Answer:As the Sun moves throughout the day, some plants can follow it. This is called <u><em>solar tracking.</em></u>
Explanation:
There are flower which tracks the position sun are called heliotropism or solar tracking. flowers.These are the flower which face their bloom side towards the sun to maximize the photosynthesis.The most common example of this is Sun flower.
Work done can be computed using the formula:

Where:
W = work (J)
F = Force (N)
d = Distance (d)
Looking at the given, you know that you do not have a value for force, so you will have to solve for it.

Where:
F = Force
m = mass
a = acceleration
Because the object is being lifted, the acceleration will rely on gravity. Acceleration due to gravity is a constant 9.8 m/s^2. Let's list our given first:
F = ?
m = 100kg
a = 9.8m/s^2
Put that into our equation and solve:



Our force is then
980 N.
Now that we have force we can solve for Work. The given for work is as follows:
F= 980N
d = 1.4m
Put that into our formula and solve:



The work done is
1,372J.
Answer: Infrared radiation
Explanation:
Infrared radiation is not visible to the human eye, since its wavelengths are outside the visible spectrum (between 700 nm and 1 mm), however this type of electromagnetic radiation is detected by the human body as heat.
These waves can be divided into:
- Near infrared or long wave infrared: it is the least sensitive to color and is easily absorbed by water.
- Medium or medium wave infrared: it is also insensitive to color and easily absorbed by water and many types of plastics and paints.
- Far infrared or short wave infrared: it is more penetrating than the long wave and is good for heating metals, these waves also can pass through clear materials. This light has many uses, including heating lamps in physiotherapy and medical treatments, heat sensing devices, among others.
Scissors and a pen that is the answer
Answer:
A vibration is a repeated back-and-forth or up-and-down motion.
Explanation:
Waves carry energy through empty space or through a medium without transporting matter.
