Explanation:

distance is equal to speed over t therefore 36 divide by 4 is 10

Answer:

The larger the number of charges flowing through the wire,the larger is the current flowing in the wire.

Explanation:

if the wire is large then large amount of current flows through the circuit.but if the wire is small then a smaller amount of current will pass through.

Answer:

It's 2–

Explanation:

Usually, in ionic bonds, these elements will receive 2 electrons, so its ion will carry a 2– charge

The ionic charge its ion will carry will be 2-

An element is required to have 8 electrons in its outermost shell to assume it's full octet configuration.

The statement above of course excludes Hydrogen and helium which have only 1 and 2 electrons respectively.

An element with 6 Valence electrons would require 2 electrons to assume the full octet configuration.

As such, it is liable to accept 2 electrons from an electropositive element or group of elements to complete it's octet.

Therefore, accepting 2 electrons adds 2 negative charges and consequently, the ionic form of the element carries a 2- ionic charge

Explanation:

if the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on.

Answer:

So, if a body is taken to moon, the moon attracts the body with a force less as compared to the attraction force by the earth. Hence the weight decreases.

Answer:

In the formula, 'X' is the temperature value to be converted, 'UFP' is the upper fixed point and 'LFP' is the lower fixed point of the temperature scale

Explanation:

LFP means Lower fixed point and UFP means Upper fixed point. Explanation: There are different scales with different lower fixed point and upper fixed point to measure temperature but the distance between these scales is same in any table or scale considered.

Answer:

800 m

Explanation:

Acceleration (a) = Velocity (v) / Time(t)

a = (v-u) /t

where, v = final speed

u = initial speed

2m/s² = (40m/s - 0m/s)/t

that is, from rest is no speed.

2m/s² = (40m/s) /t

t = (40m/s)/2m/s²

t = 20 s

hence, the car has accelerated for 20 s.

From,

Velocity (v) = Displacement (d) /time(t)

displacement is the distance the car has travelled.

40m/s = d/20s

d = 40m/s × 20s

d = 800 m

Hi,

The man on the ground in standing position has more pressure. This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.

To the point, a man standing position on the ground had more pressure.

More is the area of contact, less is the pressure efforted.

Thank you...

Each atom within a specific element has the same number of protons, which determines its atomic number. The correct statement.

This is inaccurate because the atomic number of an element is determined by the number of protons in the nucleus of its atoms, not by the number of neutrons.

Each atom within a specific element has the same number of protons, which determines its atomic number. The atomic number of an element is a fundamental property that defines the element and its place on the periodic table.

The number of protons in the nucleus of an atom of that element. Neutrons, do affect the atom's mass and stability but do not determine their atomic number.

Answer:

Explanation:

one in which a positively charged nucleus is surrounded by one or more negatively charged electrons.

Answer:

Below

Explanation:

4. You can use this formula to calculate the acceleration of an object

     acceleration = velocity / elapsed time

Plugging our values in....

     acceleration = 1700 m/s / 25 s

                          = 68 m/s^2

5. You can use this formula to calculate the final velocity of an object

     finalvelocity = initialvelocity + (acceleration) (time)

Plugging our values in....

     finalvelocity = 1.5 m/s + (2.4 m/s^2) ( 3 seconds)

                         = 8.7 m/s

Hope this helps! Best of luck <3

Answer:

if the distance between them is halved then gravitational force will be doubled....

Answer:

Pressure is 1.96 × 10^12 Pa

Explanation:

[tex]{ \bf{pressure = \frac{force}{area} }}[/tex]

height = 4 cm = 0.04 m

density = 20 g/cm³ = 20,000 kg/m³

But for force:

[tex]{ \sf{force = mass \times acceleration}} \\ { \sf{force = ( \frac{density}{volume} ) \times acceleration}} \\ \\ { \sf{force = ( \frac{20000 }{0.04 {}^{3} }) \times 10 }} \\ \\ { \sf{force = 3.13 \times {10}^{9} \: newtons}}[/tex]

For area:

[tex]{ \sf{area = 0.04 \times 0.04 = 0.0016 \: m {}^{2} }}[/tex]

[tex] { \tt{pressure = \frac{3.13 \times {10}^{9} }{0.0016} }} \\ \\ = { \tt{1.96 \times {10}^{12} \: pascals}}[/tex]
