a pendulum clock runs fast, how should the length of the pendulum be adjusted to correct the problem?
Answers
If a pendulum clock is running fast, the length of the pendulum should be increased to correct the problem.
The time period of a simple pendulum clock is:
T= 2π√(l/g)
Where,
l is the length of the simple pendulum and g is the gravity.
From the formula, we can see that the time period is directly proportional to the square root of the length. Decreasing the length will decrease the time period and the clock will move faster.
In order to slow the clock, increase the length of the pendulum to increase the time period.

.If you looked at a light through the lenses from two polarizing sunglasses that were overlapped at right angles to each other: a) all of the light would pass through b) most of the light would pass through c) little of the light would pass through d) none of the light would pass through
Answers
When two polarizing lenses are overlapped at right angles, the polarization axes are perpendicular to each other. In this configuration, option d) "none of the light would pass through" is correct.
When two polarizing sunglasses are overlapped at right angles to each other, the amount of light that passes through depends on the orientation of the polarization axes in each lens.
Polarizing sunglasses are designed to block light waves vibrating in certain orientations while allowing light waves vibrating in other orientations to pass through. The lenses have a built-in filter that transmits light waves with a specific polarization axis while absorbing or blocking light waves with perpendicular polarization axes.
Since the polarization axes of the two lenses are orthogonal, the first lens will block all the light waves that are not aligned with its polarization axis. The second lens, with its polarization axis at a right angle to the first lens, will also block all the remaining light waves that managed to pass through the first lens. As a result, no light would be able to pass through both lenses, and no light would be visible when looking at a light source through them.

An arrow is shot horizontally from a height of 4.9 m above the ground. The initial speed of the arrow is 45 m/s. Neglecting friction, how far away from the archer will the arrow to hit the ground?
Answers
Answer:
90m
Explanation:
Given that an arrow is shot horizontally from a height of 4.9 m above the ground. The initial speed of the arrow is 45 m/s.
Since the arrow is shot horizontally, the initial vertical velocity will be equal to zero.
Using the second equation of motion,
h = Ut + 1/2gt^2
substitute h = 4.9m and g into the formula
4.9 = 1/2 × 9.8 × t^2
4.9 = 4.9t^2
t^2 = 4.9/ 4.9
t = 1
For horizontal motion g = 0 and the total time T = 2t
T = 2 × 1
T = 2
Substitute T and U into the equation
R = UT
R = 45 × 2
R = 90m
Therefore, the arrow will hit the ground 90m away from the archer.
Answer: 45 meters.
Explanation:
First, let's calculate the time that the arrow needs to hit the ground.
Let's analyze the vertical axis.
The only force acting on the arrow is the gravitational force, then the only acceleration will be the gravitational acceleration.
We can write this as:
a(t) = -g
where = 9.8m/s^2
For the vertical velocity, we can integrate the above equation over the time:
v(t) = -g*t + v0
where t is our variable, the time in seconds, and v0 is the initial vertical velocity.
But we know that the arrow is shot horizontally, then we don't have initial vertical velocity: v0 = 0m/s.
v(t) = -g*t
and the vertical position can be obtained integrating again.
p(t) = -0.5*g*t^2 + p0
Where p0 is the initial position, we know that this is 4.9 meters, then the position equation is:
p(t) = -0.5*9.8m/s^2*t^2 + 4.9m
Now we want to find the value of t where the position is equal to zero, this will be the time that the arrow needs to hit the ground.
0 = -0.5*9.8m/s^2*t^2 + 4.9m
t^2 = 4.9/(0.5*9.8) s^2
t = √( 4.9/(0.5*9.8) s^2 ) = 1s
Now let's analyze the horizontal case.
As we can neglect the air resistance, the horizontal velocity is constant:
v(t) = 45m/s
And the position will be:
V(t) = 45m/s*t + p0
Where in this case p0 is the position of the archer, that we can define as our zero in this axis, then p0 = 0m
Now we know that the vertical displacement of the arrow when it hits the ground will be:
p(1s) = 45m/s*1s = 45m

Answers
Given data:
* The mass on the frictionless table is,
\(m_1=6\text{ kg}\)* The mass hangs freely from the string is,
\(m_2=6.8\text{ kg}\)* The hanging mass falls a distance is,
\(d=0.9\text{ m}\)Solution:
(1). The normal force of mass on the frictionless table is,
\(\begin{gathered} F_N=m_1g \\ F_N=6\times9.8 \\ F_N=58.8\text{ N} \end{gathered}\)As the displacement of the mass m_1 on the frictionless table is in the hroizontal direction.
Thus, the work done by teh normal force is,
\(W=F_Nd\cos (\theta)\)\(\text{where }\theta\text{ is the angle between the normal force and dispalcement}\)As both the normal force and displacement are perpendicuular to each other.
Thus, the work done by the nromal force on the mass m_1 is,
\(\begin{gathered} W=F_Nd\cos (90^{\circ}) \\ W=0 \end{gathered}\)Thus, the work done by the normal force on m_1 is zero.

When the diameter of one telescope is twice that of another, how does its collecting area compare?
the larger telescope will produce brighter images compared to the other, smaller one
Answers
When the diameter of one telescope is twice that of another, the larger telescope will have four times the collecting area of the smaller one.
The collecting area of a telescope is proportional to the square of its diameter. A telescope's diameter is important because it determines the amount of light that enters the instrument. The amount of light that a telescope can gather is proportional to the square of its diameter. This means that if one telescope has a diameter twice that of another, it can gather four times as much light.
In other words, the collecting area of a telescope is proportional to the square of its diameter. This means that if one telescope has a diameter twice that of another, its collecting area is four times greater than that of the smaller telescope. Therefore, the larger telescope will produce brighter images than the smaller one.

what would happen to a floating object on top of the pond water?
Answers
A floating object on top of pond water would stay afloat due to buoyancy.
When an object is placed on top of a liquid, such as pond water, it experiences an upward force called buoyancy. This force is exerted by the liquid and is equal to the weight of the liquid displaced by the object. As long as the buoyant force is greater than or equal to the weight of the object, the object will float. This occurs because the density of the object is lower than the density of the liquid, allowing it to displace a volume of liquid greater than its own weight. As a result, the floating object will remain on the surface of the pond water.

A man pulls 10m of rope to raise a package 2m. The man applies a force of 250 n to lift a 1000 n package
Answers
To calculate the work done by the man to lift the package, we need to use the formula:
Work = force x distance x cos(theta), where force is the force applied by the man (250 N), distance is the distance the rope is pulled (10 m), and cos(theta) is the angle between the direction of the force and the direction of the displacement (in this case, it is 0 because the force is applied in the same direction as the displacement). The work done by the man to lift the package is then: Work = 250 N x 10 m x cos(0) = 2500 J. To lift the 1000 N package a distance of 2 m, the work done by the man must be equal to the work done against gravity, which is given by: Work = force x distance = 1000 N x 2 m = 2000 J. Therefore, the man's force of 250 N was sufficient to lift the 1000 N package a distance of 2 m, and he did 2500 J of work in the process.

Three balls are thrown from a cliff with the same speed but at different angles. Which ball has the greatest speed just before it hits the ground
Answers
Answer:All three balls have the same initial speed, so they all have the same horizontal component of velocity. However, the vertical component of velocity and the angle of projection affect how long it takes for each ball to hit the ground and at what speed.
Assuming all three balls are thrown from the same height, the ball that is thrown at the smallest angle above the horizontal will hit the ground with the greatest speed. This is because the vertical component of velocity is the greatest for this ball, and it has the longest distance to fall.
To see this, consider the equations for the vertical and horizontal components of velocity:
v_y = v_i * sin(theta)
v_x = v_i * cos(theta)
where v_y and v_x are the vertical and horizontal components of velocity, respectively, v_i is the initial speed, and theta is the angle of projection.
The time it takes for the ball to hit the ground can be found using the equation:
t = 2 * v_i * sin(theta) / g
where g is the acceleration due to gravity.
The vertical velocity of the ball just before it hits the ground is:
v_y_final = v_y_initial - g * t
Substituting the expressions for v_y and t and simplifying, we get:
v_y_final = v_i * sin(theta) - 2 * v_i * sin(theta) = -v_i * sin(theta)
The negative sign indicates that the ball is moving downward.
Since the initial speeds are the same for all three balls, the ball with the smallest angle above the horizontal will have the greatest sin(theta) and hence the greatest final vertical velocity. Therefore, it will hit the ground with the greatest speed.
Explanation:
When three balls are thrown from a cliff with the same speed but at different angles, they will all hit the ground with the same final speed since they are all affected by the same gravitational acceleration.
However, the angles at which the balls are thrown will determine their velocities in the horizontal and vertical directions, which will affect their paths and trajectories.
The ball that is thrown at a shallower angle, closer to the horizontal, will have a greater horizontal velocity component, allowing it to travel further along the ground before hitting the ground.
The ball that is thrown at a steeper angle, closer to the vertical, will have a greater vertical velocity component, allowing it to reach a higher maximum height before eventually hitting the ground.
Thus, while all three balls will hit the ground with the same final speed, the ball that was thrown at the shallower angle will have the greatest speed just before it hits the ground, due to its higher horizontal velocity component.
