Answer:
is this have picture with it so I can solve
Answer:
Explained below
Explanation:
For the geometric meaning, I've attached a parallelogram showing two vectors a and B and also the angle between them as θ.
We can see that the two vectors are adjacent to each other.
So the magnitude of the product of the two vectors is simply the area of the parallelogram which is base x height. Thus;
Magnitude = |a| sin θ × |b|
This can be rewritten as;
|a|•|b| sin θ
Answer:
The torque on the lever is 30.0 N m.
Explanation:
Torque is defined as tendency of a force to rotate a body around its axis. Mathematically written as:
Force applied on the lever arm at 90°= 15 N
Distance at which force is applied = d = 2.0 m
The torque on the lever is 30.0 N m.
Answer:
So that vehicles do not topple or skid off the road.
Explanation:
As a vehicle is negotiating a curve, two equal and opposite forces act on the vehicle; centripetal force which keeps it moving and centrifugal force which tends to throw it out of the path.
In order to avoid skidding off the road curved roads are banked. Banking a curved surface provides the centripetal force that points towards the center of the road hence the vehicle or car does not skid off or topple.
