8th grade energy question - Need help quick please ! <3 I can give brainliest if answer is good :)

Answer:2.744

Explanation:

V= S^3

if the length of one side of cube is 1.4 cm
V= 1.4^3

V=2.744cm^3 or 2744mm^3

(It looks 1.4 to me tho)

The magnitude of  the metric volume of the cube  is 2.744 cubic centimeter.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Finding an object's volume can help us calculate the quantity needed to fill it, such as the volume of water needed to fill a bottle, aquarium, or water tank.

According to the picture:

Length of each sides of the cube is: a = 1.4 cm.

We have to fine: volume of the metric cube: V =?

We know that: volume of a cube is given by:

V = a³

⇒ V = 1.4³ cm³ = 2.744 cm³

Hence, magnitude of  the metric volume of the cube  is 2.744 cubic centimeter.

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.

Answer: Because they all share the same square root

Explanation:

Answer:

Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.

Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)

Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.

2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.

3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.

The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.

Answer:

Greg's acceleration will decreace faster than Karissa will.

Explanation:

If Greg pushed off with less force and Karissa pushes off with more and they weigh the same Greg slows down before Karissa does. I hope this helped. :)

Karissa's acceleration is  is greater than Greg's acceleration.

The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.

A spring balance can be used to calculate the Force. The Newton is the SI unit of force.

Let the mass of Greg and Karissa is m.

Force applied by Greg = 40 Newton.

Force applied by Karissa = 80 Newton.

From Newton's second law of motion, we know that:

Force = mass × acceleration

Acceleration = force/mass

Hence, Greg's acceleration is = 40/m m/s²

Karissa's acceleration is = 80/m m/s²

As 80 > 40; 80/m > 40/m

So,  Karissa's acceleration is  is greater than Greg's acceleration.

Answer:One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm.

Explanation:The majority of radiation from the Sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.

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

Net Force is the force which is the sum of all the forces acting on object i.e. pushing of pulling.

Net Force:

1)   4N (net force is 4N to the left)

2)  2 - 7 = -5N (net force is 5N to the left)

3)  4 - 4 = 0  (net force Zero)

4)  6 + 3 = 9N (net force is 9N to the right)

5)  4 - 8 = -4N (net force is 4N to the left)

6)  4 - 5 = -1N (net force is 1N to the left)

7)  -3 - 3 = -6N (net force is 6N to the left)

8)  2 + 4 - 5 = 1N (net force is 1N to the right)

9)  3 - 6 = -3N (net force is 3N to the left)

10.  4 + 4 - 7 - 1N (net force is 1N to the right)  

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.  

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km  

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, \(\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr\)

v = 1463.4 Km/hr
