Answer:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

Your answer should be:

1. Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.

If you’re not changing your speed and you’re not changing your direction, then you simply cannot be accelerating—no matter how fast you’re going. So, a jet moving with a constant velocity at 800 miles per hour along a straight line has zero acceleration, even though the jet is moving really fast, since the velocity isn’t changing. When the jet lands and quickly comes to a stop, it will have acceleration since it’s slowing down.

2. True (Because if you subtract the final speed to the initial speed, you can see how much acceleration you put on or took off.

lesya [120]

<u>Answer:</u> The correct answer is Option b.

<u>Explanation:</u>

The expression of elevation in boiling point is given as:

\Delta T_b=i\times k_b\times m

where,

\Delta T_b = Elevation in boiling point

i = Van't Hoff factor  

T_b = change in boiling point

k_b = boiling point constant

m = molality

For the given options:

<u>Option 1:</u>  0.100 m NaNO_3

Value of i = 2

So, molal concentration will be = (0.100)\times 2=0.200m

<u>Option 2:</u>  0.100 m Li_2SO_4

Value of i = 3

So, molal concentration will be = (0.100)\times 3=0.300m

<u>Option 3:</u>  0.200 m C_3H_8O_3

Value of i = 1  (for non-electrolytes)

So, molal concentration will be = (0.200)\times 1=0.200m

<u>Option 4:</u>  0.060 m Na_3PO_4

Value of i = 4

So, molal concentration will be = (0.060)\times 4=0.24m

As, the molal concentration of Li_2SO_4 is the highest, so its boiling point will be the highest.

Thus, the order of increasing boiling points follows:

NaNO_3=C_3H_8O_3

Hence, the correct answer is Option b.

Vedmedyk [2.9K]

Answer:

D

Explanation:

beacause all the elements in period 3 has different valence electrons hence you look at the first element in period 3 is sodium which has a valence electron of 1 when you go across the period to the right their valence electron decreases to be negative
