Explanation:
<u>Using Equations of Motion</u> :
(1) v = u + at
24 = 6.5 + a * 210
<u>a (Acceleration) = 0.083 m/s^2 </u>
<u>(</u><u>2</u><u>)</u><u> </u> v^2 = u^2 + 2aS
S = 576 - 42.25 / 0.166
<u>S (Distance travelled) = 3215.3 m </u>
(Option A seems a typo since the answer is 3215.3 m)
Answer:
Explanation:
When beam is balanced and not rotating with Suki standing on it , let reaction force on the supports be R₁ and R₂. Then
R₁ +R₂ = 336 + 590
= 929
Now the moment beam begins to tip , reaction on distant support R₁ = 0
only R₂ will exists on the support near to Suki.
Taking torque about this support of weight of beam acting from the middle point and weight of suki of 590N ,who is x distance from the support towards the other end.
336 x 1.5 = 590 x
x = .85 m
ie , from second support , Suki can not go beyond a distance of .85 m towards the second end.
Answer:
The magnitude of charge on each sphere is 
.
Explanation:
Given that,
Force of repulsion between the charges, F = 22 mN
The distance between spheres, r = 16 mm = 0.016 m
It is mentioned that both the spheres carry equal charges. The force between charges is given by :
So, the magnitude of charge on each sphere is . Hence, this is the required solution.
Answer:
Natural Sciences
Explanation:
This network would fall under the lens of Natural Sciences. This is based on what the family is currently watching. Nature documentaries focus on our Planet as well as all the wildlife in it. In these documentaries, they talk about how and why certain things in nature occur. All of this would be considered educational information on the subjects of Earth Science and Biology which are main subcategories under the lens of Natural Sciences.
A.) 3,800
* Add 1800+2000 because they are both going forward, and you are look for the total amount of forward force. Hope this helped good luck!!!
