here we will use the torque balance about the knee joint
here we can say that
here torque due to weight is given as
now torque due to applied force of muscle
now by torque balance we will have
so here the magnitude of m will be 173 N
The answer would be B because humans cannot see electrons so we visualize the electrons due to the theory
Answer:
northern and southern sphere

Explanation:
because the roller coaster can't work without energy
Answer:
53.13 °
Explanation:
In order to do this, we just need to apply the following:
tanα = Dy/Dx
Where:
Vy: speed of the ball in the y axis.
Vx: speed of the ball in the x axis.
At this point we do not need the speed of the first ball after the collision because in that moment is already heading in the direction that we are looking for. Therefore, we just need to use the innitial data to calculate the direction which the first ball will go.
According to this, then:
tanα = (40/30)
tanα = 1.3333
α = tan⁻¹(1.3333)
<h2>
α = 53.13°</h2>
This means that the final direction of the first ball is 53.13° and in the x axis because the starting momentum of this ball in the x axis has not dissapeared.
Hope this helps
