Answer:
In a nutshell, units of A and B are and , respectively.
Explanation:
From Dimensional Analysis we understand that and have length units () and have time units (). Then, we get that:
(Eq. 1)
(Eq. 2)
Now we finally clear each constant:
In a nutshell, units of A and B are and , respectively.
Answer:
C. over land in polar regions.
Answer:
Explanation:
moment of inertia of the door M = 1 /3 m ( l² + b² + d² )
= 1 / 3 x 7.5 x ( 2.3² + 1² + .03² )
= 1 / 3 x 7.5 x 6.2909
I = 15.7272.
moment of inertia of the door + small toy
15.7272 + .12 x .5²
= 15.7272 + .03
= 15.7572
Applying conservation of angular momentum law
mvr = M ω
m is mass of the toy thrown with velocity v at distance r from the axis , M is moment of inertia of door + toy and ω is angular velocity ith which door opens.
.12 x v x .5 = 15.7572 x .19
v = 49.89 m /s .
Answer:
Sorry but don't know how to calculate velocity
Explanation:
Answer:
Explanation:
length of the wire = L
Potential difference = Vo
Current = I
new length of the wire, L' = L/2
As we know that the resistance of the wire is directly proportional to the length of the wire.
As the length is halved so that the resistance is also halved.
Resistance = Voltage / Current
V = I R
So, Voltage is constant and the resistance is halved so that the current is doubled.
