Answer:
The initial current, Io = 2.06×10^-4A
Explanation:
The I itial current ,Io of a circuit is given by:
Io = Vo/R
Where Vo = initial votage
R = resistance in ohms
Given:
Vo = 1.50V
R = 7290ohms
Io = 1.50/ 7290
Io = 2.06 ×10^-4A
Answer:
Explanation:
The two examples of contact forces are frictional force and applied force. The two examples of noncontact forces are gravitational force and magnetic force.
Answer:
Option A
Multiplanar step-up to balance
Explanation:
Resistance training exercises are the exercises that cause the muscles to contract against an external resistance leading to an increase in strength and endurance. Resistance training increases muscle strength by making your muscles work against a weight or force. Considering the options given, it's only Multiplanar step-up to balance which is an example of a strength level resistance training exercise for legs.
Net force = (mass) x (acceleration)
There are two forces acting on the barrel:
-- the force of gravity, downward;
-- the force of the rope, upward.
When these two forces are added together, their sum (the net force
on the barrel) causes the barrel to accelerate upward at 1.4 m/s² .
Net force = (Rope force) - (Grav force) = (mass) x (acceleration)
Grav force = 'weight' = (mass) x (grav) = (16 x 9.8) = 156.8 newtons
Net force = (mass x acceleration) = (16 x 1.4) = 22.4 newtons
Net force =
22.4 newtons = (Rope force) - (156.8 newtons)
Add 156.8 newtons to each side: Rope force = 22.4 + 156.8 = <em>179.2 newtons
