becomes 50.
The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
<h3>What is the speed of wave?</h3>
Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,
Here, (f) is the frequency and (λ) is the wavelength.
The frequency is inverse of time. Thus, the value of frequency in time t is,
The speed of the wave is 0.5 m/s. Put the values in the formula,
Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

Answer: 1.8m
Explanation:
Using the principle of moment to solve the question which states that the sum of clockwise moment is equal to the sum of anticlockwise moments.
The boy moves in the clockwise direction towards the pivot while the girl moves in the anticlockwise direction towards the pivot.
Since moment = force × perpendicular distance
CW moments = 60×1.5 = 90Nm
ACW moments = 50×x = 50x
Equating both moments to get 'x'
90 = 50x
x =9/5
x = 1.8m
This shows that the girl must sit 1.8m from the other side for equilibrium.:
