Answer

0.16666667m/s (~0.17 m/s) is the speed of putty after colliding with a bowling ball.

Explanation:

The speed of the putty after it collides with the bowling ball can be found using the law of conservation of momentum and the concept of inelastic collisions. The law of conservation of momentum states that the total momentum of a system before a collision is equal to the total momentum of the system after the collision.

Inelastic collisions are collisions where the objects stick together and move as one after the collision. In this case, the initial momentum of the system is given by: momentum before collision = mass of putty × velocity of putty + mass of bowling ball × velocity of bowling ball= 1 kg × 1 m/s + 5 kg × 0 m/s= 1 kg m/s.

The final momentum of the system after the collision is also equal to 1 kg m/s, as there is no external force acting on the system. Since the putty sticks to the bowling ball, they move together as one object after the collision. Let's say their combined speed is v.

The final momentum of the system can be expressed as the mass of the combined object (putty + bowling ball) multiplied by the speed: v × (1 kg + 5 kg) = 1 kg m/s

                                        v = 1/6 m/s.

Therefore, the speed of the putty after it collides with the bowling ball and sticks to it is 1/6 m/s.

When you step out of the shower, the water droplets on your skin quickly evaporate, causing you to feel cold. However, when you dry yourself with a towel, you remove the water droplets, which prevents evaporation and thus, prevents heat loss. This means you feel warmer, even though there is no change in the room's temperature.

When you step out of the shower, you often feel cold. This is because the water droplets on your skin evaporate quickly, which causes heat loss from your body. Since water takes a significant amount of energy to change from a liquid to a gas (evaporation), this energy is taken from your skin to convert the water into water vapor. As a result, your skin loses heat and you feel cold.

However, when you dry yourself with a towel, you remove the water droplets from your skin's surface. This means that there is no more water to evaporate, which prevents heat loss. This means that you feel warmer, even though there is no change in the room's temperature as you stepped out.

Three identical resistors of resistances 5Ω, 10Ω and 30Ω are connected with a battery of 12V\(.\)

We have to find current through the each resistor and equivalent resistance of circuit\(.\)

➝ Equivalent resistance of series connection is given by

➝ We know that, Equal current flow through each resistor in series connection.

➝ As per ohm's law, Current flow through a conductor is directly proportional to the applied potential difference.

◈ Equivalent resistance :

⇒ Req = R1 + R2 + R3

⇒ Req = 5 + 10 + 30

⇒ Req = 45Ω

◈ Current flow in circuit :

⇒ V = IReq

⇒ 12 = I × 45

⇒ I = 0.27A

፨ Therefore, 0.27A current will flow through each resistor.

By determining the value of λ0, we can describe the nonuniform linear charge distribution along the rod more explicitly.

A thin rod of length L and total charge Q has a nonuniform linear charge distribution represented by λ(x) = λ0(x/L), where x is the distance measured from the rod's left end.

In this equation, λ0 is a constant and λ(x) describes the charge density along the rod's length.

Since the charge distribution is nonuniform, the charge density increases as we move from the left end of the rod to the right end. To find the total charge on the rod, we can integrate the charge density function λ(x) with respect to x over the length of the rod:

Q = ∫[λ(x) dx] from 0 to L = λ0 ∫[(x/L) dx] from 0 to L.

Evaluating this integral, we get:

Q = (λ0/L) [x^2/2] evaluated from 0 to L = (λ0/2) L.

This information is useful for analyzing various physical properties, such as the electric field produced by the rod or the potential energy stored in the system.

The total momentum of the system consisting of a 4.00 kg ball moving at 4.00 m/s to the east and a 6.00 kg ball moving at 3.00 m/s to the north is calculated as follows:

Firstly, it is important to note that momentum is a vector quantity which means that it has both magnitude and direction. The magnitude of the momentum is given by the product of mass and velocity while the direction is the same as that of the velocity vector of the object.

Considering the east direction to be the positive x-direction and the north direction to be the positive y-direction, we can resolve the velocities of the two balls into their x and y-components:

Velocity of the 4.00 kg ball in the x-direction = 4.00 m/s Velocity of the 6.00 kg ball in the y-direction = 3.00 m/s

Next, we can use the definition of momentum to find the momentum of each ball:

Momentum of the 4.00 kg ball = mass x velocity= 4.00 kg x 4.00 m/s = 16.00 kg m/s (in the positive x-direction) Momentum of the 6.00 kg ball = mass x velocity= 6.00 kg x 3.00 m/s = 18.00 kg m/s (in the positive y-direction)

The momentum of the system is the vector sum of the momenta of the two balls. Since the momenta are at right angles to each other, we can use the Pythagorean theorem to find the magnitude of the resultant momentum:

Total momentum of the system = √(16.00² + 18.00²) kg m/s≈ 23.55 kg m/sThe direction of the resultant momentum can be found by taking the inverse tangent of the ratio of the y-component to the x-component: tan⁻¹(18.00/16.00)≈ 50.2° north of east

Therefore, the total momentum of the system is approximately 23.55 kg m/s north of east.

All of the below contribute to an increase in carbon levels except D. Photosynthesis.

Carbon is an essential component of life on earth, and its role is crucial in maintaining the balance in the atmosphere. However, increased carbon levels, mainly carbon dioxide (CO₂), pose a threat to our planet and all the living beings on it. Burning fossil fuels, deforestation, and industrial processes are the major contributors to the increased levels of CO₂ in the atmosphere. Hence, humans play a significant role in climate change. However, the process of photosynthesis can reduce the carbon levels in the atmosphere as it involves absorbing CO₂ from the air and converting it into oxygen (O₂) and glucose.

Breathing is the process where humans and animals take in oxygen and release CO₂ into the atmosphere. Although breathing increases the levels of CO₂ in the atmosphere, it is not considered a significant contributor to the increased carbon levels. Decay of vegetation contributes to the increase in carbon levels as it releases CO₂ into the atmosphere during the process. Petrol burning releases CO₂ into the atmosphere and contributes significantly to climate change. Therefore, the correct answer to this question is option D, photosynthesis

The radius of the satellite's motion is 2.49 × 10⁷ m

Since the centripetal force, F = mv²/r equals the gravitational force, F' = GMm/r² on the satellite,

F = F'

mv²/r = GMm/r²

v² = GM/r

Making r subject of the formula, we have

r = GM/v² where r = radius of satellite's motion, G = universal gravitational constant = 6.67 × 10⁻¹¹ Nm²/kg², M = mass of earth = 5.972 × 10²⁴ kg and v = speed of satellite = 4,000 m/s.

Substituting the values of the variables into the equation, we have

r = GM/v²

r = 6.67 × 10⁻¹¹ Nm²/kg² × 5.972 × 10²⁴ kg/(4,000 m/s)²

r = 39.83324 × 10¹³ Nm²/kg ÷ 16 × 10⁶ m²/s²

Explanation:

This is the correct answer.

The net force on the car during its deceleration is -8092.71 N (in the negative direction).

To solve this problem, we need to use the equations of motion and Newton's second law of motion.

First, let's find the acceleration of the car during the acceleration phase:

Initial velocity, u = 0 m/s

Final velocity, v = 84.0 km/h = 23.3 m/s

Time, t = 10.0 s

Using the equation v = u + at, we get:

\(a = (v - u) / t\)

\(a = (23.3 \ m/s - 0\  m/s) / 10.0\  s\)

\(a = 2.33 \ m/s^2\)

Therefore, the acceleration of the car during the acceleration phase is \(2.33 \ m/s^2\).

Next, let's find the deceleration of the car during the braking phase:

Initial velocity, \(u = 23.3 \ m/s\)

Final velocity, v = 0 m/s

Distance, s = 38.0 m

Using the equation \(v^2 = u^2 + 2as\), we get:

\(a = (v^2 - u^2) / 2s\)

\(a = (0\  m/s - (23.3 \ m/s)^2) / (2 \times 38.0\  m)\)

\(a = -7.16 \ m/s^2\)

Therefore, the deceleration of the car during the braking phase is 7.16 m/s^2. The negative sign indicates that the acceleration is in the opposite direction of the car's motion.

Now, using Newton's second law of motion, we can find the net force on the car during the deceleration phase:

Force = mass x acceleration

\(Force = 1,130.0\  kg \times (-7.16 \ m/s^2)\)

\(Force = -8,092.71 \ N\)

Therefore, the net force on the car during the deceleration phase is\(-8092.71\  N\), where the negative sign indicates that the force is in the opposite direction to the car's motion.
