_______ currents assist in the transfer of thermal energy from warmer climates to cooler climates.

1 answer:

4 0

<span>It is convection currents that carry thermal energy from warmer places to cooler places. The process operates upon planetary scales, as suggested by the question, but also operates on more local scales such as in your own house. For example, if there is a heater within a single room within your house, convection will drive heat energy to adjacent colder rooms. </span>

Tema [17]

Answer:

The absolute value of the angular deviation is 39.3°.

Explanation:

Given that,

Current = 1.1 A

Distance = 0.9 cm

Magnetic field = 20μT

We need to calculate the magnetic field due to wire

Using formula of magnetic field

$B=\dfrac{\mu_{0}I}{2\pi d}$

Put the value into the formula

$B=\dfrac{4\pi\times10^{-7}\times1.1}{2\pi\times0.9\times10^{-2}}$

$B=24.4\times10^{-6}\ T$

$B=24.4\ \mu T$

We need to calculate the absolute value of the angular deviation

Using formula of direction

$\theta=\tan^{-1}(\dfrac{B_{E}}{B_{w}})$

$\theta=\tan^{-1}(\dfrac{20 \mu}{24.4 \mu})$

$\theta=39.3^{\circ}$

Hence, The absolute value of the angular deviation is 39.3°.

The formula we will be using is;F = G m1 m2 / r^2
F earth = 308N
F moon = G me m2 / (81.3 * 0.27^2 RE^2) = 1/5.927 G me m2 / RE^2 = F earth / 5.927 = 52 N is the force of the earth
So the answer in this question is 52 N.
