Answer:
1 COSMETICS WITH MICROBEADS
2 COFFEE CAPSULES
3 WET WIPES
Explanation:
1.Plastic microbeads began to be introduced in cosmetics, toiletries and cleaning products in the 1970s, but it wasn’t until the 1990s that brands began to incorporate them in a massive way. Toothpastes, creams, lotions, shampoos and detergents began to include microbeads as the great innovation of the time for achieving an abrasive effect, replacing the nature-based materials in use until then.
2 Capsule coffee machines have revolutionized the breakfasts of millions of people, offering a convenient and practical option for preparing an espresso or latte with the same quality one finds in a café. Data from 2017 indicate that 29% of US coffee consumers use these machines, a figure that continues to grow.
3They started off being an invaluable aid for fathers and mothers when facing the messy moment of their baby’s diaper change, but soon they began to be reinvented as deodorants, cleansers, disinfectants and hand soap substitutes, and even as toilet paper for adults. Wet wipes have become a common item in many homes, but with a dramatic consequence: they help to create fatbergs, immense accumulations that block the sewerage networks and that are composed of 93% non-degradable wipes, together with fat, condoms and other similar items thrown into the toilet.
Answer: 107g
Explanation:
Just subtract 125 from 232, like this: 232-125=107g.
Answer:
Mass of the other object is 38.45 kg.
Explanation:
Given:
The gravitational force between two objects is, 
N
Mass of one object is, 
Distance between the objects is, 
Gravitational constant is, 
Let the mass of the other object be 
Gravitational force is given as:
Plug in the given values and solve for 
. This gives,
Therefore, the mass of the other object is 38.45 kg.
Answer:
-17.8 V
Explanation:
The induced emf in a coil is given as:
where N = number of loops
dB = change in magnetic field
r = radius of coil
dt = elapsed time
From the question:
N = 50
dB = final magnetic field - initial magnetic field
dB = 0.35 - 0.10 = 0.25 T
r = 3 cm
dt = 2 ms = 0.002 secs
Therefore, the induced emf is:
Note: The negative sign implies that the EMf acts in an opposite direction to the change in magnetic flux.
The focal length would likely decrease as the refractive index and the increase when the curvature radius of the lens increases. The decrease in focal length happens since a higher index of refraction would signify that the rays of the sun striking to an object would tend to bend more.
