Answer:
D. Resultant Vector
Explanation:
By definition, adding 2 vectors gives a resultant vector
Build up of pressure between tectonic plates .
Answer:
Opposite to the net force
Explanation:
The frictional force is a constant force that resists the motion of a body.
There are two classifications of frictional force
1) Static friction
2) Kinetic friction
When a force acts on two surfaces that prevent the sliding between them is the static frictional force.
When a force acts on a moving surface that opposes the motion of the surface is called the kinetic friction.
<em>The kinetic frictional force acts in the direction opposite to the motion and the net force.
</em>
The static and kinetic frictions are dimensionally the same quantity only the coefficient of the friction is higher for static friction.
Answer:
constriction is made in a clinical thermometer because it prevents the thermometric liquid from running back into the bulb.
Answer: 0.075
explanation:
you can use one of the equations of motion.
2as =v^2 - u^2
we shall make acceleration the subject as that's what we need to find out
a = (v^2 - u^2) / (2 × s)
now substitute the given values:
final speed would be zero as the airplane stops.
a = (75 - 0) / ( 2 × 500)
a = 75 ÷ 1000
a = 0.075 meters per second squared.
