Answer:
Impulse-The effect of force acting over time to change the momentum of an object.
momentum-The product of mass of a particle and its velocity.
Answer:
<em>The force applied to the car was 30,600 N</em>
Explanation:
According to the second Newton's law, the net force applied to an object of mass m is:
Where a is the acceleration at which the object moves. The net force can be also calculated as the sum of all forces acting on the body.
We have a car of m=2000 Kg, being accelerated at 5.5 m/s^2 by a force F (unknown) directed upwards.
Considering the force is upwards and the weight of the car (W) is directed downwards, the net force is:
Being W=m.g
Equating [1] and [2]:
Adding W:
Substituting:
F=30,600 N
The force applied to the car was 30,600 N
The energy stored in the magnetic field of this inductor is assessing the effect of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.
Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best known for altering behavior, worry can have magnetic effects on our physical health. Anxiety speeds up our heartbeat and breathing, magnetic blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.
