The work w done when lifting an object varies jointly with the object's mass m and the height h that the object is lifted. the w
Galina-37 [17]
Work done can be computed using the formula:

W=Fd

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. 

F = ma

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:
F=ma
F=(100kg)(9.8m/s^{2})
F=980kg.m/s^{2}

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:
W = Fd
W = (980N)(1.4m)
W = 1,372J

The work done is 1,372J.

Which one of the above forms of em radiation does our body detect as heat?
Maru [420]

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.
