Answer:
Explanation:
The resistors in a unbalanced wheat stone bridge cannot be treated as a combination of series and parallel combination of resistors.
In case of balanced wheat stone bridge, the resistors can be treated as the combination of series and parallel combination.
Here, In the balanced wheat stone bridge
R1 and R2 be in series and Ra and Rx is series and then their combination is in parallel combination.
Answer:
21000 N
Explanation:
From the question given above, the following data were obtained:
Change in momentum = 105000 kg.m/s
Time = 5s
Force =?
Force is related to momentum and time according to the following formula:
Force = Change in momentum / time
With the above formula, we can calculate the force the white car experience during the collision. This can be obtained as illustrated below:
Change in momentum = 105000 kg.m/s
Time = 5s
Force =?
Force = Change in momentum / time
Force = 105000 / 5
Force = 21000 N
Thus, the white car experience a force of 21000 N during the collision.
Answer:
250 cm³
Explanation:
given,
Length of the Box, L = 5 cm
Width of Box, W = 5 cm
height of the box, H = 10 cm
Volume of the Box = L W H
V = 5 x 5 x 10
V = 250 cm³
Volume of the box is equal to 250 cm³
