D
Explanation:
A is wrong bc best DNA will survive
B is wrong because organism adapt not only for food source but to be able to live in the environment as well
C is wrong because single celled organisms don't adapt
Answer:
2.019 seconds.
Explanation:
Here we use the equation:
Distance covered = (initial speed x time) + 0.5 x (acceleration x time^2)
The vertical distance to cover is 20 meters.
Since the cannonball is fired horizontally, the initial vertical speed is 0 m/s.
Acceleration due to gravity is 9.81 m/s^2.
Substituting these values into the equation we get:
20 = (0 x time) + 0.5 x (9.81 x time^2)
Solving this equation for time gives us 2.019 seconds as the answer.
A continually rotating magnetic field would continuously induce current, the induced current would show alternating direction
Answer:
Explanation:
According to the definition of refractive index, the refractive index of the material is defined as the ratio of speed of light in vacuum to the speed of light in medium.
(a) refractive index, n = 1.52
(b) refractive index, n = 1.51
(c) refractive index, n = 1.36
Energy can be measured as work. We can write energy = force x distance. Thus SI derived unit of energy has the units of newtons x meter or kg m2/s2.
