Two velocity vectors, one is twice of the other, and separated by 90 Degree angle. If their resultant is calculated 90 m/s, what
Artyom0805 [142]

Answer:

Vy = 80.5 [m/s]

Explanation:

In order to solve this problem we must use the Pythagorean theorem.

V = 90 [m/s]

The components are Vx and Vy:

Therefore:

v=\sqrt{v_{x}^{2} + v_{y}^{2}   }

where:

Vy = 2*Vx ; because one is twice of the other.

90 = \sqrt{v_{x}^{2}  +(2*v_{x})^{2} }\\ 90 =\sqrt{v_{x}^{2}+4*v_{x}^{2}} \\90 =\sqrt{5v_{x}^{2}} \\90=2.23*v_{x} \\v_{x}=40.25[m/s]

and the bigger vector is:

Vy = 40.25*2

Vy = 80.5 [m/s]

How do low energy electromagnetic waves compare with high energy electromagnetic waves? Select all
Dennis_Churaev [7]

Answer:

Explanation:

The different types of radiation are defined by the the amount of energy found in the photons. Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays

The distance to the other planets in the Solar System from the Earth depends on where they are in their orbit. The closest that
Afina-wow [57]

Answer:

3.6 arcsec

Explanation:

 angular diameter = diameter / distance

diameter is constant

so angular diameter ∝ 1 / distance

angular diameter = k / distance

For first case ,

18 = k / .5

for second case let angular diameter be D .

D = k / 2.5

dividing ,

D / 18 = .5 / 2.5 = 1 / 5

D = 18 / 5 = 3.6 arcsec

3.6 arcsec is the answer .

How does Newton's law of motion describe when and how objects move?
r-ruslan [8.4K]
Newton's laws of motion relate an object's motion to the forces acting on it. ... In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
