The two laboratory equipment in the picture are beaker and chemicals.The people in the picture are not wearing any protective gears while (a) working in the laboratory (b) Throwing the chemicals on the floor.

Among the many items that would be considered general lab equipment are pipettes, scales, centrifuges, Bunsen burners, freezers, hot plates, incubators, coolers, stirrers, water baths, and fume hoods

The dangers of working in a laboratory setting include:

Chemical hazards: Handling toxic substances can cause irritation and carcinogenicity.

Biological hazards: Biological hazards include hazards from working with small animals, working with blood borne pathogens and working with biological agents, such as viruses and bacteria.

Physical hazards: Physical hazards include exposure to noise, poor posture and the explosibility and flammability of substances.

Safety hazards: Safety hazards include unbalanced centrifuges, danger when handling hot sterilized items and electrical hazards, such as shock, explosions, blasts and electrocutions.

Allergy hazards: A common allergy hazard in the laboratory setting is a latex allergy, as many of the materials used in a laboratory setting are latex.

Question 3
wariber [46]

Answer:

1200J

21.8Watts

Explanation:

Given parameters:

Force  = 400N

Distance  = 3m

Time  = 55s

Unknown:

Work done  = ?

Power  = ?

Solution:

Work done is the force applied to move a body through a certain distance.

Power is the rate at which work is done

 Work done  = Force x distance  = 400 x 3 = 1200J

Power  = \frac{work done }{time}   = \frac{1200}{55}    = 21.8Watts

An 86.0-kg climber is scaling the vertical wall of a mountain. His safety rope is made of nylon that, when stretched, behaves li
Brrunno [24]

Answer:

x = 1.95 m

Explanation:

As we know that total mechanical energy is conserved here

So gravitational potential energy of the climber will convert into spring potential energy

So we will have

mg(L + x) = \frac{1}{2}kx^2

here we know that

m = 86 kg

L = 0.750 m

k = 1.20 \times 10^3 N/m

now we will have

86\times 9.8(0.750 + x) = \frac{1}{2}(1.20 \times 10^3) x^2

0.750 + x = 0.71 x^2

x = 1.95 m

What is the difference in the positioning of the Sun, Earth and moon for a lunar eclipse versus a full moon?
Lady bird [3.3K]

When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.
