Yes, they are also known as white rainbows or lunar rainbows.
Answer:
An image is formed on the retina with light rays converging most at the cornea and upon entering and exiting the lens. Rays from the top and bottom of the object are traced and produce an inverted real image on the retina. The distance to the object is drawn smaller than scale
The astronaut would go the opposite direction due to Newton’s third law of -10N, -10N, -9N, -9N
Let me know if this helped you, please rank this was the brainlist answer if possible, thanks!
This is a perfect problem to use positive and negative velocities.
Let's call the positive direction the direction that points UP.
Then the negative direction is the one that points down.
The acceleration of gravity on Earth is 9.8 m/s² down. That means
that any object with no forces on it except gravity gains 9.8 m/s of
speed downward every second.
OK. Ready to go to work:
The ball's initial velocity is +(up)20.0 m/s .
Every second after the toss, the ball has -(down)9.8 m/s more velocity.
The ball's velocity after 3 seconds is
+20 + 3(-9.8) =
20 - 29.4 = - 9.4 m/s .
That means it's velocity at that time is 9.4 m/s pointing down.
Answer:
1.69 T
Explanation:
Applying,
F = BvqsinФ.................. Equation 1
Where F = Force, B = magnetic field, v = velocity, q = charge on an electron, Ф = angle between the electron and the field.
make B the subject of the equation,
B = F/(vqsinФ)............. Equation 2
From the question,
Given: F = 2.0×10⁻¹³ N, v = 7.4×10⁵ m/s, Ф = 90°
Constant: q = 1.60×10⁻¹⁹ C
Substitute into equation 2
B = 2.0×10⁻¹³/(7.4×10⁵×1.60×10⁻¹⁹×sin90°)
B = 0.169×10
B = 1.69 T
