The speed of electrons striking the anode is increased, the density of the emitted x-rays increases.
Answer: Option 2
<u>Explanation:</u>
Whenever electrons are made to be incident on any anode, they will be interacting with the surface atoms of anode. So these interaction will lead to excitation of electrons of the surface atoms of the anode.
Thus when the excited electron will come back to ground state, it will emit x-rays. Thus, on increasing the speed of the striking electrons, it will gain the property of interacting with larger amount of surface atoms leading to increase in the emission of X-rays .
Thus, this increase in the emission of X-rays will lead to increase in the density of X-ray. So the speed of electrons striking the anode is increased, the density of the emitted x-rays increases.
Answer:
θ = 13.16 °
Explanation:
Lets take mass of child = m
Initial velocity ,u= 1.1 m/s
Final velocity ,v=3.7 m/s
d= 22.5 m
The force due to gravity along the incline plane = m g sinθ
The friction force = (m g)/5
Now from work power energy
We know that
work done by all forces = change in kinetic energy
( m g sinθ - (m g)/5 ) d = 1/2 m v² - 1/2 m u²
(2 g sinθ - ( 2 g)/5 ) d = v² - u²
take g = 10 m/s²
(20 sinθ - ( 20)/5 ) 22.5 = 3.7² - 1.1²
20 sinθ - 4 =12.48/22.5
θ = 13.16 °
Answer:
7.5 x 10⁻⁸N
Explanation:
Given parameters:
Mass 1 = 60kg
Mass 2 = 75kg
Distance between the bodies = 2m
Unknown:
Gravitational fore = ?
Solution:
The gravitational force between the two bodies can be derived using;
F = 
G is the universal gravitation constant = 6.67 x 10⁻¹¹m³kg⁻¹s⁻²
Insert the parameters and solve;
F = 
= 7.5 x 10⁻⁸N
Carbon is pulled from the atmosphere in the carbon cycle through the process of photosynthesis. Details about photosynthesis can be found below.
<h3>What is photosynthesis?</h3>
Photosynthesis is the process whereby green plants obtain their nutrition by utilizing energy from sunlight.
Green plants absorb carbon in the form of carbon dioxide from the atmosphere and use it in the photosynthetic process.
This means that one way that carbon is removed from the atmosphere during the carbon cycle is through photosynthesis.
