Answer: 140 m
Explanation:
Let's begin by stating clear that motiont is the change of position of a body at a certain time. So, during this motion, the balloon will have a trajectory and a displacement, being both different:
The<u> trajectory</u> is <u>the path followed by the body, the distance it travelled</u> (is a scalar quantity).
The displacement is <u>the distance in a straight line between the initial and final position</u> (is a vector quantity).
So, according to this, the distance the balloon traveled during the first 45 s (its trajectory) is 140 m.
But, if we talk about displacement, we have to draw a straight line between the initial position of the balloon (point 0) to its final position (point 90 m). Being its displacement 95 m.
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:
mass and speed determine object's kinetic energy
potential energy is the energy of position
the more mass and height the more potential energy it has
sorry not sure about the others
The new fuse will not blow up when a higher current is flowing and the circuit wont be broken and high current can heat up the object and cause a fire boom
Piston<span> is the part in the combustion engine which moves up and down. Piston is connected in connecting rod which helps to move it.</span>
Spark plugs are used to produce spark.
