Answer:
This question appear incomplete
Explanation:
This question appear incomplete because of the absence of the time the honeybee spent while travelling from the hive. However, if we are to assume that the honeybee spent the same amount of time leaving/travelling as when it was returning. Then the formula to be used is
Speed = distance ÷ time
distance = speed × time
distance = 4 × 1
distance = 4 miles
To determine the displacement of the honeybee, the total distance covered by the honeybee in both to and fro journey will have to be summed (this is because displacement is a vector quantity).
Assuming the the speed and time spent while returning is the same with those spent while leaving, then the displacement will be distance × 2 (sum of all the distance covered)
Thus; 4 × 2 = 8 miles
Answer:
15.Radiowave
16.laser is device that generates an intense beam of other electromagnetic radiation by emission of photons from excited atoms.
17.this is a laboratory instrument commonly used to display and analyse the waveformof electronic signals.
19. this is a space entirely devoid of matter.
Assuming that what you typed meant 20 seconds, rather than 2o seconds, the car is travelling at a velocity of 200 meters per second.
Answer:
Written in Python
def energyvector(mass):
c = 2.9979 * 10**8
energy = mass * c ** 2
print(round(energy,2))
Explanation:
This line defines the function
def energyvector(mass):
This line initializes the speed of light
c = 2.9979 * 10**8
This line calculates the corresponding energy
energy = mass * c ** 2
This line prints the calculated energy
print(round(energy,2))
