Determine the direction of the effective value of g⃗ at a latitude of 45 ∘ North on the Earth.

Kitty [74]

To solve this, we simply use trigonometry
the effective value of g along the 45° angle is
g eff = g / sin 45
g eff = g / (√2 / 2)
g eff = 2g / √2
g eff = g √2 ≈ 6.94 m/s²

A typical american family uses 1000 kwh of electricity a month. what is the average rrns current in the 120 v power line to a ty

grandymaker [24]

Power = (1000 kilo-Watt-hr/mo) x (1000/kilo) x (mo/30day) x (day/24 hr)

Power = (1000 x 1000 / 30 x 24) (kilo-watt-hr-mo-day/mo-kilo-day-hr)

Power = (1,000,000/720) watt

(voltage x current) = (1,000,000/720) watts

120v x current = (1,000,000/720) watts

Current = 1,000,000 / (720 x 120) Amperes

<em>Current = 11.57 Amperes</em>

An electron that has a velocity with x component 2.6 × 106 m/s and y component 4.0 × 106 m/s moves through a uniform magnetic fi

Natasha2012 [34]

Explanation:

It is given that,

The horizontal and vertical component of velocity of an electron is:

$v=(2.6i+4j)\times 10^6\ m/s$

The magnetic field acting there is given by :

$B=(0.037i-0.17j)\ T$

(a) The magnitude of the magnetic force on the electron is given by :

$F=q(v\times B)$

q = e

$F=e(v\times B)$

$F=1.6\times 10^{-19}\times ((2.6i+4j)\times 10^6\times (0.037i-0.17j))$

$F=-1.6\times 10^{-19}\times (-0.442\cdot10^{6}-0.1702\cdot10^{6})\ kN$

$F=9.79\times 10^{-14}\ kN$

(b) We know that the charge on proton is :

$q=+1.6\times 10^{-19}\ C$

The magnetic force as same as for electron but the direction is opposite i.e.

$F=-9.79\times 10^{-14}\ kN$

Hence, this is the required solution.
