C.

Newton’s Second Law is F=ma (force is equal to the mass multiplied by acceleration), however, the equation can be rearranged to isolate and calculate mass from force over acceleration. Therefore, m=F/a

Is it better to wire a house using a series circuit or a parallel circuit?

Svetach [21]

Answer: its better to use parallel because, in parallel connection there will be more advantages than a series connection. and also the electronic devices are wired in series so thats why you should use parralel in house wiring

so its c.

because the parallel is wired through the whole house so if one of the circuits fail youŕe not screwed

A proton, traveling with a velocity of 1.6 × 106 m/s due east, experiences a maximum magnetic force of 8.0 × 10-14 N. The direct

uranmaximum [27]

Answer:

The magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.

Explanation:

Given:

Velocity of proton $v = 1.6 \times 10^{6}$ $\frac{m}{s}$

Magnetic force $F = 8 \times 10^{-14}$ N

Charge of proton $q = 1.6 \times 10^{-19}$ C

The magnetic force experience by proton in magnetic field is given by,

$F =qvB \sin \theta$

Here magnetic force experienced by proton is maximum so we take $\sin \theta = 1$

$F = qvB$

$B = \frac{F}{qv}$

$B = \frac{8 \times 10^{-14} }{1.6 \times 10^{-19} \times 1.6 \times 10^{6} }$

$B = 0.312$ T

According to the left hand rule the direction of magnetic field is out of the page.

Therefore, the magnitude of magnetic field is 0.312 T and direction of the magnetic field is out of the page.
