Answer:
2. Wavelength
Explanation:
When a photon collides with an electron and is deflected, the photon’s wavelength decreases.
When photon gained energy by the collision of the electron. Its energy and frequency will be increased and its wavelength will be decreased.
Answer:
1. Frequency
Explanation:
When a photon collides with an electron, the effect of it is called Compton scattering, where the photons interact with the electron, losing momentum and therefore increase in wavelength and a decrease in frequency.
The speed of electrons striking the anode is increased, the density of the emitted x-rays increases.
Answer: Option 2
Explanation:
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.
In analog sound transmission, information is translated in electric pulses. In digital sound transmission, information is translated to binary codes of zero and one.
Explanation:
Answer: W = 294 J
Explanation: Solution:
Work is expressed as the product of force and the distance of the object.
W = Fd where F = mg
W= Fd
= mg d
= 15 kg ( 9.8 m/s²) ( 2m )
= 294 J
Answer:
Explanation:
When the velocity of an object changes, it would experience an impulse. If the mass of the object stays the same, and that the object moves along a line, the value of the impulse would be:
, where
On the other hand, the change in the object's velocity can be found with the equation:
.
Note that if is in

Answer: v = 20 m/s
Explanation: Solution:
Use the formula of Kinetic Energy and derive for v:
KE = 1/2 mv²
To find v:
v = √ 2 KE / m
= √ 2 ( 100000 J ) / 500 kg
= √ 400 m/s
= 20 m/s
Answer:
when u put ur mouth on the thermometer it checks the heat of your mouth because the whole body has the same tempature so just by the te,p of your mouth it can tell ur body tempature
Explanation:
The average speed of rocket in km/h is 40000 km/h and in m/s is 11111 m/s.
Explanation:
As the rocket is launched into outer space, the distance is given as 240000 km during 6 h. So the average speed will be the sum of initial speed and final speed.
As initially, the speed of rocket will be zero when it is at rest. And when it reaches the final speed, it had covered 240000 km in 6 hr.
So final speed is given by,
Thus the average speed will be same as the final speed since the initial speed and time is zero.
Average speed =40000 km/h.
In order to represent it in m/s, we get average speed =
So the average speed of rocket in km/h is 40000 km/h and in m/s is 11111 m/s.
Answer:
In essence, optical lenses bend and focus light, known as refraction. Prism lenses, however, refract light a bit differently. ... Light passing through a prism will bend towards the base, while the image of the object viewed with the prism moves toward the peak.
