They’re falling toward earth & moving forward at about the same velocity. because the downward and forward forces are nearly equal, the astronauts are not pulled in any specific direction, so they float . <span>

1). Yes. An object can be moving if the net force acting on the object is zero.
A non-zero net force is required to CHANGE the object's motion ... speed it up,
slow it down, or change its direction. But no force is required to keep it moving
at a constant speed in a straight line.
2).a). The motion of the box changes, from not moving to moving.
So the forces acting on it must be unbalanced.
2).b). The motion of the box doesn't change. It goes from not moving
to still not moving. So the forces acting on it must be balanced.
2).c). The motion of the box changes. Its speed decreases.
So the forces acting on it must be unbalanced.
Answer:
Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, between the infrared and the ultraviolet.
Here are the 7 from shortest to longest wavelength.
Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
Indigo - 420 - 440 nm.
Blue - 440 - 490 nm.
Green - 490 - 570 nm.
Yellow - 570 - 585 nm.
Orange - 585 - 620 nm.
Red - longest wavelength, at around 620 - 780 nanometers with lowest frequency.
Explanation:
Answer:
Ohms law state that the current I flowing through a metallic conductor is directly proportional to the potential difference V across its end, provided that all physical condition are kept constant i.e temperature
Explanation:
that is, V varies directly to I
Where,
V= potential difference in volt and
I = current in Ampere (A)
therefore,
V= IR and R is measured in ohm
