Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

Answer:

I think C is the correct answer.

Explanation:

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Answer:  D) Round

Explanation:

Phenotype is what the plant looks like, so with a genotype of Rr, the plant would be round.  R (round) is dominant over r (wrinkled).  The plant is heterozygous round.

You can't do a Punnett square because you don't know the genotypes of the parent plants.

Explanation: Its a type of white blood cell that moves by amoeboid

Newton's first law states that unless acted with by an external force, the dinnerware will remain immobile. The horizontal force acting on the objects on the table in this example is the frictional force between them and the table cloth, which sets them in motion.

According to Newton's second law, the force required to accelerate the tableware is proportional to the rate of acceleration. When the tablecloth is slowly pushed, the dinnerware adjusts to fit the modest rate of acceleration and moves with it. When the tableware is pulled swiftly, it needs to accelerate at a faster pace to keep up; but, the effort required to do so is larger than the frictional force available, thus it lags behind. The tableware 'stays put' when the cloth is tugged quickly.''

This question covers one of the most enigmatic aspects of our universe! Inertia is the easy answer to your question. In other words, because of inertia, when you remove the table linen off a table full of dishes, the dishes stay put. Matter's inertia is a property that characterizes its resistance to change in motion. When you're jogging and try to turn, you'll find that the faster you go or the bigger you are, the more difficult it is to shift direction.

Other examples of inertia include the following. Another example of inertia is when you are riding in a car and the driver rounds a corner and you feel pushed toward the door or over to the driver.

The dishes' inertia comes into play when the magician removes the cloth from underneath them.

The propensity of objects to resist changes in their state of motion is known as inertia. The dishes seek to preserve their original condition of rest when the fabric is quickly pulled because of inertia.

The dishes' and the cloth's friction is insufficient to rapidly overcome this inertia. As a result, the dishes initially hold in place before friction gradually takes over and causes them to slide.

Thus, the careful balance between inertia and friction results in this seemingly supernatural effect, producing a visually stunning illusion.

Curling is a sport in which players slide stones across a  distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side.  There are two  brigades. Each  platoon is trying to keep the other  platoon's  monuments down from the target by knocking their  monuments out of the way.

Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object."  This relates to the formula F =  ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Such forces often cause one object to speed up (gain momentum) and the other object to slow down (lose momentum). According to Newton's third law, the forces on the two objects are equal in magnitude.

Answer: C

50x3= 150 Hope this helps

Answer:

C

Explanation:

Using the distance formula: Distance = Rate x Time, we can plug in the value Distance = 50 mph x 3 which is 150 miles.

40g remains after an hour.

Answer:

a. Effort = 960 Newton

b. Mechanical advantage (M.A) = 0.625

c. Velocity ratio (V.R) = 1.67

Explanation:

Given the following data;

Load = 600 N

Length of crowbar = 200 cm

Length of load arm = 0.75 m

Conversion:

100 cm = 1 m

X cm = 0.75 m

Cross-multiplying, we have;

X = 0.75 * 100 = 75 cm

First of all, we would find the effort arm;

Effort arm = length of crow bar - length of load arm

Effort arm = 200 - 75

Effort arm = 125 cm

Next, we would determine the mechanical advantage (M.A) of the crow bar;

Substituting the values into the formula, we have;

M.A = 0.625

To find the effort of the crow bar;

Making "effort" the subject of formula, we have;

Effort = 960 Newton

Lastly, we would determine the velocity ratio (V.R);

V.R = 1.67

Answer:a. Effort = 960 Newton

b. Mechanical advantage (M.A) = 0.625

c. Velocity ratio (V.R) = 1.67

Explanation:

One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.

Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.

The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.

Answer:

It cannot be moving without any force pushing behind it as it is only slightly vibrating unless it is a liquid or a gas which in that case is consantly moving around.

Explanation:

The example of matter in the three states is brick in solid state, water in liquid state and oxygen gas in gaseous state.

1. Solid: A brick is a solid object that maintains a fixed shape and volume.

2. Liquid: A glass of water is a liquid that conforms to the shape of its container but maintains a definite volume.

3. Gas: Oxygen gas in the atmosphere is a gas that does not have a fixed shape or volume, filling the available space.

The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, such as an ice cube. Liquids have a definite volume but take the shape of their container, like water. Gases have neither a fixed shape nor volume and fill the entire space available to them, such as the air we breathe.

In summary, the states of matter describe the physical properties of substances based on the arrangement and movement of their particles, with solids having a fixed shape, liquids taking the shape of their container, and gases being free-flowing and filling all available space.

Solid: An object that keeps a constant shape and volume is a brick.

Thus, Liquid: A glass of water is a liquid that keeps a consistent volume while taking on the shape of its container. Gas: Oxygen gas fills the available space in the atmosphere and does not have a defined shape or volume.

Gas, liquid, and solid matter can exist in any combination. Solids, like an ice cube, have a set shape and volume.

Like water, liquids have a set capacity but adopt the shape of their container. Gases, like the air we breathe, have neither a set shape nor volume and fill all available space.

Thus, Solid: An object that keeps a constant shape and volume is a brick.
