Answer:
6kg m/s
Explanation:
Momentum = p=mxv
Momentum = mass x velocity
4kg x 1.5m= 6 kg m/s
Answer:
I know only one type of light that is absorbed by genetic materail and that is UV light
Explanation:
The tensions in the wires at the given angle of inclination is determined as 434.1 N.
<h3>
Tension on the wire</h3>
The tension in the wires is calculated as follows;
T = Wsinθ
where;
- T is tension in each wire
- W is weight of the traffic light
T = 2500 x sin(10)
T = 434.1 N
Thus, the tensions in the wires at the given angle of inclination is determined as 434.1 N.

Answer:
No, according to Newton's first law of motion, the block cannot exert a force on itself, and the body will remain at rest unless unbalanced forces act on it
However according to Newton's third and first laws of motion the action of gravity pulling the block down the plane is equal to the reaction force of friction, preventing the motion
Explanation:
According to Newton's third law, the action force of gravity on the block tending to drag the block down along the inclined plane is equal to the reaction force of the frictional force of the inclined plane due to the interactions between the surfaces of the block and the plane which tends to prevent the motion of the block when both the component of the gravitational force down the plane and the frictional force are equal.
Answer:
A) color
Explanation:
Visible light is a portion of the electromagnetic spectrum, that includes wavelengths approximately from 380 nm to 750 nm.
It is the only part of the electromagnetic spectrum that the human eye can see. Depending on the wavelength of the light in this region, we perceive the light as a different color.
Therefore, each color is associated to a different range of wavelength, as follows:
Violet 380 - 450 nm
Blue 450 - 495 nm
Green 495 - 570 nm
Yellow 570 - 590 nm
Orange 590 - 620 nm
Red 620 - 750 nm
