A boat has a mass of 6800 kg. its engines generate a drive force of 4100 n, due west, while the wind exerts a force of 830 n, du

e east, and the water exerts a resistive force of 1200 n due east. what is the magnitude and direction of the boat's acceleration?

 Let positive be west and negative be east because they are contrasting in directions.

 
The forces are 4100, -830, and -1200

 
The sum of the forces is 4100 – 830 – 1200 = 2070 N. 

Newton’s law F = ma is used. 
2070 = 6800 a 

Isolating a will give us 2070 / 6800 = a

a = 0.34 m/s^2

Design a circuit which takes two inputs and outputs a 1 if and only if the two inputs are the same signal. You may only use two
Ivan

Answer:

Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )

Explanation:

AND gates : only output 1 when both inputs are 1

OR gate:  only output 1 when either or both of the inputs are 1

NOT gates: takes only one input ad output the opposite of the input

The required circuit should takes two inputs and outputs a 1 if and only if the two inputs are the same signal.

The two possible scenarios : both input are 1's or 0's

Q = A ⊕ B = (A AND B) + ( not(A) AND not(B) )

A  B  not(A) not(B)  A AND B    not(A) AND not(B)   Q

0  0     1          1            0                      1                       1

0   1      1         0            0                     0                       0

1    0     0        1             0                     0                       0

1     1     0       0              1                     0                       1

Consider the two electron arrangements for neutral atoms a and b. Are atoms a and b the same element? a - 1s2, 2s2, 2p6, 3s1 b -
Agata [3.3K]

The two neutral atoms A and B have the same number of electrons and atomic number 11. So, the two elements are said to be same.

The electronic configuration of the element is the arrangement of the electrons in the atom of the element in energy levels, orbitals around the nucleus.

The electrons in the atoms of the element with lowest energy are written first before those with higher energy levels. Thus, the electronic configuration shows the electrons in the atoms of the element arranged in order of increasing energies.

The electronic configuration of atoms are given as

A = 1s² 2s² 2p⁶ 3s¹

B = 1s² 2s² 2p⁶ 5s¹

The number of electrons in both the elements is 11. Therefore, their atomic number is also the same i.e, 11. So, both the elements are the same.

To know more about atomic number:
