Answer:
Explanation:
For the problem, we should have same reynolds number
ρvd/mu = constant
1000×1×10⁻³×0.3×10⁻³/1.002×10⁻³ = 1400×0.5×d/600
d = 25.66 cm
Answer:
True
Explanation:
Because the resistors in series is the sum of the two resistors given as
R= R1+R2
While that of resistors in parallel is the sum of the reciprocal of the resistance given as
1/R = 1/ R1+ 1/R2
So that of series connection will be greater
The wave phenomenon known as "destructive interference".
One scale will have a weight of 1087.50 and the next will be 362.50
Answer:
1. Magnetic force = 4.56*10^-12 N
2. Acceleration = 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
Explanation:
Given Data:
B = 0.0040 T North
q = 1.6*10^-19 C
Mass of electron = 9.1*10^-31 kg
V = 9.5% of speed of light
= 9.5% *3*10^8
= 28.5*10^6 m/s west
So, B and v are perpendicular to each other.
Therefore, ∅ = 90°
1, Calculating the magnetic force using the formula;
F = qvBsin∅
= 1.6*10^-19 * 28.5*10^6*sin90
= 4.56*10^-12 N
Therefore, the strength of the force = 4.56*10^-12 N
2. Calculating acceleration using the formula;
F = ma
a = F/m
= 4.56*10^-12 /9.1*10^-31
= 5.01 *10^18 m/s^2
3. A) The direction of the moving electron will change but its speed will remain constant.
