4. A sledgehammer has a mass of 5 kilograms. What net force will a person need to apply to accelerate the sledgehammer to 5 m/s^2? Be sure to include units in your final answer (spell out the word).

Answers

Answer 1

Answer:The force that the person needs to apply to accelerate the sledgehammer is 14N.

What is a Force?

A force is an influence that can cause an object's motion to alter. A force can cause a mass item to change its velocity, or accelerate. Intuitively, force may be characterized as a push or a pull. A force is a vector quantity since it has both magnitude and direction. Its SI unit is Newton.

Force = Mass × Acceleration

Given that the mass of the sledgehammer is 3.5 kgs, the sledgehammer is needed to be accelerated at a rate of 4 m/sec².

Mass = 3.5 kgs

Acceleration = 4 m/sec²

Now, the net force that the person needs to apply to accelerate the "sledgehammer" at a rate of 4.0 m/sec² is,

Force = Mass × Acceleration

= 3.5 kg × 4 m/sec²

= 14 N

Hence, the force that the person needs to apply to accelerate the sledgehammer is 14N.

Answers

Answer:

The offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Explanation:

If there was a disease (as an example) that negatively effected both organisms that reproduce asexually and sexually, the organisms that reproduce asexually would have a disadvantage. Offspring of the organisms that reproduce sexually contain the genetic material of both parents. This would lead to a higher chance of the ability to adapt to any changes, or even a chance of being immune to that disease. However, offspring of the organisms that reproduce asexually are only replicates of the parent. This means that the asexually produced offspring and the parent organism could be harmed more than the sexually produced offspring and parent organism. The organism would have reduced abilities to adapt according to the changes in the enviroment.

The major disadvantage for organisms that reproduce asexually is option 4 that the offspring are genetically identical to each other, which reduces their ability to adapt to any changes in the environment.

Asexual reproduction is a type of reproduction where only a single parent is involved in creating offspring. The offspring reproduced are genetically identical to the parent. while this form of reproduction has many advantages including rapid and quick reproduction, it posses some major drawbacks as well.

As the genetic diversity is absent in asexual reproduction, adapting and surviving in the dynamic environment is tough for the offspring. Difficulty in catching up with the changing circumstances can sometimes lead to harm to upcoming species.

Which of the following equations follows the Law of Conservation of Mass?

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

Answers

Answer: C2H4 + 3O2 > 2CO2 + 2H2O

Explanation:

The law of conservation of mass has been given as the mass cannot be created nor be destroyed in a chemical reaction. The law of conservation of mass has equal weight of the reactants and the products.

The mass of following reactions can be given as:

28 g + 3(32)g = 2(44)g + 2(18)g Mass

124 g = 124 g

Thus, the reaction follows the law of conservation of mass.

12g + 4(2)g = 16g

20g = 16g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

3(18) = 3(2) + 3(32)

54g = 102g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

2(23) + 36.5 = 58.5 g

81.5g = 58.5g

The reactant and product mass has not been equal, thus not follows the law of conservation of mass.

The reaction that has been following the law of conservation of mass has been reaction 1. Thus, option 3 is correct.

2Na + Cl > NaCl

C + 4H2 > CH4

C2H4 + 3O2 > 2CO2 + 2H2O

3H2O > 3H2 + 3O2

C2H4 + 3O2 > 2CO2 + 2H2O

The mass of the following reactions can be given:

28 g + 3(32)g = 2(44)g + 2(18)g Mass

124 g = 124 g

Thus, the reaction follows the law of conservation of mass.

The mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
