A cup of sugar has a volume of 237ml . What is the mass of the cop of sugar if the density of sugar is 1.59g/ml?

Answers

Answer 1

Answer:

v=237ml m=? density(rho) = 1.59 g/ml

density = mass/volum

mass= (density)(volume)

m=(1.59)(237)

m=376.83g

Elements in the periodic table are arranged in the increasing order of their atomic number.

An atom will contain equal amount of protons and electrons. If two elements are in same period of periodic table then these elements will have same number of electrons.

Helium is one of the seven elements which are called as noble gases. This gas is odorless, tasteless and colorless which makes it unique from other elements.

It has two valence electrons while atoms of other elements in the group have 8 valence electrons.

Lithium has one valence electron, while calcium atom has 2 valence electrons.

The highest level of energy is due valence electrons of an atom. The correct answer is Lithium.

Fluorine element has 9 electrons. There are 2 electrons in the first energy level and seven electrons in the second energy level.

A body weights 50 N in air and 45 N when wholly immersed in water calculate (i) the loss in weight of the body in water (ii) the upthrust on the body. (iii) volume of the body.

Answers

Answer:

[tex]difference \: in \: weight = 150n - 100n = 50n[/tex]

Now,buyantant force

[tex]difference \: in \: weight \: = volume(body) \times density \: of \: water \: \times g[/tex]

so;

[tex]50 = {v}^{b} \times 1 \times {10}^{3} \times 9.8m {s}^{2}[/tex]

[tex] {v}^{b} = \frac{50}{1000 } \times 9.8[/tex]

[tex] = \frac{50}{9800} [/tex]

[tex] = 0.0051[/tex]

Now,

[tex]mass \: in \: air \: = 150n = \frac{150}{9.8kg} [/tex]

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

[tex] = \frac{150}{0.0051} \times 9.8 \\ x = 3000[/tex]

And now,

[tex]specific \: density \: = \frac{density of \: the \: body}{density \: of \: water} [/tex]

[tex] = \frac{3000}{1000} [/tex]

[tex] = 3[/tex]

Hence that,specific density of a given body is 3

Calculate the sum of the following numbers to the appropriate number of significant figures.

32.567 + 135.0 + 1.4567

Answers

Answer:

The answer is 169.0.

Explanation:

For addition and subtraction problems with significant figures, the answer should be rounded to the same number of decimal places as the measurement with the least number of decimal places.

Rules for Significant Figures:

All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4, and 5).Zeros appearing between two non-zero digits (trapped zeros) are significant. Example: 101.12 has five significant figures: 1, 0, 1, 1, and 2.Leading zeros (zeros before non-zero numbers) are not significant. For example, 0.00052 has two significant figures: 5 and 2.Trailing zeros (zeros after non-zero numbers) in a number without a decimal are generally not significant. For example, 400 has only one significant figure (4).Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0, and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.The number 0 has one significant figure. Therefore, any zeros after the decimal point are also significant. Example: 0.00 has three significant figures.Any numbers in scientific notation are considered significant. For example, 4.300 x 10-4 has 4 significant figures.

Explanation:

A car of mass 900 Kg is moving with a velocity of 10 m/s. It is brought to rest at 25 m distance by applying the brakes. Calculate the acceleration. Why is it negative? How much force is required to stop the car?

Answers

Answer:

Assumption: the acceleration of this vehicle is constant until it comes to a stop.

Acceleration: [tex](-2)\; \rm m\cdot s^{-2}[/tex].

The acceleration of this vehicle is negative because the velocity of this vehicle is decreasing over time.

Explanation:

Let [tex]u[/tex] denote the initial velocity of this vehicle. [tex]u = 10\; \rm m\cdot s^{-1}[/tex].Let [tex]v[/tex] denote the final velocity of this vehicle. [tex]v = 0\; \rm m\cdot s^{-1}[/tex] as the vehicle has come to a stop.Let [tex]x[/tex] denote the displacement of this vehicle. [tex]x = 25\; \rm m[/tex].Let [tex]a[/tex] denote the acceleration of this vehicle. The value of [tex]a\![/tex] needs to be found.

Assume that the acceleration of this vehicle, [tex]a[/tex], is constant. The SUVAT equations would apply.

The time [tex]t[/tex] required for braking is neither given nor required. Hence, make use of the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to relate [tex]u[/tex], [tex]v[/tex], [tex]a[/tex], and [tex]x\![/tex].

Rearrange this equation to find an expression for [tex]a[/tex], the acceleration of this vehicle:

[tex]\begin{aligned}a &= \frac{v^{2} - u^{2}}{2\, x} \\ &= \frac{(0\; \rm m\cdot s^{-1})^{2} - (10\; \rm m \cdot s^{-1})^{2}}{2\times (25\; \rm m)} \\ &= \frac{0^{2} - 10^{2}}{2 \times 25}\; \rm m \cdot s^{-2} \\ &= -2\; \rm m\cdot s^{-2}\end{aligned}[/tex].

When the rate of change of a value is greater than [tex]0[/tex], that value would become larger over time.When the rate of change of a value is equal to [tex]0[/tex], that value would be constant.When the rate of change of a value is smaller than [tex]0[/tex], that value would become smaller over time.

Acceleration is the rate at which velocity changes over time.

The velocity of the vehicle in this question is getting smaller over time. Hence, the rate of change of the velocity of this vehicle (that is, the acceleration of this vehicle) would be a negative number.

Which of the following is true about scientific laws?

Answers

Answer:

40m

Explanation:

Your total displacement would be 40m! Let me explain.

Going 30m north adds 30 to 0... so your total right now is 30m.

if you turn around and walk 10 m you have to add that 10 to the 30.

so your total displacement is 40m.

Likewise, his wife, Martha Washington, could also be considered the "Mother of America," as demonstrated by her roles as the general's wife and the first lady.During the American Revolution, Martha Washington earned the title of "Mother of America" for her caring nature as the general's wife. She was also very brave. Despite the danger of kidnapping, Martha refused to abandon her home, Mount Vernon, in Virginia. When Martha did leave the plantation for periods of time, she traveled to the military camps where Washington was staying. First, Martha had to be vaccinated so that she would not suffer from smallpox. Once she was inoculated, Martha made the risky trip to camp. British and American soldiers roamed the countryside, and capture was a real possibility. Nevertheless, Martha arrived at each winter camp. She acted as confidant and secretary to George Washington, who believed that her presence was crucial. She encouraged the soldiers, helped their wives, and comforted those who were wounded. One of her key roles was also to entertain important visitors to the camp. Occasionally, Martha Washington even represented George at events he could not attend. Martha used her position to contribute to fundraising efforts for military supplies in 1780 and knit socks for the soldiers herself. Overall, her care and attention to others' needs made her the "Mother of America" during the American Revolution.What evidence does the author use to support the idea that Martha Washington should be considered the "Mother of America"?A. British and American soldiers roamed the countryside, and capture was a real possibility. it is not B.C. First, Martha had to be vaccinated so that she would not suffer from smallpox.D.
