Answer:
Explanation:
In standing wave pattern we find region of nodes where vibration is minimum or cold spots . The distance between any two consecutive node is half the wave length . There are 5 cold spot or node in between which is equal to 4 half wave length .
width of oven = 4 x half wave length
= 4 x (12 / 2 )
= 24 cm
Answer:
D. Wind and solar energy help save money and reduce air pollution.
Explanation:
Force = mass * acceleration
F = 15 *8 = 120 Newton
Answer:
The chemical equation for photosynthesis is 6CO2+6H2O→C6H12O6+6O2.
Explanation:
D= vt +.5at^2
since he started at rest, v (initial velocity) is 0
so d=.5at^2
d = .5 (6m/s^2) (4.1s)^2
then put that into a calculator.
