Answer:

Forces Acting in Opposite Directions

In general, whenever forces act on an object in opposite directions—like the book on the table—the net force is equal to the difference between the two forces. In other words, one force is subtracted from the other to calculate the net force.

Hope I helped!!!

The worker will accelerate to the right with an acceleration of 0.22 m/s². (a): the worker will accelerate at 1.08 m/s² and the box will accelerate at 0.89 m/s², but in opposite directions.

By doing a running high jump, an athlete can only create a maximum vertical velocity of around 3–4 m/s, but a quick run-up can provide a horizontal take-off velocity of roughly 8–10 m/s.

F_net = ma

F_net_box = F_worker - F_gravity_box

F_net_box = 200 N - 1800 N

F_net_box = -1600 N

F_net_box = ma_box

-1600 N = 1800 kg * a_box

a_box = -0.89 m/s² (to the left)

For the worker, the net force acting on them is equal to the force they are applying to the box:

F_net_worker = F_push = 200 N

We can find the acceleration of the worker using Newton's second law:

F_net_worker = ma_worker

200 N = 900 kg * a_worker

a_worker = 0.22 m/s² (to the right)

Therefore, the worker will accelerate to the right with an acceleration of 0.22 m/s².

Explanation:

The impulse response of a digital filter represents how the filter will react to an impulse input. In this case, the impulse response is {1, -2, 1}, which means that if an impulse signal is applied to the filter, the output will be {1, -2, 1}.

To find the response of the filter to a unit step input, we can convolve the unit step signal with the impulse response. The unit step signal is a signal that has a value of 0 for all negative time values and a value of 1 for all positive time values.

To perform the convolution, we will multiply the impulse response by the unit step at different time instants and sum the results.

At time t = 0, the unit step signal is 1, so the response of the filter is 1 * 1 = 1.

At time t = 1, the unit step signal is also 1, so the response of the filter is 1 * (-2) = -2.

At time t = 2, the unit step signal is still 1, so the response of the filter is 1 * 1 = 1.

Therefore, the response of the filter to the unit step is {1, -2, 1}, which is the same as the impulse response.

In conclusion, when a unit step signal is applied to a filter with an impulse response of {1, -2, 1}, the filter will produce an output of {1, -2, 1}.

Answer:

They are linearly proportional, i.e. the higher the ball is, the more potential energy it has.

Explanation:

The formula for gravitational potential energy is PE=mgh where m is mass of the object, h is height above the ground and g is the constant of gravitational acceleration (9.81 m=s²). So, if we increase the heigth, the potential energy also increases.

1) Which block has the greatest density?

Answer: Block A

2) Which block has the lowest density?

Answer: Block B

Explanation: For the first question, Block A has the largest whole number, making it have the greatest density.

For the second question, Block B 0.64 has the lowest number behind the decimal in the tenths place is the smallest, making it have the lowest density.

Hope this helps :3

1)We need to identify the block that has the highest mass per unit volume. In this case, it is Block A, which has a density of 19.3 Kg/L. So Block A has greater density. Correct Option is 1.

2) Block B: 0.64 Kg/L block has the lowest density. So Correct Option is 2.

1)  Block A with a density of 19.3 Kg/L, it means that for every liter of volume occupied by the block, there is 19.3 kilograms of mass. This indicates that the material in Block A is more dense or more tightly packed compared to the other blocks with lower densities.

2) Block B has the lowest density among the given blocks because it has the smallest value of 0.64 Kg/L. Density is a measure of how much mass is contained within a given volume. A lower density means that there is less mass packed into a given volume, indicating that the material is less dense or less compact

The density of the object is 5911.94 kg/m³

An object's buoyancy is the upward force produced by a fluid in opposition to the weight of a partly or totally submerged object.

The buoyancy = weight of the object - weight in water

= 15 N - 13N

= 2 N

The buoyancy force can also be determined by using the expressed:

\(\mathbf{F_B = Volume (V) \times density ( \rho) \times g}\)

\(\mathbf{2 = Volume (V) \times788 \ kg/m^3 \times9.8 }\)

\(\mathbf{ Volume (V) = \dfrac{2}{ 788 \ kg/m^3 \times9.8 }}\)

volume (v) = 2.589 × 10⁻⁴m³

Recall that:

The mass of an object can be estimated by using the formula:

Weight = mass × gravity

mass = Weight / gravity

mass = 15/9.8

mass = 1.5306 kg

The density of the object can now be calculated using the relation

Density = mass/volume

Density = 1.5306 kg / 2.589 × 10⁻⁴m³

Density = 5911.94 kg/m³

Mercury has the largest core relative to its total diameter of any planet in the solar system.

The planet's core is estimated to be about 2,200 kilometers (1,367 miles) in radius, making up about 85% of its total diameter. This large core is thought to be the result of a massive impact that stripped away much of the planet's outer layers early in its history.

The core is also much denser than the planet's mantle and crust, with a density of about 10.6 grams per cubic centimeter, which is nearly twice that of the mantle and crust. The core is believed to be largely composed of iron and nickel, and its high density suggests that it may contain a small amount of sulfur as well.

Answer:

F' = 64 F

Explanation:

The electric force between charges is given by :

\(F=\dfrac{kq_1q_2}{r^2}\)

Where

q₁ and q₂ are charges

r is the distance between charges

When  each charge is doubled and the distance between them is 1/4 its original magnitude such that,

q₁' = 2q₁, q₂' = 2q₂ and r' = (r/4)

New force,

\(F'=\dfrac{kq_1'q_2'}{r'^2}\)

Apply new values,

\(F'=\dfrac{k\times 2q_1\times 2q_2}{(\dfrac{r}{4})^2}\\\\=\dfrac{k\times 4q_1q_2}{\dfrac{r^2}{16}}\\\\=64\times \dfrac{kq_1q_2}{r^2}\\\\=64F\)

So, the new force becomes 64 times the initial force.

Potential Energy is the energy that an object has stored in relation to its position in space.

One sort of potential energy is gravitational potential energy, which is equal to the product of the object's mass (m), the gravitational acceleration (g), and the object's height (h) as measured in relation to the ground's surface (the body).

You may determine the amount of energy that an elevated object has stored in it using a potential energy calculator.

Because it pertains to the energy that an object stores as a result of its vertical position or height, the full term of this effect is gravitational potential energy.

Therefore, Potential Energy is the energy that an object has stored in relation to its position in space.

The tension in the string if a rod PR is balanced on a pivot at the end R while a string is used to support the rod at P is 6 N

Moment = Force * Perpendicular Distance

Let us consider the pivot side be initial point,

Since the rod is balanced,

CM = ACM

CM = Clockwise moment

ACM = Anticlockwise moment

F = 9 N

PQ = 15 cm = 0.15 m

QR = 30 cm = 0.3 m

PR = PQ + QR

PR = 0.15 + 0.3

PR = 0.45 m

CM = W * QR

CM = 9 * 30

CM = 2.70 N m

ACM = T * PR

ACM = 0.45 T N m

2.70 = 0.45 T

Therefore, based on the estimated duration of a galactic year, Earth has been around for approximately 18.4 to 20.4 galactic ye

A "galactic year" refers to the time it takes for our solar system to complete one orbit around the Milky Way galaxy. The exact duration of a galactic year is not precisely determined due to various factors, such as the varying speeds of stars within the galaxy. However, it is estimated to be roughly 225-250 million years.

To calculate the number of galactic years Earth has been around based on the age of the solar system (4.6 billion years), we can divide the age of the solar system by the estimated duration of a galactic year:

Number of Galactic Years = Age of the Solar System ÷ Duration of a Galactic Year

Number of Galactic Years = 4.6 billion years ÷ 225-250 million years

Number of Galactic Years ≈ 18.4 to 20.4 galactic years

Therefore, based on the estimated duration of a galactic year, Earth has been around for approximately 18.4 to 20.4 galactic years.
