Answer:

I think its A & C

Explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.

Elements located in the vertical column of the periodic table are of the same group and have similar chemical properties, therefore the correct answer is option A and option C.

The total number of protons present in an atom is known as the atomic number of that atom.

While the atomic mass of an atom is the sum of the total number of protons and the number of neutrons present inside any atom.

The element belonging to the same group have approximately similar chemical behavior while on the other hand element belonging to the same period would have the same outermost shell.

The correct response is option A and option C because elements included in the vertical column of the periodic table belong to the same group and have comparable chemical characteristics.

Given :

A bird flies 6 km east, then 4 km west.

To Find :

the total distance traveled and displacement after this flight.

Solution :

a)

We know , total distance is the amount of how much ground an object has covered .

Distance = 6+4 km = 10 km .

b )

Displacement is the shortest distance from one point to another .

Now , here the object first move 6 km east then moves 4 km west .

So , his distance from the starting position is :

Displacement = 6 - 4 km = 2 km .

Hence , this is the required solution .

Answer:50,50,69

Explanation:I just did it

Multiply field strength (N/kg) by mass (kg) to get weight (N)

At the start, the car is carrying

4.7 kg * (9.8 N/kg) = 46.06 N

of fuel.

At the end, it is carrying

3.0 kg * (9.8 N/kg) = 29.4 N.

Assuming the car remains completely intact, its weight was reduced by

46.06 N - 29.4 N = 16.66 N.

Answer:

С. 10.41 Ampere

Explanation:

Given that,

Power, P = 125 watts

Voltage, V = 12 volts

We need to find current. Power in terms of current and voltage is given by :

P = VI, I = current

[tex]I=\dfrac{P}{V}\\\\I=\dfrac{125\ W}{12\ V}\\\\I=10.41\ A[/tex]

Explanation:I just took the test on Edgenuity

Explanation:

it means its velocity and acceleration is constant. And there is no change in displacement , so the object is not moving.

Explanation:

v = u + at

v = 5 + 2.5 * 5

V ( final velocity after 5 sec) = 17.5 m/s

Answer:

The average speed will be "1038 mph".

Explanation:

Period for one revolution is:

T = 24 hours

  = 86,400 sec

x = c = 2πr

The given values is:

r = 6.38×10⁶ m

Now,

⇒  [tex]T=\frac{2 \pi r}{v}[/tex]

Or,

⇒  [tex]v=\frac{2 \pi r}{T}[/tex]

On substituting the values, we get

       [tex]=\frac{2 \pi (6.38\times 10^6)}{86,400}[/tex]

       [tex]=464 \ min/sec[/tex]

       [tex]=(464 \frac{min}{sec}) (\frac{3600 \ sec}{1 \ hour} )(\frac{1 \ mi}{1609 \ m} )[/tex]

       [tex]=1038 \ mph[/tex]

Answer:

s = 92.36 m

Explanation:

The distance covered by an object moving with uniform speed is given by the following formula:

s = vt

where,

s = distance covered by car during the time when driver was distracted in texting = ?

v = uniform speed of car = (95 km/h)(1 h/3600 s)(1000 m/1 km) = 26.39 m/s

t = time taken by the driver for texting = 3.5 s

Therefore, using these values in equation, we get:

s = (26.39 m/s)(3.5 s)

s = 92.36 m

Given :

You drive 200 miles in 3 hours before stopping for lunch and gas. After lunch you  travel 250 miles in an hour and a half.

To Find :

Average speed.

Solution :

We know, average speed is given by :

[tex]v=\dfrac{\text{Total distance covered}}{\text{Total time taken}}\\\\v=\dfrac{200+250}{3+1.5}\ miles/hr\\\\v=\dfrac{450}{4.5}\ miles/hr\\\\v=100\ miles/hr[/tex]

Therefore, average speed of the journey is 100 miles/hr.

Hence, this is the required solution.

First find the diameter of each.

Jupiter’s diameter is 86,881 mi.

Earth’s diameter is 7,917.5 mi.

Then divide those two.

Rounded, Jupiter is 11 times larger.

unrounded: 10.9732870224186927691821913482791285127

Finding out how large something is compared to something can be done by dividing.

For example I have two dogs. One dog is 3 feet tall. The other is 2 feet tall. How much taller is dog one? Dog one is 1.5 times larger because 3/2 = 1.5 AND 2 x 1.5 = 3.

So for this case multiplying Earth’s diameter by 10.9732870224186927691821913482791285127 will give you Jupiter’s diameter.

Answer: 1 2 5

Explanation:

Galileo Galilei, an Italian physicist, is credited with being the first to calculate speed by dividing it by the distance traveled and the time required. Galileo defined speed as the distance covered in a predetermined period of time. Thus option A, B. E is correct.

Speed is determined by dividing the distance by the time. Calculating the units for speed requires knowledge of the units for both time and distance. Since the distance is measured in meters (m) and the time is measured in seconds, the units in this example will be meters per second (m/s) (s).

That is speed = distance time. Alternatively, you can calculate the time by dividing the distance traveled by the speed. You can figure out the third input if you know two of the inputs.

Therefore,  For instance, if a car drives 120 miles (ca. 193 km) in 2 hours, we may calculate the speed as 120 × 2 = 60 miles per hour (ca. 97 km/h).

Answer:

the percentage we have the fraction between the error and the magnitude,

Explanation:

When absolute error is used, it is a value that remains constant regardless of the magnitude of the measurement, for large measurements it can represent great accuracy, but for small measurements the accuracy may be low, for example> if we use a tape measure with error of Dx = 0.1 cm if the measurement is 1 meter this error is acceptable, but if the measurement is 1 cm the error is too big.

When we use the percentage we have the fraction between the error and the magnitude, so if this relationship is small the measure is very tight and but if the relationship is high the measure has little pressure, for example

           Δx = 1 cm = 0.01 m

          % = 0.01 / 1   100 = 1%

          % = 0.01 / 0.01 100 = 100%

therefore the precision of the measurement is known the percentage error

Answer:

Explanation:

No, not any of these substance will float in Methanol , simply because Methanol has a density of 0.79 g, if you put any substance that weighs more than 0.79 g, it will sink, it all depends on the weight if it is more or less than methanol  

2: D=m/v

D=135/50 = 2.7 g/cm³ ( Aluminum)

D=M/V

if two objects has the same mass but one has larger volume, then te one with larger volume has less density

example : 2 objects

mass of both=350

volume of the first one=500 and  the other 750

D1=M1/V1 = 350/500 =0.7

D2 = M2/V2 = 350/750 = 0.4666

D1 is larger than D2( with larger volume )
