Moving or transportation tools, equipment and methods provides guidance

on the safe an efficient ways to move items.

The correct responses are;

1) (B); 2) B; 3) C; 4) A; 5) D; 6) B; 7) A; 8) B; 9) (A); 10) A; 11) C; 12) B; 13) A; 14) A; 15) B; 16) A; 17) B; 18) A; 19) (C); 20) B; 21) B; 22) A; 23) B; 24) (C); 25) B

Reasons:

1) The correct option is; (B) Withstand a heavier load and add greater stability

By sing two wheels on the rear of a truck, heavy loads can be hauled, and transported around corners, and bumpy roads, reducing the possibility of the load tipping the truck over, thereby keeping the truck stable.

2) The correct option is; B

The Phillips-head screw is cross shaped, and required a cross shaped screwdriver, which is option B)

3) The correct option is; C

The alternator converts mechanical rotational energy into electrical energy, and usually has a compact electrical coil and magnets within its enclosure. The alternator is option C

4) The correct option is; A

The rear of a truck moves in the direction the front tires are turned

5) The correct option is; D

Option A and B are pliers, while option B is a spanner, all of which are used to fasten and loosen bolts and nuts. Option D is a screwdriver used to fasten and loosen screws.

6) The correct option is; B

The working platform on scaffold B has extra support from the diagonal braces.

7) The correct option is; A

The large size tires in refrigerator A increases the contact surface with the road to prevent entering into small holes

8) The correct option is; B

Due to the heavier load in the trailer of pick-up truck B, more force is required, to stop the truck according to Newton's Laws of motion, and therefore, a longer distance will be taken to stop by the truck, given similar conditions (magnitude) stopping force available

9) The correct option is; (A)

Jumping two batteries to start an automotive with a dead battery requires a Negative to Negative / Positive to Positive connection, which is option (A)

10) The correct option is; A

The air filter will have a open outer rim for the free passage of air.

11) The correct option is; C

The scale measures the difference in weight, and the weight depends on the mass of the item. Given that the mass are equal, both weights would be equal, and therefore, the scale would be level.

12) The correct option is; B

The smoothest ride is closest to the most weight of the vehicle, which is located in the front, therefore, the area that gets the smoothest ride is option B

13) The correct option is; A

The downward pressure is given by the location of the load relative to the wheel on the trailer, that gives either a clockwise or downward moment of force when in position of option A or a counterclockwise or upward moment at B

14) The correct option is; A

Gear connected by belt or chain move in the same direction, therefore, the direction of wheel 3 is option A

15) The correct option is; B

A tire blowout will not occur because, the pressure is below the recommended pressure. However, the motion of the car will be unstable

16) The correct option is; A

When tightening a nut with an adjustable wrench, the direction of turning the wrench is towards the movable jaw, therefore, the option A is correct

17) The correct option is; B

The difference between the threads of the given tires is the depth of their grooves, therefore, the tire in option B has more thread.

18) The correct option is; A

When loading items on a trailer, the majority of the load should be located in the front, therefore, the correct location for loading only the washer is illustrated by the picture A.

19) The correct option is; (C)

The object has a lead, an insulated handle, and a electrical bulb that lights up when there is electricity, therefore, it is used for (C) Checking for electrical current travelling through a wire.

20) The correct option is; B

The trailer swings in the opposite direction to the truck.

21) The correct option is; B

The ladder in picture B is safer because it spreads more at the base

22) The correct option is; A

Most of the weight of the refrigerator act on the wheel in picture A than in picture B

23) The correct option is; B

The gear turns towards the screen on the left and away from the screen on the right, which is a direction from left to right.

24) The correct option is; (C)

The cotter pin is assembled last to hold the bolt in place, and cannot be assembled before the other parts as it will restrict their movement

25) The correct option is; B

The front tire should be turned in the opposite direction to the intended direction of the trailer.

toThePowerOf is a method that accepts two int arguments and returns the value of the first parameter raised to the power of the

inessss [21]

Answer:

cubeVolume = toThePowerOf(cubeSide, 3)

Explanation:

The function toThePowerOf, receives two int arguments say, a and b, where a is the first argument and b is the second argument as follows:

toThePowerOf(a,b)

The function returns the first argument(a) raised to the power of the second argument (b) i.e a ^ b as follows:

toThePowerOf(a, b){

return a^b

}

In the call to the function, the first argument a, is replaced with the variable cubeSide and the second argument b is replaced with the value 3.

Hence, the returned result becomes cubeSide ^ 3 which is then stored in a variable cubeVolume as follows:

cubeVolume = toThePowerOf(cubeSide, 3)

Write a program that generates two 3x3 matrices, A and B, withrandom values in the range [1, 100] and calculates the expression½

Alex

Answer:

#include <bits/stdc++.h>

using namespace std;

int main() {

int A[3][3],B[3][3],res[3][3],i,j;

srand(time(0));//for seed.

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

int val=rand()%100+1;//generating random values in range 1 to 100.

int val2=rand()%100+1;

A[i][j]=val;

B[i][j]=val2;

}

cout<<endl;

}

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

res[i][j]=0.5*A[i][j]+3*B[i][j];//storing the result in matrix res.

}

cout<<"Matrix A is"<<endl;

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

cout<<A[i][j]<<" ";//printing matrix A..

}

cout<<endl;

}

cout<<"Matrix B is"<<endl;

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

cout<<B[i][j]<<" ";//printing matrix B..

}

cout<<endl;

}

cout<<"The result is"<<endl;

for(i=0;i<3;i++)

{

for(j=0;j<3;j++)

{

cout<<res[i][j]<<" ";//printing the result..

}

cout<<endl;

}

return 0;

}

Output:-

Matrix A is

13 95 83

88 7 14

24 22 100

Matrix B is

11 13 95

48 35 20

68 100 18

The result is

39.5 86.5 326.5

188 108.5 67

216 311 104

Explanation:

I have created 2 matrices A and B and storing random numbers int the matrices A and B.Then after that storing the result in res matrix of type double to store decimal values also.Then printing the res matrix.

Phoebe has to give a presentation about recycling. Where should she look while presenting?

Naddika [18.5K]

Well, I think that maybe the answer is B or C. She shouldn't only look at her presentation while she is presenting it, that doesn't look professional, and you want to look at the people you are talking to.
