Answer:
7. 1ml = 20 drops
325ml = 6500
( 325 x 20 = 6500)
there are 6500 drops in a pepsi can
8. not sure sorry ; (
9. 1 mile per hour = 88 feet per minute
45 miles per hour = 3960 feet per minute
( 88 x 45 = 3960)
there are 3960 feet per minute in 45 miles per hour
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.
Explanation:
Answer:
No, the acceleration is not always zero.
Explanation:
It does not mean that the acceleration of the particle is zero.
The velocity of wave is different from the velocity of particle.
The acceleration of wave is different from the acceleration of particle.
the acceleration of the particle is given by

where, w is the angular frequency and y is the displacement from the mean position.
So, the acceleration is zero at mean position only and it varies as the position changes.
Answer:
The energy of photon, 
Explanation:
It is given that,
Voltage of anode, 
We need to find the maximum energy of the photon of the x- ray radiation. The energy required to raise an electron through one volt is called electron volt.

e is charge of electron


So, the maximum energy of the x- ray radiation is
. Hence, this is the required solution.
