It is possible to suspend an object at rest from its center of gravity, and gravity won't induce it to begin rotating no matter how it is positioned.  

Thus, The center of gravity of an object will be located somewhere along a vertical line that passes through the point of suspension if you suspend it from any point and allow it to come to rest.

The gravitational acceleration is (almost) constant near the surface of the earth, where the center of mass also lies.

A place that represents the average or typical location of an object's mass, as if all of the mass were contained there, is known as the center of mass (CM). The geometric center of a uniform sphere serves as its center of mass. The barycenter is another name for the CM.

The gravitational force acting between the objects is 6.67 x 10⁻⁹N.

If the mass of one of the objects is doubled, the gravitational force also doubles.

The new gravitational force is 32 N.

1) Mass of the objects, m = 100 kg

Distance between the masses, r = 10 m

Gravitational force acting between the objects,

F = Gm²/r²

F = 6.67 x 10⁻¹¹ x 100²/10²

F = 6.67 x 10⁻⁹N

2) If mass of one of the objects is doubled, the gravitational force between the objects,

F = Gm x 2m/r²

F = 6.67 x 10⁻¹¹ x 100 x 200/10²

F = 13.34 x 10⁻⁹N

So, if the mass of one of the objects is doubled, the gravitational force also doubles.

3) According to the equation for the gravitational force between the objects, it is clear that the gravitational force is directly proportional to the product of their masses.

F ∝ m₁m₂

4) The gravitational force becomes double of the original force.

So, F' = 2 x 16

Yes, your friend is correct. Dividing both the divisor and dividend by the same value will result in an equivalent problem with a whole number division.

In this case, dividing both 4.44 (dividend) and 0.64 (divisor) by 0.01 will give us:

4.44 ÷ 0.64 = (4.44 ÷ 0.01) ÷ (0.64 ÷ 0.01) = 444 ÷ 64

By dividing both the dividend and divisor by 0.01, we essentially multiply them by 100, since dividing by 0.01 is the same as multiplying by 100.

Now we have a division problem with whole numbers: 444 ÷ 64. This can be solved using traditional long division to find the quotient, which in this case would be a whole number.

So, your friend is correct in saying that dividing both the divisor and dividend by 0.01 will result in an equivalent problem with a whole number division.

In cartesian coordinates, we can write the position vectors as-

a) → r = 12.4 m , θ = 170°    ↔     - 12.21 i + 2.15 j

b) → r = 4 cm , θ = 50°   ↔    2.57 i + 3.06 j

c) → r = 20 inches , θ = 210°   ↔    - 17.32 i - 10 j

It is two-dimensional coordinate system which uses a straight line distance (from a reference point) and the angle made by it (with respect to reference direction) to represent a point in the X-Y plane.

Given are the position vectors in polar coordinates of three points in X-Y coordinate system.

The transformation from polar coordinates (r, θ) into cartesian coordinates (x, y) is done using the following formulae -

x = r cosθ

y = r sinθ

a) → r = 12.4 m , θ = 170°

x = 12.4 x cos (170°) = 12.4 x -0.98480775301 = -12 .21

y = 12.4 x sin (170°) = 12.4 x 0.17364817766 = 2.15

In cartesian form → ( -12.21 i + 2.15 j )

b) → r = 4 cm , θ = 50°

x = 4 x cos (50°) = 4 x 0.64278760968 = 2.57

y = 4 x sin (170°) = 4 x 0.76604444311 = 3.06

In cartesian form → ( 2.57 i + 3.06 j )

c) → r = 20 inches , θ = 210°

x = 20 x cos (210°) = 20 x -0.86602540378 = -17.32

y = 20 x sin (210°) = 20 x -0.5= -10

In cartesian form → ( -17.32 i - 10 j )

Therefore, in cartesian coordinates, we can write the position vectors as -

a) → r = 12.4 m , θ = 170°    ↔     - 12.21 i + 2.15 j

b) → r = 4 cm , θ = 50°   ↔    2.57 i + 3.06 j

the elevator `d` meters above the ground. In order to calculate the time of flight of the bolt from ceiling to floor, andthe distance the bolt has fallen relative to the elevator shaft Let's figure out how long it takes for the bolt to fall from the ceiling to the floor.

To do so, we'll need to figure out how far the bolt falls. In other words, we need to figure out how high above the floor the bolt was when it fell. bolt is `d` meters above the ground when it falls. The elevator is rising at an acceleration of `a` meters per second per second. The time it takes for the bolt to hit the ground is given by `t`. Using the formula for distance covered in time `t` for an accelerating object: `d = 0.5at^2 + vt + d`, we can solve for `t`. The initial velocity is `v = 0` since the bolt is dropped, so the equation becomes: `d = 0.5at^2 + d`. Rearranging, we get: `t = sqrt(2d/a)`.Therefore, the time of flight of the bolt from ceiling to floor is `t = sqrt(2d/a)`.Now we need to find out how far the bolt has fallen relative to the elevator shaft. Since the bolt is falling, it is accelerating at a rate of `g = 9.8` meters per second per second, downwards.

The elevator is rising at an acceleration of `a` meters per second per second, upwards.Let `y` be the distance that the elevator has risen in time `t`. Using the formula for distance covered in time `t` for an accelerating object, we can write the equation `y = vt + 0.5at^2`. The initial velocity is `v`, and the acceleration is `a`, so `y = vt + 0.5at^2`.The distance that the bolt has fallen relative to the elevator shaft is equal to the distance it would have fallen if the elevator had not been moving. In other words, if the elevator were stationary, the bolt would have fallen straight down, a distance of `0.5gt^2`.Therefore, the distance the bolt has fallen relative to the elevator shaft is: `0.5gt^2 - y`.Simplify `0.5gt^2 - y` by substituting the value of `y` in terms of `t`. Therefore, `0.5gt^2 - y = 0.5gt^2 - (vt + 0.5at^2) = 0.5g t^2 - vt - 0.5at^2`.So, the distance that the bolt has fallen relative to the elevator shaft is `0.5g t^2 - vt - 0.5at^2`.Explanation:From the above answer, we can conclude that:Time of flight of the bolt from ceiling to floor is `t = sqrt(2d/a)`Distance the bolt has fallen relative to the elevator shaft is `0.5g t^2 - vt - 0.5at^2`.

The current in each resistor is 4 A, 2 A, and 4 A, respectively. The voltage drop across each resistor is 12 V.

When three resistors are connected in series with a six resistor and a 12-volt battery, the total resistance of the series circuit is R = R1 + R2 + R3 + ...

The current flowing through the circuit is the same at every point. So, if we want to know the current flowing through each resistor, we need to use Ohm's law, I = V/R, where V is the voltage of the battery and R is the resistance of each resistor.

I1 = V/R1 = 12/3 = 4 AI2 = V/R2 = 12/6 = 2 AI3 = V/R3 = 12/3 = 4 A. The voltage drop across each resistor can be calculated using Ohm's law, V = IR.

The amplitude of the current (I), however, will decrease, as the higher frequency results in a larger inductive reactance, leading to a decrease in current.

In a circuit with a purely capacitive load, if the driving frequency is increased, the amplitude of the voltage across the capacitor (Vc) will decrease.

This is because as the frequency increases, the capacitor has less time to charge and discharge, leading to a decrease in the voltage across it. The amplitude of the current (I) will increase, however, as the higher frequency results in a smaller capacitive reactance, leading to an increase in current.

In a circuit with a purely inductive load, if the driving frequency is increased, the amplitude of the voltage across the inductor (V) will increase.

Answer:

The acceleration of the car is \(-7\ m/s^2\)

The distance traveled before stopping is 350 m

Explanation:

Constant Acceleration Motion

It's a type of motion in which the velocity of an object changes by an equal amount in every equal period of time.

Being a the constant acceleration, vo the initial speed, vf the final speed, and t the time, the following relation applies:

\(v_f=v_o+at\qquad [1]\)

The distance traveled by the object is given by:

\(\displaystyle x=v_o.t+\frac{a.t^2}{2}\qquad [2]\)

The car has an initial speed of v0=70 m/s when the driver sees a cow in the road and steps on the brakes with an (assumed) constant acceleration during t=10 seconds before stopping (vf=0).

With the information provided, we can calculate the value of the acceleration and the distance traveled.

Using the equation [1] we can solve for a:

\(\displaystyle a=\frac{v_f-v_o}{t}\)

Substituting the numerical values:

\(\displaystyle a=\frac{0-70}{10}=-7\ m/s^2\)

The acceleration of the car is \(-7\ m/s^2\)

The distance is now calculated by using [2]

\(\displaystyle x=70\cdot 10+\frac{(-7)\cdot 10^2}{2}\)

\(\displaystyle x=700-\frac{700}{2}=350\ m\)

The distance traveled before stopping is 350 m

Using the thin lens formula, the image height is calculated to be approximately 2.4 mm.

To calculate the image height, we need to use the thin lens formula:

1/f = 1/do + 1/di

Where f is the focal length, do is the object distance, and di is the image distance.

In this case, the object is the person standing 27 m away, so do = 27,000 mm. The focal length is given as 75 mm. The image distance is the distance from the lens to the film, which is typically the same as the focal length. Solving for di, we get di = 74.999 mm.

Now we can use similar triangles to find the image height:

(image height) / (object height) = (image distance) / (object distance)

Plugging in the numbers, we get (image height) / 1800 = 74.999 / 27,000. Solving for the image height, we get approximately 2.4 mm.
