to what temperature must a given mass of nitrogen at zero degrees be heated so both its volume and pressure will be doubled​
Talja [164]

Answer:

0 degrees Celsius is 273 degrees Kelvin. As both pressure and volume are proportional to absolute temperature, in order to double both you would need to quadruple the temperature. I.e. 273 X 4 = 1092 Kelvin = 819 Celsius

How do the linear equation and quadratic equation are differ? What do we suffer on earth? What if we would live on the moon /sun
Aleksandr [31]

A quadratic equation is a parabola and a linear equation is a straight line.

  • Quadratic Equation is an equation in which the power of variable mostly x is two.
  • Standard quadratic equation is  ax^{2} +bx+c=0
  • Any linear equation have form like y=mx+c
  • The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
  • Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
  • Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.

First, you will investigate purely vertical motion. The kinematics equation for vertical motion (ignoring air resistance) is giv
AlladinOne [14]

Answer: It takes 2.85 seconds.

Explanation: according to the question, the kinematics equation for vertical motion is

y(t) = y_{0} + v_{0} .t - \frac{1}{2} .gt^{2}

y₀ is the initial postion and equals 0 because it is fired at ground level;

v₀ is the initial speed and eqauls 14m/s;

g is gravity and it is 9.8m/s²;

y(t) is the final position and equals 0 because it is when the pumpkin hits the ground;

Rewriting the equation, we have:

0 + 14t - \frac{1}{2}.9.8.t^{2} = 0

14t - 4.9t² = 0

t(14 - 4.9t) = 0

For this equation to be zero,

t = 0 or

14 - 4.9t = 0

- 4.9t = - 14

t = \frac{14}{4.9}

t = 2.86

It takes 2.86 seconds for the pumpkin to hit the ground.

What is meant by magnetic field
Darina [25.2K]

Answer:

a. Magnetic field is a location of a vector field around an electric current or magnet formed due to moving electric charges, or magnetic material and has a magnetic effect and exerts a force on other magnetic materials, electric current, and electric charges. The Earth's magnetic field that has the effect of turning a compass needle is an example of a magnetic field

b. The number of turns of the coil, N, in Diagram 1.1 > The number of turns of the coil, N, in Diagram 1.2

The pattern of the iron filings in Diagram 1.1 are closer with less space in between than the pattern of iron filings in Diagram 1.2

The angle of deflection of the ammeter pointer in Diagram 1.1 will be > The angle of deflection of the ammeter pointer in Diagram 1.2, given that the number of turns and current are inversely proportional

c. i. The pattern of the iron filings will have rings which are more closely arranged to each other as the strength of the magnetic field is increased

ii. As the number of turns is increased, the magnetic field is increased
