The maximum length of foil will be 6639.8635 cm or 66.3986 m

To find the maximum length of the foil, the given datas are:

Width of roll of foil = 304 mm

Height or thickness = 0.020 mm

Density of foil = 2.7 g/cm³

Mass of foil = 1.09 Kg

<h3>What is Density?</h3>

Density is the substance's  mass per unit volume. It can be also described by measuring how the particles in the substances tightly packed together.

d = m/ v

v = length (l) × width (w) × height (h)

First of we will convert the Kg into gram and mm into cm.

For 1 Kg = 1000 g

1.09 × 1000 = 1090 g

For 1 cm = 10 mm

304 / 10 = 30.4 cm

0.020 / 10 =  0.0020 cm

Now we will put the values in formula:

d = m/ l× h× w

l = m / d × h× w

l = 1090 g / 2.7 g/cm³× 30.4 cm × 0.0020 cm

l = 1090 g/ 0.16416 g/cm

l = 6639.8635 cm or 66.3986 m

The maximum length of foil will be 6639.8635 cm or 66.3986 m

if you drop a softball from just above your knee, the kinetic energy of the ball just before it hits the ground is about 1 jule,
ipn [44]
False.

The mass of a softball is approximately 200 g (0.2 kg), while the knees are located approximately at 30 cm (0.3 m) from the ground. It means that the gravitational potential energy of the ball when it is dropped is
U=mgh=(0.2 kg)(9.81 m/s^2)(0.3 m)=0.6 J

This corresponds to the total mechanical energy of the ball at the moment it is dropped, because there is no kinetic energy (the ball starts from rest). Then the ball is dropped, and just before it hits the ground, all this energy is converted into kinetic energy: but energy cannot be created, so its final kinetic energy cannot be greater than 0.6 J.

Explanation:

The lamp and the ice bag were at the same place.  

Sounds like the experiment was intended to show on a small scale ocean currents from the poles to the equator and back to the poles. The bag of ice would simulate the cold at the poles while the lamp would simulate the heat provided by the sun near the equator. With that in mind, let's look at the possible flaws and see what is likely.
