Answer:

Electric dipole

Explanation:

the axis of a dipole makes an angle with the electric field. depending on the direction (clockwise/anticlockwise) we can get the torque (positive/negative).

hope this helps :D

A horizontal force pushes a 26 kg sled along a driveway for a distance of 36 m. If the coefficient of sliding friction is 0.2, w

SVETLANKA909090 [29]

Answer:1834.56 joules

Explanation:

Distance=36m

Coefficient of friction=0.2

Mass=26kg

Acceleration due to gravity=9.8m/s^2

Reaction=mass x acceleration due to gravity

Reaction=26 x 9.8

Reaction=254.8N

Coefficient of friction=frictional force ➗ reaction

0.2=frictional force ➗ 254.8

Frictional force=0.2 x 254.8

Frictional force=50.96N

work=friction force x distance

Work=50.96 x 36

Work=1834.56

Work=1834.56 joules

You are driving on the highway, and you come to a steep downhill section. As you roll down the hill, you take your foot off the

wariber [46]

Answer:

Weight, air drag, normal.

Explanation:

Since the car is only rolling downhill, the forces that will come into play are: it's own weight (the gravitational force the Earth exerts upon the car), the air resistance (the force the air exerts upon the car, since it says it can't be ignored) and finally the normal force (the contact force the ground exerts on the car). There are no other forces sources.
