Answer:
The time that will pass between the feeling and hearing the explosion is 2,86 secs
Explanation:
First, let's calculate the time that the wave takes to travel until the actors feel the explosion:
Now, the time that pass while the actors hear the sound is:
<em>(Remember that the sound speed in the air is 340 m/s on average)</em>
So, the time between the feeling and hearing is 3,23 - 0,37 = 2,86 secs
Answer:
physics,chemistry,biology,astronomy and earht sciences
principles of science are integrity of knowledge honesty,collegiality(cooperation between colleagues) objectivity and openness
examples of science are actually branches of science so those are biology,mathematics,chemistry and physics etc
science is importent to provide our basic needs and to improve our living standard.It makes our life much easier by providing different technologies.It helps in the diagnosing and treatment of a disease
Answer: A
Explanation: because The kinetic energy of a moving object is directly proportional to its mass and directly proportional to the square of its velocity. The kinetic energy of an object can be changed by doing work on the object.
Answer:
General circulation model.
Explanation:
A general circulation model (GCM) is a type of climate model that employs a mathematical model of the general circulation of a planetary atmosphere or ocean. GCM uses the Navier–Stokes equations on a rotating sphere with thermodynamic terms for various energy sources (radiation, latent heat). These equations are the basic equations for computer programs used to simulate the Earth's atmosphere or oceans.
12/24=4x3/8x3
=4/8
4/8 is not correct ans it is less than 5/8
B) 3/4
multiply and divide it by 2 so the denominator should be equal to 8
3x2/4x2=6/8
6/8 is greater that 5/8 hence b is correct option
C)15/24=5/8 which is equalt to 5/8 hence it is not correct answer
D)4/12=1/3 it is also less than 5/8
