Transform the arithmetic expressions to their equivalent computer expression. F = q (E + v x B)

Explanation
The correct answer is F=q*(E+v*B),F=(Q*(E+V*B)),F=Q*(E+V*B),F=(q*(E+v*B)). This is the correct transformation of the arithmetic expression F = q (E + v x B) into its equivalent computer expression. The expression is multiplied by q and the terms E and v*B are added together inside the parentheses. The variables q, E, v, and B are represented as they are in the original expression.

P1V1=P2V2 Create a formula using computer expression that would compute for the value of V1.

Explanation
The formula V1 = ((P2 * V2) / P1) is the correct answer because it correctly represents the relationship between the initial pressure (P1), initial volume (V1), final pressure (P2), and final volume (V2) as stated in the equation P1V1 = P2V2. By rearranging the equation, we can solve for V1 by multiplying P2 and V2, and then dividing the result by P1. This formula allows us to calculate the initial volume (V1) when the other variables are known.

v = u + at Create a formula using computer expression that would compute for the value of u.

Explanation
The formula u = v - (a*t) is the correct answer. It states that the initial velocity (u) is equal to the final velocity (v) minus the product of acceleration (a) and time (t). This formula is derived from the equation of motion v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time. By rearranging the equation, we can solve for u. Therefore, u = v - (a*t) is the correct formula to compute for the initial velocity.

Pyramid area = b2h/3

Explanation
The given formula for calculating the area of a pyramid is correct. It states that the area of a pyramid is equal to the base squared multiplied by the height, all divided by 3. This formula is derived from the general formula for the volume of a pyramid, which is (1/3) * base * height. Since the area of a pyramid is the base multiplied by the height, dividing by 3 gives us the correct formula for the area.

A>B means that the value of B is greater than the value of A.

True
False

Correct Answer

A. False

Explanation

The given statement "A>B means that the value of B is greater than the value of A" is incorrect. In reality, the symbol ">" represents that the value of A is greater than the value of B. Therefore, the correct answer is False.

Int1==int2 means that the value of variable int1 is equal to the value of variable int2.

True
False

Correct Answer

A. True

Explanation

The statement int1==int2 is a comparison statement that checks if the value of the variable int1 is equal to the value of the variable int2. If the values are indeed equal, the statement will evaluate to true. Therefore, the correct answer is true.

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If A=Z; Z=B does the value of B is 8?

True
False

Correct Answer

A. True

Explanation

The given statement states that A is equal to Z and Z is equal to B. Since A is equal to Z and Z is equal to B, it implies that A is equal to B. Therefore, the value of B is indeed 8.

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If A=B; B=C; C=X; what is the value of J if J=A+B+C?

Correct Answer
30

Explanation
The value of J can be determined by substituting the given values of A, B, and C into the equation J=A+B+C. Since A=B=C=X=30, the value of J is 30.

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If X=B; X=C what is the value of X?

Correct Answer
12

Explanation
The value of X is 12 because it is assigned the value of C, which is 12. Since X is also assigned the value of B, which is 8, the final value of X is the last assignment, which is 12.

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If X=Z; A=X; B=Z what is the J if J=A-B?

Correct Answer
0

Explanation
The value of J is 0 because A is assigned the value of X which is 10, and B is assigned the value of Z which is also 10. Therefore, when we subtract B from A, we get 10 - 10 = 0.

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If B=A; B=C what is the value of A and C? present your answer like this: (a,c)

Correct Answer
(4,12)

Explanation
The given statement B=A and B=C implies that A and C have the same value as B. Since B is equal to 8, the value of A and C would also be 8. Therefore, the correct answer is (8, 8).

Solve the problem statements : Given: X=10; Y=20 ; Z=30; A=4; B=8; C=12 If A=X; B=Y, what is the value of J if J=X+Y?

Correct Answer
30

Explanation
Since A is equal to X and B is equal to Y, we can substitute the values of X and Y into the equation J = X + Y. Therefore, J = 10 + 20 = 30.
