Ridge push

slab pull
Answer:
to the left.
Explanation:
We can use the equation where v is the velocity at time t and the velocity at . Since we want the acceleration we write this equation as:
Considering the <em>direction to the right as the positive one</em>, we have at , and at , so we substitute:
Where the minus sign indicates it is directed to the left.
Answer:
<em>The tension in the web is 0.017738 N</em>
Explanation:
<u>Net Force</u>
The net force exerted on an object is the sum of the vectors of each individual force applied to an object.
If the net force equals 0, then the object is at rest or moving at a constant speed.
The spider described in the question is hanging at rest. It means the sum of the forces it's receiving is 0.
A hanging object has only two forces: The tension of the supporting string (in our case, the web) and its weight. If the object is in equilibrium, the tension is numerically equal to the weight:
T=W=m.g
The mass of the spider is m=1.81 gr = 0.00181 Kg, thus the tension is:
The tension in the web is 0.017738 N
Answer:
8 mm
Explanation:
From the information given:
The Ampere circuital law can be used to estimate the magnetic field strength at two points when the distance is less than the radius and when the distance is greater than the radius.
when the distance is less than the radius ; we have:
when the distance is greater than the radius; we have:
Equating both equations together ; we have :
where; d = radius of the wire and r = distance;
R = 8 mm
Time should not be messed with
for bad things could happen
so think before you act or you'll regret it
