Answer:

1) Addition of a catalyst

2) To change the reaction rate of slope B to look like slope A, simply add a catalyst to speed up the rate of reaction, giving you a higher amount of products in a shorter amount of time (line A)

Explanation:

1 and 2)Two things can alter the rate of a reaction, either the addition of a catylist which will not alter the composition of the products or reactants, but will accelerate the reaction time, or an increase in temperature will also increase the rate at which a reaction will occur.

You could choose temperature also and have the same result, it's your choice both are correct, but catalyst is the easiest.

Answer:

Explanation:

1) ½(0.8)t² = 4t

0.4t² = 4t

0.4t = 4

t = 10 s

2) d = vt = 4(10) = 40 m

d = ½atⁿ = ½(0.8)10² = 40 m

3) v = at = 0.8(10) = 8 m/s

In addition to setting a pricing objective, a firm has to look at a number of factors before setting its prices. These factors i

Murljashka [212]

Customers are willing to pay what they think something is worth and don't really care about your costs. If your costs push prices above their perceived value, they simply won't buy. If the perceived value is much higher than your costs, they'll happily pay a price that gives you a huge margin. One of the best examples of this is in retail clothing.

How do base-isolators, the rubber and steel pads under some buildings, reduce earthquake damage?

nika2105 [10]

They absorb the energy of seismic waves.

Explanation:

Base - isolators, rubber and steel pads under buildings reduces earthquake damage by absorbing the energy of seismic waves.

Earthquakes are produced by the sudden release of energy within the earth which causes displacement and sharp movement on earth surface.
There are four main types of waves that are propagated by seismic waves which wrecks havoc.
Understanding the waves and their properties has been useful in designing earthquake resistant structures.
Base-isolators, rubber and steel pads helps to absorb seismic waves.
When seismic waves are absorbed, they are cut off.
This way they cannot cause damage.
