Answer:
The charge passes a given point in the conductor during this time is 9.8 C.
Explanation:
Given that,
Current = 1.4 A
Time = 7.0 sec
We need to calculate the charge during this time
Charge :
Charge is the product of current and time.
In mathematically form,

Where, i = cirrent
t = time
Put the value into the formula


Hence, The charge passes a given point in the conductor during this time is 9.8 C.
Answer:
The length of the pipe A is
= 0.4763 m & the length of the pipe B is
0.357 m
Explanation:
Fundamental frequency = 360 Hz
Velocity = 343 
(a). Length of the pipe is given by

Put all the values in above equation we get

= 0.4763 m
(b). Given that
The third harmonic of organ pipe B = the second harmonic of pipe A

Thus

Put all the values in above formula we get

0.357 m
Therefore the length of the pipe A is
= 0.4763 m & the length of the pipe B is
0.357 m
Answer:
4 days
either multiply 128 by .5 until you get to 2 counting each time or use 2 formulas ln(n2/n1)=-k(t2-t1) to get k then input k into ln(2)=k*t1/2
n2 is final amount and n1 is beginning and t is either time elapsed as in the first formula or the actual half life that is t1/2
Explanation:
Mass of the block = 1.4 kg
Weight of the block = mg = 1.4 × 9.8 = 13.72 N
Normal force from the surface (N) = 13.72 N
Acceleration = 1.25 m/s^2
Let the coefficient of kinetic friction be μ
Friction force = μN
F(net) = ma
μmg = ma
μg = a
μ = 
μ = 
μ = 0.1275
Hence, the coefficient of kinetic friction is: μ = 0.1275
Answer:
The value is 
Explanation:
From the question we are told that
The first position of the fulcrum is x = 49.7 cm
The mass attached is
The position of the attachment is
The second position of the fulcrum is 
Generally the sum of clockwise torque = sum of anti - clockwise torque
So

Here CWT stands for clockwise torque
So
