We would have solar or lunar eclipses every month because the sun earth and moon would all line up because the moon wouldn’t be tilted in the same plane as the earth
The correct answer to the question is : D) Impulse
EXPLANATION:
Before going to answer this question, first we have to understand impulse.
Impulse of a body is defined as change in momentum or the product of force with time.
Mathematically impulse = F × t = m ( v - u ).
Here, v is the final velocity
u is the initial velocity
F is the force acting on the body for time t.
Hence, the perfect answer of this question is impulse m i.e the force multiplied with time is known as impulse.
When light ray pass from air into water, its speed and wavelength change only the frequency of the light doesn't change.
Light travels slower in a medium of higher refractive index. It bends because of this change in speed. The wavelength of light also changes in order to maintain the constant frequency.
P (gravitational force) = m (mass) x g
<=> P = 0.05 x 10
<=> P = 0.5N
Answer:
Archaeology
Explanation:
Radioisotopes are radioactive atoms of an element in which their atoms contain excess energy making them unstable. When broken down they become more stable releasing radiations.
Carbon 14 is a radioactive isotope that is used in archaeology to study and estimate the lifespan and age of organic materials such as wood, leather. Carbon 14 can be used to estimate the ages of materials up to 50000 to 60000 years.
