The smaller the mass of an object, the _____ its inertia

Answers

Answer:

larger

Explanation:

just trust me

The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object

What is inertia?

The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.

Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.

Answer:

A. The path of least resistance.

Explanation:

ur welcome again ;)

An electric current will always follow the path of least resistance. So, the right option is a.

In inverse relation to the resistance of the pathways, electric current follows every available paths.

The voltage and resistance of the path in the electric circuit affect the amount of electric current that flows through the circuit.

The quantity of electric current flowing through the circuit is inversely proportional to the resistance in the circuit.

Assuming a fixed voltage, the current increases with decreasing resistance. The current decreases in accordance to the level of increasing resistance.

Answer:

1. 5 V

2. A₂ = 1.2 A

Explanation:

1. Determination of the voltage measured at R₃.

Voltage at R₁ (V₁) = 1 V

Voltage at R₂ (V₂) = 6 V

Total voltage (Vₜ) = 12 V

Voltage at R₃ (V₃) =.?

Vₜ = V₁ + V₂ + V₃

12 = 1 + 6 + V₃

12 = 7 + V₃

Collect like terms

12 – 7 = V₃

V₃ = 5 V

Thus, the voltage measured at R₃ is 5 V

2. Determination of A₂.

From the circuit diagram, we can see that the resistors are in series arrangement. This means that the same current will pass through each resistor.

Thus,

A₂ = A₁ = 1.2 A

Australian Tiger beetles can travel 2.5 m/s. How long would it take a tiger beetle to run the length of a standard football field (109.7 m)?

Answers

Answer:

Time = 43.88 seconds

Explanation:

Given the following data;

Speed = 2.5 m/s

Distance = 109.7 m

To find the time it would take to run the length of a standard football field, we would use the following formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making time the subject of formula, we have;

[tex]Time = \frac{distance}{speed}[/tex]

Substituting into the formula, we have;

[tex]Time = \frac{109.7}{2.5}[/tex]

Time = 43.88 seconds

Therefore, it would take a tiger beetle 43.88 seconds to run the length of a standard football.

$

,
600
$20,600?

Answers

Answer:

8.5

Explanation:

To the nearest tenth of a year, it would take around 9.1 years when calculate compoundly for the account's worth to reach $20,600.

What is Compound interest?

A loan or investment's initial principal as well as any accrued interest from earlier periods are both taken into account when calculating compound interest.

To resolve this issue, we can apply the compound interest formula:

A = P(1 + r/n)nt

where:

A represents the balance of the account after t years.P stands for the initial outlay ($8,900 in this case).The annual interest rate is r, which is unknown.The number n determines how often interest is compounded each year (in this case, once every seven years because the value of the money doubles every seven years).The number of years is t.

When A = $20,600, we need to determine t. Since we are aware that the initial investment would double after seven years, we can use the following formula to determine the yearly interest rate:

2 = (1 + r/n)^(nt)

If n is 1/7 (since the investment twice once every 7 years), 2 is the factor by which the investment doubles, and t is an unknown.

When we simplify this equation, we obtain:

t log(1 + r/7) = log(2)

When we solve for r, we get:

r = 7[(2^(1/t))-1]

Now that we have P, r, n, and A, we can enter them into the compound interest formula to find t:

$20,600 = $8,900(1 + r/1)^(1t)

2.318 = (1 + r)^t = log (2.318) / log (one plus r)

t is equal to log(2.318)/log(1 + 7[(2(1/t))-1]).

We can iteratively solve for t using a calculator, beginning with a first guess of 7 years (because the investment doubles every 7 years):

r = 0.0998 and A = $17,800 for t = 7 years

r = 0.0909 and A = $19,397 for t = 8 years.

r = 0.0833 and A = $20,416 for t = 9 years.

r = 0.0823 and A = $20,601 (closest to $20,600) for t = 9.1 years

As a result, it would take the account's value to reach $20,600 in around 9.1 years (to the nearest tenth of a year).

Therefore, when calculated compoundly, it would take approximately 9.1 years for the account's value to reach $20,600, to the nearest tenth of a year.

One type of slingshot can be made from a length of rope and a leather pocket for holding the stone. The stone can be thrown by whirling it rapidly in a horizontal circle and releasing it at the right moment. Such a slingshot is used to throw a stone from the edge of a cliff, the point of release being 25.6 m above the base of the cliff. The stone lands on the ground below the cliff at a point X. The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle on which the stone is whirled. Determine the angular speed of the stone at the moment of release

Answers

Answer:

the angular speed of the stone at the moment of release is 15.05 rad/s

Explanation:

Given the data in the question;

The point of release ( height ) h = 25.6 m

the time of the fall of the stone will be;

⇒√( 2h/g )

we know that g = 9.81 m/s

so we substitute

t = √( (2 × 25.6 m) / 9.81 m/s )

t = √( 51.2 / 9.81 m/s )

t = √( 5.219164 s )

t = 2.285 s

Now, let v represent velocity at the time of release

them v × t ~ v × 2.285 s is the horizontal distance traveled.

Given that; The horizontal distance of point X from the base of the cliff (directly beneath the point of release) is 34.4 times the radius of the circle.

so

v × 2.285 = 34.4 × radius

Now, if the angular speed is ω then velocity at the time of release will be;

v = radius × ω

hence;

(radius × ω)  × 2.285 = 34.4 × radius

radius cancels each other out and we have;

ω  × 2.285 = 34.4

ω = 34.4 / 2.285

ω = 15.05 rad/s

Therefore, the angular speed of the stone at the moment of release is 15.05 rad/s

10. A jogger runs along a road for a distance of 2700 m. If it takes her 900 seconds
to run that distance, what is her speed?

Answers

Answer:

Speed = 3 m/s

Explanation:

Given the following data;

Distance = 2700m

Time = 900 s

To find the speed;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Substituting into the equation, we have;

[tex]Speed = \frac{2700}{900}[/tex]

Speed = 3 m/s

A motorbike accellerates from 15m/s to 25m/s in 15 seconds. How far does thew motrobike trsavel in this time?

Answers

Answer:

300 m.

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 15 m/s

Final velocity (v) = 25 m/s

Time (t) = 15 secs

Distance (s) =?

The distance travelled by the motorbike can be obtained as follow:

s = (u + v)t / 2

s = (15 + 25) × 15 / 2

s = 40 × 15 / 2

s = 600 / 2

s = 300 m

Thus, the distance travelled by the motorbike is 300 m.
