Answer:
Thermal expansion causes the bar to expand in length (also, thermal contraction causes the bar to shrink). Having the meter measured in this way allows for consistency and can be easily converted.
Explanation:
Answer:
The period of the pendulum will increase.
Explanation:
The period of the pendulum will increase since g efective will decrease.
Then g efective is given by
g efective = g - a < g
If ⇒ T = 2π√(L/g)
and T' = 2π√(L/(g - a))
then T < T'
When the elevator accelerates downward, the hanging mass feels “lighter” – this means that the effective value of g has decreased due to the acceleration of the elevator. Since the period depends inversely on g, and the effective value of g decreased, then the period of the pendulum will increase
.
(i.e., its frequency will decrease and it will swing slower)
Voltage - V = IR : v= voltage i= current r= resistance
