What happened when you looked at a light source through both polarizers that were oriented perpendicular to each other
Answers
When looking at a light source through two polarizers oriented perpendicular to each other, the second polarizer blocks or significantly reduces the intensity of the light passing through it due to the phenomenon of polarization.
When two polarizers are oriented perpendicular to each other, the phenomenon of polarization occurs.
In this case, if you look at a light source through both polarizers, you would observe that the intensity of the light passing through the second polarizer significantly decreases or becomes completely blocked.
The reason for this is that polarizers are designed to transmit light waves vibrating in a specific direction while blocking or attenuating light waves vibrating in perpendicular directions.
The first polarizer aligns the incoming light waves with a particular polarization direction.
However, when the light passes through the second polarizer, which is perpendicular to the first one, its polarization direction is no longer aligned with the transmission axis of the second polarizer.
As a result, the second polarizer blocks or significantly attenuates the light passing through it.
This happens because the second polarizer only allows light waves with a polarization direction parallel to its transmission axis to pass through, while light waves with a perpendicular polarization direction are blocked.
In summary, when looking at a light source through two polarizers oriented perpendicular to each other, the second polarizer blocks or significantly reduces the intensity of the light passing through it due to the phenomenon of polarization.

According to the graph, the velocity is approximately..?
Answers
As we know velocity is the rate of change of position with respect to time.
Mathematically \(Velocity = \frac{Position}{Time}\)
Also, in a position-time graph, the velocity of a moving object can be represented by the slope of the graph i.e. Tan\(\alpha\).
\(\alpha\) is the angle made by the slope by the horizontal X-axis.
Distance travelled by the object is recorded on the Y-axis and time taken to complete that particular distance is noted on X-axis.
\(Tan\alpha = \frac{Position}{Time}\)
\(Tan\alpha = Velocity = \frac{x}{t}\)
According to the graph
for x = 8m, t = 2s
\(Tan \alpha = \frac{8}{2}\) = 4 m/s
for x = 12m, t = 3s
\(Tan\alpha = \frac{12}{3}\) = 4 m/s

Where do you think the highest atmospheric pressure will be found?
The atmospheric pressure is strongest at sea level and lowers as you ascend into the atmosphere. At sea level, typical air pressure ranges from 800 to 1050 millibars.
High-pressure regions are often areas of fair, stable weather. Low-pressure zones have a thin atmosphere. Winds sweep inward towards these regions. This causes the air to ascend, resulting in clouds and condensation.
Since warm air rises, areas with warmer air frequently have lower pressure. They are known as low pressure systems. High pressure systems are areas with high air pressure.

Explain why the angle is important when launching projectile motion 
Answers
Answer:
The angle at which a projectile is launched is important because it determines the initial velocity of the projectile and the direction in which it will travel. The angle also affects the projectile's trajectory, or the path that it follows through the air. The steeper the launch angle, the higher the projectile will go and the farther it will travel horizontally. A shallower launch angle will result in a flatter trajectory that does not go as high or travel as far. Therefore, the angle at which a projectile is launched is a key factor in determining how far and how high it will go.
Explanation:
The angle is important when launching projectile motion because it in the calculation of the maximum height, range and time of flight, angle of launching is as important as the magnitude of initial velocity.
What is projectile motion?When a particle is hurled obliquely near the surface of the earth, it travels along a curved path while accelerating continuously in the direction of the planet's center (we assume the particle stays close to the surface of the globe). Such a particle's motion is known as projectile motion, and its route is referred to as a projectile.

Uniform velocity along the x-axis is what causes the particle to move horizontally (ahead).Uniform acceleration along the y-axis is what causes the particle to move vertically (downwards).Learn more about projectile motion here:

Q.7. For a system with a transfer function of G(s)=- co² s² +2a+w² if the natural frequency is 0.5 and the damping ratio is 1.3, which of the following statements is correct regarding the unit step response of the system?
O A) Damped
O B) Undamped
O C) Underdamped
O D) Crittically Damped
O E) Overdamped
Answers
The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)
The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.
To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).
The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).
In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).
Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.
If co > co_critical, the system is considered overdamped (Option E).
If co = co_critical, the system is considered critically damped (Option D).
If co < co_critical, the system is considered underdamped (Option C).
Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.

The line of evidence that is not consistent with the theory of evolution of the horse is: "The fossils of the limbs are different from each other, which indicates these organisms are not related and evolved separately from each other."
The theory of evolution suggests that organisms share a common ancestor and have evolved through gradual changes over time. Therefore, the presence of similar structures and traits among fossilized limbs is consistent with the theory, indicating that these organisms are related and evolved from a common ancestor. If the fossils of the limbs were significantly different from each other, it would suggest that these organisms evolved separately and do not share a common ancestry.

According to magnetic striping, the seafloor is spreading, which provides significant evidence for the hypothesis of plate tectonics. This eruption is frequently referred to as a deep ocean volcano.

The black asteroid caused a greater change in velocity of satellite.
The law of conservation of mass states that :“The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another”.According to the law of conservation of mass, the mass of the reactants must be equal to the mass of the products for a low energy thermodynamic process.Law of conservation of momentum states that : For two or more bodies in an isolated system acting upon each other, their total momentum remains constant unless an external force is applied. Therefore, momentum can neither be created nor destroyed.Momentum is the product of the mass of the object and the velocity at which it is travelling and is also equal to the total force required to bring the object to rest.One of the real-life aspects of the conservation of momentum is collision problems in which the momentum remains conserved and the net external force remains zero.The momentum of an object is the product of the velocity and mass of an object.

What is the unknown mass of the second box shown in the collision below?
Before collision: v= 6 m/s, 7kg
stationary: m
After collision: v= 2 m/s, 7 kg, m
Answers
Answer:
We can use conservation of momentum to solve for the unknown mass of the second box. The total momentum before the collision is equal to the total momentum after the collision.
Before collision:
p = m1v1 = (7 kg)(6 m/s) = 42 kg m/s
After collision:
p = m1v1 + m2v2 = (7 kg)(2 m/s) + m(2 m/s)
Setting the two expressions for momentum equal to each other, we can solve for m2:
42 kg m/s = (7 kg)(2 m/s) + m(2 m/s)
42 kg m/s = 14 kg m/s + 2m kg m/s
28 kg m/s = 2m kg m/s
m = 14 kg
Therefore, the mass of the second box is 14 kg
