Trade winds are found ________.

1 answer:

5 0

Selection (b) is the best answer. These are the winds found between the 25-degree north and south latitudes, converging at the doldrums just north of the equator. They have been used for centuries to navigate much more quickly around the oceans.

An astronaut has a mass of 100 kg and has a weight and if 370 N on Mars. What is the gravitational strength on Mars?

Reika [66]

Answer:

3.7 N/kg

Explanation:

The gravitational strength refers to the amount of gravity acting per unit mass. Hence in this case,

Gravitational Strength = Weight / Mass

= 370 / 100

= 3.7N/kg

The De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°

<h3>How is the De broglie wavelength of a thermal neutron at room temperature calculated?</h3>

Temperature, T = 300K

Momentum, p = mv

Therefore v = p/m

Energy, E= 1/2 m( p/m) ²

Boltzman Energy= 3/2 KT

3/2KT = 1/2 m(p/m)²

Therefore p = $\sqrt{3RTm}$

According to De broglie hypothesis, P = h ÷ λ

Therefore, λ = h ÷ $\sqrt{3RTm}$

= 6.6× $10^{-34}$ ÷ $\sqrt{3 \times 1.38 \times 10^{-23} \times 300 \times 1.6 \times 10^{-27} }$

= 0.15 × $10^{-9}$

Therefore the De broglie wavelength of a thermal neutron at room temperature 300K = 1.5 × A°

What are the factors affect the Electric forces between two charges and What is the relationship between each factor and the Ele

Cloud [144]

Explanation:

If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the

• Magnitude if each charge, q1 and q2

• Sign of each charge (+ or -)

• Distance between the charges, r

This is essentially Coulomb’s Law:

FE = (kq1q2)/r2

For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
