Why does increasing the amount a greenhouse gas increase the temperature of a planet?

Greenhouse gass effects the increase of temperatures on Earth, which means plant temperature rises as well. the reason for the rise in temp. is due to the fact that the gass acts as a wall that doesn't allow heat to go through. So when greenhouse gass is applied to a plant the gas doesn't let the heat go through therefore raising the temperature.

Green houses gases like CO2, water vapour and methane, these gases traps heat in its structure, this is same like glass house in which infrared waves can only enter but after entering the waves will become polarisezed it will prevent waves going out and hence increrasing the temperature

Using a simple pendulum, we can measure. (a) Acceleration along a circle (b) Acceleration due to gravity (c) Frequency (d) None
zalisa [80]

Answer:

Option B is the correct answer.

Explanation:

Period of simple pendulum is given by the expression T=2\pi \sqrt{\frac{l}{g}}, where l is the length of pendulum and g is the acceleration due to gravity value.

So if we have a simple pendulum with length l we can find its period. Using the above formula we can calculate  acceleration due to gravity value of that place.

So using simple pendulum we can measure acceleration due to gravity value.

Option B is the correct answer.

A coin 15.0 mm in diameter is placed 15.0 cm from a spherical mirror. The coin's image is 5.0 mm in diameter and is erect. Is th
s344n2d4d5 [400]

Answer:

15 cm

Explanation:

h_{o} = Diameter of the coin = 15 mm

h_{i} = Diameter of the image of coin =  5 mm

d_{o} = distance of the coin from mirror = 15 cm

d_{i} = distance of the image of coin from mirror = ?

Using the equation

\frac{d_{i}}{d_{o}} = \frac{- h_{i}}{h_{o}}

\frac{d_{i}}{15} = \frac{- (5)}{15}

d_{i} = - 5 cm

R = radius of curvature

Using the mirror equation

\frac{1}{d_{o}} + \frac{1}{d_{i}} = \frac{2}{R}

\frac{1}{15} + \frac{1}{- 5} = \frac{2}{R}

R = - 15 cm

What is the velocity of a beam of electrons that go undeflected when passing through crossed electric and magnetic fields of mag
lana [24]

Answer:

v = 4.78 \times  {10}^{6} m {s}^{ - 1}

Explanation:

Since the electrons are undeflected,

Magnetic force = Electric force

evB = eE

v = E/B

v =  \frac{1.4 \times  {10}^{4} }{2.93 \times  {10}^{ - 3} } \\ = 4.78 \times  {10}^{6} m {s}^{ - 1}

A bicycle is moving from rest with a constant acceleration of 3 m/s^2 calculate the final velocity of the car if the distance mo
iragen [17]

Answer:

6m/s

Explanation:

  • Acclⁿ = 3m/s²
  • Displacement = 6m .
  • Initial velocity = 0m/s .
  • Final velocity = ?

We know that ,

\longrightarrow 2as = v² - u²

\longrightarrow 2 * 3m/s² * 6m = v² - (0)²

\longrightarrow v² = 36m²/s²

\longrightarrow v = √36 m²/s²

\longrightarrow v = 6m/s

Would a limestone building weather more rapidly in Homer, Alaska, or in Honolulu, Hawaii? Explain your reasoning.
Vinvika [58]
Hawaii for sure. 

Well, Hawaii is hot (most of the time I think) and Alaska is always freezing (or at least cold). So hawaii.
