Answer:

D is the answer

Explanation:

6.45×7.44= 47.98800

Which if we round of we get 48m

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

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:

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]

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.

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

Answer:

Explanation:

Wattage = E * I

E = 240

I = 0.24

Wattage = 240 * 0.24

Wattage = 57.6

Answer:

1) mass = force / acceleration

2) acceleration = force / mass

Explanation:

Part 1)

Force = Mass x Acceleration

Divide both sides by acceleration

force / acceleration = mass

mass = force / acceleration

Part 2)

Divide both sides by mass

force / mass = acceleration

acceleration = force / mass

Explanation:

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...

Answer:

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