An object rotating counterclockwise can have a positive angular acceleration if its angular velocity is also increasing in a counterclockwise direction. This means that the rate at which the object is rotating is increasing in the same direction in which it is already rotating, resulting in a positive angular acceleration.

The direction of the angular acceleration depends on the direction of the torque that is acting on the object. When a torque is applied to an object rotating counterclockwise, it can either increase the rate of rotation or decrease it. If the torque is applied in the same direction as the object's rotation, it will increase the rate of rotation, resulting in a positive angular acceleration.

If the object is rotating counterclockwise and its angular velocity is also increasing in the counterclockwise direction, then it has a positive angular acceleration. This can happen when an external torque is applied to the object in the counterclockwise direction, causing it to rotate faster. For example, a wheel being pushed counterclockwise by a motor will have a positive angular acceleration as its speed increases in the counterclockwise direction.

In conclusion, an object rotating counterclockwise can have a positive angular acceleration if its angular velocity is also increasing in a counterclockwise direction, which can happen when an external torque is applied in the same direction as the object's rotation.

When a stone is propelled vertically off the ground its kinetic energy decreases and gravitational potential energy increases.

When an object is propelled upwards at first it have the highest kinetic energy. The total energy will be equal to kinetic energy and potential energy will be 0. When it reaches midway through the air, the kinetic energy gradually decreases and potential energy increases, because some of the kinetic energy is converted to gravitational potential energy.

When the object reaches the maximum height, the Kinetic energy will become 0, and object stops moving forward. Here all the kinetic energy i converted to gravitational potential energy. Potential energy will be maximum at this point. After this the object begins to fall attaining some kinetic energy.

So when an object is thrown vertically upwards, the kinetic energy decreases and gravitational energy increases. The total energy will remain constant throughout.

The flaw in the experiment on water recycling is that the student did not see water dripping off the glass plate as expected. To correct this flaw, the student should use a cold glass plate instead of a hot glass plate.

The correct option to the given question is option 4.

When the student holds the hot glass plate above the beaker, the water vapor in the atmosphere will come into contact with the cold surface of the plate and condense, forming water droplets. However, if the glass plate is already hot, it will not be able to cool down the water vapor quickly enough for condensation to occur.

By using a cold glass plate, the temperature difference between the plate and the water vapor will be greater, allowing for faster condensation. This will result in water droplets forming on the glass plate and dripping off, demonstrating the process of water recycling through the atmosphere.

Therefore, the correct method to correct the flaw in this experiment is to use a cold glass plate instead of a hot glass plate. This will enable the student to observe water droplets on the glass plate as expected.

An unmarked police car traveling at a constant speed of 95 km/h is passed by a speeder traveling at 139 km/h. Precisely 1.00 s after the speeder passes, the police officer steps on the accelerator. If the police car's acceleration is 2.40 m/s².The time it takes for the police car to overtake the speeder is approximately 1.35 seconds.

To solve this problem, we can first determine the distance traveled by both the speeder and the police car during the 1.00 s interval. Then we can calculate the time it takes for the police car to overtake the speeder.

Let's convert the speeds of the speeder and the police car from km/h to m/s:

Speed of the speeder (Vs) = 139 km/h = 38.61 m/s

Speed of the police car (Vp) = 95 km/h = 26.39 m/s

During the 1.00 s interval, the distance traveled by the speeder can be calculated as follows:

Distance traveled by the speeder = Vs × t

= 38.61 m/s × 1.00 s

= 38.61 m

Now, let's calculate the distance the police car needs to catch up with the speeder. The police car is initially behind by the distance traveled by the speeder during the 1.00 s interval.

Distance needed to catch up = 38.61 m

To determine the time it takes for the police car to overtake the speeder, we can use the equation of motion:

Distance = Initial velocity × Time + 0.5 × Acceleration × Time^2

For the speeder, the initial velocity is vs and the acceleration is 0 m/s² because the speeder is assumed to be moving at a constant speed. Therefore, the equation becomes:

Distance = Vs × t

For the police car, the initial velocity is Vp and the acceleration is 2.40 m/s². The equation becomes:

Distance = Vp × t + 0.5 * 2.40 m/s² * t^2

Since the distance traveled by the police car is equal to the distance needed to catch up, we can set the two equations equal to each other:

Vp  t + 0.5 ×2.40 m/s² × t^2 = 38.61 m

Simplifying the equation:

26.39 m/s × t + 1.20 m/s² × t^2 = 38.61 m

Rearranging the equation:

1.20 m/s² × t^2 + 26.39 m/s × t - 38.61 m = 0

Now, we can solve this quadratic equation using the quadratic formula:

t = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 1.20 m/s², b = 26.39 m/s, and c = -38.61 m.

Calculating the values:

t = (-26.39 ± sqrt(26.39^2 - 4  1.20 * -38.61)) / (2 * 1.20)

After evaluating the expression, we get two possible values for t: t1 ≈ 1.35 s and t2 ≈ -23.24 s. Since time cannot be negative in this context, we discard the negative value.

Therefore, the time it takes for the police car to overtake the speeder is approximately 1.35 seconds.

The total time from when the police car is passed by the speeder until the police car catches up to the speeder is approximately 15.80 seconds, considering the constant speed of the speeder and the acceleration of the police car.

In this scenario, we first need to convert the speed from km/h to m/s as the acceleration is given in m/s². Hence, the speeder's speed is 139 km/h = 38.61 m/s and the police car's initial speed is 95 km/h =  26.39 m/s. The officer starts accelerating 1.00 s after being passed, hence the police car travels at 26.39 m/s for 1.00 s, covering 26.39 m of distance. In the next phase when the police car accelerates, we can use the relative speed and distance. The speeder and the police car will meet each other when they cover the same relative distance. So, we can use the formula d = vt + 0.5at², where 'd' is the total distance covered by both, 'v' is the relative initial velocity, 'a' is the acceleration, and 't' is time after the police car starts accelerating. Solving, you get t ≈ 14.80 s. Hence, the total time passes after the police car is passed by the speeder and before the police car overtakes the speeder is 1.00 s + 14.80 s = 15.80 s.

Therefore, the sphere that rolls down the ramp without slipping will reach the bottom of its ramp first due to its combined translational and rotational motion, which allows it to cover more distance in less time than the block sliding down the frictionless ramp.

The sphere that rolls down the ramp without slipping will reach the bottom of its ramp first. This is because when the sphere rolls down the ramp, its rotational kinetic energy is converted into translational kinetic energy, meaning that it is moving both rotationally and translationally. This allows it to cover more distance in less time than the block sliding down the frictionless ramp, which only has translational kinetic energy.

In contrast, the block sliding down the frictionless ramp will only have translational kinetic energy, and will not be able to cover as much distance as the rolling sphere in the same amount of time. Additionally, the rolling sphere has a lower acceleration due to the presence of rolling friction, which allows it to maintain a more constant velocity as it moves down the ramp. The sliding block, on the other hand, has a higher acceleration and may reach the bottom of the ramp faster initially, but will quickly lose its kinetic energy and come to a stop due to friction with the ground.

Explanation:

A 49 kg girl rides on a 4.2 kg skateboard. The girl on the skateboard moves at 1.0 m/s. If the girl jumps off the skateboard backwards with a velocity of 1.6 m/s, the skateboard rolls away at 31.3 m/s.

Law of conservation of linear momentum states that the total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and speed v is  

P=mv.  

If we have a system of bodies, then the total momentum is the sum of the individual momentums:

P = m₁v₁ +m₂v₂

If a collision occurs and the velocities change to v', the final momentum is:

P' = m₁v₁' +m₂v₂'

Since the total momentum is conserved, then:

P = P'

m₁v₁ +m₂v₂ =m₁v₁'  +m₂v₂'

A girl of m1 = 49 kg rides an m2 = 4.2 kg skateboard and the common speed is v1 = v2= 1 m/s.

The girl jumps off the skateboard backward with a speed of v1'=-1.6 m/s (negative because it's opposite to the original direction). It's required to find the final speed of the skateboard. It will be calculated by solving for v2':

v₂'= m₁v₁ +m₂v₂ - m₁v₁' / m₂

    = (49 × 1) + ( 4.2 × 1 ) - ( 49× (- 1.6) / 4.2
