If a can of soup 150 g mass and 0.75g/ cm^3 density what’s the volume

Answers

Answer:

The answer is 200 cm³

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

[tex]volume = \frac{mass}{density}\\[/tex]

From the question

mass = 150 g

density = 0.75 g/cm³

We have

[tex]volume = \frac{150}{0.75} \\ [/tex]

We have the final answer as

200 cm³

O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s

Answers

Answer:

The answer is option D

Explanation:

To find the speed given the kinetic energy and mass we use the formula

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

where

m is the mass

v is the speed

From the question

KE = 15 J

m = 2.3 kg

We have

[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]

We have the final answer as

3.6 m/s

The mass of an atom Is found by adding Its protons and .The electric charge of an atom Is found by adding the charges carried by Its protons and .​

Answers

Answer: the 1st answer is neutrons and i think the 2nd is nucleus

Explanation:

The mass of an atom is found by adding its protons and neutrons. The electric charge of an atom is found by adding the charges of its protons and electrons.

What is atomic mass?

The atomic mass of an element is the total number of protons and the number of neutrons carried by one atom of that element. The atomic mass of an element is usually expressed in grams or a.m.u.

The atomic mass of an element = No. of protons + No. of neutrons

or

The atomic mass of an element = No. of electrons + No. of neutrons

The atomic number gives us information about how many protons are inside the nucleus of the atom. Elements are recognized by the number of protons in the nucleus. Neutrons are uncharged elementary or subatomic particles that are stable when bound in an atomic nucleus.

As the electrons and protons are charged particles in an atom, therefore, the sum of the charge carried by them is equal to the electrical charge of the atom.

For a neutral atom, the number of protons present in an atom is always equal to the number of electrons.

Square the following numbers 4,6,13,10 Passage 1: Excerpt from Will Yellow School Buses Soon Become Rolling Ads?1 Tight school budgets could soon translate into Missouri school districts selling ad space on yellow school buses.2 Missouri state Rep. T.J. Berry, R-Kearney, says his billHB 224isnt a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.3 Every single school district has had to deal with budget concerns, Berry said last week. And generally speaking, the way they have had to deal with those has been cuts or tax increases.4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.6 There is no such thing as free money, said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. There are real costs to this: the price of selling out your students to advertisers.7 Students dont need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers present a safety problem around school buses that cannot be ignored, the group said in its position paper.9 National studies have shown that anything that diverts a drivers attention from the road can pose a hazard, opponents say.10 And a big yellow bus doesnt distract? Berry asked.11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.12 Berry said the bill would limit the types of advertising that would be allowed.13 The regulations would prohibit ads that contain obscene or sexual material, or messages associated with gambling, tobacco products, alcohol, and political campaigns or causes. The ads could not promote drug use or any illegal activity or antisocial behavior. They cant contain harmful, discriminatory, false, misleading or deceptive messages.14 There are a lot of safeguards being built in, he said.15 Berry emphasized that the space reserved for the ads would be very limited, meaning toward the back of the bus.16 By 2012, nine statesArizona, Colorado, Massachusetts, Nevada, New Jersey, New Mexico, Tennessee, Texas and Utahpermitted advertising on the exterior of school buses, according to the Campaign for a Commercial-Free Childhood. Several, including Missouri, considered it last year.17 The bill made it out of the Missouri House last year but did not clear the Senate, Berry said. He acknowledged that the idea was very controversial.(questions)In Passage 1, how does the author compare the issues of tax increases and advertising on buses?A)They are both actions that require safeguards.B)They are both issues of controversy in school districts.C)They are both possible approaches to dealing with budgetary concerns.D)They are both present problems that cannot be ignored by state representatives.
