The angular momentum of a 1kg rock held in place by against the inside wall of the rotating drum can be calculated using the formula L = mvr⊥, where L is the angular momentum, m is the mass, v is the linear velocity and r⊥ is the perpendicular radius from the axis of rotation to the line of motion of the rock. In this case, r⊥ is equal to the radius of the drum, which is 0.2 meters. The linear velocity can be found by multiplying the angular velocity by the radius, i.e. v = ωr. The angular velocity can be obtained by dividing 2π by the period of rotation, i.e. ω = 2π/T. Therefore, the angular momentum of the rock is:

If the period of rotation is 15 seconds, then the angular momentum of the rock is:

A Nichrome wire 42 cm long and 0.28 mm in diameter is connected to a 2.1 V flashlight battery. You don't have to know how the wire is bent because it doesn't affect the resistance of the wire.

Nichrome is a type of resistance wire made from a nickel-chromium alloy. It has a high melting point and can withstand high temperatures. Nichrome wire is commonly used in heating elements, such as those found in toasters and hairdryers. The resistance of a wire depends on its length, cross-sectional area, and resistivity.

The resistance of a wire is given by the formula:

R = (ρl)/AWere,ρ = resistivity

l = length of wire

A = cross-sectional area of the wire

Resistance is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire. Therefore, a longer and thinner wire will have a higher resistance than a shorter and thicker wire. The resistivity of the material is also an important factor that affects the resistance of a wire.Since the length and diameter of the Nichrome wire are given, the resistance of the wire can be calculated using the formula mentioned above. Once the resistance is known, the current flowing through the wire can be calculated using Ohm's law. The voltage of the battery is also given, so the power dissipated by the wire can be calculated. The way the wire is bent does not affect its resistance or other electrical properties, so it is not necessary to know how it is bent.

Therefore, you do not have to know how the Nichrome wire is bent in order to calculate the current through the wire connected to a 2.1V flashlight battery.

According to the law of conservation of momentum, the total momentum of a system remains constant if no external forces act on it the total momentum of the system before and after the collision will be conserved. The correct option d.

The law of conservation of momentum states that in a closed system, the total momentum before a collision is equal to the total momentum after the collision, provided there are no external forces acting on the system. The law applies to both linear and angular momentum.

In the given scenario, the total momentum of the system before the collision is the sum of the momenta of the two disks. After the collision, the total momentum of the system should still be the same as before the collision if no external forces are present.

The individual velocities and directions of the disks after the collision may change, and they may continue to move at different velocities or even come to rest. The law of conservation of momentum does not dictate the velocities or outcomes of the individual objects involved in the collision. It only states that the total momentum of the system remains constant.

Therefore, option d) The total momentum of the system before and after the collision will be conserved is the correct statement according to the law of conservation of momentum.

The current going through the Amperian loop is approximately 0.67 A.

We have to Compute the cross-sectional area of the whole wire to determine the current flowing through the Amperian loop:

Since the radius of the wire is 6 cm, the area A_total is given by the formula

A_total = πr² = π(6 cm)² ≈ 113.1 cm².

The current is distributed uniformly over the wire's cross-sectional area. The total current is 6 A, so the current density J is given by

J = I_total / A_total = 6 A / 113.1 cm² ≈ 0.053 A/cm².

The Amperian loop is concentric to the wire and passes through point P, which is 2 cm from the center. The area A_loop is given by

A_loop = πr² = π(2 cm)² ≈ 12.57 cm².

The current density J is constant across the wire's cross-sectional area, so the current I_loop through the Amperian loop is given by

I_loop = J × A_loop = 0.053 A/cm² × 12.57 cm² ≈ 0.67 A.

The false statement is B) Homolytic bond cleavage yields neutral radicals in which each atom gains one electron.

In homolytic bond cleavage, each atom retains one electron from the shared pair of electrons, resulting in the formation of two neutral radicals, where each atom retains its original number of electrons.

No atoms gain or lose electrons in this process.

In a homolytic bond cleavage, a covalent bond is broken, and the shared pair of electrons is split equally between the two atoms involved in the bond.

This results in the formation of two neutral radicals, with each atom retaining one of the electrons from the shared pair.

A radical is a chemical species characterized by the presence of an electron that is unpaired, meaning it does not have a partner electron with which it forms a complete pair. When a covalent bond is homolytically cleaved, each atom involved in the bond gains one electron, resulting in the formation of two radicals.

These radicals are highly reactive due to the presence of the unpaired electron, which makes them prone to participate in further chemical reactions.

It's important to note that in homolytic bond cleavage, there is no transfer of electrons from one atom to another.

Instead, the bond is broken in a way that allows each atom to retain one of the electrons, leading to the formation of two neutral radicals.

Therefore, statement B, which suggests that each atom gains one electron, is false.

The magnitude of the output gear angular velocity is 50 rad/sec. The actual value of the angular velocity will depend on the specific values of the gear ratio and the input gear's angular velocity.

The magnitude of the output gear angular velocity is determined by the gear ratio between the input and output gears. The gear ratio is the ratio of the number of teeth on the output gear to the number of teeth on the input gear.
To find the magnitude of the output gear angular velocity in units of rad/sec, you can use the formula:
Output gear angular velocity = Input gear angular velocity * (Number of teeth on input gear / Number of teeth on output gear)
Let's say the input gear has 20 teeth and the output gear has 40 teeth. If the input gear is rotating at 100 rad/sec, we

can calculate the output gear angular velocity as follows:
Output gear angular velocity = 100 rad/sec * (20 / 40) = 50 rad/sec
In this case, the magnitude of the output gear angular velocity is 50 rad/sec.

To find the speed of the roller coaster car when it is 10 m up the second hill, we can apply the principle of conservation of energy.

Initially, at the top of the first hill, the roller coaster car possesses gravitational potential energy, given by mgh, where m is the mass of the car (500 kg), g is the acceleration due to gravity (9.8 m/s²), and h is the height of the hill (20 m). At this point, the car also has kinetic energy, given by (1/2)mv², where v is the initial speed (10 m/s).

As the car rolls down the hill and reaches the bottom, all the potential energy is converted into kinetic energy. Thus, we can equate the initial potential energy to the final kinetic energy:

mgh = (1/2)mv²

Simplifying the equation, we find:

gh = (1/2)v²

Now, to find the speed when the car is 10 m up the second hill, we need to calculate the corresponding potential energy at that point. The potential energy is given by mgh, where h is the height of the second hill (10 m).

Setting this equal to the final kinetic energy (1/2)mv², we have:

mgh = (1/2)mv²

Simplifying further:

gh = (1/2)v²

Now we can substitute the values:

(9.8 m/s²)(10 m) = (1/2)v²

Solving for v, we find:

v² = 196 m²/s²

v = √196 m/s

v ≈ 14 m/s

Therefore, the speed of the car when it is 10 m up the second hill is approximately 14 m/s.

None of the provided answer choices (15.3 m/s, 19.7 m/s, 8.9 m/s, 17.2 m/s) match the calculated result of 14 m/s.

To find the image distance formed by a concave mirror, we can use the mirror equation:

1/f = 1/di + 1/do

Where:

f is the focal length of the mirror,

di is the image distance,

and do is the object distance.

In this case, the object distance (do) is given as 12.0 cm, and the focal length (f) is given as 15.0 cm. We can rearrange the equation to solve for the image distance (di):

1/di = 1/f - 1/do

Substituting the given values:

1/di = 1/15 - 1/12

To simplify this expression, we need to find a common denominator:

1/di = (12 - 15)/(12 * 15)

1/di = -3/180

Now, we can invert both sides to find di:

di = 180/-3

di = -60 cm

Therefore, the image distance is -60 cm. The negative sign indicates that the image is formed on the same side as the object (in this case, it is a virtual image).

Answer:

60 cm

Explanation:

the U (obj. distance)  =   12  as it is a concave mirror then u  =  -12cm

the f = -15cm

by mirror formula

1/v  +  1/u =  1/f

by substituting values

1/v  +  (1/-12)  =  1/-15

1/v = 1/-15 -(1/-12)

1/v = 1/-15 + 1/12

by taking L C M  60

1/v = -(4/60)  +  5/60

1/v = 1/60

so V = 60 cm
