Answer:

The correct answer is Option A (decrease).

Explanation:

  • According to Heisenberg's presumption of unpredictability, it's impossible to ascertain a quantum state viewpoint as well as momentum throughout tandem.
  • Also, unless we have accurate estimations throughout the situation, we will have a decreased consistency throughout the velocity as well as vice versa though too.

Other given choices are not connected to the given query. Thus the above is the right answer.

Answer:

Part 1: 0.3789

Part 2: 746 J

Part 3: 2.162 kW

Explanation:

Part 1:

Eff=  1-\frac{1223}{1969}

Eff= 0.378873 ≈ 0/3789

Part 2:

W= 0.3789(1969)

W= 746 J

Part 3:

Power=\frac{W}{t}

Power= \frac{746}{0.345}

Power= 2162.3188 Watts

2162.3188 W-----> 2.162 kW

Which element could provide one atom to make an ionic bond with nitrogen?​
aev [14]

Answer:

boron

aluminum

gallium

indium

thallium

Explanation:

Any of these could work. Nitrogen has 5 valence electrons so you just needed to pick an element that has 3 valence electrons that nitrogen could borrow. This periodic table shows valence electron counts:

When running a 100 meter race Donald reaches his maximum speed when he is 40 meters from the starting line, and 7 seconds have e
Slav-nsk [51]

Answer:

Part a)

v_{max} = 7 m/s

Part b)

d = 7 \times 3 = 21 m

Part c)

d = 61 m

Part d)

d = 50.5 m

Explanation:

As we know that he start from rest and moves with uniform acceleration

so here we can say that

d = v\Delta t

as we know here that he move with uniform speed from t = 7 to t = 11

So we will have

68 - 40 = v(11 - 7)

28 = 4 v

v_{max} = 7 m/s

Part b)

If Donald runs for 3 s after reaching his maximum speed

So here distance moved by Donald

d = v t

d = 7 \times 3 = 21 m

Part c)

Distance of Donald from start line is given as

d = 40 + 21

d = 61 m

Part d)

Distance from start line after t = 8.5 s

d = 40 + vt

d = 40 + (7)(1.5)

d = 50.5 m
