The sleigh is being pulled with a force of 800N and has a mass of 200 Kg.
What is the acceleration in m/s/s?

Answers

Answer 1
The answer is 4 m/s/s
Answer 2

Answer:

a = 4m/s²

Explanation:

Given:

F = 800N

m = 200 kg

Unknown:

acceleration or a

Formula and solution:

a = F/m

a = 800 kg.m/s² ÷ 200 kg

Final Answer:

a = 4 m/s²

in the solution there's a two same unit and that is kg so the same unit will be cancelled and the rest is going to aapply in the answer that is 4 so if combine it the final answer is 4 m/s²

the answer is 4.



explanation:

A student lists some possible ways to investigate the transfer of kinetic energy using ice in a sample of water. The procedure would be best to investigate the transfer of kinetic energy is Determine temperature and mass of water. Put ice in water. Record the time for ice to melt. Therefore, option 4 is correct.

What do you mean by kinetic energy ?

The term kinetic energy is define as the energy of motion, observable as the movement of an object. The formula of kinetic energy is as follows:

Kinetic energy = 1/2 mv²

Kinetic energy exists in every moving object and particle. Kinetic energy is demonstrated by a person walking, a soaring baseball, a crumb falling from a table, and a charged particle in an electric field.

Kinetic energy is the energy held by a moving object. Kinetic energy exists in the earth's rotation around the sun, you walking down the street, and molecules moving in space.

Thus, option 4 is correct.

Explanation:

Answer:

A

Explanation:

X-Rays can reveal an objects temperature since temperature determines the wavelength of its radiation. The ________ the object, the _________ the wavelength is.

PLEASE HELP!

Answers

Answer: I think the answer is "hotter" the "bigger"

Explanation:

X-Rays can reveal an objects temperature since temperature determines the wavelength of its radiation. The HOTTER the object, the BIGGER the wavelength is because if tempeture determines wavelength then the hotter it is the bigger the wavelength would be and vice versa. Hopefully that helped. im not 100% sure.

What purpose would the sand serve?



FIRST ONE TO ANSWER CORRECTLY GETS BRAINLIEST!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Explanation:

Interesting fact...

Why are there differences between the cooling rates of sand and water? Sand cools off faster than water because sand is a solid. Water heats up slower and cools off slower than sand. Sand heats up faster and cools off faster than water.

As a variable and to count as land. As if you were at a beach, this sand would count as the sand that the sun would be beaming on. ^^

Answer:

Gravity

Explanation:

Because there this is lot of mass there is a force pulling mass to it, that is gravity.

Gravity!

The Sun's gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.

What is true about the force acting on the cars at the end of a roller coaster ride as they slow down right before stopping?

Answers

That the gravity dosent Change

The cars will slow down as a result of unbalanced forces and negative acceleration.

What is Inertia?

Inertia is the ability of an object to continue its current motion until and unless some external force causes its speed or direction to change. Inertia is described in the Newton's first law of Motion.

The cars are slowed due to negative acceleration of the object eventually to a stop, because of these unbalanced forces due to friction which are acting on them. The riders, which have inertia, are also acted on by the unbalanced forces throughout the ride causing them to change their state of motion.

1. Mass no.= protons+ neutrons,
Therefore, mass no. of sodium = 11 + 12 = 23

2. Total no. of electrons in a neutral sodium atom (has not reacted with anything, thus has not lost any electrons, thus is neutral) = Atomic no. = electron no. = 11

3. So as mass no. of magnesium is 24, and mass no. = protons+neutrons, and no. of protons is 12, then no. of neutrons= atomic no. - protons = 24-12= 12

4. Atomic no. = no. Of electrons= 13

5. Mass no. = protons+neutrons= 31
No. Of neutrons=16
Therefore, no. Of protons= Mass no. - neutrons= 31-16=15
Also- no. Of protons=no. Of electrons= 15 (another way to solve)
