work done=446.9 J . so option (c) is correct.
Explanation:
the formula for work done is given by
W= F d
F= force= mg where m= mass and g= acceleration due to gravity
F= 3.8 (9.8)=37.24 J
so W=37.24 (12)
W=446.9 J
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic ... The different types of radiation are defined by the the amount of energy found in the photons.
Answer:
The most accurate and precise method to measure the thickness of a coin would be by a micrometer screw guage.
Answer:
Explanation:
The refractive index of a medium is given by the following formula:
where,
η = refractive index = 1.5
= angle of incidence = ?
= angle of refraction = 15°
Therefore,
