The best ways to determine the safest driving speed are to 1) know the speed limit, and 2) maintain a safe following distance.<span> The safe following distance is to be enough distanced form the vehicle in front of you. But how much is enough?
A </span>driver<span> should ideally stay at least two seconds behind any vehicle that is directly in front of his or her vehicle.</span>
Answer
given,
copper rod length = 50 cm
density of the copper = 8.92 g/cm³
iron rod length = 50 cm
density of iron = 7.86 g/cm³
mass of iron = density × volume
m_i = 7.86 × A × l/2
m_c = 8.96 × A × l/2
taking the intersection of copper and iron rod be starting point cooper side is taken as positive side and iron side length is taken to be -ve side.
center of mass
=
=
=
=
= 0.015793 m
= 1.579 m (+ve)
center of mass shift to cooper because cooper is heavy.
Answer:
Explanation:
When the circuit elements are connected in series, the current in each element is same but the potential difference is different.
So, as one of the circuit component breaks off or burnt, all the other components are also not working as the circuit becomes open and no current is flowing through the circuit.
Answer:
Explanation:
which is the final velocity minus the initial velocity in the numerator, and the change in time in the denominator. For us:
so
a = .92 m/s/s (NOT negative because you're speeding up)
