Answer:
f2 = 140 Hz
Explanation:
let fundamental frequency is f1 = 70.0 Hz
formula for finding the higher frequency when fundamental frequency is known
fn = n f1 (where f1 is fundamental frequency and n = 1,2,3,4,5...........)
for the second frequency n=2
f2 = 2 × 70.0 Hz
f2 = 140 Hz
Answer:
False
Explanation:
It is not necessary, that when the initial speed of the object is zero then it must be at origin.
It may be the object starts motion from the left of origin.
We eat plants that use the energy from the sun to make food
Answer:
C voltage
Explanation:
Voltage is the change in electric potential so basically current flows from high potential to low potential due to voltage.
Answer:
Food mixer will convert electrical energy into kinetic energy
Explanation:
Energy conservation means that energy can not be created nor destroyed it can be converted from one form into another
