If a child pulls a sled through the snow on a level path with a force of 60 n exerted at an angle of 39° above the horizontal, find the horizontal and vertical components of the force.

Explanation:

Given that,

Force with which a child pulls a sled, F = 60 N

It is at an angle of  39° above the horizontal. We need to find the horizontal and vertical components of the force.

The horizontal component is given by :

The vertical component is given by :

So, the horizontal and vertical components of the force are 23.31 N and 18.87 N. Hence, this is the required solution.

connect the batteries in series and hope

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
