Bill was really bored at work. During his break, he decided to check his carotid artery. He placed both fingers on his neck and

contacted his pulse. He counted for 20 seconds. In those 20 seconds, Bill had a total of 24 beats. What is Bill's BPM?

Answer:

72 beats per minute

Explanation:

Heart beat causes the flow of blood round the body. This heart beat can be felt as pulse in the wrist or neck carotid artery. The heart rate which is measured in beats per minute (BPM) is used to determine the number of heart beats per minute.

You can calculate your BPM using the carotid artery found in the neck close to the windpipe.

Given that for 20 seconds, Bill had a total of 24 beats.

60 seconds = 1 minute.

Hence,  Bill's BPM = (24 beats per 20 seconds) * (60 seconds per minute) = 72 beats per minute

The sides of a cube are each of length 1. 00 m. Each side is measured with an uncertainty
astraxan [27]

The absolute uncertainty in the volume of the cube is 0.06 m³.

We need to know about the uncertainty of measurement to solve this problem. The uncertainty of cube volume can be determined by

V = s³

|ΔV| = dV/ds x Δs

where V is volume, s is length, ΔV is uncertainty in the volume and Δs is the uncertainty of length.

From the question above, we know that

s = 1.00 m

Δs = 2% of s = 2/100 x 1 = 0.02 m

By using the uncertainty of volume formula, we get

|ΔV| = dV/ds x Δs

|ΔV| = d(s³)/ds x Δs

|ΔV| = 3s² x Δs

|ΔV| = 3. 1² x 0.02

|ΔV| = 0.06 m³

Hence, the uncertainty in the volume is 0.06 m³.

Alice kicks a 0. 25 kg soccer ball with 0. 5 N of force. What force does the ball exert on Alice’s foot as she kicks it? N.
leva [86]

The force exerted on Alice’s foot as she kicks the ball is 1.25 N.Force can be defined as the influence that can accelerate the object.

<h3>What is force?</h3>

Force can be defined as the influence that can accelerate the object. From Newton's Second Law of motion,

F = ma

Where,

F - force

m - mass = 0. 25 kg

a - acceleration = 5 N

Put the values in the formula,

F = 0.25 \times 5\\\\F = 1.25 \rm \ N

Therefore, the force exerted on Alice’s foot as she kicks the ball is 1.25 N.
