The force on a charged particle in a magnetic field is given by
the speed of the charged particle = 10842 m/s.
Explanation:
F= q V B sinθ
F=force=3.5 x 10⁻²N
q= charge= 8.4 x 10⁻⁴ C
B= magnetic field= 6.7 x 10⁻³ T
θ=35⁰
Thus the velocity is given by V=
V=(3.5 x 10⁻²)/[(8.4 x 10⁻⁴)(6.7 x 10⁻³)(sin35)]
V=10842 m/s
The answer is d about the length and width if I’m not mistaken
Answer:
0.686 m/s
Explanation:
The principle of conservation says the sum of momenta before collision is equal to the sum of momenta after collision in an isolated system. Here, we assume the system is not acted upon by any external force.
The initial momentum = momentum of 1 st cart + momentum of 2nd cart
= 0.400 × 1.2 + 0.300 × 0 = 0.48 kg m/s
The final momentum = (0.400 + 0.300) × v (since they stick together)
0.700 v = 0.48
v = 0.686 m/s
Answer:
His displacement is 260 – 169 = 91 km
His distance traveled is (260 – 134) + ( 169 – 134 ) = 161 km
Explanation:
Answer: 28
Explanation:
Given
Circuit breaker current is
Power of the light bulb is
Voltage of the DC-circuit is
If the resistance are connected in parallel, they must have same voltage i.e. 120 V
So, Resistance is given by
For the 20 A current and 120 V battery, net resistance is
Suppose there are n resistance in the circuit connected in parallel.
Thus, there can maximum of 28 bulbs.
