A cart has a mass of 35kg and a speed of 1.2m/s. What is its kinetic energy

Answers

Answer:

The answer is 25.2 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]KE = \frac{1}{2} m {v}^{2} \\ [/tex]

where

m is the mass

v is the velocity

From the question we have

[tex]KE = \frac{1}{2} \times 35 \times {1.2}^{2} \\ = 17.5 \times 1.44 [/tex]

We have the final answer as

25.2 J

Hope this helps you

Answer:

25.2 J

Explanation:

Using the kinetic energy formula:

KE = [tex]\frac{1}{2}[/tex]m v²

Plug in the given values:

KE = [tex]\frac{1}{2}[/tex] (35 kg) · (1.2 m/s)²

KE = [tex]\frac{1}{2}[/tex] (35) · 1.44

KE = 17.5 · 1.44

KE = 25.2 J

There is a kinetic energy of 25.2 Joules.

[Ne] 3s^ 2 3p^ 4 can someone tell me the element

Answers

Answer:

Sulpher

Explanation:

For this type of questions; calculate the total number of electrons so that you can identify the element from the periodic table.

Neon has 10 electrons. and from 3s^2 and 3p^4 there are 6 electrons.

So the total number of electrons is 16.

The element is Sulpher from group 6 of the periodic table

a student is using colored beads to make a model of aluminum sulfate, Al2(SO4)3.
Aluminum atoms are represented by green beads, sulfur atoms by blue beads, and
oxygen atoms by yellow beads. What combination of beads should the student use for
the model?

Answers

The combination of beads should the student use for  the model :2 green, 3 blue and 12 yellow

the modelFurther explanation

In the chemical formula of a compound there are numbers:

1. The number indicates the number of atoms written after the element symbol

2. The number after the parentheses represents the number multiplied by the number of atoms in parentheses.

3. The number before the chemical formula shows the number of molecules behind it, which is usually used in equations

To calculate the beads needed to make a model, we must count the number of atoms of the Al₂(SO₄)₃ molecule

In the Al₂ (SO₄) ₃ molecule there are 3 atoms : Al, S, and O

1. Number of Al atoms: 2 2. The number of atoms S = 3 x 1 = 3 3. The number of atoms O = 4 x 3 = 12

So the combination of beads

2 green(for Al), 3 blue(for S) and 12 yellow(for O)

Answer:

2 blue, 3 yellow, and 12 green

What type of bond is Cu and F Ionic or Covalent? ​

Answers

An ionic bond because it is between a non-metal and a metal. I hope this helps!

2. What type of bonding would be expected between the following atoms?
a. Li and F
c. I and Br
b. Cu and S
d. S and O

Answers

a.) covalent
c.) covalent
b.) ionic
d.) covalent

Considering the definition of covalent and ionic bond, the type of bonding that would be expected between the following atoms is:

Li and F: Ionic Bond I and Br: Covalent Bond Cu and S: Ionic Bond S and O: Covalent Bond

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.  

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Taking into account the previous definitions, it is first necessary to know if the elements are metallic or non-metallic:

Lithium Li: Metallic atoms Flour F: Non-metallic atoms Iodine I: Non-metallic atomsBromine Br: Non-metallic atomsCopper Cu: Metallic atoms Sulfur S: Non-metallic atoms Oxygen O: Non-metallic atoms

Now you can determine the type of bond of the following pairs of elements:

Li and F: Metallic atoms - Non-metallic atoms: Ionic Bond I and Br: Non-metallic atoms - Non-metallic atoms: Covalent Bond Cu and S: Metallic atoms - Non-metallic atoms: Ionic Bond S and O: Non-metallic atoms - Non-metallic atoms: Covalent Bond

WILL GIVE BRAINLIEST 1 The day of Josephine and Cora's campout had finally arrived. The two friends had been planning the campout for more than two weeks. They picked out a spot for the tent in Josephine's backyard. They chose the games they wanted to play. Now they were at the store with Josephine's dad buying camping food. "This campout is going to be perfect," Cora said as she dropped a bag of marshmallows into the cart. "We have the perfect tent, the perfect games, and the perfect food!"2 Just then a loud clap of thunder sounded outside. The wind whipped as a bright flash filled the dark sky.3 "But not the perfect weather," Cora moaned.4 "That was thunder and that means rain. Rain means no camping," Josephine groaned.5 "I guess we can stop shopping!" Cora snapped. She began taking food out of the cart.6 As Josephine's father placed the food back in the cart, he told the girls not to give up on their campout. They paid for the food and went back to Josephine's house to wait out the storm.7 At dinnertime the sky remained dark gray as the rain continued to pour down outside. The girls sat in silence while they ate. Cora looked out the window and said sadly, "I can't believe it's still raining. Our campout was supposed to be perfect."8 Josephine nodded as she looked from her plate to the window. Josephine's father told the girls that just because something seems impossible doesn't mean it can't happen. He told them to finish eating, go upstairs, and get ready for the campout.9 They looked out the window and wondered how they could still have a campout. How would they stay dry? How would Josephine's father build a fire with wet wood? It was not possible that they could camp in the backyard. Josephine and Cora gathered their sleeping bags and games anyway. They walked slowly down the stairs.10 When the girls got to the bottom of the steps, they smiled. Josephine's living room looked like a forest. The chairs and tables were gone, and potted plants took their place. A fire crackled in the fireplace. Strings of tiny lights glittered like fireflies on the walls. Best of all, the tent was set up in the middle of the room. Josephine and Cora were going to camp after all!11 Josephine and Cora learned that the rain didn't have to spoil their fun. They didn't need to be outside to camp. They didn't need a real campfire to cook hot dogs or marshmallows. Josephine and Cora's indoor campout was perfect because they didn't give up on it.Read the passage on the left to answer the following questions:3) Which sentence BEST describes the theme of this story?A) If you're hopeful, the weather could improve.
