Based on the information in the table, which two elements are most likely in the same group, and why? bismuth and thallium, beca

use their atomic masses are very similar nitrogen and oxygen, because they were both first isolated in the same year sodium and thallium, because their names both end in the same suffix: -ium bismuth and nitrogen, because they have the same number of valence electrons

The answer would be Bismuth and Nitrogen because they have the same number of valence electrons.

Groups in the periodic table are arranged in columns. When it comes to neutral atoms, the number of valence electrons it has is equal to the main group of that element. For example, Bismuth is under group 5A of the periodic table. It has 5 valence electrons. If you look for Nitrogen in the periodic table, you will find it in Group 5A as well and this means that it also has 5 valence electrons.

What is the force applied to a baseball that has a mass of 142kg and has a acceleration of 30m/s to the power of 2
aev [14]
  • Mass=m=142kg
  • Acceleration=a=30m/s
  • Force=F

Using Newton's second law

\\ \sf\Rrightarrow F=ma

\\ \sf\Rrightarrow F=142(30)

\\ \sf\Rrightarrow F=4260N

Orlov [11]

The number converted is 0.0467 \frac{(kg)(s)}{m^3}

Explanation:

In order to convert from the original units to the final units, we have to keep in mind the following conversion factors:

1 kg = 1000 g = 10^6 mg

1 min = 60 s

1 m^3 = 1000 L

The original unit that we have is

\frac{mg\cdot min}{L}

Therefore, it can be rewritten as:

=\frac{mg \frac{1}{10^6 mg/kg}\cdot min\cdot  60 s/min}{L\frac{1}{1000L/m^3}}=0.06 \frac{(kg)(s)}{m^3}

Therefore, since the initial number was 0.779, the final value is

0.779\cdot 0.06 \frac{(kg)(s)}{m^3}=0.0467 \frac{(kg)(s)}{m^3}

How can you justify that force is transferred to lift and throw soil using shovel?<br>​
Natali [406]

Forces are needed to lift, turn, move, open, close, push, pull, and so on. When you throw a ball, you are using force to make the ball move through the air. More than one force can act on an object at the same time.
