The paragraph primarily discusses the concept of overwinding old clocks and its consequences, indicating that overwinding clocks used to be a common mistake. Here option D is the correct answer.

The paragraph explains that overwinding occurs when the mainspring is almost fully wound, but the operator continues to turn the winding key, resulting in the spring coiling too tightly or even breaking.

This suggests that overwinding was a mistake commonly made in the past when operating old-fashioned clocks. The other options, such as clocks changing over the years or clocks becoming fragile with age, are not directly addressed in the paragraph and are therefore less supported.

The option e. "time flies when you're having fun" is unrelated to the paragraph and can be disregarded as an irrelevant answer choice. Hence option D is the correct answer.

Answer:

10 m/s south

Explanation:

From 18 m/s North to 12 m/s South is a total change of 30 m/s towards the South.

So, Change in velocity = 30 m/s South

Time = 3 s

30/3=10 so 10 m/s South

There are six half lives that have passed within 34,200 years. When we assume that we have some of the products present initially, then we overestimate the age of the sample.

The half life is the time taken to obtain only half of the number of atoms that were originally present in the radioactive material. We know that living things do contain the carbon- 14 isotope together with the carbon - 12 isotope in the substance. When the organism dies, the carbon - 14 which is radioactive begins to decay and its half life could be used to estimate the age of the sample as we know.

Given that after each half life, we have only half of the original amount that remains. We would have 1/64 of the original amount left after six half lives and this means that 34,200 years have passed.

If we  the daughter product of carbon-14 is present in the sample when it forms (even before any radioactive decay happens), then we would over estimate the  age of the sample.

Answer: 30.641

Explanation: If you get the ave which is 38.0 then the vi which is 7.359

38.0-7.359=30.641/0.0 which is 30.641

Explanation:

Fgravity = G*(mass1*mass2)/D².

G is the gravitational constant, which has the same value throughout our universe.

D is the distance between the objects.

so, if you triple one of the masses, what does that do to our equation ?

Fgravitynew = G*(3*mass1*mass2)/D²

due to the commutative property of multiplication

Fgravitynew = 3* G*(mass1*mass2)/D² = 3* Fgravity

so, the right answer is 3×12 = 36 units.

Actually Welcome to the concept of resistors,

The equivalent circuit is given as,

1/Rp = 1/3 + 1/6 + 1/9

1/Rp = 6+3+2/18

1/Rp = 11/18

Rp = 18/11 ==> 1.63 ==> 1.6 ohms

hence the equivalent resistance of the circuit is 1.6 ohms

The equivalent resistance of the circuit is 1.6Ω. The correct option is B.

Ohm’s law state that ” At constant temperature, the current (I) flowing through a conductor is directly proportional to the potential difference(V) across the two endpoints of the given conductor.”

I.e V ∝ I

V=IR

Where V= potential difference across the conductor.

I = current flowing through the conductor.

R= constant pf proportionality i.e resistance which unit is ohm(Ω).

There are two ways we can connect the resistors.

(i) series connection

If a number of resistors are said to be connected in series When the same current (I) flows through them.

Let R1, R2, and R3 be the resistors connected in series.

Then the R equivalent is

Req=R1+R2+R3

(ii) parallel connection

A number of resistors are said to be connected in parallel when the same potential difference(V) exists across each of them.

Let R1, R2, and R3 be the resistors connected in parallel.

Then the R equivalent is

1/Req=1/R1+1/R2+1/R3

In this question,

The three resistance connected in parallel by applying the above formula we get,

1/Req=1/R1+1/R2+1/R3

1/Req = 1/3 + 1/6 + 1/9      .................  (∵R1=3Ω,R2=6Ω AND R3=9Ω)

1/Req =11/18

Req=18/11

Req=1.6363Ω

Req≈1.6Ω

Therefore, The equivalent resistance of the circuit is 1.6Ω.

Answer:

The change in momentum experienced by the bowling ball is 96 kgm/s.

Explanation:

Given;

mass of the bowling ball, m = 12 kg

velocity of the bowling ball, v = 8 m/s

time  of motion, t = 10 s

The change in momentum experienced by the bowling ball is equal to the impulse experienced by the bowling ball.

ΔP = J = F x t

\(J = ft =\frac{mv}{t} \times t = mv\\\\J = 12 \times 8\\\\J = 96 \ kg.m/s\)

Therefore, the change in momentum experienced by the bowling ball is 96 kgm/s.

Explanation:

The statue, being initially at rest, will move off at twice the velocity of the center of mass of the Skate-Statue system

The CM velocity is 1.63/2 = 0.815 m/s

so the Skates initial velocity can be found

(117 + 879)(0.815) = 879(0) + 117u

u = 6.93794...

|u| = 6.94 m/s

for elastic collisions, the relative velocity of approach will equal the relative velocity of departure.

Approach velocity 6.94 m/s

Skate's departure velocity 1.63 - 6.94 = - 5.31 m/s

|v| = 5.31 m/s

Recall that average velocity is given by

\(v_{\rm ave}=\dfrac{\Delta x}{\Delta t}\)

Under constant acceleration, we also have

\(v_{\rm ave}=\dfrac{v_i+v_f}2\)

Then

\(\dfrac{\Delta x}{\Delta t}=\dfrac{v_i+v_f}2\)

\(\implies\dfrac{110\,\mathrm m}{\Delta t}=\dfrac{22\frac{\rm m}{\rm s}+3.0\frac{\rm m}{\rm s}}2\)

\(\implies\boxed{\Delta t=8.8\,\mathrm s}\)

The moment of inertia of a rigid body with a cylindrical cross-section is (m*\(r^2\))/2.5, where m is mass and r is radius.

Given data:

Inclination angle, θ = 26 degrees

Distance traveled, s = 10.9 m

Time taken, t = 3.06 s

The acceleration of the body can be found by analyzing its motion down the incline.

Since the body is rolling, we need to consider both translational and rotational motion.

The net force acting on the body is the component of its weight parallel to the incline. Therefore:

Fnet = mgsinθ

The force causes both translational and rotational acceleration. The translational acceleration can be found using Newton's second law:

Fnet = ma

Therefore,

a = Fnet/m = gsinθ

The rotational acceleration can be found using the torque equation:

τ = Iα

where τ is the torque, I is the moment of inertia, and α is the angular acceleration. The torque is provided by the force of friction acting on the body, and it is given by:

τ = Fr

where r is the radius of the body.

The force of friction can be found using the relationship between the translational and rotational acceleration:

a = αr

Therefore

Fr = ma = mgsinθ

Substituting α = a/r and τ = Fr, we get:

I(a/r) = mgsinθ

Substituting a = gsinθ, we get:

I = (m*\(r^2\))/2.5

Therefore, the moment of inertia of the body in terms of its mass m and radius r is I = (m*\(r^2\))/2.5.

remember that the diameter of the broom is much smaller than its length, therefore this moment of inertia is very small

Making height (s), the subject of the formula,

s = E / (m • g)

s = 4000 / (30 • 10)

s = 4000 / 300

s = 13.33 m

Explanation:

The force that will move the box at constant velocity must be a little more than 64 N.

The coefficient of sliding friction is obtained from the formula;

μ= F/R

Where;

F = frictional force

μ = coefficient of sliding friction

R = Normal reaction

It is necessary to note that the force that will move the body must be greater than the frictional force acting between the body and the surface in order to move the body. Hence, the force that will move the box at constant velocity must be a little more than 64 N.
