Electrical resistance resists the rate of flow of charge (Current), so when resistance increases, current will decrease
In short, Your Answer would be "True"
Hope this helps!
Answer:
a. Gravity and c. Spring
Explanation:
Formula for work energy
whereas F is the force acting on the block, S is the distance traveled, and is the angle between 2 vectors F and S.
If F is perpendicular to S, then
a. Normal force is the reaction force acting from the ramp back on the wooden block. This force is perpendicular to the direction of sliding. Therefore this force would do no work.
b. Gravity is the force acting downward, this would have an angle of degrees so the work is non-zero.
c. Spring force would have the same direction as sliding so the work is non-zero.
d. Friction force would have the same direction as sliding. However, as this is a frictionless ramp, the friction coefficient would be 0. Friction force would also be zero and so as its work.
Answer:
8381
Explanation:
Workdone=Force x distance
W= 289x 29
W=8381J
The work of Charles Kuen Kao is likely to have been most influenced by the work of Christian Doppler. Both scientists are related with the phenomenon of wave. Christian Doppler is famous for its Doppler's effect. This effect can be seen when the source is moving w.r.t observer or vice versa.
Answer:
um this is not physics but the U.S. Food and Drug Administration (FDA)
Explanation: I don't know if that's the answer you were looking for but here you go.
