Answer:

option C

Explanation:

The correct answer is option C.

The ordered pair on distance versus time graph is A particular distance paired with a particular time.

A distance time graph gives the relation between the distance traveled to the time taken to cover the distance.

the area under the velocity time graph gives the distance traveled.

And the slope of the curve gives the acceleration of the body.

If we choose the x-axis to represent time and the y-axis to represent distance, then an (x, y) ordered pair will represent (time, distance). A particular distance paired with a particular time.

Choice C

The ratio of the number of pigs to the number of horse in a farm is 2 to 3 (2:3), if therected are 24 horses, what is the number

pickupchik [31]

Answer:

16 pigs

Explanation:

Let the horses be H.

Let the pigs be P

Let the total number of animals be x.

Given the following data;

Ratio of P to H = 2:3 = 2 + 3 = 5

Number of horses = 24

To find the number of pigs;

First of all, we would determine the total number of animals x.

From the ratio of horse, H:

3/5 * x = 24

Cross-multiplying, we have;

3x = 120

x = 120/3 = 40

Next, we find the number of pigs;

Pigs = 2/5 * 40

Pigs = 80/5 = 16 pigs

Sally walks 10 meters forward and then 5 meters backwards. Which statement most accurate describes the magnitude of her displace

djverab [1.8K]

1. A) Sally's displacement is 5m less than her distance travelled.

Explanation:

- Distance is the total distance travelled by Sally, regardless of her direction. In this case, Sally has travelled 10 meters forward and then 5 meters backward, so the distance travelled is

$d = 10 m + 5 m=15 m$

- Displacement, instead, is the difference between the final position and the initial position of Sally, which means that we have to calculate the vector sum of all the movements made by Sally. Assuming 'forward' as positive direction, this means that Sally's displacement will be:

$d = 10 m +(-5 m)=+5 m$ (forward)

Therefore, we can conclude that Sally's displacement (5 m) is 5 m less than her distance travelled (10 m).

2. B) acceleration due to gravity is always the same

According to Newton's second law:

$F=ma$

by re-arranging it, we find the acceleration of an object:

$a=\frac{F}{m}$ (1)

The only force acting on an object in free fall is the gravity, so $F=mg$ , where m is the mass of the object and g is the acceleration due to gravity. Substituting into (1):

$a=\frac{mg}{m}=g$

So, the acceleration of an object in free fall does not depend on the mass of the object, but only on the value of g, which is the same for every object.

What is the velocity of a beam of electrons that goes undeflected when moving perpendicular to an electric and magnetic fields.

Charra [1.4K]

Explanation:

Given that,

Electric field, E = 7900 V/m

Magnetic field, $B=9.1\times 10^{-3}\ T$

(a) Let v is the velocity of a beam of electrons that goes undeflected when moving perpendicular to an electric and magnetic fields. The magnitude of electric force and the magnetic force balance each other as :

$qE=qvB$
