The image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.

<h3>What is a vector quantity?</h3>

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

Thus, the image shows the correct way of lining up vectors to add them together, that the two arrows lined up one after the other, therefore the correct answer is option B.

A 1056-hertz tuning fork is sounded at the same time a piano note is struck. You hear three beats per second. What is the freque
REY [17]

Answer:

f_2 = 1053 Hz

or

f_2 = 1059 Hz

Explanation:

As we know that the beat frequency is given as

|f_1 - f_2| = f_{beat}

here we know that

f_1 = 1056 Hz

f_{beat} = 3 Hz

now we have

|1056 - f_2| = 3

now we have

1056 - f_2 = \pm 3

so we have

f_2 = 1053 Hz

or

f_2 = 1059 Hz

A bowling ball weighing 71.2 N is attached to the ceiling by a 3.70 m rope. The ball is pulled to one side and released; it then
amm1812

Answer:

a, 7.26kg

b, 36.59N

Explanation:

The question says it swings like a pendulum, as such, we would use the formula for circular acceleration.

a = v²/r

a = 4.2²/3.7

a = 17.64/3.7

a = 4.77m/s²

The acceleration of the ball is directed towards the centre because circular acceleration is usually directed towards the centre

To find tension, recall, F = ma

m = F/a

m = 71.2/9.81

m = 7.26kg

In solving for tension then, we use our acceleration to be (9.81 - 4.77) = 5.04m/s²

Tension = ma

Tension = 7.26 * 5.04

Tension = 36.5904

Hence the tension in the rope is 36.59N
