Answer:
Current through each resistor is 2 A.
Explanation:
Given that,
Voltage of a battery, V = 5 volts
Resistance 1, R = 1.25 ohms
Resistance 2,R' = 1.25 ohms
Both resistors are connected in series. The equivalent resistance is given by :
R" = R + R'
R" = 1.25 + 1.25
R" = 2.5 ohms
The current flowing throughout all resistors is same in series combination of resistors. Current can be calculated using Ohm's law as :
I = 2 A
So, the current through each resistor is 2 A. Hence, this is the required solution.
Answer:
Momentum of block B after collision =
Explanation:
Given
Before collision:
Momentum of block A = =
Momentum of block B = =
After collision:
Momentum of block A = =
Applying law of conservation of momentum to find momentum of block B after collision .
Plugging in the given values and simplifying.
Adding 200 to both sides.
∴
Momentum of block B after collision =
Answer:
position as a function of time is y = 0.05 × cos(9.9)t
Explanation:
given data
mass = 5 kg
length = 10 cm = 0.1 m
displaced = 5 cm
to find out
position as a function of time
solution
we will apply here equilibrium that is
mass × g = k × length
put here value and find k
k =
k = 490 N/m
and ω is
ω =
ω =
ω = 9.9
so here position w.r.t time is
y = 0.05 × cosωt
y = 0.05 × cos(9.9)t
so position as a function of time is y = 0.05 × cos(9.9)t
