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.

Ivan

Answer:

The statement is true: velocity and acceleration have opposite directions in the interval of braking.

Explanation:

Let's say we have a velocity v>0.

The acceleration a is the rate of change of the velocity v. This means that if v is <em>increasing during</em> time, then a must be positive. But if v is <em>decreasing over</em> time, then a will be negative (even though the velocity is positive).

Mathematically:

a=\frac{dv}{dt}

v decreases ⇒\frac{dv}{dt}

⇒a.

Example:

v(t)=e^{-t}>0 \\\\\frac{dv}{dt}=-te^{-t}

bazaltina [42]

The answer is; C

In particular points in the earth’s surface, underground water is naturally heated to steam that can be harness for geothermal energy. The steam that ejects from the ground with high kinetic energy can be used to turn turbines that generate electricity. The underground water is usually heated by the hot rocks beneath that are subjected to the immense heat of magma or the enormous pressure of overlying crust.
