I can why do plants grow fast?
Answer:
See explanation
Explanation:
From Newton's law; the rate of change of momentum is proportional to the impressed force. Hence;
F.t = mv- mu
F= force
t= time
m= mass
V= final velocity
u = initial velocity
since u = 0, mv= 0
F= MV/t
F= 69.8 × 5.27/0.833
F= 442 N
Impulse = Ft= 442 × 0.833= 368 Ns
Solar winds contain high levels of radiation which could lead to various health related complications in living organisms on Earth. These complications include and are not limited to radiation sickness, chromosomal damage, and cancer. However, solar winds are blocked by the Earth's magnetic field, only posing problems to our telecommunications.
The answer is D. i got all the other ones wrong ._.
Answer:
Explanation:
Distance travelled by sound in going to target( insect ) and returning back = 2d ,d is distance of target .
time t = .06 s
speed = distance / time
344.9 = 2d / .06
d = 10.35 m
